Meanwhile, FIGS. 10, 13, 18, and 21 are an overall configuration for executing the meta information-based keyword advertisement service method included in the video information in the video multimedia content service system of the present invention, and the respective components constituting the entire configuration. The detailed configuration of the partial system.

In order to implement the present invention, 1) a user computer 9000, 2) a multimedia content service system 1000, a keyword advertisement content providing system 3000, and a wired / wireless network 8000 are necessary. In some cases, at least One or more meta information-based keyword advertisement mediation systems 2000 are required. Hereinafter, each system, a server included in each system, each system and / or each function module included in each server, and each DB (database) will be described in detail.

Keyword advertising content provision server (3100)

The keyword advertising content providing server 3100 is included in the keyword advertising content providing system 3000. The presence form of the keyword advertisement content providing server 3100 may include an external keyword advertisement content providing server type outside the multimedia content service system 1000 and an internal keyword advertisement content existing inside the multimedia content service system 1000. There may be a provisioning server type. Being in the interior means that the identity of the operator of the multimedia content service system 1000 and the operator of the keyword advertisement content providing server 3100 are recognized. On the other hand, being outside is a case where the identity or the affinity of the subject is weak or absent, or only in a partnership relationship.

On the other hand, from the standpoint of the implementation of the present invention, the distinction between the internal and the external is not significant, and it is distinguished in order to reduce the confusion resulting from the display of the inclusion relationship on the configuration diagram of the whole system or service. Most online operators do not have a keyword advertising content providing server 3100 therein. Examples of popular keyword advertisement content providing server 3100 include www.google.com and www.overture.com. Since large sites such as www.google.com provide not only multimedia contents but also keyword advertisement contents, in terms of the multimedia contents service system 1000 included in www.google.com, the keyword advertisement contents providing system 3000 is internally provided. Will be an integrated form that includes Such a type as www.google.com is referred to herein as a unified model type.

A person who operates the keyword advertisement content providing server 3100 typically owns the advertiser network 8000 directly or indirectly. The advertisers inform the operator of the keyword advertising content providing server 3100 of their keyword advertising content (the title of the advertisement, the description of the advertisement, the URL, the image for the purpose of advertising, and / or other text for the purpose of advertising; At least one of the text content) is registered. The keyword advertisement content providing server 3100 may extract keyword advertisement content corresponding to the keyword when the user inputs a specific keyword or the user receives the input keyword. Furthermore, the keyword advertisement content providing server 3100 may extract the extracted keyword advertisement content directly (on a site operated by the operator) or indirectly (on a site operated by a third party other than the operator). Allow exposure. The operator of the keyword advertisement content providing server 3100 requests the advertisers to pay the advertisement cost for the keyword advertisement content when the users click on the keyword advertisement content or generate an advertisement effect in exchange for the exposure. We assume main business contents. The keyword advertisement content providing server 3100 constructs a DB of the title of the advertisement, a description of the advertisement, or other text contents of the keyword advertisement content in a DB or a search index, and executes the received text query (keyword query, etc.). After querying through a DBMS or a search engine, the keyword advertisement content corresponding to the query result is extracted, and the keyword advertisement content satisfying all or a predetermined criterion of the extracted keyword advertisement content is provided to the queryer (computer).

The present invention deals with the keyword advertising content among the advertising content. The keyword advertisement content refers to advertisement content that is associated with, searched for, or called by a keyword in the form of a search word / query or other text (including a tag and a description) among the advertisement contents. The keyword advertising content is typically in the form of a text, an image such as a banner, or does not exclude the form of an image, sound, etc., the text, image, image and / or sound may be combined at least one.

When the keyword advertisement content providing server 3100 receives a string of at least one text from a specific server / client, the keyword advertisement content providing server 3100 processes the received string (at least one keyword advertisement target text of the present invention) to correspond to the string. The server performs a function of searching whether there is keyword advertising content, and providing the keyword advertising content to the server / client when there is keyword advertising content.

The keyword advertisement content providing server 3100 may be a keyword advertisement content providing server-side text acquisition module 3110 that receives text and / or keyword advertisement target text (hereinafter, referred to as a text acquisition module 3110 or a keyword advertisement content providing server-side text). This is called an acquisition module 3110. This is completely different from the non-tag text acquisition module 5130 in the meta information acquisition module 5100 described below.), And the keyword advertisement content DB 3120 storing keyword advertisement content. ), A keyword advertisement content providing server-side keyword advertisement content transmission module 3130 for transmitting keyword advertisement content obtained from the keyword advertisement content DB 3120 with respect to the obtained text and / or keyword advertisement target text. . The keyword advertisement content providing server-side keyword advertisement content transmission module 3130 logically or physically transmits the keyword advertisement content to its outside. Meanwhile, the keyword advertisement content transmission module such as the keyword advertisement content providing server-side keyword advertisement content transmitting module 3130 performs an equivalent function regardless of a logical or physical location, and the meta information-based keyword advertisement mediation server 2100 described later. ) Performs the equivalent function to the keyword advertising content transmission module 8800, and they are only distinguished by the difference of the higher concept to which they belong, and their function is equivalent.

At this time, a method of extracting the appropriate keyword advertising content from the received text and / or keyword advertisement target text is largely a method using a DBMS or a method using a search engine. The keyword advertising content includes information in various letters, numbers, and / or symbols, including the title of the advertisement, description of the advertisement, URL, other text, and the like. , May be indexed by an indexer. When there is at least one multimedia content and various kinds of information related to the multimedia content, it may be constructed as a DB, the information required in the DB may be obtained by a query method, or the various information may be constructed as an index, and a search query may be obtained. At this time, searching for it by a searcher or the like is obvious to those skilled in the art, and thus detailed description thereof will be omitted. Of course, the keyword advertisement content DB 3120 includes information on an advertiser registering a specific keyword advertisement content, information on an advertisement price (the advertisement price can be changed in real time), information on an advertisement cost generating condition, an advertiser. Any of the following: information on the advertising balance of the advertiser, information on the advertising spend of the advertiser, management information on the occurrence of advertising, policy information on the operation of advertising, policy information on the allocation of advertising costs, fraudulent advertising exclusion policy, and conditions It may contain the above.

Multimedia Content Services Server (1100)

Multimedia content service system 1000 and multimedia content service server 1100

The multimedia content service system 1000 includes a multimedia content service server that serves multimedia content. The multimedia content service server 1100 includes a multimedia content DB 1110 and conceptually includes video content. Video content DB 1111, image content DB 1112 containing content in photographic or other image formats, sound content DB 1113 containing music, songs, sound effects or other sound content, articles or news It includes one or more of the text-centric content DB 1114, other multimedia content DB 1115 that includes the content of the text, such as the center. The multimedia content DB 1110 further includes at least one multimedia content file, meta information of the multimedia content file, and management information about the multimedia content file. The multimedia content service system 1000 may provide the multimedia content and other multimedia content related services to a user computer 9000 accessing the multimedia content to the multimedia content service system 1000 through a wired or wireless network 8000. Can be. In this case, when the multimedia content service system 1000 provides a service through a web method, a web server is required. When the multimedia content service system 1000 provides a service through another third method (for example, a WAP method), It will be apparent to those skilled in the art that a corresponding server is required. In the description of the present invention, the description will be made based on the web method, but this is for convenience of notation, and it is natural that the web method is only one example of a communication method, and it is natural to understand that it includes other wired / wireless Internet / non-Internet communication methods. will be.

Meta Information of Multimedia Content

The meta information included in the multimedia content includes meta information related to the content of the multimedia content. An identifier (ID), a title, a tag, a category (classification information), description information, and other multimedia content service system 1000 of the multimedia content. At least one of the processing information of the) is included. Table 1 shows an example of what meta information is included in the multimedia content. Meanwhile, meta information of the multimedia content file itself may include any one or more of a file size, a play time, a file position, and an acquisition time of the multimedia content file, and are generated in a relationship between the multimedia content file and the user. There may be log information about the multimedia content file, such as the number of times of inquiry of the multimedia content file, a search time, and derivative content such as comments provided by users with respect to the multimedia content file. An example of the meta information included in the multimedia content as described above will be found in Table 1 below. Table 1 below is an example of the multimedia content DB 1110, and it can be seen that various meta information about multimedia content is included.

TABLE 1

ID + Title tag category File path Explanation Play time The # 1 ghost is also in the printer Office Worker Ghost Printer New Employee Refill Ink Movie & Animation ... / Z74HJQY_t8Q There's nothing strange about a new employee and no ghost anywhere ... Refill ink, fade away. 1 minute 30 seconds # 2 Testimony of Lawyer Kim Kyung-joon Kim Kyung Joon Choi Jae Kyung Oh Jae Won Lee Myung Bak BBK News & Politics ... / 7nCBiSaZeJA Attorney "One BBK office printer is inkjet" Prosecutor "No inkjet behind office" 3 minute, 20 seconds # 3 genuine ink vs infinite ink Refillable Ink Original Ink Ink Ink Printer All-in-One Printer Know & Style ... / Kn0sA26X_YE I knew if genuine ink is good, but I didn't know the difference. 5 minute, 10 seconds .

The screen associated with the video shown in FIG. 2 relates to the multimedia content ID 3 of Table 1 above.

In this case, when the multimedia content service system 1000 directly generates the multimedia content, the multimedia content service system 1000 may generate the meta information, but the multimedia content creators may generate the multimedia content. In the case of upload to file transfer, the title, tag, and descriptive information may be provided by the creator. When the creator selects at least one category for the multimedia content provided by the creator according to a predetermined classification criterion, the selected category information is also meta information. On the other hand, if the multimedia content service system allows users who are not creators to provide or add tags, description information, categories, etc. to the multimedia content provided by the creator, such tags, description information, etc. may also be added to the meta information. Will be included. Examples of the meta information may be found in FIGS. 2, 4, 6, and 7 to 9.

Type of multimedia content

Meanwhile, the multimedia content includes a video multimedia content centered on a video, an image multimedia content centered on an image, a sound multimedia content centered on a sound, a text multimedia content centered on a text, and the other text, images, sound, and the like. Multimedia content including at least two or more videos. In the present invention, the idea of the present invention will be mainly described based on moving picture multimedia contents, but it will be apparent that the present invention is not limited to moving picture multimedia contents. In general, a method of servicing a video multimedia content is a method of transmitting a video multimedia content file to a user computer 9000 by streaming or the like on a server side, and a method of transmitting the video multimedia content file itself to a user's computer. There is this. Both of these methods apply equally to sound multimedia content. Although the present invention will be described with reference to the former, it will be obvious to those skilled in the art that the present invention can be applied to the latter.

 In this case, the multimedia content transmission module 1120 may be included in the multimedia content service server 1100 for transmission of the video multimedia content file in a manner such as streaming. In general, in the case of an image multimedia content file, the image multimedia content file itself may be transmitted to the user computer 9000 without the concept of reproduction. However, even in such a case, since the file format of the image multimedia content file generated by the multimedia content creator is often not viewable on the user's computer 9000, the multimedia content is typically used. The service server 1100 may convert the image multimedia content file generated by the creator to be played in a typical browser. The conversion may also be applied to video multimedia content or sound multimedia content. Meanwhile, the multimedia content service server 1100 may generate a thumbnail image for the multimedia content generated by the creator, and the thumbnail image may appear as a result of the user searching for the multimedia content for the multimedia content. Also do.

Meta Information Based Keyword Ad Server (6000)

Next, the meta information-based keyword advertisement server 6000 of the present invention will be described in more detail with reference to FIG. 10. The meta information-based keyword advertisement server 6000 includes a meta information acquisition module 5100 for acquiring meta information of multimedia content, and a keyword advertisement control module 6900 for controlling keyword advertisement according to the present invention. The keyword advertisement display module 7900 may perform a role according to various methods of displaying keyword advertisement content.

Meta Info Get Module (5100)

The meta information acquisition module 5100 may include a tag information acquisition module 5110 and a non-text information acquisition module 5120 and text information other than a tag for receiving tag information in at least one text format included in the multimedia content. There is a non-tag text acquisition module 5130 to obtain. As the information obtained by the meta information acquisition module 5100, the play time information of the multimedia content is important. The non-tag text acquisition module 5130 obtains all text information except tag information among information on the multimedia content.

For example, the tags in the ID 3 multimedia contents of FIG. 2 and Table 1 include "refill ink, genuine ink, infinite ink, printer, multifunction printer, ink", and the like. The tag information acquisition module 5110 of the meta information acquisition module 5100 receives the "refill ink, genuine ink, infinite ink, printer, multifunction printer, and ink". On the other hand, the non-tag text acquisition module 5130 obtains the title of the video "Genuine Ink VS Infinite Ink", the description "Genuine Ink is good, but did not know the difference to this extent." In this case, when the tag information acquisition module 5110 receives at least one tag information, the non-tag text acquisition module 5130 may not function. That is, the tag information acquisition module 5110 and the non-tag text acquisition module 5130 may obtain meta information at the same time, but the tag information acquisition module 5110 first tries to obtain information, and then the tag information acquisition module. When the information obtained by the 5210 is not available, or the information obtained by the tag information obtaining module 5110 is a preset criterion (the tag information obtained by the tag information obtaining module 5110 cannot generate the keyword advertisement target text) If the same situation condition does not occur), the non-tag text acquisition module 5130 may be operated in subordinate order. Meanwhile, when there is a commercial tag, the tag information acquisition module 5110 may obtain the commercial tag as one kind of tag. Professionally performing the function of acquiring the commercial tag is called a commercial tag set obtaining module 5140 and is well illustrated in FIG. 27. When there is a commercial tag set in the video information of the multimedia content DB, the tag information obtaining module 5110 preferentially obtains a commercial tag included in the commercial tag set in preference to a conventional tag. Meanwhile, when the commercial tag set includes a time dependent commercial tag and a time independent commercial tag together, the time dependent commercial tag is preferentially obtained during the playback time by syncing / synchronizing with the playback time of the video. If this is done, the time-independent commercial tag will be available first. Hereinafter, since the tag information obtaining module 5110 processes the information about the commercial tag or the commercial tag set, the description thereof is the same or equivalent, and thus, repeated description thereof will be omitted.

Obtaining Meta Information Included in Selected Multimedia Content

When the multimedia content service server 1100 receives selection information on at least one multimedia content from a user computer 9000, the multimedia content DB may include selection information about the multimedia content and / or meta information of the multimedia content. Obtained from 1110, the meta information-based keyword advertisement server 6000 is transmitted. The meta information acquisition module 5100 of the meta information-based keyword advertisement server 6000 obtains meta information of the selected multimedia content. The meta information is obtained by 1) a method in which the meta information-based keyword advertisement server 6000 is received from the multimedia content service server 1100, and 2) an ID of the multimedia content in which the meta information-based keyword advertisement server 6000 is selected. May be obtained, and the multimedia content DB 1110 may be inquired and obtained by the ID of the multimedia content. The latter is preferable when the meta information-based keyword advertising server 6000 is easily allowed to access the multimedia content DB 1110, and the former may be sufficiently considered because the amount of data to be transmitted is small. On the other hand, if it is difficult for the meta information-based keyword advertising server 6000 to directly access the multimedia content DB 1110, the method should be the former method. The tag information acquisition module 5110 obtains tag information included in meta information of the multimedia content. In this case, when there is no tag information in the multimedia content, the non-tag text acquisition module 5130 obtains and processes text information from the meta information. Of course, the non-tag text acquisition module 5130 may optionally obtain the text information from the meta information independently of the presence or absence of tag information of the multimedia content. The non-tag text acquisition module 5130 will be described later in detail.

Keyword Ad Control Module (6900)

The keyword advertisement control module 6900 generates an advertisement target text from the meta information obtained from the meta information acquisition module 5100, queries the keyword advertisement content providing server 3100 with the advertisement target text, and executes the keyword advertisement. Receives keyword advertising content directly from a content providing server 3100 or via a third server, and processes the keyword advertising content to display the keyword advertising content on a user computer 9000. .

Configuration of Keyword Ad Control Module 6900

The keyword advertisement control module 6900 may generate a keyword advertisement target text generation module 6610 for generating an advertisement target text using meta information of the received multimedia content, and transmit the keyword advertisement target text to the keyword advertisement content providing server 3100. The keyword advertisement target text transmission module 6520, the keyword advertisement control policy DB 6640 storing the policy of operating the keyword advertisement control module 6900, and the keyword advertisement content providing server 3100 may obtain keyword advertisement content. The received keyword advertisement contents acquisition module 6630 and the keyword advertisement contents selection module 6550 for selecting keyword advertisement contents to be displayed on the user computer 9000 among the received keyword advertisement contents.

The keyword advertisement control module 6900 receives meta information obtained by the meta information acquisition module 5100. When there is a tag obtained by the tag information acquisition module 5110, the keyword advertisement control module 6900 assigns and stores codes for the n (n is natural numbers) tags. For example, if there are six tags obtained from a particular multimedia content as "refill ink, genuine ink, infinite ink, printer, multifunction printer, ink", they may be stored as tag1, tag2, ... tag6 in order. .

Keyword Ad Target Text Generation Module (6510)

The keyword advertisement target text generation module 6610 of the keyword advertisement control module 6900 generates keyword advertisement target text with reference to the keyword advertisement control policy DB 6640. If there is a tag obtained by the tag information acquisition module 5110, the keyword advertisement control policy of the keyword advertisement control policy DB 6640 generates the keyword advertisement target text using only the tag, and replaces all of the tags with the keyword advertisement target text. When the policy to generate is taken, the keyword advertisement target text generation module 6610 of the keyword advertisement control module 6900 may generate all tag information in the received meta information as keyword advertisement target text. In this case, the keyword advertisement target text is generated as the keyword advertisement target text of the tag obtained by the tag information acquisition module 5110. That is, the function of the keyword advertisement target text generation module 6510 in this case is to treat the obtained tags as keyword advertisement target text without performing any processing on the tags obtained by the tag information acquisition module 5110. do.

Therefore, in this case, although conceptually distinguished in the information processing step, the meta information obtained by the tag information acquisition module 5110 becomes the keyword advertisement target text as it is. Therefore, the meta information acquisition module 5100 (or the tag information acquisition module 5110) and the keyword advertisement target text generation module 6510 are functionally the same module, or the meta information acquisition module 5100 is a keyword advertisement. It should be considered that the target text generation module 6510 or the keyword advertisement target text generation module 6510 is included in the meta information acquisition module 5100. However, treating the meta information obtained by the meta information acquisition module 5100 (tag information acquisition module 5110) as the keyword advertisement target text as it is may be treated as a function of the keyword advertisement target text generation module 6510. If possible, the meta information acquisition module 5100 and the keyword advertisement target text generation module 6510 may be recognized as functionally independent modules as well as concepts. Of course, in this case, when the keyword advertisement target text generation module 6510 selects one or more of the obtained n tags or changes the order of the tags, the meta information acquisition module 5100 and the keyword advertisement are selected. The target text generation module 6510 will be different.

The keyword advertisement target text generation module 6510 may form the obtained n tags into at least two groups. For example, when the keyword advertisement target text generation module 6510 selects all six tag information among the six tag information such as "refill ink, genuine ink, infinite ink, printer, multifunction printer, ink", the ink is selected from the six tags. "Refill Ink, Original Ink, Infinite Ink, Ink" can be created in one group, and "Printer" and "All-in-One" can be divided into three groups and sent in each group unit. .

There can be many policies that are created as a group, one of which is a method of combining common words / phrases / vocabulary, and the other is referring to a thesaurus DB or other synonyms / synonyms / thesaurus dictionary DB. There is a way to group. The former example has been described, and the latter example allows the keyword advertisement target text transfer module 6520 to determine that "printer" and "multiplexer" are homogeneous by querying a thesaurus DB or other synonyms / synonyms / related words dictionary DB. If so, you can group them as "printers, multifunction devices".

The advantages of grouping are: 1) it allows users to show ads related to one concept / homolog at a time; 2) it is easy to replace ads when there are no clicks on ads exposed to the user, 3) When there is a click in a group, there are various advantages such as providing various advertisements corresponding to the tags in the group.

Further explanation is as follows. In general, the higher the price among the m keyword advertisement contents provided by the keyword advertisement content providing server 3100, the higher the advertisement price or the higher the click-to-impression ratio, thereby making a greater contribution to the generation of advertisement revenue. In this case, in relation to 1), when the keyword advertisement content providing server 3100 processes the refill ink, genuine ink, infinite ink, and ink at once, the keyword advertisement content providing server 3100 may process the same. For the four keyword advertisement target texts, the top keyword advertisement contents having a high average advertisement price or a high click-to-impression ratio can be selected. On the other hand, in relation to 2) above, if the user is not interested in the advertising on ink, the keyword advertising content needs to be replaced. If not, there is a need to provide a second group of keyword advertising content. At this time, if the group unit is not adopted, the user will continue to be provided with the keyword advertisement contents corresponding to the "refill ink, genuine ink, infinite ink, ink", and there is a high possibility that there will be no clicks on the keyword advertisement contents. As a result, the expectation of the generation of advertising revenue is much lower. On the other hand, in relation to 3) above, if the user clicks on the keyword advertisement content group m1 exposed to the user for "refill ink, genuine ink, infinite ink, ink", the user "ink" May be of interest to you, such as replacing, rolling, or replacing the keyword ad content group m2 that is not exposed to more users related to " refilled ink, genuine ink, infinite ink, inks " Can be provided as The average estimated ad revenue for the m2 keyword ad content group for "Refilled Ink, Genuine Ink, Infinite Ink, Ink" may be lower than the m1 keyword ad content group, but if a click comes from the m1 keyword ad content group, It can be inferred that the average predicted ad revenue in the relevant m2 keyword ad content group will be higher than the "all-in-one" or "printer". Of course, when the grouping is performed, a group identifier such as a group ID may be further combined with each of the keyword advertisement target texts. Whether or not a click has occurred with respect to the keyword advertisement content transmitted to the user is performed through the click generation information receiving module 8900 or the click generation information transmitting module 9900 of the present invention. At this time, whether to generate the keyword advertisement target text in the group unit, etc., according to the keyword advertisement control policy of the present invention, the keyword advertisement control policy is stored in the keyword advertisement control policy DB 6540.

Meanwhile, when the keyword advertisement target text generation module 6510 obtains a commercial tag, the keyword advertisement target text generation module 6510 may preferentially handle the conventional tag. In particular, when the meta information obtained in the at least one commercial tag has a high score function to be described later, or information about passing the criterion of verification with a high difference in the process of generating the commercial tag, the commercial tag is further included. High weights. On the other hand, the keyword ad target text generation module 6510, in the commercial tag with any one or more of 1) a typical user input tag, 2) title information, if there is overlap, more priority or more than other commercial tags High weights.

Keyword Ad Target Text Transfer Module (6520)

 On the other hand, the keyword advertising target text transmission module 6520 of the keyword advertising control module (6900) for the generated keyword advertising target text there are two ways to send a query to the keyword advertising content providing server 3100 have. One is a temporary transmission method in which the keyword advertisement target text transmission module 6520 transmits the entire generated keyword advertisement target text at one time. .

As an example of the group-based query transmission method, the keyword advertisement target text transmission module 6520 transmits the generated keyword advertisement target text one by one. In this case, when the keyword advertisement content providing server 3100 fails to accommodate a plurality of keyword advertisement target texts, the keyword advertisement content providing server 3100 may not use the former method and transmit one of the latter methods.

In this case, when the keyword advertising content providing server 3100 has a predetermined interface standard of a web service or SOA method, or when the keyword advertising content providing server 3100 employs a unique API, the keyword advertising control module 6900 processes the query including the keyword advertisement target text generated by the keyword advertisement target text generation module 6510 so as to meet the preset interface criterion or according to a method defined by the API. In this case, it is preferable that the query and the received keyword advertisement contents are in an XML manner. The keyword advertisement content acquisition module 6630 of the keyword advertisement control module 6900 may transmit the meta information to the query transmission request data transmitted by the keyword advertisement target text transmission module 6520 to the keyword advertisement content providing server 3100. It is necessary to include the IP of the base keyword advertising server 6000 or the address on the network 8000 to receive the keyword advertising content data. In this case, the query transmission request data may further include the maximum number of requested keyword advertisement contents for each transmission unit for each keyword advertisement target text or a plurality of keyword advertisement target texts forming a transmission unit. On the other hand, when the keyword advertisement content providing server 3100 provides the keyword advertisement content with information such as an advertisement price at the time of click or impression and / or an estimated click-through rate compared to the impression, the request for requesting such information in the query transmission request data is also included. Even more preferred. Meanwhile, when the keyword advertisement content providing server 3100 separately processes a plurality of keyword advertisement target texts for each keyword advertisement target text and transmits keyword advertisement contents for each keyword advertisement target text, the meta information. It is even more preferable that the based keyword advertising server 6000 transmits several keyword advertising target texts at once, rather than transmitting the individual keyword advertising target texts to the keyword advertising content providing server 3100 one by one.

Keyword Ad Content Acquisition Module (6530)

When the keyword advertisement content providing server 3100 receives at least one keyword advertisement target text from the keyword advertisement target text transmission module 6520, and there is at least one keyword advertisement content corresponding to the keyword advertisement target text. The keyword advertisement content is transmitted to the meta information-based keyword advertisement server 6000 in a predetermined manner. On the other hand, if there is no keyword advertising content, information on the absence of keyword advertising content is transmitted to the meta information-based keyword advertising server 6000, and the meta information-based keyword advertising server 6000 transmits another keyword advertisement text to the keyword. The advertisement content providing server 3100 may transmit the same. In this case, when the keyword advertisement content acquisition module 6630 of the keyword advertisement control module 6900 of the meta information-based keyword advertisement server 6000 receives at least one keyword advertisement content from the keyword advertisement content providing server 3100. The keyword advertisement content acquisition module 6630 adds and stores a code to the received keyword advertisement content.

Keyword Ad Content Selection Module (6550)

Subsequently, the keyword advertisement content selection module 6550 selects keyword advertisement content with respect to the received at least one keyword advertisement content by referring to the keyword advertisement control policy DB 6540. In this case, when there is only one keyword advertisement content, only one keyword may be selected. However, when there are a plurality of keyword advertisement contents, a policy for selecting keyword advertisement contents becomes more important. In this case, for example, when the keyword advertising content selection module 6650 has a policy of selecting max three pieces in front of the plurality of received keyword advertising contents in order, the selected keyword advertising contents are three selected. If within 3, select 3, and if exceeding 3, select 3 from the front.

Asynchronous keyword ad content delivery

When the keyword advertisement content selected by the keyword advertisement content selection module 6550 is transmitted to the multimedia content service server 1100, the multimedia content service server 1100 transmits the keyword advertisement content to the user computer 9000. . There are two ways to transmit the multimedia content. First, a web page configured to include the selected keyword advertisement content to be provided to the user computer 9000 together with the multimedia content is transmitted to the user computer 9000 through the web server. In this case, the multimedia content area and the keyword advertisement content display area are separated from each other in the web page, and the two areas are each asynchronous (not controlled in a group, but controlled independently by a server). It is preferable to operate as. The asynchronous method means that the multimedia content area and the keyword advertisement content area are controlled independently of each area (data transmission with a server, etc.) that together form a page. The advantage of this asynchronous method is that it takes a long time to obtain the keyword advertising content from the keyword advertising content providing server 3100 and provide it to the user computer 9000, or to roll the keyword advertising content or the user's behavior. This is particularly useful when trying to control the display of the keyword advertisement content depending on whether information is available. For example, when the user selects the multimedia content, the user computer 9000 first provides information about the multimedia content, and then transmits at least one keyword advertisement content to the keyword advertisement content area. Of course, data of the multimedia content area and the keyword advertisement content area may be transmitted in a synchronous manner, and the keyword advertisement content information may be transmitted preferentially. That is, in the spirit of the present invention, it is essential that the information of the multimedia content area and the information of the keyword advertisement content area maintain a strong association in the content, and the order and method of providing each area may vary. Of course, in a case other than the web method (a method of processing information by a mobile phone or other non-web method), the data provided to the user computer 9000 is generated according to the method. Second, the web page related to the multimedia content is first provided to the user computer 9000, and the keyword advertisement content selected by the keyword advertisement content selection module 6550 is transmitted to the web page where the connection is maintained. It is a way of giving. The second method is more effective when the acquisition of the keyword advertisement content to be provided to the user is slow, or when the keyword advertisement content is transmitted after a certain time has elapsed. On the other hand, it is preferable to use asynchronous communication in the case of the second method, which has been described in the first case.

Keyword Ad Control Policy and Keyword Ad Control Policy DB (6540)

Next, the keyword advertisement control policy and the keyword advertisement control policy DB 6540 will be described in more detail. The keyword advertisement control policy includes the following information, and the situation and processing method for processing the above information by the meta information-based keyword advertisement server 6000 will also be described.

About keyword ad target text generation criteria scope policy

First, generating keyword advertisement target text that determines whether to use only the information obtained by the tag information acquisition module 5110 or even the module obtained by the non-tag text acquisition module 5130 as information necessary for generating keyword advertisement target text. Reference range policy information. The variable included in the policy information may be one or more of 1) presence of tag, 2) number of tags, 3) number of keyword ad contents for each tag, 4) number of total keyword ad contents, and 5) duration of multimedia content. Can be. For example, if the number of tags is only one, or if the number of tags is large, but there is no keyword advertising content provided from the keyword advertising content providing server 3100 for the tag, or the number is less than or equal to a predetermined criterion, Alternatively, if the keyword advertising content is a small number (for example, about three) or if the playing time of the multimedia content is long, it may be necessary to generate additional keyword advertising target text in addition to tag information. In this case, the meta information-based keyword advertisement server 6000 obtains tag information about meta information included in the multimedia content in the multimedia content service server 1100, and, if the tag information exists, the tag information. The maximum number of keyword advertisement contents that can be obtained is inquired by any one of the temporary transmission method and the plurality of group transmission methods. If the inquiry results do not meet the predetermined requirements, the non-tag text acquisition module 5130 is instructed to operate. Operation of the non-tag text acquisition module 5130 will be described later. The predetermined requirements include 1) the absolute number of keyword advertising contents, 2) the absolute number of keyword advertising contents compared to the playing time of the multimedia contents, and 3) the keyword advertising contents when the advertising cost information for the keyword advertising contents is included. Absolute amount of advertisement cost information for each advertisement content, and 4) click-through rate for each of the keyword advertisement contents (click on the user's interaction information about the keyword advertisement contents transmitted from the user computer 9000 such as a click). Other interactions). That is, even if the keyword advertising content is greater than or equal to the reference number, the advertising cost and / or clickthrough rate for each of the keyword advertising content is lower than or equal to a predetermined criterion, and the expected advertising yield is lower than or equal to the criterion. In this case, the non-tag text acquisition module 5130 operates to generate additional keyword advertisement target text, and it is necessary to obtain more keyword advertisement content with the generated keyword advertisement target text. As described above, the keyword advertisement control policy includes information on various branch conditions, variables, criteria, calculation formulas, and the like in relation to the generation of the keyword advertisement target text. This can be stored in the form of a DB. Examples of the branching condition include 1) presence of keyword advertisement content, 2) occurrence of click on keyword advertisement content, and 3) grouping. That is, if there is no keyword advertisement content for the keyword ad target text based on the tag information acquisition module 5110, the non-tag text acquisition module 5130 extracts the text and supplies the keyword advertisement content to the keyword advertisement content providing server 3100. It is necessary to make a request, and there is no click in a specific keyword ad content group, or a predetermined time (eg, 10 seconds or 30 seconds) or a predetermined time for playing the multimedia content based on the tag information acquisition module 5110. If a click does not occur within a flexible time such as 15% of time, etc., the keyword advertisement content of another group is provided, or the keyword advertisement content due to the non-tag text acquisition module 5130 is provided to the user computer 9000.

Policy information about weights

Second is policy information on weights. The creators of multimedia contents input or generate a plurality of tags and / or titles and description information related to their multimedia contents as meta information so that the multimedia contents can be searched and described well. Therefore, the tags are strongly related to the multimedia content, but it is difficult to say that all the plurality of tags have the same weight as the multimedia content. One of the reasons why search keyword ads have better advertising effects than banner ads is because the user's interests (search terms) are closely related to the ads. Common sense may be that tags at the forefront best represent the multimedia content, and even if the tag is not a tag, the target text extracted from the title information is more representative of the multimedia content than the description information. will be. In addition, it may be regarded that the keyword advertisement target text simultaneously displayed in the title and the tag best represents the multimedia content. Therefore, the weight policy is based on 1) the source of the text that is the target of the keyword ad text, 2) the order of the tags, 3) the number of keyword ad content for each of the keyword ad texts, and 4) the prediction of the keyword ad content for the keyword ad text. A criterion on revenue is needed. The estimated revenue may vary according to the advertising cost generation conditions, such as revenue per impression, revenue per click, etc. Revenue for each keyword ad content is a function of unit price for each keyword ad content, and whether or not the condition for generating advertising costs (exposure, click, etc.) is achieved. . Therefore, the keyword advertisement target text generation module 6610 of the meta information-based keyword advertisement server 6000 may generate the keyword advertisement target text with reference to the weight policy from the generation of the keyword advertisement target text.

According to the weighting policy, 1) the source of the text targeted for the keyword advertisement text is i) a weight of 5 for tags, ii) a weight of 3 for titles, or 8, iii) a weight of 1, iv for descriptions. In the case of a category, a weight of 0.5 may be an example. 2) An example of a weight policy for the order of tags includes i) equal weighting for all tags, and ii) ordering the tags based on a predetermined continuous or stepwise decreasing function such as y = 1 / x. An example is the case of inputting an independent variable (x) of a function and using the calculated function value as a weight. (If the above six tags are used and y = 1 / x is used, the first "refill ink" is used.) The weight for the other tags in the tag would be (1/1) * {1 / (1/1 + 1/2 + 1/3 + 1/4 + 1/5 + 1/6)}. The weighting model may be applied to a group as an example of the weighting of the group, i.e., i) and ii) for each group, or ii), but the number of tags belonging to the group is determined by the weight of the group. There may be a way to reflect on this. 3) For the number of keyword advertisement contents for each of the keyword advertisement target texts, i) equal weights, ii) y = f (x), and x are the number of keyword advertisement contents. For example, the method may be weighted according to the estimated revenue of the keyword advertising contents, and the estimated revenue of the keyword advertising contents may be generated based on the probability of generating the ad revenue such as the unit price of the keyword advertising contents, the share of the advertising costs, and the clickthrough rate to impressions. By a preset function that is combined from several variables, such as.

Meanwhile, the meta information-based keyword advertisement server 6000 generates as many keyword advertisement target texts as possible and maintains source information (tags, titles, and / or descriptions) of the generated keyword advertisement target texts. For each keyword advertisement content obtained for the keyword advertisement target text, the keyword advertisement content selection module 6550 may select the keyword advertisement content to be provided to the user computer 9000. In this case, the keyword advertisement content selection module 6550 may select a predetermined number of keyword advertisement contents with reference to the weight policy information.

About keyword ad content delivery policy

Third, the keyword advertisement content transmission method policy information of how the meta information-based keyword advertisement server 6000 transmits the obtained keyword advertisement content to the user computer 9000. The transmission method of keyword advertising contents includes 1) a policy regarding the number of keyword advertising contents to be transmitted in one transmission and an advertising scope of keyword advertising contents, 2) a policy regarding allowing renewal of transmitted keyword advertising contents, and 3) allowing renewal. 4) a policy regarding the renewal standard of 4), and a policy about maintaining the transmitted keyword advertisement content.

Policy on the number of one-time keyword ad content

The number of keyword ad contents to be sent in a single transmission is the environment in which the keyword ad contents are exposed (3 ~ 5 keyword ad contents may be exposed if the web screen is operated on a PC screen. If you're working on a screen, one or two is a good option, but on a PC screen, you can expose all the information (keywords, ad descriptions, URLs that go on click, etc.) of the keyword ad content being sent, In the case of a screen, etc., providing only a part of the headline or the description of the advertisement becomes the content of the keyword advertisement control policy, in which case there is information about the user computer 9000 accessing the multimedia content service server 1100 (especially, Display size information, resolution information, etc.), based on this In the meantime, the same multimedia content service server 1100 may provide the same or equivalent multimedia content in different resolutions according to the environment of the user computer 9000 (PC or mobile phone). The meta information-based keyword advertisement server 6000 obtains information about the environment of the user computer or the computer from the multimedia content service server 1100, and queries the keyword advertisement control policy based on the obtained criteria. The keyword advertisement contents of the number of keyword advertisement contents and the range of the advertisement contents may be provided to the user computer 9000. When the keyword advertisement contents are transmitted in one keyword advertisement content unit, the click is generated in the keyword advertisement contents. Keyword ad content that you receive will be replaced with other keyword ad content. This is particularly suitable as a method of transmitting the keyword advertising content in a mobile phone or other computer having a small display size.

Renewal policy for keyword ad content

Then, under the policy and under what conditions to allow the renewal of the keyword advertising content to replace the initially transmitted keyword advertising content with other keyword advertising content during the playing time of the multimedia content. A policy regarding whether to maintain the keyword advertising content may form the keyword advertising control policy. When the keyword advertising content of the first group consisting of at least one is transmitted, it may not be replaced with the keyword advertising content of another group during the playing time of the multimedia content, but may replace the entire keyword advertising content prepared in a predetermined time unit. have. In this case, as a policy for a predetermined time unit, 1) when the total playing time is T and the number of prepared keyword ad content groups is n, a method of exposing each keyword ad content group for a time of T / n. 2) There is a method of exposing a high weight keyword ad content group for more than T / n and a low weight group for a shorter time than T / n. However, when the minimum exposure time t of the keyword advertisement content is determined, 1) and 2) are applied when T / t is larger than t. On the other hand, when T / n is less than t, the minimum exposure time of the keyword advertising content is preferably t or T (when t> T). If the click occurrence information for a specific keyword ad content group is not obtained from the user computer 9000, the content of the keyword ad content transmitted to the user computer 9000 is changed to another keyword ad content group after a predetermined time unit elapses. In this case, the exposure time of the specific keyword advertisement content group or the like and whether a click occurs may be the contents of the keyword advertisement control policy for the change criteria. On the other hand, when the user's click information on the specific keyword ad content is obtained, the weight of the keyword ad text associated with the keyword ad content from which the click information is obtained may be increased, and the keyword associated with the high keyword weighted ad text It is preferable that the exposure time of the advertisement content is longer than the exposure time of the keyword advertisement content associated with the keyword advertisement target text where no click occurs. On the other hand, when the multimedia content is an image, the playing time T is 1) responding to the user computer 9000 for the specific image multimedia content, and then selecting information on additional image multimedia content from the user computer 9000. 2) a time until receipt of the content, or 2) a time for which the page regarding the specific image multimedia content is maintained in the user computer 9000. That is, while the page related to the specific image multimedia content is maintained in the user computer 9000, the multimedia content service server 1100 further transmits or updates at least one keyword advertisement content in the keyword advertisement content area. can do.

On the other hand, when the information about the user's click on the specific keyword advertising content is received from the user computer 9000 to the meta information-based keyword advertising server 6000, 1) the keyword ad that belongs to the keyword advertising content that the click occurred A method of maintaining the content group, and 2) changing the content of the keyword ad content provided to the user, such as replacing the keyword ad content of the keyword ad content group to which the clicked keyword ad content belongs with another keyword ad content group. The policy regarding the selection of may be the content of the keyword advertising control policy. On the other hand, even if the method of 1) above is selected, if there is no click information on the other keyword ad content of the keyword ad content group belonging to the keyword ad content that has been clicked for a predetermined time, the keyword ad content of another group is replaced. The policy may be the content of the keyword ad control policy. On the other hand, when the keyword ad content group to which the clicked keyword advertising content belongs is maintained, when the click occurs on the at least one or more keyword advertising contents, the keyword advertising content in which the click is made is replaced with another keyword advertising content, or the keyword Displaying only the title of the advertisement content or placing the title-only keyword advertisement content at the bottom or in a specific position such as a corner of the keyword advertisement content area may also form the contents of the keyword advertisement control policy. Even if the keyword advertising content group of 2) is changed, the keyword advertising content selection module 6650 i) selects the next keyword advertising content group irrespective of the meta information of the keyword advertising content where the click has occurred, ii) The keyword advertisement control policy may also be selected from a method of selecting keyword advertising content having high relevance to the meta information by processing meta information of the kibcon which has clicked.

When a click on a specific keyword advertising content occurs, a user may be interested in the keyword advertising content, and thus, a click is likely to occur on other keyword advertising content that is highly related to the keyword advertising content. Therefore, the keyword advertisement content selection module 6550 distinguishes the keyword advertisement target text corresponding to the keyword advertisement content from which the user clicks, selects the keyword advertisement contents related to the differentiated keyword advertisement target text, and selects the selected keyword advertisement contents. The keyword advertisement content transmitted to the user may be updated with the keyword advertisement content. For example, the meta information-based keyword advertisement server 6000 may retrieve 10 keyword advertisement contents from the keyword advertisement content providing server 3100 by one tag for each of the two tags “refilled ink and genuine ink”. When received and sent to the user computer 9000 alternately, the keyword ad content group related to the refilled ink and the keyword ad content group related to the genuine ink in a group of three, the second group of keywords for the refilled ink When a click occurs on any one of the advertisement contents, a third group of keyword advertisement contents related to the refilled ink may be transmitted to the user computer 9000 instead of the keyword advertisement contents group related to the genuine ink. In this case, the keyword advertisement content selection module 6550 may be based on the meta information to distinguish whether the click is based on the keyword advertisement target text of the refilled ink or the keyword advertisement target text of the genuine ink from the click occurrence information. The keyword advertisement server 6000 should store the keyword advertisement target text corresponding to each keyword advertisement content. This can be handled by mapping the keyword advertisement target text ID and the keyword advertisement content ID obtained from each keyword advertisement target text.

Meanwhile, in order to know which keyword advertisement target text is related to the click occurrence information, a plurality of acquired tag or keyword advertisement target texts are transmitted to the keyword advertisement content providing server 3100 one by one for each tag or keyword advertisement target text. It is preferable to store the obtained keyword advertisement contents by mapping the tag or keyword advertisement target text. Meanwhile, even if a plurality of tags or keyword advertisement target texts are transmitted at one time, the keyword advertisement content providing server 3100 does not process each tag or keyword advertisement target text and process the keyword advertisement content for each tag or keyword advertisement target text. In the case of generating and transmitting the meta information-based keyword advertisement server 6000, the keyword advertisement content may be mapped and stored for each tag or keyword advertisement target text. In any of the methods of this paragraph, it is preferable that the meta information-based keyword advertisement server 6000 maintains the sequence information or weight information of the tag or keyword advertisement text.

The meta information-based keyword advertising server 6000 may obtain the keyword content contents information and the meta information (the keyword keyword contents obtained may include a title, an advertisement description, a linked URL or link information, an image included in an advertisement, and an advertisement. At least one of the sound included and the video included in the advertisement becomes the keyword advertisement content content information, and the ID of the keyword advertisement content in the position of the meta information-based keyword advertisement server 6000 and the meta information-based keyword advertisement server ( Various information, such as information relating to the information, etc., may be meta-information of the keyword advertisement content. Such meta-information is generally encrypted. The keyword advertisement content may further be generated and transmitted to the user computer 9000. The click-related meta information includes the keyword advertisement content ID of the meta information-based keyword advertisement server 6000 and / or click occurrence information when the user clicks on the keyword advertisement content. Information may be delivered to the. Meanwhile, the meta information-based keyword advertisement server 6000 may receive click generation information on the keyword advertisement content from the keyword advertisement content providing server 3100, which is obtained in real time or within a playing time of the multimedia content. If so, it is possible to update the keyword advertisement content provided to the user computer 9000 by using the click occurrence information. Meanwhile, the keyword advertisement content providing system 3000 first obtains the click occurrence information, and clicks on the multimedia content service system 1000 or another related system (for example, the meta information based keyword advertisement intermediation system 2000). It would be relatively desirable to convey the occurrence information. The distribution order of the click occurrence information may be an additional element of the present invention idea.

About keyword ad content selection policy in keyword ad content selection module 6650

Fourth, the keyword advertisement content selection module 6150 is keyword advertisement content selection policy information used to select at least one keyword advertisement content to be provided to the user computer 9000 at a specific time from among the plurality of keyword advertisement contents obtained. Prior to the user's click, the plurality of keyword advertisement contents are prioritized in individual keyword advertisement content units or keyword advertisement content group units by the keyword advertisement content selection policy. The policy adopted by the keyword advertisement content selection module 6550 to select the keyword advertisement content to determine the transmission priority line becomes the content of the keyword advertisement control policy. The keyword advertising content selection policy of the keyword advertising content selection module 6550 is largely based on 1) the source of the keyword ad target text, 2) the ranking of the selected keyword ad target text, 3) the expected ad revenue for the keyword ad content, 4 5) the number of keyword advertisement contents to be provided in one transmission, and 5) a change in the selection criteria of the keyword advertisement content selection module 6550 when a click occurs on a specific keyword advertisement content.

An example of such a policy is as follows. When the keyword advertisement target text occurs simultaneously in tag information and title information, the highest weight is given. When a plurality of keyword advertisement target texts exist in tag information, the keyword advertisement target text may be given a higher weight in front of the keyword advertisement target text in the order in which the keyword advertisement target texts are listed. However, if there is no keyword advertisement content for the keyword advertisement target text, the keyword advertisement target text may be excluded from the weight selection. In addition, when the expected advertising revenue for the keyword advertising content can be estimated, the estimated revenue has an important weight. In addition, when the number of keyword advertisement contents obtained through the keyword advertisement target text is smaller than the number of keyword advertisement contents to be provided in one transmission, all keyword advertisement contents may be transmitted to the user computer 9000. When a click occurs on a specific keyword ad content, the weight of the keyword ad target text related to the specific keyword ad content is increased, and the weight of the keyword ad content obtained as the keyword ad target text is increased. do. Therefore, the keyword advertisement content selection module 6550 of the meta information-based keyword advertisement server 6000 1) selects keyword advertisement content that the user is most likely to click in order to enjoy the maximum advertising revenue, and 2) probability. In general, it is necessary to select keyword advertising contents having high advertising profits, and the priority of selecting such keyword advertising contents is a weight policy. Variables affecting the expected advertising revenue may include an advertisement price of the keyword advertisement content, an expected clickthrough rate of the keyword advertisement content, and the like.

Click generation information is typically collected by the keyword advertising content providing server 3100, the keyword advertising content providing server 3100 is a multimedia content service server 1100, meta information-based keyword advertising server 6000 in real time or non-real time B may be provided to various necessary servers such as the meta information-based keyword advertisement mediation server 2100 and the meta information-based keyword advertisement providing server 4000 of the present invention. Can be provided to other servers. The module for obtaining the click generation information is called the click generation information receiving module 8900 and the module for transmitting the click occurrence information is called the click generation information transmitting module 9900.

Unit of quality

On the other hand, a combination of r keyword advertising target texts less than or equal to n and greater than 1 for n keyword advertising target text generation modules generated by the keyword advertising target text generation module 6510 (the total number of the combination is nCr). To generate the keyword ad target text combination as one query transmission unit to the keyword ad content providing server 3100, and the combined keyword ad target from the keyword ad content providing server 3100. At least one keyword advertisement content corresponding to the text may be obtained. In this case, since the keyword advertising contents are more likely to be related to all of the two or more combined keyword advertisement target texts, the likelihood of inducing a user's click is higher. In this case, the combination generation may be performed only with the keyword advertisement target text generated from the plurality of tag information. In this case, the combination generation may be preferentially generated as a plurality of tags appearing in front of the plurality of tags.

Keyword Ads Display Module (7900)

Next, the keyword advertisement display module 7900 of the present invention will be described. The keyword advertisement display module 7900 may include at least one selected by the keyword advertisement content selection module 6550 with reference to a keyword advertisement control policy DB 6540 for the at least one keyword advertisement content obtained corresponding to the selected multimedia content. The selected keyword advertisement contents may be displayed on a predetermined portion of the screen of the user computer 9000 provided with the multimedia contents. Preferably, the predetermined part is a lower part of the multimedia content, and the keyword advertisement content display area 100 is an example. The keyword advertisement display module 7900 delivers the always-selected keyword advertisement content to the multimedia content service server 1100 so that the multimedia content service server 1100 generates a web page together with the selected multimedia content. The web page data is transmitted to the user computer 9000. Meanwhile, the multimedia content service server 1100 generates a web page using only the selected multimedia content while specifying an area 100 in which the selected keyword advertisement content is to be displayed on the user computer 9000, and uses the web page. The selected keyword advertisement contents may be transmitted to the computer 9000, and a browser or the like installed in the user computer 9000 may receive the selected keyword advertisement contents data and display the selected keyword advertisement contents in the region 100 to be displayed. In the meantime, the multimedia content service server 1100 allows a specific program 9100 to be installed in the user computer 9000 by a plug-in method, and the plug-in program 9100 displays a predetermined keyword advertisement content 100. Also, data related to the selected keyword advertisement content may be received from the keyword advertisement display module and displayed. That is, the keyword advertisement display module 7900 transmits the selected keyword advertisement contents to the outside of the user so that the selected keyword advertisement contents can be displayed on the user computer 9000. The transmission of the selected keyword advertisement content through the keyword advertisement display module 7900 is 1) transmitted to the multimedia content service server 1100, and the multimedia content service server 1100 is transmitted to the user computer 9000. Or 2) a method of directly transmitting to the user computer 9000 to be displayed in the preset area 100 installed in the user computer 9000.

On the other hand, the keyword advertising display module 7900, when the keyword advertising content is clicked on the transmitted keyword advertising content, a code for displaying a screen for displaying the advertising content of the advertiser connected to the keyword advertising content in a predetermined position You can also insert The code may include corner coordinate information of the screen to be displayed, or may always be displayed on the screen. This may be especially useful for user computers with large screens, such as IPTV. On the other hand, the multimedia content service system 1000 inserts an event detection function into a code such as Javascript in information such as a web page transmitted to the user computer 9000, the event detection function from the user computer 9000 Upon receiving selection information such as a click on the keyword advertising content, 1) placing the screen of the web page on which the video is displayed at the top left or bottom right of the display device of the user computer 9000, or 2) Temporarily hides all information except the video play area on the displayed webpage screen and restores it when the user receives the selection information on the webpage screen on which the video is displayed again; or 3) The webpage screen ( Will be the screen displayed on the IPTV. It can be adjusted so that it is small and displayed at the top left or bottom right. On the other hand, when any one or more of 1) to 3) is executed, the advertisement content of the advertiser may be set in advance so as to be placed farthest from the web page. Of course, if there is a click on the keyword advertisement content after the video is finished playing, the advertiser's advertisement content (the advertiser's specific screen or the information for the advertiser to present is the advertisement content of the advertiser on the screen where the video is displayed). Below, same as above).

On the other hand, if the keyword advertising content providing server 3100 does not provide information for estimating keyword advertising revenue for the selected keyword target text, such as an advertisement price and / or an estimated clickthrough rate, for the keyword target text. Even if the keyword advertisement content selection module 6650 selects the keyword advertisement content rationally with reference to the keyword advertisement control policy, the keyword advertisement content having a relatively low advertisement effect may be selected. On the other hand, when there are many keyword advertisement target texts generated by the keyword advertisement target text generation module 6510, and transmits all the keyword advertisement target texts to the keyword advertisement content providing server 3100, the keyword advertisement content providing server. Unnecessary load may be given to the 3100. Therefore, the keyword advertisement target text generation module 6510 needs to filter on the firstly generated keyword advertisement target text, and the keyword advertisement target text is generated only for the secondly generated keyword advertisement target text that has passed a predetermined criterion. The corresponding keyword advertisement content may be obtained by transmitting to the content providing server 3100.

Filtering Module (6560)

The meta information-based keyword advertisement server 6000 may perform filtering before transmitting the keyword advertisement target text to the keyword advertisement content providing server 3100. The reason for filtering is that if there is a large number of keyword-targeted text, there is no guarantee that all keyword-targeted text will have keyword advertising content, or that there is no guarantee that it will generate ad revenue. It is to extract the text or to select the text of the keyword advertisement that has the potential to contribute more to the advertising revenue. In the filtering, the filtering module 6560 of the present invention inquires the keyword advertisement target text with respect to the keyword advertisement target text to the advertisement keyword DB 6704, and registers with the advertisement keyword DB 6704, or is preset. This is achieved by extracting the keyword advertisement target text that satisfies the condition. The preset condition exists in the keyword advertisement control policy DB 6540, and the inquiry about the preset condition is performed by the filtering module 6560 inquiring the keyword advertisement control policy DB 6540. In this case, only the keyword advertisement target text that has passed through the filtering module 6560 is sent to the keyword advertisement content providing server 3100.

As the contents of the advertisement keyword DB 6657, 1) name data of a product or name data of a service, 2) registered in the keyword advertisement content providing server 3100, and are obtained from the keyword advertisement content providing server 3100. Advertisement keyword list of the received advertisers, 3) can be a keyword advertising target text verified generation of advertising revenue through the implementation of the present invention, or 4) self-generated, or a list of advertising keywords obtained from a third party. The name data of the product or the name data of the service of 1) means the name of the product or the name of the service, the name of the supplier who provides the product or service to others (e.g., Hyundai E & C), or the text of the marked content such as a trademark in text. Transliteration of the character portion (e.g., the character portion of the trademark content, such as trademarks incorporating symbols, figures, three-dimensional shapes and colors, including letters), and the sound portion of the trademark content, such as trademarks When transliteration of the contents of the mark, such as the corresponding letter of the company and trademark in a foreign language, in the native language (in case of IBM, such as IBM, separate transliteration occurs when the native language is different. Example: McDonald means McDonald's, McDonald's, etc.). The keyword list of advertisements of 2) or 4) refers to a keyword for advertisement registered by advertisers in order for advertisers to search their advertisement. For example, when a user enters the advertisement keyword as a search input form at www.google.com or www.naver.com, not only the search result for the search input form but also the advertisement contents of advertisers associated with the advertisement keyword are output. Therefore, the list of advertisement keywords registered by the advertisers may be of course stored in the keyword advertisement content providing server 3100, and some or all of them may be available. The above 3) is accumulated over time through the implementation of the present invention, a collection of the keyword ad target text associated with the keyword ad content generated by the actual click, etc. of the keyword ad content exposed to users to generate advertising revenue Say. 4) is equivalent in content to 2) above, but differs only in the subject.

A plurality of meta information may be stored together in the advertisement keywords registered in the advertisement keyword DB 6657 and / or the keyword advertisement content providing server-side advertisement keyword DB 3140, and the meta information may be updated. have. The meta information stored in correspondence with the advertising keywords may include 1) total impressions / total calls, 2) total impressions / total calls, and / or increase rates of the advertising keywords during or during a predetermined period. Total advertisers, 4) average advertising price, 5) highest advertising price, 6) minimum advertising price, 7) average advertisers, 8) average keyword ad content, 9) average advertiser growth, 10) average advertising price 11) impressions, 12) click-through rate for relevant keyword ad content relative to impressions, 13) total clicks, 14) ad revenue generated, 15) Increase / decrease rate of impressions, 16) increase / decrease rate of click-to-impression rate, 17) increase / decrease rate of total clicks, 18) increase / decrease rate of ad revenue generated. When the filtering module filters the keyword advertisement target text, the related keyword advertisement control policy may require that any one or more of 1) to 18) satisfy a preset numerical value range.

The keyword advertisement control policy includes policy information on how much to use the keyword advertisement target text under which condition for n keyword advertisement target texts. The keyword advertisement target text filtering condition may be a degree of satisfaction with a criterion for any one or more selected from 1) to 18) for the keyword advertisement target text. For example, when determining whether to select "refill ink" as the text for keyword advertising, the frequency of the entire document for "refill ink" is three or more times, and 3) is 5 or more, and 6) It can be judged whether or not the condition of 200 won or more is satisfied.

A more sophisticated embodiment of determining whether to generate keyword advertisement target text with respect to the keyword advertisement target texts will be described. A difference function for each condition may be introduced for each criterion. For example, the difference function of the frequency may be dif_frequency = the frequency of the keyword target text i-the reference frequency, and the difference function for various conditions j such as 1) to 18) above is dif_Condition_j = the keyword target text i. Can be a condition value-reference condition value. The frequency may be more useful when the keyword advertisement target text is due to the description information. Meanwhile, even when only the title and the tag are considered, the keyword advertisement target text simultaneously appearing in both may be important keyword advertisement target text.

In this case, the score function for the keyword i target text i may be, for example, the sum of {F (difference function) * weight for each difference function}. At this time, if one of the above 1) to 18) is not used, the weight should be 0, and F (x) may be equal to x or x ^ 2. (X is an input variable of F, x becomes the difference function.)

In this case, at least one keyword advertisement target text having the highest score function value may be selected as keyword advertisement target text for each keyword advertisement target text i. Meanwhile, other kinds of functions may be introduced that utilize various available variable values for the keyword target text other than the difference function, and other conditions other than the frequency or 1) to 18) may be introduced. In addition, the weight may also vary according to the weight policy of the keyword advertisement control policy DB 6540, and it will be apparent to those skilled in the art that the formula constituting F (x) may also vary.

On the other hand, the communication module of the present invention serves to transmit and receive data inside or outside. It will be apparent to those skilled in the art that such communication module may be included in each functional module of the present invention and may be included in a server or a system unit.

The network 8000 refers to any communication means that enables a computer to transmit and receive data by connecting a computer such as a wired or wireless network 8000 or the like.

In the present invention, the computer is a mobile computer terminal that supports voice / data communication, such as a personal computer such as a PC or a laptop, a portable computer, a server, a mobile phone, a game machine including a wired / wireless data communication function, an interactive TV such as an IPTV, It is possible to receive wired / wireless communication and receive multimedia contents and provide multimedia contents information to users, such as display devices, PDAs, portable media players (PMPs) or MP3 / MP4 players that are attached to main products such as home appliances. Any device that includes a CPU and a meta information acquisition module 5100.

Generate keyword ad target text

The foregoing description of the inventive concept focuses on providing the user computer 9000 with keyword advertising content based on meta information additionally included in the multimedia content. Meanwhile, the inventive concept of the present invention obtains text information related to the multimedia content, generates a keyword advertisement target text based on the text information, and uses the keyword advertisement contents based on the generated keyword advertisement target text. It can be extended to provide to the computer 9000. Therefore, the key idea of the present invention is gathered in a method of obtaining text information from the multimedia content itself or information related to the multimedia content, and generating the keyword advertisement target text.

Hereinafter, the text acquisition module 3110 and the keyword advertisement target text generation module 6510 that obtain text from the multimedia content itself or information related to the multimedia content will be described in more detail. For convenience of description, the text acquisition module 3110 will be described. ) And the keyword advertisement target text generation module 6510 will be described on the assumption of a non-weighting model such as that performed in the meta information-based keyword advertisement server 6000. It is obvious that the same applies to the central model.

Non-tag Text Get Module (5130)

The text acquisition module 3110 directly or indirectly obtains text information other than a tag from the multimedia content. The multimedia contents handled by the present invention generally include 1) moving images, 2) images, and 3) sounds. A video mainly refers to a video file such as a UCC video, a user generated contents (UGC), a user modified contents (UMC), or a PCC video. The video includes a photo, and at a time that can be subsumed into a category called an image. Refers to an image file that can be recognized by the sound, and refers to a sound file that can be recognized by hearing, such as music, sound, song, effect sound, and the like. The reproduction of the image refers to reading and displaying an image file on the user's computer 9000 to visually recognize the image. The reproduction of the image shows that an image specific to the user's computer 9000 is visually recognized. Say while losing. Hereinafter, the present disclosure will be described based on a moving picture, and if it is specialized only in an image or a sound, it will be described separately.

The multimedia content provided by the multimedia content service system 1000 typically includes title and / or at least one tag information, and often includes descriptive information. In this case, the tag information is often in the form of nouns, usually in the case of one noun or a compound noun, and sometimes two or more nouns or a compound noun form one tag. In this case, since the tag is usually composed of nouns, if the tag information is a noun, it is not necessary to pass the morpheme analyzer. The morphological analyzer will be described later in detail. Therefore, the text included in the tag information becomes, in principle, the target text of the advertisement. In addition, since the names of classifications or categories are also nouns in most cases, this can also be handled with tag information.

On the other hand, in the case of the title, it is necessary to pass the stemmer. This is because in the case of titles, parts of speech other than nouns are often present in order to form a semantic unit. In particular, unlike the description information, the title is selected by the creator of the multimedia content as the best representation of the multimedia content, and thus, the nouns extracted from the title can be usefully used as the advertisement target text.

In addition, since the description information of the multimedia content is often in the form of sentences or phrases, it is preferable to extract the nouns through the morpheme analyzer. On the other hand, there may be text information generated by the multimedia content service system 1000 through voice recognition for the multimedia content, and such information is also preferably passed through a morpheme analyzer to extract nouns.

Non-Text Information Get Module 5120

The non-text acquisition module 5120 may obtain text information through speech recognition on the speech data included in the multimedia content, in addition to obtaining the information in the form of text. Speech recognition may be achieved by playing the multimedia content. The quality of the speech recognition may not be important, since the keyword advertisement target text may use an advertisement keyword DB 6657 or the like as a filter. As will be described in detail below, even if a large number of wrong speech recognitions are shown, the texts corresponding to the recognized speech may be treated as the keyword advertisement target text only for the text shown in the advertisement keyword DB 6657.

Keyword Ad Target Text Generation Module (6510)

Next, the structure and function of the keyword advertisement target text generation module 6510 that generates the keyword advertisement target text from the text obtained by the text acquisition module 3110 will be described. The keyword advertisement target text generation module 6510 generates keyword advertisement target text. The method of generating the keyword advertisement target text includes a method of generating from tag information and a method of generating from title or description information.

The first type is a method in which the keyword advertisement target text generation module 6510 generates keyword advertisement target text using only tag information. In this case, since the tag information is mainly a noun, all the acquired tag information can be treated as the keyword advertisement target text as it is, or only the tag information passing through the predetermined filter can be treated as the keyword advertisement target text. In this case, the predetermined filter may be a product service name DB that collects a name of a product or service, and the product service name DB may form a content of the advertisement keyword DB 6657 of the present invention. That is, the keyword advertisement target text generation module 6510 receives all tag information included in meta information of the specific multimedia content from the text acquisition module 3110, and then inquires the tag information in the product service name DB. Next, only the tags existing in the product service name DB may be taken and generated as keyword advertisement target text. In this case, the preset filter may be an advertiser registration advertisement keyword DB registered by an advertiser or another third party provided by the keyword advertisement content providing server 3100, and the advertiser registration advertisement keyword DB may be the advertisement keyword DB of the present invention. 6570). The advertiser registered advertisement keyword DB stores an advertisement keyword registered by the advertiser in order to advertise his or her product or service. The keyword for advertisement may be an advertisement title and / or advertisement description. In this case, the keyword advertisement target text generation module 6510 receives all tag information included in the meta information of the specific multimedia content from the text acquisition module 3110, and then transmits the tag information to the keyword advertisement content providing server. After querying the advertiser-registered advertisement keyword DB provided by 3100, only the tag existing in the advertiser-registered advertisement keyword DB may be taken and generated as the keyword advertisement target text.

The second type is that the keyword advertisement target text generation module 6510 generates the keyword advertisement target text even in the title information and / or the description information. In this case, the text acquisition module 3110 obtains text from title information and / or description information of the multimedia content and passes the morpheme analyzer to extract nouns. In this case, in particular, in the case of nouns derived from title information, weights may be treated particularly, and in the case of nouns derived from descriptive information, the weights may be kept low. In this case, when there is auto tagging information from the description information, the auto tagged tag may be used. Auto-tagging refers to automatically generating tag information that can represent a string by passing through a stemmer and other preset filters when there are strings such as phrases, clauses, sentences, and paragraphs. The passing filter may be an advertisement keyword DB 6657. In this case, only the nouns passed by passing the obtained nouns through the at least one predetermined filter may be treated as the keyword advertisement target text.

The keyword advertisement target text generation module 6610 of the present invention may be composed of a keyword advertisement target text preprocessing engine, a keyword advertisement target text extraction engine, and an advertisement keyword DB 6657. When preprocessing such as morphological analysis is required for the obtained text, the keyword advertisement target text preprocessing engine performs preprocessing. If the obtained text is due to tag information, the text preprocessing engine may be skipped. The keyword advertisement target text extraction engine searches and filters the received text (including the preprocessed text) into the advertisement keyword DB 6657 to extract a text string existing in and matched with the advertisement keyword DB 6657, A keyword advertisement target text is generated from the extracted text string. The advertisement keyword DB 6657 may be, for example, a product service name DB that collects the names of products or services, or an advertiser registered advertisement keyword DB provided from the keyword advertisement content providing server 3100.

The keyword advertisement target text is text in a form that can be accommodated by the keyword advertisement content providing server 3100. There are three examples.

The first is the name of the product or service. It is preferable that the name of the product or service has a form such as a noun or a noun phrase. For example, iPods, notebooks, flower delivery, and the like are examples of these.

Second, when the keyword advertisement content providing server 3100 registers a search keyword advertisement (the advertiser registers a specific keyword and the searcher inputs the keyword or a keyword related to the keyword), the search result including the keyword advertisement content is included. Ad format that performs the way the advertiser's keyword ad content is displayed, such as search keyword ads performed on google.com, and the same method of search keyword advertising performed by overture.com. And a variety of search keyword advertising products.) May be "search advertisement keywords" registered by search keyword advertisers. The search advertising keywords may be registered by an advertiser, and may be keyword advertising content including an advertisement title, an advertisement description, and / or other text. Examples of the search advertisement keyword may include a brand (trademark) such as "prada", a name of the product or service, various common nouns such as a place name or a person name, a proper noun, and the like. It can be any string you set.

Third is string information such as phrases, clauses, and sentences. Many search portals, such as google.com and naver.com, or search keyword ad agencies such as overture.com, process the input string information and register their search results with keyword ad content, It has the ability to provide search results containing keyword advertising content that matches or is related to search advertising keywords. Therefore, in order to provide a search result including the keyword advertisement content in the obtained text, the keyword advertisement target text generation module 6610 processes the text into predetermined units (sentence or phrase unit) to convert the keyword advertisement target text. Extract.

Next, the keyword advertising target text generation module 6510 extracts the keyword advertising target text in more detail.

The method for extracting the keyword advertisement target text by the multimedia content service system 1000 of the present invention includes: 1) having the advertisement keyword DB 6657 having the keyword advertisement target text stored therein as a DB, and obtaining the received text from the keyword. A method of extracting the keyword advertisement target text by querying the advertisement target text in a DB; 2) extracting the keyword advertisement target text by transmitting the obtained text to a predetermined intermediary server and processing the obtained text to the intermediary server; The multimedia content service system 1000 may be transmitted or the like.

The advertisement keyword DB 6657 may include a name of the product or service, or a "search advertisement keyword" registered by the advertisers. In this case, the intermediary server may extract the keyword advertisement target text through a third server having the advertisement keyword DB 6657 or the advertisement keyword DB 6657. Prior to querying the advertising keyword DB 6657 with the obtained text, the obtained text may be preprocessed, wherein the preprocessing is to perform parsing or morphological analysis (including complex noun decomposition). Say. The preprocessing is performed by the keyword advertisement target text preprocessing engine.

If the obtained text is about nouns or noun phrases, it is an easy task to query the advertisement keyword DB 6657. (When using a stem analyzer in English, it is simple to treat a plural form of a noun as a singular form.) However, when using a survey such as Korean, it may be necessary to separate the survey through the morphological analysis. In addition, in the case of a verb or the like, extracting a noun related to the verb may be performed through morpheme analysis or the like. (For example, it refers to separating "travel" from "going.") It is well known in natural language processing technology to extract nouns from the text obtained through the above parsing and morphological analysis. Omit. Such preprocessing is processed where the advertisement keyword DB 6050 is included. That is, if the multimedia content service system 1000 has the advertisement keyword DB 6657, the keyword advertisement target text (product, service name, proper noun, Common nouns, search advertisement keywords, etc.), and the same is true of the intermediary server and the third server.

Of course, although the multimedia content service system 1000 has been expressed in terms of expression such as the keyword advertisement target text extraction, the function is performed by any program 9100 performed in conjunction with the multimedia content service system 1000. It does not exclude that. That is, the relationship between the module performing the function of acquiring and / or extracting the keyword advertisement target text and the multimedia content service system 1000 is all included in 1) the same entire program 9100 operated by the same operator. 2) When the same operator is operated but operates as a separate program (9100), 3) When a separate program (9100) operated by a separate operator or cooperates by performing communication between the two (multimedia content service system The multimedia content service system 1000 has a control over the multimedia content file that 1000 plays and provides by streaming, and includes providing the module with information obtained from a file controlled by the multimedia content. There is.

At this time, the problem of speech recognition will be described briefly. The present invention extracts the keyword advertising target text from the text (tag information, title information, description information, category information, etc.) obtained from the user's audio-visual multimedia content, and (advertisement) keyword advertising with respect to the extracted keyword advertising target text. The purpose is to display the search results containing the content to the user. When voices from multimedia content say "New York 5th Street Fashion Magazine Editors Prada Bags", speech recognition is not complete, so "Fashion" is "Person" and "Magazine" is "Narrow". However, suppose that "Prada" is normally recognized as "Prada" as a bag. In this case, if "Person" and "Narrow" are not present in the advertisement keyword DB 6050, the "Person" and the " Narrow "may be excluded from the keyword advertisement target text, and if at least one of" Prada "or" bag "is present in the advertisement keyword DB 6657, only what is present may be treated as keyword advertisement target text. That is, even if the speech recognition system does not recognize the misrecognition, only those in the ad keyword DB 6657 are processed as the keyword ad target text among those that have been recognized. In this situation, there is no necessity to provide search results containing the keyword advertising contents for all of the "fashion", "magazine", "prada", and "bag", so it is correctly recognized (for example, the advertisement keyword DB ( 6570) will provide users with search results that contain keyword ad content only, so that users will not be surprised at all. In addition, there is an additional advantage in that the speech recognition rate is perceived as being quite high, ie, in this situation, the user may receive search results including (advertising) keyword advertising content for "Prada" and / or "bag." Of course, the keyword ad content providing server 3100 exists in the advertisement keyword DB 6657. In some cases, we may not be able to provide search results containing keyword ad content, in which case search results containing keyword ad content are normally available, except that we may not be able to provide search results containing the keyword ad content. Will only be exposed to the user.

If you only expose search results that contain non-advertising keyword ad content, this issue is very unlikely. However, if you need to expose search results that contain ad keyword advertising content, you may not register your ad as a search keyword ad. Search terms may occur. In this case, there may be a method of exposing a search result including the non-advertising keyword advertisement content according to the policy, or a method of exposing only the search result containing the advertised keyword advertisement content normally obtained, but the latter is preferable. This problem is attributed to a processing problem when a plurality of keyword advertisement target texts described later are not registered as a search keyword advertisement or when there is no advertisement for the keyword advertisement target text. When there are a plurality of texts to be advertised, if they are transmitted one by one to the keyword advertising content providing server 3100, there is an advertisement for the i-1st keyword advertising target text and an advertisement for the ith keyword advertising target text. Otherwise, keyword ad content for the i th keyword ad text is not available, so skip processing for the i th keyword ad text and skip the keyword ad content for the i-1 th ad text. It continuously maintains or performs a predetermined process, and transmits the i + 1th keyword advertisement target text to the keyword advertisement content providing server 3100. If the plurality of keyword advertisement target texts are divided into several groups and transmitted to the keyword advertisement content providing server 3100, the i-th and i-th processes described in this paragraph may be performed in groups. If a plurality of keyword advertisement target texts are simultaneously transmitted to the keyword advertisement content providing server 3100, if there is keyword advertisement content transmitted from the keyword advertisement content providing server 3100, the received keyword advertisement content is numbered once. It will be able to roll and provide the keyword ad content received in all or several units at. For example, when the multimedia content service providing system receives 10 keyword advertisement contents from the keyword advertisement content providing server 3100, when two keywords are processed, the multimedia content service providing system generates a set of two different keywords five times. The set of advertisement contents may be transmitted to the user computer 9000.

The advertisement keyword DB 6657 may include a name of the product or service, or a search advertisement keyword for a search keyword advertisement registered by the advertisers. The generation method and the updating method of the advertisement keyword DB 6657 will be described together.

The name of the goods or services is a set of goods such as a product dictionary, a service name dictionary, a job name dictionary, a product electronic catalog (with international standards), a service electronic catalog, or a noun dictionary, and the like. name or / and service name) (of course, can be transmitted from an external third party), and the name set of the product or service can be stored in the DB. Of course, the name set of the product or service can be indexed so that the DBMS or search engine can search. The search advertisement keyword set that collects the search advertisement keywords may be a portal that performs the search keyword advertisement (for example, google.com, naver.com, etc.) or a search keyword such as overture.com. It may be generated by receiving from the advertising agency). That is, the server of the person who executes the search keyword advertisement and the multimedia content service system 1000 communicate with each other at periodic or predetermined time / condition units to obtain the search advertisement keyword set from the server of the person who performs the search keyword advertisement. It may be obtained, and the advertisement keyword DB 6657 may be generated and updated (updated) with the obtained search advertisement keyword set. Of course, the search advertising keyword set may come from a mediation server that performs a mediation function between the multimedia content service system 1000 and the keyword advertising content providing server 3100.

If the multimedia content service system 1000 does not have the advertisement keyword DB 6657 or if the advertisement keyword DB 6050 is not rich enough to perform its function (a significant amount of text has been obtained, but the advertisement In the case where the keyword DB target text does not generate any one of the keyword advertisement target texts), the third method described above may be applied. The third method transmits string information such as phrases, clauses, and sentences to a plurality of search portals such as google.com, naver.com, or a search keyword advertisement agency such as overture.com. Agencies analyze the strings (including parsing, morphological analysis, etc.), and most portals accept textual input in any form, such as sentences, phrases, or phrases, and from them, keyword advertising content in any form. The search result including the keyword advertisement target text and / or keyword advertisement content corresponding to the keyword advertisement target text. To the system 1000. When only the keyword advertisement target text is transmitted, the multimedia content service system 1000 transmits the same to the keyword advertisement content providing server 3100 to receive a search result including the keyword advertisement content. When an embedded search result is sent, it is displayed to the user. Of course, a mediation server may be mediated between the multimedia content service system 1000 and the search portal or the search keyword advertisement agency server. Since the multimedia content service system 1000 and the search portal or the search keyword advertisement agency server perform and exchange information and respective functions will be apparent to those skilled in the art when introducing a mediation server, a detailed description thereof will be omitted. .

A method of transmitting the keyword advertisement target text to the at least one keyword advertisement content providing server 3100 capable of providing a search result including the keyword advertisement content will be described. When the text is obtained from the multimedia content, when the text is obtained through 1) subtitles (captions) or 2) translated subtitles and / or 3) speech recognition, unlike the UCC tag, streaming of multimedia content is transmitted. (Of course, it is possible to play the multimedia content in advance to perform voice recognition, or to play the multimedia content during streaming transmission to perform the voice recognition). The system 1000 may include 1) a predetermined time or / and 2) a predetermined number of keyword advertised text units (e.g., no new keyword advertised text is transmitted until there are three or more). The advertisement target text may be transmitted to the keyword advertisement content providing server 3100. On the other hand, when obtained from the UCC tag information, the temporal transmission of the multimedia content and the acquisition of text from the UCC tag information are independent (ie, independent of each other, that is, the text obtained from a specific section of the multimedia content and the UCC tag). Is irrelevant), extracting the keyword advertisement target text from the text obtained from the UCC tag and transmitting it to the keyword advertisement content providing server 3100 may be performed independently of the transmission of a specific section of the multimedia content. . Preferably, the keyword advertisement target text is extracted in the manner of 1), 2), and / or 3) during the start of the multimedia content, the end of the multimedia content, and / or the transmission of the multimedia content. Sections that fall short of the set number (there may be a place where it is difficult to extract text because there are few voices or subtitles in a certain section during multimedia content transmission. May be transmitted to the keyword advertisement content providing server 3100. The keyword advertisement target text obtained from the UCC tag may be transmitted to the keyword advertisement content providing server 3100. On the other hand, if the method of 1) to 3) is not possible, text may be extracted from tag information, title information, description information, and the like.

Next, the keyword advertisement content providing server 3100 that generates a search result including the advertisement keyword keyword contents for the keyword advertisement target text will be described. In an embodiment, the keyword advertisement content providing server 3100 may include a search word acquisition unit that receives a search word (query) that is transmitted from the outside, a search word processing unit that processes a search word obtained by the search word acquisition unit, and the search word acquisition unit obtained by the keyword advertising content providing server 3100. The search term or the search term processing unit may include an advertisement search engine that performs a search and a search result transmission unit which transmits a search result. The search word processing unit may be optional, but is preferably present. In particular, the keyword advertising target text generation module 6510 in the present invention, even if the processing is required for the keyword advertising target text generated. This is because the search keyword advertisement itself included in the keyword advertisement content providing server 3100 and the phrase input by the user are often different from each other, and this is a keyword generated by the keyword advertisement target text generation module 6510 of the present invention. The same applies to the text to be advertised. The advertisement search engine unit may further include an advertisement search unit which directly performs a search, an advertisement search index or a keyword advertisement content DB which is an object of which the advertisement search unit queries by a search query. In this case, when searching by a search engine method, a method of finding the existence and location of specific keyword advertising content in the keyword advertising content DB is performed through the search index for advertising. Meanwhile, a method of directly querying the keyword advertisement content DB through a DB query using a DBMS (Database Management System) or other method may be introduced. In this case, at least one or more specific fields in the keyword advertisement content DB may be used to increase a query response speed. May be indexed. In this case, the keyword advertisement content DB may be logically present inside the keyword advertisement content providing server 3100 but outside of the advertisement search engine unit. In addition, the keyword advertisement content providing server 3100 may further include an advertisement evaluation unit that evaluates each advertisement or the respective keyword advertisement contents. How the advertisement evaluator evaluates an advertisement is one embodiment of the advertisement evaluation method for "Prada" and "bag".

Search result transmission unit When the keyword advertisement target text is transmitted to at least one keyword advertisement content providing server 3100 capable of providing a search result including keyword advertisement content, the keyword advertisement content providing server 3100 transmits the text. A search is performed on the received keyword advertisement target text to generate a search result including the keyword advertisement content. In this case, the search result including the keyword advertising content generated by the keyword advertising content providing server 3100 does not exclude a search result including the non-advertising keyword advertising content, but is a search result including the advertising keyword advertising content. More preferably, the search result including the advertising keyword advertising content may be search keyword advertising content of the advertiser corresponding to the search keyword registered by the advertiser. The search keyword advertisement content of the advertiser may be in the same text as a search advertisement of google.com, but may be a non-text image advertisement (non-text advertisement such as a banner, multimedia content, or a flash file). This is because, when the advertiser associates the search keyword with respect to the non-text type keyword advertisement content, the non-text type keyword advertisement content corresponding to the search keyword can be extracted.

In the above example, when "Prada" and "bag" are transmitted to the keyword advertising content providing server 3100, the keyword advertising content providing server 3100 is the advertising keyword advertising for the "Prada" and the "bag". The search result including the content may be generated. In general, the search result including the advertising keyword advertising content may be an advertiser's keyword advertising content with the advertiser paying a predetermined fee for the “prada” and the “bag”. When a searcher enters the word "prada" or "bag" as a search term, the advertiser is exposed to the keyword advertising content such as exposure of the keyword content or post-impression click. Search keyword advertising is performed by paying for the exposure of a specific website or web page linked to the advertisement content.

In this case, the following four problems may occur from the viewpoint of the keyword advertisement content providing server 3100. First, the search result including the advertising keyword advertising content of the keyword advertising content providing server 3100 may be at least two. In this case, whether to transmit everything to the multimedia content service system 1000 or only a specific number is transmitted to the multimedia content service system 1000. That is, it is a problem regarding the number of keyword advertisement contents transmitted. Second, when it is necessary to provide search results including keyword advertising contents for the "Prada" and the "bag" at the same time, how much of the search results including the keyword advertising contents will be provided. In other words, it is a matter of distribution to multiple requests. In more detail, when the search result providing request including the keyword advertising content for the "Prada" and the "bag" from the multimedia content service system 1000 is requested at the same time (or at the same time within a preset time zone), If a search result including the keyword advertising content is replaced in the multimedia content service system 1000, it may be a real time replacement, but may be replaced at a minimum predetermined time interval. Which one should first provide a search result that includes the keyword advertising content, and 2) determine how many search results containing the keyword advertising content should be provided for each.

Methods for solving the first and second problems are exemplary and may be as follows. First, the multimedia content service system 1000 sets the number of search results including the keyword advertisement content requested by the multimedia content service system 1000 as a limit condition so as not to exceed the limit condition. Of course, the keyword advertisement content providing server 3100 may transmit the number of search results including the keyword advertisement content preset in its usual manner without considering the limitation condition, and the multimedia content service system 1000 may The number of exposures to the user of the search result including the keyword advertisement content transmitted from the user's point of view may be adjusted.

The keyword advertisement content providing server 3100 may be configured to: 1) display at least one or more of each advertiser's keyword advertisement content and / or click-to-advertisement price, and 2) the keyword advertisement content may be exposed for each of the obtained keyword advertisement target texts. You may know your clickthrough rate versus impressions. Therefore, in the position of the keyword advertising content providing server 3100, the method of increasing the maximum advertising revenue will be in the order of higher advertising price when only 1) is applied, and when 1) and 2) are simultaneously applied, respectively. Advertisement cost per click * Advertisement click-through rate will be an estimate of the expenditure advertising cost when paying for an ad. Therefore, the keyword advertisement content providing server 3100 calculates an expected value of the advertisement cost for each search advertisement keyword with respect to at least one or more keyword advertisement target texts that are transmitted, and 1) each search advertisement for each of the high ranks. For each keyword, 2) a search result including keyword advertisement content for two or more search advertisement keywords may be mixed to generate a search result including keyword advertisement content to be transmitted to the multimedia content service system 1000. Of course, when transmitting the keyword advertising content of each advertiser to the multimedia content service system 1000, information about the advertising unit price of each keyword advertising content and / or click-through rate of each keyword advertising content is transmitted together, and the multimedia content The service system 1000 may determine whether each keyword advertisement content is exposed, an exposure ranking, an exposure time, and the like, and expose the keyword advertisement content to the user. The keyword advertisement target text is received from the mediation server (multimedia content service system 1000), the keyword advertisement target text is processed, an advertisement search is performed on the processed keyword advertisement target text, and the keyword advertisement of keyword advertisement content is received. The content may be evaluated, the ranking information may be assigned to the evaluated keyword advertisement content, and the keyword advertisement content may be transmitted to the mediation server (the multimedia content service system 1000). In this case, the processing of the keyword advertisement target text may be omitted. The processing of the search object means that if the keyword advertisement target text is not a noun such as a product or service name or any other character string that can be easily accommodated by the advertisement search server, 1) the advertisement search server easily accepts it. Or 2) replace the relevant character string with a relevant string that is not included or matched in the keyword advertisement target text, so that the search can be performed with the character string. In one embodiment of the processing, if the word "expected to be very hot today" is obtained as the keyword ad text, the text "very hot" is processed in this sentence, and the processed ice cream or the like is processed. For example, generating text. The specific processing of such a keyword can be employed in a large number of research results of natural language processing.

For example, it is as follows. The keyword advertisement target text / search advertisement keyword is "prada" and "bag". This is an exemplary model, it will be readily applicable to those skilled in the art when the number is different from the present example.

Keyword ad text / search ad keywords Advertiser Ad unit price (USD) % CTR Expected Value (USD) Prada A 5 20 1.0 Prada B 4 10 0.4 Prada C 3 40 1.2 Prada D 2 15 0.3 bag E 3 30 0.6 bag F 2 20 0.4 bag G One 30 0.3 bag H 0.5 20 0.1 Prada bags I 10 10 1.0 Prada bags J 7 20 1.4 Prada bags K 5 20 1.0 Prada bags L 3 25 0.75

In the above case, if the keyword / target advertising text / search keyword is "Prada", it is most desirable to first expose the keyword advertising content of the advertiser C high expectations. If you need to expose two, C and A might be the right choice. Of course, if the advertisement price is to be exposed first according to the advertisement exposure policy of the keyword advertisement content providing server 3100, A, B, C, D will be exposed in order.

If you have a mixture of Prada and bags in parallel, and the number is three, it would be reasonable to expose advertisers C, A, and E. In other words, exposing keyword advertising content above advertiser E for "bag" would be a more reasonable choice than exposing B keyword advertising content for "Prada".

If there are advertisers for "Prada bag," it would be desirable to first expose the keyword advertising content of advertiser J when the keyword ad text / search ad keywords are "Prada" and "bag." In this case, when one of the advertisers A, I, and K having the same expected value should be included, an internally selected policy (I and K in which two search ad keywords generally match is preferable. Exposing a high I can be a policy), or circular exposure. (Other systems having information such as advertisement price, click-to-impression ratio, etc. for the "Prada", "bag", and "Prada bag" keywords (multimedia content service system 1000 or meta-information-based keyword advertising mediation system ( 2000) may also select an optimal keyword, such as the keyword advertising content providing system 3000.)

Of course, at this time, the multimedia content service system 1000 determines whether or not the exposure is provided, and provides the keyword advertisement target text / search advertisement keyword to two or more keyword advertisement content providing servers 3100, and the keyword advertisement content is If the share of the advertising costs (share) according to the impression of the included search results or clicks on the search results containing the exposed keyword advertising content, and each keyword advertising content providing server 3100 has a different revenue share ratio, The multimedia content service system 1000 may select to expose an advertisement of an advertiser having the highest expected value based on the multimedia content service system 1000 in consideration of the profit sharing ratio in the above example. That is, as described above, the multimedia content service system 1000 does not display all of the keyword advertisement contents before exposure of the received keyword advertisement contents. Instead, the multimedia content service system 1000 filters and filters the keyword advertisement contents according to a predetermined criterion. Only display keyword ad content. The filtering criteria may be included in the keyword advertisement display module 7900.

Multimedia content service system 1000 that exposes a search result including the advertisement keyword advertising content (the keyword advertisement display module 7900 embedded in the multimedia content service system 1000 may perform the function.) May expose the received keyword advertisement content to the user according to its own policy. That is, the present invention includes exposing keyword advertising content based on text that can be obtained from the multimedia content in the process of transmitting the multimedia content. The playback of multimedia content on the user's computer requires the passage of time, which can be time zone if the passage of time is observed in terms of period or band.) Search results containing keyword advertising content may be lacking. In this case, the keyword advertisement display module 7900 of the multimedia content service system 1000 1) mixes the search results including the keyword advertisement contents in the previous time zone and the search results including the keyword advertisement contents in the current time zone. How to, 2) push the oldest of the search results containing the keyword ad content from the previous time zone with search results containing the keyword ad content generated in the current time zone, and 3) keyword ad content related to text based on the UCC tag. Since is not related to the playing time of the multimedia content, it may be possible to adopt a method of filling a search result including keyword advertising content that is insufficient with keyword advertising content related to the text based on the UCC tag.

Of course, although the representation of the keyword advertisement content as a search result including the received keyword advertisement content is expressed by the multimedia content service system 1000 in terms of expression, the function is combined with the multimedia content service system 1000 or The keyword advertisement display module 7900 as the program 9100 to be executed in conjunction is not excluded. That is, the relation between the keyword advertisement display module 7900 and the multimedia content service system 1000 is 1) when all are included in the same entire program 9100 operated by the same operator (when combined). 2) when the same operator is operated but operates as a separate program (9100) (3). 3) a separate program (9100) operated by separate operators or a communication between the two to cooperate with each other. There is a case.

When the keyword advertisement display module 7900 of the multimedia content service system 1000 summarizes the tasks performed by the multimedia content service system 1000, it can be summarized as follows. First, the keyword advertisement display module 7900 obtains keyword advertisement content obtained from the search keyword advertisement content providing server 3100, and considers the number of keyword advertisement contents obtained, the length or size of the keyword advertisement contents, and the like. The number of keyword advertisement contents to be displayed on a predetermined basis may be determined, and the keyword advertisement contents to be displayed may be synchronized or asynchronous with the multimedia contents being played to transmit the keyword advertisement contents to the user computer 9000. have. Of course, in this case, when additional meta information is transmitted from the keyword advertisement content providing server 3100 for information on the unit price (cost per click) of each keyword advertisement content or click-to-impression ratio, etc., the received keyword advertisement content meta is transmitted. Based on the information, it may be possible to filter whether or not the keyword advertisement content is transmitted based on a predetermined criterion (such as an advertisement unit price above a limit advertisement unit price, a clickthrough rate above a reference value, an advertisement unit price * click rate above a reference value, etc.).

The text acquisition module 3110, the keyword advertisement target text generation module 6610, and the keyword advertisement display module 7900 may be performed by the same subject. In particular, the text acquisition module 3110 and the keyword advertisement target text generation module 6510 are even more so. The operator of the keyword advertisement display module 7900 and the operator of the multimedia content player are preferably the same, but may be different. In other cases, the keyword advertisement display module 7900 may operate in the form of an application service provider (ASP) that provides its service to a person who provides at least one multimedia content player service. That is, a user who operates the keyword advertisement display module 7900 may expose his service to the user by interworking his keyword advertisement display module 7900 with a plurality of multimedia content players. In this case, it is more preferable that the person supplying the keyword advertisement display module 7900 supplies the text acquisition module 3110 and the keyword advertisement target text generation module 6510 to the ASP. In the above ASP, when the multimedia content player is a web multimedia content player, since the web multimedia content player operates on a website or a web server of a specific operator, the ASP method can be combined more easily.

The above description has been mainly based on the assumption that the multimedia content is transmitted to the user computer 9000 on the multimedia content service system 1000 by a streaming method, etc. However, this is because the multimedia content is played within the user computer 9000. The same is true for those skilled in the art. That is, the multimedia content service system 1000 extracts text information such as tag information and the like from the multimedia content that the user provides to the user, and combines keyword advertisement content therein to the user computer 9000. Provide content together with the keyword advertising content. Therefore, the playback subject of the multimedia content is not important in the spirit of the present invention, and the synchronization / non-synchronization of the provision of the multimedia content and the keyword advertisement content is a secondary problem. That is, when the text information is extracted from the tag information, the title information, the description information, and the like for the multimedia content such as a video, and the keyword advertisement content is synchronized / asynchronously provided to the user computer 9000, the specific frame of the video is displayed. It is hardly necessary to match the playback time with the exposure time of the keyword advertisement content. Therefore, in terms of the multimedia content service system 1000, only the multimedia content provided to the user computer 9000 and the interworking (correlation, matching) between the text included and extracted in the provided multimedia content are important. Whether multimedia content is played on the user or on the user computer 9000 becomes less important. In particular, when the multimedia content is an image file such as a photo, most of the reproduction of the image file occurs in the user's computer 9000 (the server of the system mainly reproduces a thumbnail file, Is transmitted to the user computer 9000, and is viewed in a browser running on the user computer 9000 / user computer 9000.), the multimedia content service system 1000 performs meta information linked to the image file. If only a 1: 1 correspondence between the tag information and the like and the multimedia file transmitted to the user is secured, the advertisement method of the present invention can be implemented. That is, when the multimedia content service system 1000 generates and transmits a web page including information about a specific image file to a browser of the user computer 9000, the image file is shown on the generated web page. At least one keyword advertisement content based on text information obtained from meta information such as tag information of the unknown file may be transmitted to a predetermined position such as below / side of the quality position. It will be apparent that the operation of the multimedia content service system 1000 is the same as the transmission of the video file.

Next, a description will be given of the synchronization between the multimedia content to be played back and the provision of keyword advertising content based on text obtained from the multimedia content. Subtitle information (including translated subtitle information) generated when a specific scene of the multimedia content is played in order to induce a user's action on the keyword advertisement content, such as attention to keyword advertisement content and a click on the keyword advertisement content. Or keyword advertising content related to text forming the caption information. Therefore, it will be necessary to synchronize the keyword advertising content with the caption information or caption information that fluctuate every moment.

Preferably, the synchronization is accomplished in one of three ways.

The first method is characterized by real-time synchronization of the search results including the keyword ad content including the text acquisition and the keyword ad content. With respect to the multimedia content being played at a specific point in time from the multimedia content, text is obtained from subtitles or captions within a time section (or frame section) to which the specific view belongs, and the keyword advertisement target text is obtained from the obtained text. And the keyword including the keyword advertisement content obtained by querying at least one keyword advertisement content providing server 3100 capable of providing a search result including keyword advertisement content with respect to the obtained keyword advertisement target text. The search result including the advertisement content may be displayed on a lower side, left side or right side, or a predetermined position of the player on which the multimedia content is being played. The method is a method in which the acquisition of the keyword advertisement target text and the display of the search result including the keyword advertisement content in the specific time interval (or frame interval) are synchronized in real time. The present method differs from the second method described later in that text can be obtained in real time even by using a voice recognition method instead of a caption or caption.

The second method is to obtain and store the search results including the keyword ad content including the text acquisition and the keyword advertising content, and to display the keyword advertising content when the obtained text appears in the caption or caption. to be. With respect to the multimedia content played at a specific point in time from the multimedia content, text is obtained from subtitles or captions within a section to which the specific view belongs, and before the time section (or frame section) to which the specific view belongs. Obtains keyword advertisement target text from text, and queries the obtained keyword advertisement target text to at least one keyword advertisement content providing server 3100 that can provide search results including keyword advertisement contents. Obtains and stores search results that include keyword advertising content. The stored keyword advertisement content is synchronized with the caption or caption information and the keyword advertisement content in accordance with a time point or time period (or frame period) where subtitles or caption information related to the text should appear. In this case, the keyword advertising content is preferably stored together with the time point or the time interval (or frame interval). That is, it may be desirable to store the time section (or frame section) information in the keyword advertisement content in the form of a meta tag or information that can be recognized by the keyword advertisement display module 7900. The keyword advertising content may be displayed on a lower side, left side or right side, or a predetermined position of the player on which the multimedia content is being played. The method does not have a large difference between the point in time at which the keyword advertisement content is obtained and the point in time at which a specific portion of the multimedia content in which subtitles or captions appear related to the keyword advertisement content are played (the former is slightly later than the latter, preferably 1). The difference between the units of the -10 time intervals (or frame intervals) is different from the third method described later.

In the third method, since the caption or caption is in the form of a file, the text in all captions or caption files is processed in units of the time interval based on the time interval (or frame interval) unit information included in the caption or caption. The search result including the keyword advertisement content including the keyword advertisement content corresponding to the text on a time interval basis may be obtained and stored including the time interval information. In this case, when the keyword advertisement display module 7900 plays the multimedia content, time section information included in the meta information of the multimedia content file played at a specific time point is included in the meta information of the keyword advertisement content file. The keyword advertisement content may be displayed by synchronizing with the time interval information.

Sites that handle so-called UCC multimedia content such as Youtube.com and pandora.tv allow users to upload multimedia content as UCC that they have taken, obtained or created, and send the uploaded multimedia content in a streaming manner. To play on your computer. The UCC multimedia content is relatively short, unlike movies and the like. Therefore, the following method may be applied to the UCC multimedia content as described above.

In case of acquiring the text included in the UCC tag included in the meta information of the UCC multimedia content file and displaying the keyword advertising content based on the text included in the UCC tag, the keyword advertising content is converted into the UCC multimedia content. Independently of the present invention, a method of displaying 1) at the start of playback of the UCC multimedia content, 2) during playback, or 3) at the end of playback of the UCC multimedia content may be implemented. In particular, when the UCC multimedia content is finished, the keyword advertisement content may be collected and displayed.

The method is most suitable for text subtitles or caption files, but a speech recognition method may also be applied. For this purpose, preprocessing of multimedia content to be played by the player is required. The preprocessing plays the multimedia content file, obtains text from the voice information from the voice information of the reproduced multimedia content, and, based on the received text, 1) the text itself, 2) a keyword advertisement in the text. Obtaining a target text and then selecting at least one selected from the keyword advertisement target text and 3) a search result including the keyword advertisement content including the keyword advertisement content as the keyword advertisement target text. You can save it accordingly. The keyword ad content including the keyword ad content as the 1) the text itself, 2) the keyword ad target text obtained from the text, and then the keyword ad target text or 3) the keyword ad target text obtained by the player. The search results included may be selected from any one of the above-described methods, and as a result, the keyword advertisement contents synchronized with the multimedia contents may be displayed to the users.

The preprocessing of the multimedia content may in particular preprocess the multimedia content file itself, wherein the pre-processed 1) the text itself, 2) the keyword advertised text from the text is obtained and then the keyword advertised object. Text and 3) the keyword advertisement target text may include a search result including the keyword advertisement content including the keyword advertisement content. In addition, when the multimedia content is played on the server by the web multimedia content player, the preprocessing of the multimedia content should be preprocessed before the web multimedia content player plays the multimedia content and is transmitted to the user by streaming or the like. 1) the pre-processed text itself, 2) the keyword ad target text obtained from the text, and then the keyword ad target text and 3) the keyword ad content including the keyword ad content as the keyword ad target text. Search results should be stored in association with the multimedia content file.

Next, the present invention will be described in more detail with reference to preferred embodiments. Once again, common elements are first summarized before describing embodiments of the present invention. In order to carry out the inventive concept, 1) a text acquisition module 3110 is required to extract text from multimedia contents, and the text acquisition module 3110 generates a keyword advertisement text from the text obtained. 2) a keyword advertisement target text generation module 6510 is required, and 3) a keyword advertisement content providing server 3100 for generating a search result including advertisement keyword keyword contents for the keyword target advertisement text. There is a need for a 4) multimedia content providing module for streaming multimedia content to users and a 5) keyword advertising display module 7900 for exposing search results including the advertising keyword advertising content.

Various embodiments may occur according to who, how, and when the above 1) to 3) are performed, and whether the operating subjects are the same. Since the relationship in terms of the subject of 4) and 5) has been described above, no special explanation is given except in special cases. Functions performed by each module, such as the text acquisition module 3110, the keyword advertisement target text generation module 6610, and the keyword advertisement display module 7900, have been described above sufficiently, and thus, this embodiment will be described. In this section, we will focus on the composition of the entire subject and the range of modules included in each subject.

In the above description, the keyword advertisement target text generation module 6510 has been described for generating keyword advertisement target text in real time from meta information included in specific multimedia content information selected by the user (especially video content information). Meanwhile, the keyword advertisement target text generation module 6510 may obtain information about each multimedia content with respect to at least one multimedia content file in the multimedia content DB 1110 of the multimedia content service system 1000. Next, 2) obtain meta information contained in each multimedia content file, and 3) select any one or more of the methods of generating the keyword advertisement target text in real time described in the present specification, and in the selected method, each multimedia content The keyword advertisement target text may be generated in advance for each, and 4) the generated keyword advertisement target text may be stored in correspondence with each multimedia content. In this case, when the multimedia content is provided to the user computer 9000, the multimedia content may be provided explicitly or hidden together with information on the keyword advertisement target text previously generated and stored. When the user makes a selection by clicking on a specific multimedia content, the user can query the keyword advertisement content providing system 3000 with the keyword advertisement target text included in the selected multimedia content. Meanwhile, the pre-generated keyword advertisement target text forms another content of meta information from the viewpoint of the multimedia content. Therefore, the meta information of the specific multimedia content of the present invention may be interpreted as including pre-generated keyword advertisement target text information. Meanwhile, when the pre-generated keyword advertisement target text is borrowed as meta information, the meta information acquisition module 5100 may obtain the pre-generated keyword advertisement target text, and the keyword advertisement target text generation module 6610. Does not function, or approves without modifying the pre-generated keyword ad target text, or if there is a difference or more than a preset value at the time of pre-creation and the present time, or if there is a new policy, the pre-generated keyword ad target text Can be modified or changed.

In this case, there are two methods for querying the keyword advertisement content providing system 3000 with the keyword advertisement target text included in the selected multimedia content. First, the multimedia content service system 1000 obtains selection information on a specific multimedia content, and then transmits the keyword advertisement target text stored corresponding to the multimedia content to the keyword advertisement content providing system 3000. A method of obtaining at least one keyword advertisement content from the keyword advertisement content providing system 3000. Second, a script program such as JAVA Script and the like, and pre-generated keyword advertisement target text corresponding to the multimedia content are included in a page including the multimedia content delivered to the user. A function of querying the keyword advertisement target text to the keyword advertisement content providing system 3000 and obtaining keyword advertisement content from the keyword advertisement content providing system 3000, and obtaining the obtained keyword advertisement content from the surroundings of the multimedia content. There is a method of displaying the preset keyword advertisement content display area 100.

On the other hand, when the keyword advertising content is delivered to the multimedia content service server 1100 through the meta information-based keyword advertising mediation system 2000, the meta information-based keyword advertising mediation system 2000 is applied to the keyword advertising content. It is possible to insert code in which occurrence information such as a click is automatically obtained to the user.

Multimedia Contents Service System (1000)

In the mediation model, the multimedia content service system 1000 includes a multimedia content service server 1100 and a meta information-based keyword advertisement server 6000. The meta information-based keyword advertising server 6000 in the mediation model does not have the function of the keyword advertising control module 6900 in the non-weighting model or includes only a limited function module. The function of the multimedia content service server 1100 in the mediation model is substantially the same as the function of the multimedia content service server 1100 in the nondisclosure model. First, the multimedia content service system 1000 will be described based on a mediation model having no function of the keyword advertisement control module 6900 in the non-overlapping model.

In the mediation model, since the multimedia content exists in the multimedia content service system 1000, meta information of the multimedia content also exists in the multimedia content service system 1000. In this case, the meta information-based keyword advertisement server 6000 of the multimedia content service system 1000 may include the meta information acquisition module 5100 and the keyword advertisement display module 7900 in the non-weighted model. In addition, it is preferable to further include a meta information transmission module 5200 and a keyword advertising content receiving module (5300). The meta information transmitting module 5200 transmits the obtained meta information to the meta information-based keyword advertisement mediation server 2100 which is a third server. That is, in the non-disclosure model, the meta information obtained by the meta information acquisition module 5100 is transmitted to the keyword advertisement control module 6900, whereas in the mediation model, the meta information is transmitted to the meta information-based keyword advertisement mediation server 2100. Meanwhile, at least one keyword advertisement content is transmitted from the meta information-based keyword advertisement mediation server 2100 or in some cases from the keyword advertisement content providing server 3100 to the multimedia content service system 1000. The keyword advertisement content receiving module 5300 of the content service system 1000 receives the keyword advertisement content that is transmitted.

Meanwhile, processing of the received keyword advertisement content by the keyword advertisement display module 7900 is the same in the mediation model and the non-intermediation model.

Although the keyword advertisement display module 7900 may allow the keyword advertisement content receiving module 5300 to process all the received keyword advertisement contents, the keyword advertisement satisfying a predetermined condition with respect to all the received keyword advertisement contents.

In particular, the keyword advertisement target text generation module 6510 included in the multimedia content service server 1100 may be configured such that the meta information acquisition module 5100 of the multimedia content service server 1100 receives only tag information or tag information. In this case, the tag information is transmitted as the meta information to the meta information-based keyword advertisement mediation server 2100. In this case, the keyword advertisement target text generation module 6510 of the meta information-based keyword advertisement mediation server 2100 does not need to perform any other function. In extreme cases, if the meta information-based keyword advertisement mediation server 2100 obtains and processes only tag information, the meta information-based keyword advertisement mediation server 2100 does not have the keyword advertisement target text generation module 6510, The keyword advertisement target text generation module 6510 may perform only a simple pass function without performing an independent function. The premise of the extreme case is that the meta information-based keyword advertisement mediation server 2100 obtains and processes only tag information from all the multimedia content service systems 1000 connected to the meta information-based keyword advertisement mediation server 2100. Even if it is obtained, it should not be processed. If the multimedia content service system 1000 receives only the tag information, and the multimedia content service system 1000 receives other text information other than the tag information, the meta information-based keyword advertisement mediation server 2100 may receive the tag information. It may be desirable to include the keyword advertisement target text generation module 6510 to perform meta information-based keyword advertisement intermediary services for various multimedia content service systems 1000. Therefore, regardless of the presence or absence of the keyword advertisement target text generation module 6510 in the multimedia content service server 1100, the keyword advertisement target text generation module 6510 in the meta information-based keyword advertisement mediation server 2100. Is preferably present.

Next, the meta information-based keyword advertisement mediation system 2000 that is the core of the mediation model will be described in more detail. The meta information-based keyword advertisement mediation system 2000 of the present invention processes meta information on at least one multimedia content from the multimedia content service system 1000, so that at least one keyword advertisement content based on the meta information is stored. It performs a function of mediating to be delivered to the multimedia content service system 1000. The basic configuration of the meta information based keyword advertisement mediation system 2000 and the meta information based keyword advertisement mediation server 2100 will be described first, and then the meta information based keyword advertisement mediation system 2000 and the multimedia content service server 1100 will be described. The role sharing model of is also described in detail.

Meta Information-based Keyword Advertising Mediation System (2000)

The meta information-based keyword advertising mediation system 2000 will be described in more detail with reference to FIG. 13. The meta information-based keyword advertisement mediation system 2000 is composed of a meta information-based keyword advertisement mediation server 2100 and other servers necessary for smooth operation of the meta information-based keyword advertisement mediation server 2100. Are obvious to those skilled in the art and are omitted herein. The meta information-based keyword advertisement mediation server 2100 includes a meta information receiving module 9800 and a keyword advertising control module 6900, and optionally a click generation information receiving module 8900 and / or a multimedia content service system ( 1000) further includes a management module. Meanwhile, the meta information-based keyword advertisement mediation server 2100 receives the keyword advertisement content from the keyword advertisement content providing server 3100 and transmits the keyword advertisement content to the multimedia content service system 1000. ) May be included. The keyword advertisement content transmission module 8800 may receive keyword advertisement content from the keyword advertisement content providing server 3100 and transmit the received keyword advertisement content to the multimedia content service system 1000 without any filtering. Referring to the keyword advertisement control policy DB 6640 of the keyword advertisement control module 6900, only the keyword advertisement content selected by the keyword advertisement content selection module 6550 may be transmitted to the multimedia content service system 1000.

When a click occurs on a specific keyword advertisement content in the user computer 9000, the keyword advertisement content providing server 3100 may recognize that the click has occurred. The keyword advertising content includes a target URL or URI (address in a virtual space, such as a website or web page, which is ultimately shown to the user) and ID / identifier information of the keyword advertising content. In this case, when one clicks on the keyword advertisement content, the method moves to a specific site such as a keyword advertisement content providing server 3100, and the keyword advertisement content providing server 3100 redirects to the target URL or URI. If the keyword is redirected, the keyword advertisement content providing server 3100 may know the click generation information from the user computer 9000. Since the keyword advertisement content providing server 3100 is redirected, the user computer 9000 may be different from the virtual space corresponding to the target URL or URI. The content corresponding to the address is received. On the other hand, when a click or the like occurs in the keyword advertisement content in the meta information of the keyword advertisement content, a command for transmitting the occurrence information of the click to a specific server together with the ID / identifier information of the keyword advertisement content in which the click occurred (scripter And the like). Such a method is an exemplary method of obtaining click generation information, and it will be obvious that the present invention includes all methods that are obvious to those skilled in the art of obtaining click generation information.

The meta information-based keyword advertisement mediation server 2100 may optionally further include a click generation information receiving module 8900. The click generation information receiving module 8900 is a module that receives an action such as a user's click on a specific keyword advertisement content. The click occurrence information is 1) a method of obtaining from the keyword advertisement content providing server 3100, 2) a method of obtaining from the multimedia content service server 1100, 3) a method of directly obtaining from the user computer 9000, and the like. There is this. The keyword advertisement content includes meta information. The meta information-based keyword advertisement mediation server 2100 receives keyword advertisement content from the keyword advertisement content providing server 3100 and transmits the keyword advertisement content to the multimedia content service server 1100. Before the transmission, it is preferable to add meta information for the meta information-based keyword advertisement mediation server 2100 to the obtained keyword advertisement content. The meta information added by the meta information-based keyword advertisement mediation server 2100 may be directly or indirectly obtained from the meta information-based keyword advertisement mediation server 2100 when the keyword advertisement content is clicked.

Record the display time of one or more specific keyword advertising contents, and monitor whether or not a click occurs on the specific keyword advertising contents until a predetermined time through the click generation information receiving module 8900, and then, within the predetermined time, When the click generation information on the advertisement content is obtained, it is preferable not to change at least one or more keyword advertisement contents displayed on the user computer 9000 from a time point at which the click generation information is obtained to a preset second time.

 If the computer program 9100 does not obtain additional click generation information on the keyword advertisement content displayed on the user computer 9000 by the second time, the keyword advertisement content received from the keyword advertisement content providing server 3100. It is preferable to display on the user computer 9000 a predetermined number of keyword advertisement contents selected from among the keyword advertisement contents except the keyword advertisement contents displayed on the user computer 9000.

The computer program 9100 may include at least one keyword to be displayed on the user computer 9000 based on a specific time point among the keyword advertisement contents when the keyword advertisement contents received from the keyword advertisement content providing server 3100 are plural. A keyword advertisement content selection module 6550 for selecting advertisement content; And a click generation information receiving module 8900 for receiving click generation information on the keyword advertisement content displayed on the user computer 9000, wherein the computer program 9100 includes at least the information displayed on the user computer 9000. Record the display time of one or more specific keyword advertising contents, and monitor whether or not a click occurs on the specific keyword advertising contents until a predetermined time through the click generation information receiving module 8900, thereby receiving the click generation information receiving module 8900. In the case where click generation information on the specific keyword advertisement content is obtained within a predetermined time period through), it is preferable to display the keyword advertisement content related to the keyword advertisement content in which the click occurs on the user computer 9000.

 The keyword advertisement contents related to the keyword advertisement contents in which the clicks are generated are (a) the keyword advertisements obtained by transmitting the at least one keyword advertisement target text which is specified by the keyword advertisement contents in which the clicks are transmitted to the keyword advertisement contents providing server 3100. In the case of the content, at least one or more keyword advertisement contents obtained when the specific keyword advertisement target text is transmitted to the keyword advertisement content providing server 3100, and (b) at least one or more specific keyword advertisement contents in which the click occurs. In the case of keyword advertisement content obtained by transmitting keyword advertisement target text to the keyword advertisement content providing server 3100, the keyword target advertisement text derived from the same meta information as the meta information on which the keyword advertisement target text is based. Advertising content At least one or more keyword advertisement contents obtained by transmission to the server providing server 3100, and (c) at least one or more keyword advertisement target texts which are specified by the keyword advertisement contents in which the click has occurred are transmitted to the keyword advertisement content providing server 3100. In the case of the obtained keyword advertisement content, when the specific keyword advertisement target text belongs to a specific group, and when there is another keyword advertisement target text other than the specific keyword advertisement target text in the group, the other keyword advertisement target text is included in the keyword. Preferably, at least one selected from at least one keyword advertisement content transmitted to the advertisement content providing server 3100 and obtained.

The computer program 9100 may include: a click generation information receiving module 8900 for obtaining click generation information on keyword advertisement content displayed on the user computer 9000; And a click generation information transmitting module 9900 for transmitting the obtained click generation information to a predetermined server. It includes any one or more of, the acquisition of the click generation information is obtained directly from the user computer 9000, and transmitting the click generation information is to transmit to the keyword advertising content providing server 3100, It is preferably at least one selected from those transmitted to a predetermined third server.

The video may be at least one selected from a live-action video, a non-live video, a UCC video, a movie, a flash video, a real-time broadcast, and a recorded broadcast including meta information in a text format.

Next, a case in which a script program such as Javascript is included in the present invention will be described in more detail. The script program is executable in relation to the browser. In the present specification, one of the scripting languages is described as JavaScript, but the present invention is not limited to JavaScript, and furthermore, if a language other than the scripting language can perform the functions described by the present invention, such a language Of course, it is obvious that the program is included in the present invention.

The multimedia content service system 1000 includes any means for providing multimedia content to the user computer 9000 via a wired or wireless network in a web page (not in the web) to be transmitted to the user computer 9000. It is possible to insert code such as JavaScript into a program in a predetermined language such as html constituting the above. The JavaScript code may 1) obtain meta information from the multimedia content information, and 2) communicate with the multimedia content service system 1000, or the content of the keyword advertisement control policy DB 5320 is written to the script program. When programmed, the keyword advertisement target text generation module 6510 may function independently of the communication with the multimedia content service system 1000. 3) The keyword advertisement content providing system 3000. ) May obtain keyword advertisement content from the keyword advertisement content providing system 3000 to serve as the keyword advertisement content acquisition module 6630, and 4) the keyword in the same manner as 2). May serve as an advertisement content selection module 6550, and 5) the keyword ad. 6) may include the display module (7900, 7800), and 6) when the event detection function is included, click information on specific keyword advertising content may be obtained from the user computer (9000). May be delivered to the multimedia content service system 1000 or the keyword advertisement content providing system 3000, and 7) there is at least one built-in timer program to generate various types of information generated by a browser of the user computer 9000. You can check the time for the event (video play, click occurrence, etc.), 8) You can display the preset number of keyword ad content in the preset method in the preset position, 9) Link to JavaScript If the user clicks on a link, etc., the JavaScript associated with the link is executed to preset 10) When the click information about a specific keyword advertising content is obtained, it may detect the click event and pause the playback of the multimedia content, and the video information that is being streamed and delivered is no longer available. It is also possible to send a temporary request to the multimedia content service system 1000 so that it is not streamed, and 11) it is possible to transmit and receive data with a predetermined server. In particular, when the JavaScript code performs asynchronous communication with the multimedia content service server 1100 or a predetermined server, a rich experience can be given to a user without putting a heavy load on the server.

Most of the functions performed by the JavaScript code are essentially 1) a role performed by the meta information-based keyword ad server 6000 / meta information-based keyword ad mediation server 2100 / meta information-based keyword ad providing server 4000. (Especially control functions), 2) communication with the servers, and 3) user computer 9000 event generation processing. Since the user computer 9000 and the multimedia content service server 1100 can communicate, the number of combinations of who and how to share various roles becomes enormous. In particular, the meta information-based keyword advertising server 6000 ) / The meta information-based keyword advertisement mediation server 2100 / meta information-based keyword advertisement providing server 4000 is further divided and combined to increase the number. Therefore, for convenience of description, a role-sharing model will be described with reference to important functions centered on the relationship with the meta information-based keyword advertisement server 6000, but the spirit of the present invention is not limited thereto. On the other hand, the JavaScript code may perform almost all the functions of the meta information-based keyword ad server 6000 described above, which means that the user computer 9000 installer described in the user computer 9000 installer model It will be comparable to the function performed. That is, the JavaScript code may obtain meta information included in the multimedia content transmitted to the user computer 9000, generate the keyword advertisement target text from the meta information, and generate the keyword advertisement target text from the keyword advertisement. By transmitting to the content providing server 3100 to obtain the keyword advertising content, it is possible to display the keyword advertising content in a predetermined manner in a predetermined position, to obtain various events such as a click occurs, and to obtain the received event It can also be sent to a preset server.

Hereinafter, each of the functions performed by the JavaScript code will be described in more detail based on a role sharing model.

First, the JavaScript code may perform a function of the keyword advertisement display module 7900. That is, the JavaScript code may allow the obtained keyword advertisement content to be displayed at any time from any time, including any form / action at any position. For example, in the drawings, the keyword advertising content is placed at the bottom of the multimedia content. However, this is merely an example, so that a layer is formed on the multimedia content and the keyword advertising content is displayed on the layer. In addition, the n keyword advertising content may be rolled at a predetermined cycle at a predetermined position, and, if there is a layer, may be turned behind the multimedia content and then popped forward of the multimedia content. Meanwhile, when the keyword advertisement content is displayed, the font, color, etc. of the keyword advertisement content may not only be adjusted, such as being initially displayed in a large font and then decreasing in font, but also may provide various animation effects. In particular, displaying the keyword advertisement content of the present invention on a layer will be more meaningful when the user computer 9000 has a physically small display area such as a mobile phone. On the other hand, in this case, when the user clicks on the keyword advertising content or makes a touch or other action equivalent to the click, the link information included in the keyword advertising content is activated to allow the user to view the screen intended by the advertiser. At this time, the javascript code receives the event when the user clicks, etc., and transmits a command requesting the number of days if the multimedia content is being played to a module that performs the multimedia content playing function. May cause playback to pause. This may be particularly useful when the screen size is small, such as a mobile phone, or when a page containing the advertiser's content linked to keyword advertising content is not allowed to open in a popup window. On the other hand, when the user computer 9000 uses two or more monitors or uses a large-screen monitor, the JavaScript code avoids the play area of the multimedia content independently of the pause of the play of the multimedia content. It is preferable to open the page of the advertiser. To this end, the JavaScript code obtains the position / coordinate information (each corner information of the rectangular area) of the multimedia content playing area from the user computer 9000, and the position and size of the popup window in consideration of the position / coordinate information. Can be adjusted.

Second, the JavaScript code may include a timer function to check a time. Since the timer can measure time, 1) it can control which keyword ad content is exposed for what time, and 2) allow n keyword ad content to be rolled one by one or several times at predetermined intervals. , 3) keyword ad content can be measured without the click.

Third, the JavaScript code may be exposed in at least one or more keyword advertisement contents which are obtained once or plural times during the playing time by obtaining the playing time information of the multimedia content. The number of keyword advertising contents can be controlled. On the other hand, if the exposure to the keyword ad content obtained by the JavaScript code itself is finished, or if it is determined that the number of keyword ad content is insufficient (especially when the duration of the multimedia content is very long, etc.) additional keyword ad content In order to obtain, 1) transmit additional keyword advertising content to any one or more of the meta information-based keyword advertising server 6000 / meta information-based keyword advertising mediation server 2100 / meta information-based keyword advertising providing server 4000. Or 2) at least one of the meta information-based keyword advertisement server 6000, the meta information-based keyword advertisement mediation server 2100, and the meta information-based keyword advertisement providing server 4000. Tags, titles, and descriptions that are not used to obtain the keyword ad content that has been exposed Transmits the information to the meta information-based keyword ad server 6000, the meta information-based keyword ad mediation server 2100, the meta information-based keyword ad providing server 4000, or 3) retransmits the keyword ad content that has already been received and exposed. You may or may not be exposed. Meta information that is not used to obtain the exposed keyword advertising content includes information about keyword advertisement target text provided for acquisition of the keyword advertisement contents in the acquired keyword advertisement contents, and is related to the keyword advertisement target text among the meta information. Meta information except meta information. If the meta information that is primarily used for the acquisition of keyword ad content is tag information, this is the title information or description information, and the unused tag information is used when n-1 or less of n tag information is used. If m-1 groups are used to obtain keyword ad content when the m keyword target text extracted from n tag information or title or description information is managed as m groups, the unused group is used. Meta information corresponding to the included keyword advertisement target text may correspond to this. Meanwhile, when requesting transmission of keyword advertising content to the keyword advertising content providing server 3100, a number / rank / order may be determined. In this case, when the number / rank / order obtained first is n, It may also request transmission of keyword advertising content corresponding to n + 1 or more. Of course, the meta information-based keyword ad server 6000 / meta information-based keyword ad mediation server 2100 / meta information-based keyword ad providing server 4000 or the number of JavaScript code to obtain the keyword advertising content / When determining the rank / order, it may be possible to control to obtain more keyword advertisement content when the play time information is long in consideration of play time information of the multimedia content. On the other hand, as a way to obtain more keyword ad content, 1) to obtain keyword ad content by dividing it by the type of meta information such as tags, titles, and descriptions, and 2) the same kind of meta information as multiple or multiple groups. Obtaining keyword advertising content by requesting the keyword advertising content providing server 3100 in a divided manner; 3) generating a plurality of keyword advertisement texts from title information, tag information, description information, etc. By using any one or more methods of obtaining keyword advertisement contents by querying each text group for advertisement, a sufficient number of keyword advertisement contents may be obtained.

On the other hand, if the multimedia content has subtitles and the like, if the subtitles are processed as the description information and the like, the subtitle information in a specific time point (smi file format, etc.) is displayed as text as a subtitle to be displayed at a specific time period (from t1 to t2). Keyword content that is displayed at a specific time interval (from t1 to t2 to t3 ..until ti) or at a specific time interval (e.g., for tj seconds, etc.). That is, the caption information is obtained as meta information, and the meta information based keyword advertisement server 6000 / meta information based keyword advertisement mediation server 2100 / meta information based keyword advertisement providing server 4000 with respect to the caption information. One of the JavaScript codes may be processed to generate a keyword advertisement target text, and the keyword advertisement content may be obtained from the keyword advertisement content providing server 3100 with respect to the generated keyword advertisement target text. When the keyword advertisement content is obtained using the caption file as the meta information, the change of the keyword advertisement content may be changed according to the meta information for a specific time input to the material. That is, it is preferable that the keyword advertisement contents displayed between t1 and t2 are obtained as keyword advertisement target text generated with subtitles obtained between t1 and t2 of the smi file.

Fourth, the JavaScript code communicates with the multimedia content service system 1000 to query / query the keyword advertisement control policy DB 5320 or to display the contents of the keyword advertisement control policy DB 5320 in the JavaScript program. In this case, the mobile terminal may perform the role of the keyword advertisement content selection module 6550 of the present invention as described above independently of the communication with the multimedia content service system 1000.

Fifth, the JavaScript code communicates with the multimedia content service system 1000 to query / query the advertisement keyword DB 6570 and / or the keyword advertisement control policy DB 5320 or to remotely call the stemmer and the like. It may be used to provide the meta information and receive the result generated by the stemmer, thereby serving as the keyword advertisement target text generation module 6510. On the other hand, when the contents of the keyword keyword DB 6657 and / or the keyword advertisement control policy DB 5320 is programmed in the JavaScript code, it is independent of whether or not communication with the multimedia content service system 1000 is performed. As such, it may serve as the keyword advertisement content selection module 6650 of the present invention described above. In brief description of the latter, when various advertisement keywords included in the advertisement keyword DB are provided in a text string or other manner, the JavaScript code inquires the obtained meta information in the text string to find a corresponding text. It can be extracted and generated as keyword advertising target text.

Sixth, the JavaScript code may perform an event detection function such as a click and an event occurrence information transmission function. Unlike a typical link, a link including JavaScript may cause a specific javascript related to the link to be driven when the user clicks or touches the link. In this case, the specific javascript may perform functions of 1) checking occurrence of an event called click, 2) transmitting click information to a predetermined server, and 3) connecting to a content page of an advertiser related to a link. . On the other hand, the JavaScript code is any event related to the playback of the multimedia content, such as the start of playback of the multimedia content received by the streaming method and / or the end after the completion of playback and / or the pause and / or termination by the user, etc. The occurrence information may be obtained and transmitted to a predetermined server, or used for obtaining / displaying keyword advertisement content. For example, when the playback of the multimedia content is finished, the JavaScript code may prevent the keyword advertisement content from being obtained from a predetermined server any more, but the playback of the multimedia content by the end of the playback or by the user At this pause, the largest number of keyword ad content may be available or displayed. Of course, the JavaScript code only receives the occurrence of an event, performs only a communication function of transmitting to a predetermined server, and allows the predetermined server to determine how and how to display the keyword advertisement content in response to the event. can do. Since the combination of such role-sharing models is so diverse, it is not described in the present specification that all the combinations one by one.

Seventh, any one or more of the JavaScript code or the meta information-based keyword ad server 6000 / meta information-based keyword ad mediation server 2100 / meta information-based keyword ad providing server 4000 are 1) specific multimedia content, 2) collect user's behavior information in history for the specific keyword advertisement target text and 3) specific keyword advertisement content, transmit the information to a predetermined third server, or perform statistical analysis on the behavior information. Can be. For example: 1) When ni keyword advertising content is exposed from n1 to specific multimedia content, n2 keyword advertising content ranked first and n5 keyword advertising content ranked second in terms of impression for a predetermined period of time, or 2) When the keyword ad content from nj to n (j + k) was exposed for a given keyword ad text or a group of ad text, the n (j + 1) keyword ad content had the highest clickthrough rate, and n (j + k-1) It may be able to perform statistical analysis on user behavior information such as keyword advertising content having the highest average advertising revenue. As a result of the statistical analysis process, 1) it is possible to rank the keyword advertising content that is expected to receive the most clicks on specific multimedia contents, the keyword advertising content that is expected to generate the highest advertising revenue, and 2) the specific keyword advertising. The target text may be ranked in the keyword advertising content that is expected to receive the most clicks, and the keyword advertising content that is expected to generate the highest advertising revenue. When the javascript code obtains such sequence information or the meta information-based keyword advertisement server 6000 / meta information-based keyword advertisement mediation server 2100 / meta information-based keyword advertisement providing server 4000 has it. When the selection information is obtained from the user for the specific multimedia content or the specific keyword advertisement target text is generated, the keyword advertisement content to be provided to the user computer 9000 may be selected in consideration of the sequence information. . Of course, even when there is sequence information on the keyword advertising content, if the relatively long time elapses, the keyword advertising content cannot be obtained (when an advertiser lowers / cancels an advertisement, etc.), or an advertisement condition (per click). If the advertiser spends) or the advertiser's advertising content changes, the sequence information may not be used 100%. However, since such sequence information is unlikely to be invalidated in a relatively short period of time (particularly, changes in advertisement contents are not frequently occurring, and advertisements are canceled or canceled relatively less frequently). .) The validity of such sequence information will be high.

Next, a brief description will be given of a dedicated multimedia playback program, which is a special form of the installed program 9100 installed in the user computer 9000. The above description focuses on the form of accessing the multimedia content service system 1000 in the form of a web browser. The web browser may be a dedicated web browser for a specific multimedia content service system 1000. Will be common. Meanwhile, in the present invention, the role of the web browser is 1) to obtain multimedia content by communicating with the multimedia content service system 1000, 2) to obtain keyword advertisement content, and 3) to an event generated at the user computer 9000 stage. And 4) other performance of the functions mentioned herein. On the other hand, the functions of 1) to 4) are also performed by a dedicated multimedia player program (broadly, a browser is also installed) installed in a user's HDD or other temporary non-temporary fixed memory means. Could be. An example of the dedicated multimedia player program 9210-1 is a windows media player provided by Microsoft, a real player, or a gom player provided by a Korean company. This is especially the case that the dedicated multimedia playback program 9110-1 is often installed in a set-top box such as an IPTV. Therefore, as shown in FIG. 26, it is preferable that things such as the installation program 9100 of the present invention are installed in the set-top box such as the IPTV to execute the present invention idea. If the configuration of the dedicated multimedia player program is expanded or changed, or a function is added, the dedicated multimedia player program can sufficiently perform the function of the (web) browser of the present invention. Meanwhile, many additional functions may be added to the dedicated multimedia player program, and the computing power (memory, CPU) of the user computer 9000 may be sufficiently used, and thus the processing related to the voice recognition described above may be performed. (If the multimedia content service system 1000 streams multimedia content, the multimedia content service server 1100 or other server needs to play the multimedia content in order to perform voice recognition. On the other hand, in the case of a browser, it is possible to perform various functions in a scripting language such as JavaScript, but the dedicated multimedia player can use a much more powerful language than the scripting language. Free It may be possible to perform various functions. In other words, it is not easy to construct a large advertising keyword DB or to hold dictionary data for morphological analysis with ordinary JavaScript, but in the case of the dedicated multimedia player program, it is not difficult to guarantee the freedom of functions. This is an example.

In particular, the JavaScript code or the dedicated multimedia player program, when the multimedia content service server 1100 receives the multimedia content by a file transfer method rather than a streaming method, and provides the user to play the multimedia content, the multimedia The keyword advertisement content is independently generated from the multimedia content service server 1100 or other servers mentioned in the description of the present invention, regardless of whether the predetermined condition is achieved or not, while monitoring the content from the time of playback until the end and after the type. It may be able to function by displaying the keyword advertising content in a predetermined manner in the preset keyword advertising content display area after receiving one or more times.

The present invention is directed to multimedia content including meta information, and the multimedia content is not only one type of multimedia content (for example, a video, an image, a sound), but also 1) at least two or more types. May also be multimedia content, or 2) a plurality of one or more types of multimedia content are combined, or a multimedia content in which 1) and / or 2) are combined in a text format. Will be apparent to those skilled in the art.

Commercial tags

Next, a method of applying the present invention to the IPTV will be described. IPTV can be referred to as interactive TV, interactive TV, digital TV, and the like, but is a TV in which a device (for example, a set-top box, etc.) capable of connecting to an interactive network such as the Internet is embedded or externally combined. Unlike a computer, a TV is usually operated by a remote control or the like. On the other hand, since the remote control functions to select a specific content or perform operations through a TV screen from an IPTV point of view, the role of the remote control is at least some of the roles of a pointing device such as a mouse of a computer and a keyboard. Equivalent to performing.

IPTV combined with a network access control device such as a set-top box (hereinafter, referred to as a set-top box, but the inventive concept is not limited to this particular type of device) is connected to a personal computer connected to a typical Internet. Can play an equal role Therefore, the present invention described in terms of a PC, not unique to the TV, such as a case where a user or a producer or distributor of a video inputs meta information such as a title, tag, and description information related to the video to a video transmitted through IPTV, etc. Naturally, the idea can be applied to IPTV / station systems. Hereinafter, a description will be given of how the present invention can be applied when the IPTV / broadcasting station system is expanded from IPTV to Internet broadcasting, but what is described below is applied to the multimedia content service system 1000 or the personal computer of the present invention. It will be apparent to those skilled in the art that the present invention can also be applied.

Video transmitted to IPTV may be further attached to commercial tags such as commercial tags. In general, tags, etc., which are combined with UCC videos, are mostly non-commercial tags that are combined by creators of videos for ease of search or classification.

However, a video obtained through a wired or wireless network in an interactive TV such as IPTV (Because the broadcast video is transmitted by file downloading or streaming method, this may also be called a video, and a broadcasting system or a video distributor system that provides IPTV video). Becomes a kind of multimedia content service system 1000 of the present invention. In connection with IPTV, the term "broadcasting video" will be described. However, it will be clear that this video is one of the video of the present invention. Tags may be combined by the creator, distributor, and other value added adders of the video.

First, there may be time independent tags for the entire broadcast video. Such tags will be representative of time independent commercial tags. A time-independent commercial tag is a tag that contains information about: 1) various props, 2) places (including real estate, backgrounds, locations, locations of specific services), and 3) costumes and accessories that appear on the screen of the broadcast video. These are tags that do not contain time information in the log tag information. These time-independent commercial tags may include numbers related to a product or service, such as: 1) name information on the place or service of the product, 2) name information on the place, 3) brand information on the product or service, and 4) specifications or price ranges for the product or service. , Only exposing information about ratings, and the like.

For example, 1) there may be a case where only the name information of a product called a bed is exposed, such as <small> bed </ strong>. Where <prop> and </ prop> are meta information indicating the type or type of tag. When there are various time-independent commercial tags, when meta information indicating the format or type of such a tag is provided, only the tag information corresponding to the specific format or type can be selected to implement the advertisement idea of the present invention. Then, 2) you can include your brand, such as <prop> ace bed </ prop>, and 3) you can have a tag that contains information such as specifications, such as <prop> king bed </ prop>. , 4) Place information may be included, such as <Shooting Site> Dogok-dong Tower Palace </ Shooting Area>. At this time, it is a matter of course that the meta information acquisition module 5100 of the present invention can obtain the time independent commercial tag, and the above-described time independent commercial tag is treated as a tag described in the present invention. The idea of the present invention may be implemented. Of course, even if there is no information on the type or type of the tag it will be obvious to those skilled in the art that the spirit of the present invention can be implemented. In addition, weights may be different with respect to the type or type of the tag. For example, you might want to weight the contents of a tag associated with a prop twice as much as for a place. Of course, the tag may have a hierarchical structure as follows, and the meta information acquisition module 5100 recognizes the hierarchical structure as follows, and it will be common since it applies xml parsing technology. The structure of the tag for the props and places may be as follows. Of course, markup languages such as <props>, <prop>, <property name>, etc., mentioned below are <goods>, <good>, <good_name>, </ goods>, </ good>, </ It is common in English, such as good_name>, but is expressed in Korean for convenience. On the other hand, tags in Korean are not always processed.

<Props>

<Accessories>

<Proper name> bed </ accessory name>

<Standard> king size </ standard>

<Brand> ace </ brand>

</ Prop>

<Accessories>

<Property name> coffee </ property name>

<Brand> Starbucks </ brand>

</ Prop>

<Props>

<Places>

<Place>

<Place name> Dogok-dong Tower Palace </ Place name>

<Standard> 45 equilibrium </ standard>

<Brand> tower palace </ brand>

</ Place>

At this time, if the tag is stored in a format such as xml, meta information such as <property name> or </ property name> is required, but if it is stored as a field of a DB, <property name> or </ property name > The same thing may not be necessary. In this case, the above tags may be as follows.

1) Bed, coffee, tower palace (when completing tag field only by product name)

2) Ace bed, Starbucks coffee, Dogok-dong Tower Palace (to complete the tag field, including the brand name)

Of course, the above 1) to 2) may be mixed to generate at least one or more commercial tags. Since the DB fields are one kind, they can be stored as commercial tags without distinguishing places or props. However, if they can be divided into place fields, prop fields, and related product fields, It will be apparent to those skilled in the art that field values may be entered.

Hereinafter, a description will be given of the formation of a tag set by adding meta information such as <property name> or </ property name>, but a method without such meta information is naturally included in the inventive concept.

In this case, the meta information acquisition module 5100 may obtain only prop name or place name information as name information of a product, a place or a service, but may further obtain other information related to the prop such as brand information or standard information. Could be.

Before describing time-dependent commercial tags, let's first describe how subtitle files work in movies and the like. Normally, subtitle files can be in other file formats, but they are often in the smi file format. In the present invention, the smi file will be described as an example, but it will be understood that the inventive concept is not limited to the smi file format. The smi file generally includes a specific subtitle and time zone information in which the subtitle should appear. E.g,

<SYNC Start = 3103038> <P Class = ENCC>

My Starbucks is ready.

<SYNC Start = 3125091> <P Class = ENCC> &nbsp;

In this case, SYNC Start = 3103038 means that there is a subtitle "My Starbucks is ready." Between 3103038 milliseconds and 3125091 milliseconds. Most video players can recognize the subtitle file format, and can expose a specific subtitle set at a specific time zone to a specific position on the screen of the video. In countries such as the United States, it is mandatory for the hearing impaired to input subtitle information corresponding to audio information of a video medium such as a movie or news. In this case, the subtitle “My Starbucks is ready.” Is displayed between 3103038 milliseconds and 3125091 milliseconds as SYNC Start = 3103038, and if a subtitle (caption) is to be displayed for the hearing impaired person, the time interval is displayed. This means that what should be shown in is optimal. In Korea, TV news can be viewed as a video on sites operated by broadcasting stations, such as www.mbc.co.kr. When these news videos are streamed, there are often lines or subtitle information next to them.

Therefore, the time-dependent commercial tag introduced in the present invention further includes information about the commercial tag and a specific time point or time zone to which the tags are related.

For example, assuming a scene where a heroine man and woman wake up in the morning on a king-size ace bed with a background of a Dogok-dong Tower Palace 45-flat apartment at a specific point in time, the time-dependent commercial tag may have the following structure. Could be. The time dependent commercial tag of the present invention refers to a tag including start time information and end time information on which a specific time independent commercial tag should be displayed. For convenience of explanation, the description is given in the SMI file format, but the interpretation of the time dependent commercial tag is a problem of an interpreter and may be independent of the interpretation of a conventional SMI file. That is, a typical video player recognizes a smi file format having the same file name as a video as a subtitle file of its own video. The extension of the file associated with the time dependent commercial tag may be smi, but may be another extension (eg .xyz). If the smi file extension is used, and the smi file interpreter is the usual one, the << tag name> "or" </ tag name> as well as the contents will be recognized and expressed as characters. In this case, the <property name> bed </ Only "bed" should be inserted, not prop name>.

Interpreting time-dependent commercial tags such as the example above, it can be seen that the image between 3103038 milliseconds and 3125091 milliseconds is associated with a king-size ace bed and a 45-square doggok tower palace. Of course, at this time, the time-dependent commercial tag is followed by a string having a <> mark instead of a normal subtitle after the start time information, so it is natural that this information is processed differently from a normal smi file.

It shows that time zones can correspond to each of these kinds of time-dependent commercial tags. Looking at the above time zone information, it can be seen that Dogok-dong Tower Palace and the bed is in the same time zone, Starbucks coffee is in a different time zone.

That is, the time-dependent commercial tag of the present invention is characterized by including 1) tag content information, 2) time zone information (for example, start time point information and end time point information). The tag content information may be a time independent commercial tag of the present invention, and the content may be related to the name of the product, place, or service as described above. The display of <SYNC Start = 3103038> <P Class = KRCC> and <SYNC Start = 3125091> <P Class = KRCC> &nbsp; is only an example of displaying time zone information, and other modes of time zone information may be sufficiently displayed. will be. For example, time zone information may be displayed for each prop tag. That is, since the information about a plurality of props and places are displayed at a specific time zone, the props or places may not always be exposed at the same time. Therefore, time-dependent commercial tags may be generated in individual prop units, time zone information in an individual place unit, or the preset time zone information display method. For example:

In this case, the metadata information acquisition module 5100 obtains the time dependent commercial tag between 3103038 milliseconds and 3125091 milliseconds, and the keyword advertisement control module 6900 of the present invention preferably stores the time during the time. It would be desirable to process dependent commercial tags to expose the obtained keyword advertising content to the user. If there is no keyword ad content corresponding to the time-dependent commercial tag associated with a particular time zone (e.g., between 3103038 milliseconds and 3125091 milliseconds), then one or more time zones selected before or after that time zone are selected. It may also expose keyword ad content using time-dependent commercial tags. If it's in the previous time zone, you can keep the keyword ad content unchanged. If it's in the later time zone, you can pull out the keyword ad content first and then relate to the time-dependent commercial tags in the time zone before the time zone screen appears. will be. The reason why it is possible to pull out first is because the broadcast video is normally buffered, and thus the video image exposed at a specific point in time is obtained before a certain time.

Such a time-dependent commercial tag may be associated with at least one broadcast video.

There may be a case where there are a plurality of keyword ad target text candidates in the one time dependent commercial tag. For example, in the prop, a king-size ace bed and Starbucks coffee appear at the same time. As described above, the case where there are a plurality of keyword advertisement target text candidates may be treated similarly to the case where a plurality of tags are combined in one video. This has been described in the case of the plurality of tags for the ID 3 multimedia content, "refill ink, genuine ink, infinite ink, printer, multifunction printer, ink". A time-dependent commercial tag is associated with a particular time zone, and if the image appearing at that particular time zone is treated as a single video, a plurality of keyword advertised text candidates in the time-dependent commercial tag associated with the video (in this case a king size ace bed) And Starbucks Coffee, Dogok-dong Tower Palace, etc.) may be applied to the inventions described in the case of the plurality of tags for the ID 3 multimedia content, "refill ink, genuine ink, infinite ink, printer, multifunction printer, ink". That is, one broadcast video may be treated as a set of m moving pictures in a time zone unit, and the time zone unit may be processed as start time information and end time information included in a time-dependent commercial tag.

Caption recognition,

And, if there are n time-dependent commercial tags included in the one broadcast video, after audio and video of the broadcast video is finished, only a specific field (eg prop fields) among the n time-dependent commercial tags is collected. When the user selects a specific field, the user may process the time-dependent commercial tag related to the selected field value, obtain keyword advertisement content, and transmit the same to the user.

Meanwhile, the multimedia content service system 1000 (the person who transmits the broadcast video to the broadcasting station or other user's computer which provides the broadcast video may be the multimedia content service system 1000). A time-dependent commercial tag storage interface in a predetermined icon / form / button / selection box format can be provided on a screen including a broadcast video. For example, if a button showing the message “Save tag related to the scene” is displayed at a corner of a broadcast video screen, and there is a click on the button from the user's computer, the time-dependent time of the click occurs. You will be able to store commercial tags. And when there is a call to the time dependent commercial tag information from the user's computer after the audiovisual of the broadcast video is finished or during audiovisual or pause, the specific field of the time dependent commercial tag or the time dependent commercial tag Relevant keyword advertising content can be obtained and exposed to the user's computer. Of course, in this case, if there is advertisement / promotional content such as advertisement / promotional image or advertisement / promotional image related to the time dependent commercial tag, the advertisement / promotional content may be transmitted to the user's computer. On the other hand, if the user's computer is an IPTV, the pointing device for the IPTV is a remote control, etc., and the user cannot conveniently move the specific button on the screen of the IPTV of the remote control, the message is “To save the tag related to this scene. Press the aaa button. ” That is, the remote controller is easy to press the specific button promised. Of course, if you have a remote with a gyro function (the remote control has a gyro sensor, the movement of the remote control can be displayed on the IPTV screen), or even if the other pointing functions are good, the remote control can press the promised button. It would be more desirable to. Of course, it will be obvious to those skilled in the art that the message may be a more intuitive message such as "Press aaa to see props related to this scene."

Meanwhile, at the preset time point immediately after the end of the broadcast video, a user may view keyword ad content related to at least one time-dependent commercial tag among at least one time-dependent commercial tag or at least one predetermined time-dependent commercial tag set by a broadcaster or other entity. You can also transfer it to your computer.

At least one time-dependent commercial tag set may be allocated to one broadcast video. The time-dependent commercial tag set refers to a set having n time-dependent commercial tags for one broadcast video as an element. In general, the longer the screening time of a particular broadcast video, the more scenes, the more props and places appear, the more scene transitions, and the more names of goods, places, or services in the dialogue, the larger the number n will be. And, when one broadcast video is given, m time-dependent commercial tag sets may be generated by independent independent subjects, and a specific time-dependent commercial tag set may be selected according to a broadcaster or a user's selection. In this case, the multimedia content service system 1000 for providing a specific broadcast video may receive a time-dependent commercial tag set for the specific broadcast video from an internal or at least one or more external computers. In this case, when the multimedia content service system 1000 streams or transmits the specific broadcast video, the multimedia content service system 1000 transmits the received time-dependent commercial tag set in sync, or transmits it to the user's computer. A player (an application that can play video) installed on a computer can be synchronized with the video to output a set of time-dependent commercial tags received to the user's computer. As described above, each time-dependent commercial tag constituting the time-dependent commercial tag set includes time information and a time-dependent commercial tag set.

On the other hand, the time-dependent commercial tags may have a more simple form, such as "time information + tag content". In addition, the method of displaying time information is not only a matter of matching with an interpreter interpreting the displayed method, but may be in various forms as well as the smi file format.

For example, when there is a time dependent commercial tag in the form of "start time + tag content + end time", it indicates that the tag content is related between the start time and the end time. For example, it might look like this:

1) <SYNC Start = 3105092> <P Class = KRCC> Starbucks <SYNC Start = 3305091> <P Class = KRCC> &nbsp;

2) <SYNC Start = 3105092> Starbucks <SYNC Start = 3305091> &nbsp;

3) <SYNC Start = 3305091> Starbucks <SYNC End = 3305091>

4) <SYNC Start = 3105092> Starbucks; coffee; Tower palace; Ace bed <SYNC Start = 3305091> &nbsp;

5) <Start = 3105092> Starbucks <SYNC End = 3305091>

1) to 5) above are just examples. 1) shows an example of a method of displaying tag information in a conventional smi file representation format, 2) shows an example without a language display portion, and 3) displays start and end points. 4) may include a plurality of tag contents; in 5) a sync (sync) identifier, such as “<Sync Start”, in which any form of identification “<Start It introduces the introduction of arbitrary promised forms such as

For example, the following n time-dependent commercial tags may be associated with a specific video # 1 having a play time of 10 minutes. The format of time-dependent commercial tags is 4) for convenience of description.

<SYNC Start = 000001> Starbucks; Coffee <SYNC Start = 120000> &nbsp;

Tower Palace; ZIA APART <SYNC Start = 180000> &nbsp;

Ace Bed <SYNC Start = 180001>; Dunlop pillow; Bed cover <SYNC Start = 3000000> &nbsp;

<SYNC Start = 300001> Haptic cell phone; Photo shoot; Ringtone <SYNC Start = 500000> &nbsp;

<SYNC Start = 500001> <SYNC Start = 600000> &nbsp;

The top one is “Starbucks; Coffee ”, the second is Tower Palace for 120 to 180 seconds; It can be seen that the content of the tag called gia apat is associated with the video # 1. On the other hand, no tag content may be allowed in a specific time zone, such as no tag content between 500 and 600 seconds.

The one or more time-dependent commercial tags as described above may be input by the operator of the operator of the multimedia content service system 1000 that serves the video or the operator of the operator of the multimedia content service system 1000, and then stored in advance. In addition, the producer and distributor of the video may be stored. Furthermore, a time-dependent commercial tag related to the specific point in time or a time zone including a specific point in time is received from the computer of the audiovisual person who is certified or independent of the authentication, and is stored with the video. When selected by the user of, the inputted time dependent commercial tag may be used to transmit keyword advertising content associated with the time dependent commercial tag to the third user's computer. In this case, information about a predetermined monetary or non-monetary compensation (for example, providing 1% of the generated advertising fee) may be provided to a computer of an authorized person who has entered the time-dependent commercial tag. In this case, when there are n time-dependent commercial tag inputters for a specific video # 1, the operator of the multimedia content service system 1000 may set two or more time-dependent commercial tag sets for each time-dependent commercial tag set. After applying to the present invention by selecting the, it will be possible to select at least one or more time-dependent commercial tag set that is ranked at the top or the top by a predetermined criterion such as the total number of clicks generated, the total amount of advertising revenue generated. In this case, when the video # 1 is selected by the third users, the multimedia content service system 1000 displays the keyword advertisement content using the selected time-dependent commercial tag set of the third user. You can transfer it to your computer.

There is a need to synchronize with the playback of the video and keyword advertising content utilizing the time dependent commercial tags constituting the time dependent commercial tag set. That is, when a specific point in time or a section of a video appears on a user's computer (either streaming or file downloading), the keyword advertising content associated with the time-dependent commercial tag corresponding to the specific point in time or a specific section needs to be provided to the user's computer. Therefore, the synchronization may play an important role in content matching. The method for synchronization is the same as or equivalent to that described above for synchronization between the playback of the multimedia content described above and the provision of keyword advertising content based on text obtained from the multimedia content. The synchronization of the present invention will be fully understood if the text obtained above corresponds to text contained in a time dependent commercial tag. On the other hand, when there is a plurality of time-dependent commercial tag information at a specific point in time or a specific section, which tag information is used to transmit which keyword advertisement content to the user's computer may be the same as or similar to that described above when there is a plurality of tag information. will be. On the other hand, if there is a caption in the video, it is natural that the caption and the time-dependent commercial tag of the present invention are processed independently in the multimedia content service system 1000 or the user's computer. If the extension is different, it will be more natural.

Generate a commercial tag set

Meanwhile, the multimedia content service system 1000 may generate meta tag information included in the multimedia content service system 1000 by processing meta information included in the multimedia content. The multimedia content service system 1000 generated tag information may include 1) the multimedia content service system 1000 in a manner equivalent to a method of generating a keyword advertisement target text from the title or description information obtained by the multimedia content service system 1000. The generation tag information may be generated and stored, and 2) the time dependent commercial tag may be generated and stored from text information obtained from subtitles or speech recognition. The method of 1) has been described, and the method of 2) will be described in more detail. The multimedia content service system 1000, when the caption has start time information and end time information to which the subtitle and a specific subtitle are to be exposed, such as in a smi file format, the keyword advertisement target text from the subtitle as described above. Alternatively, a tag is generated, and the generated keyword advertisement target text or tag is stored together with start time information and end time information of the subtitle to which the subtitle is exposed. In the case of speech recognition, since the start time information and the end time information are not shown, 1) other preset time units such as 1 minute, 2) a predetermined number of tags or keyword advertisement texts such as 1 or 3 The time may be divided evenly or unequally, such as a time unit generated.

In this case, when there is multimedia content such as the specific video, attaching a commercial tag to the multimedia content may be implemented systemically, and performing such a function is called a commercial tag set generation system 10000. The configuration of the commercial tag set generating system 10000 is shown in FIG. 27 illustrates a configuration of a commercial tag set generation system 10000 corresponding to a non-development model, but the commercial tag set generation system 10000 is centered on a mediation model or a keyword advertisement content providing system 3000. Of course, it can also be applied to the model. It can be seen that the meta information acquisition module 5100 includes a commercial tag set acquisition module 5140 that obtains a commercial tag set, which is a collection of one or more commercial tags generated and transmitted by the commercial tag set generation system 10000. have. The following description will focus on the non-dispersion model.

First, the relationship between the multimedia content service system 1000 and the commercial tag set generation system 10000 will be described. The commercial tag set generation system 10000 may be operated by the same operating entity as the multimedia content service system 1000 or may be operated by a separate operating entity. In addition, the commercial tag set generation system 10000 may be structurally included in the multimedia content service system 1000, and may be included in a separate system independent of a wired / wireless network. The commercial tag set generation system 10000 receives the multimedia content from the multimedia content service system 1000 through file download or streaming, and then forms a commercial tag set for the multimedia content, and generates the commercial tag set. And store the commercial tag set to the multimedia content service system 1000 through the commercial tag set transmitting module 12000. The commercial tag set acquisition module 5140 of the meta information acquisition module 5100 of the multimedia content service system 1000 stores the transmitted commercial tag set in association with the multimedia content. The meta information acquisition module 5100 may treat the received commercial tag set in the same manner as the tag information obtained by the tag information acquisition module 5110. Meanwhile, although the keyword advertisement target text generation module 6510 may treat the commercial tag set obtained by the commercial tag set acquisition module 5140 with the tag information obtained by the tag information acquisition module 5110, both If they coexist, they can be treated with higher priority or weight. In this case, it will be obvious that the multimedia content is managed by an identifier (id) for identifying the multimedia content.

The commercial tag set generating system 10000 includes a commercial tag set generating server (not shown), and the commercial tag set generating server (not shown) includes a commercial tag set generating module 11000 and a commercial tag set transmitting module ( 12000). There are three ways in which the commercial tag set generating module 11000 generates a commercial tag set. The first is a method for creating an audio-visual content by an expert, and the responsible person is responsible for this. The second is a system for generating a commercial tag set. The second is a method for generating a system systematically. Module 11400, and the third method is a method of generating through participation of an unspecified number of users, and the user is responsible for the user's participation in generating a commercial tag set module (commercial tag set obtaining module 5140) 11300. Split in order.

The expert-selected commercial tag set generation module 11200 is in charge of a method for generating a commercial tag set by an expert intervening in a specific multimedia content. The expert-selected commercial tag set generation module 11200 provides multimedia content information received or transmitted from the multimedia content service system 1000 by the multimedia content acquisition module 11100 to the expert's computer, Obtain and store at least one or more time independent commercial tags or at least one or more time dependent commercial tags from a computer. The multimedia content acquisition module 11100 may not be an essential component of the commercial tag set generation module 11000, but is preferably present. For example, when generating time-independent commercial tags for a specific multimedia content, it is not necessary to add time information to the generated commercial tags, and only a commercial tag set corresponding to the entire multimedia content is generated.

A manner in which the operator of the multimedia content service system 1000 or a business associate of the multimedia content service system 1000 downloads and plays the multimedia content with respect to at least one or more multimedia contents having a particularly high hit number or a play method in a web browser. While visually viewing the multimedia content, etc., a commercial tag input module 11210 for inputting a time independent commercial tag for the multimedia content is displayed on a monitor, and a time independent commercial tag for the multimedia content is placed on the multimedia content. You can enter about. In this case, the commercial tag input module 1210 may include a multimedia content ID display unit 11211 and a multimedia content player 11212 capable of audiovisual viewing (playing multimedia content streamed by a built-in browser or downloading a file). Multimedia content player 11212 capable of playing multimedia content), and multimedia information meta information display unit 1112 where meta information (title, tag, description, author ID, number of hits, etc.) related to the multimedia content can be displayed together. It is preferable to include). On the other hand, the commercial tag input module (11210) preferably has a commercial tag input unit (11213) for inputting a commercial tag or a commercial tag set display unit (11214) for displaying the obtained commercial tag set, the input or received commercial It is preferable to further include a commercial tag verification unit 1151 for verifying the commerciality of the tag. The commercial tag verification unit 1215 queries the keyword for the commercial tag and / or the keyword advertisement content providing server-side advertisement keyword DB 3140 of the keyword advertisement content providing system 3000 for the commercial tag. Verify the tag's commerciality. In order for the latter verification to be established, external access to a part or all of the keyword advertisement content providing server-side advertisement keyword DB 3140 is allowed, such as by opening the API of the keyword advertisement content providing system 3000. Of course it should.

The above attributes 1) to 18) of the advertisement keyword DB 6657 or the keyword advertisement content providing server-side advertisement keyword DB 3140 for a specific advertisement keyword are as described above. The validity of the commercial tag is verified based on information on how many of the attributes 1) to 18) are satisfied as the advertisement keywords for the commercial tag, and information on the weight function and / or the score function for each attribute. You can do it. The commercial tag verification unit 1151 may 1) calculate 1) to 18) and / or the score function value for one commercial tag selected, or 2) 1) to n commercial tags selected. 18) and / or calculate a score function to assign a sequence to each criterion or to a predetermined formula (eg, a specific score function). That is, the operator or the business associate of the multimedia content service system 1000 selects a tag candidate for the selected specific multimedia content and passes the commercial tag verification unit 1215 to the rear part of the tag to set a predetermined condition ( For example, only the tags that passed 1) to 18) or the criterion for a specific score function value) may be finally selected. At this time, of course, specific tags may be listed in a commercial tag set without passing through the commercial tag verification unit 1151, and some experts may use commercial or commercial methods without experience with the commercial tag verification unit 1215. It may form a set of tags. At this time, one example of the other method is to query the tag candidates with a keyword advertising content providing system 3000 such as a search engine (www.naver.com or google.com) or overture.com, and then the tag candidates. It can be made by inquiring whether the keyword advertising content exists and the degree of advertisers or advertising bids. In the case of search engines, this can be determined by the presence of data values in the Sponsored Links area, and www.overture.com also indicates that there is an advertiser competition information (such as bid information-bid information) for a particular keyword. This means that you can use this method as a simple verification method because it has a lot of advertisers and competition for ad serving.) A time independent commercial tag set is generated for one multimedia content specified as above, which is performed by the time independent commercial tag generating unit 1112 of the present invention.

In the above, a time independent commercial tag has been described, followed by a time dependent commercial tag. In order for the time-dependent commercial tag generation unit 11217 of the present invention to generate a tag set relating to the time-dependent commercial tag, each commercial tag should include time information related to the reproduction of the multimedia content. To this end, the expert's computer or the commercial tag set generation module 11000 should include 1) a play function module, 2) a time display / section display module, and 3) a tag corresponding module for the section of the multimedia content. do. The function of the time display / section display module may be able to designate a section between a specific frame / time point and a specific frame / time point of the multimedia content and display a time corresponding to the designated section. That is, the time-dependent commercial tag generation unit 11217 is a commercial tag from the commercial tag and the section / time information when the operator or the business associate designates a section, and at least one commercial tag for the designated section A function for generating a time dependent commercial tag of the present invention including information and time information (start time information and end time information associated with the commercial tag) is performed. In this case, the time-dependent commercial tag generation unit 11217 may generate a time-dependent commercial tag set for only tags that are higher than or equal to a predetermined criterion by passing the commercial tag verification unit for the received tag candidates.

Meanwhile, since the time-dependent commercial tag generated by the time-dependent commercial tag generation unit 11217 includes time zone information, the following problem situation does not occur in the time-dependent commercial tag. The first is the question of what policy to implement if the commerciality of a commercial tag obtained at a specific time zone falls below the previous or later time zone. Second, there is no commercial tag obtained at a specific time period, or the number of keyword advertisement contents obtained from the advertisement keyword DB 6657 related thereto even if there is a commercial tag. Third, the time dependent commercial tag set is completely different depending on how the time zone is divided. These three problems are not a big problem for time independent commercial tag generation.

There are three methods for mapping at least one time-dependent commercial tag set having one or more time zones separated from specific multimedia contents, particularly broadcasting multimedia contents having a relatively long play time.

In the first method, a commercial tag set for a specific time period is searched in the advertising keyword DB 6657 and the keyword advertising control policy DB. Then, if the search result corresponds to the first or second problem, 1) the predetermined criteria is achieved. If not, a method of performing keyword advertising by using a commercial tag set of a time zone before or after a specific time zone, and 2) mixing a set of commercial tags for a time zone or a time zone before and a commercial tag set for the specific time zone. Thereby, there will be a method of forming a mixed commercial tag set and performing keyword advertising according to the present invention with the mixed commercial tag set.

In the second method, when the scene number information of a specific video is known, a certain portion of the video corresponding to the specific scene number is treated as one unit based on the scene number, and a time-dependent commercial tag set is processed in that unit. There is a way to create it. In this case, the time-dependent commercial tag set has the greatest unity with the scene considered by the author of the video.

The third method is to extract a tag up to the most common n or the most common tag among the tags belonging to the commercial tag set of the at least two time zones, and to identify the first and second problems with the extracted most frequently used tags. Complementing a set of commercial tags related to time zones, and performing the keyword advertising method of the present invention for the particular time zone with the supplemented commercial tag set.

On the other hand, props worn by the protagonist (watches, jewelry, earrings, costumes, etc.) are common in various time zones or scenes. In this case, it is a problem of how to process commercial tag sets related to the commonly-produced prop. The frequent props typically have a higher frequency among commercial tag sets. The high frequency commercial tags may be used 1) to continuously provide related keyword advertising content throughout the entire time zone, and 2) to display the relevant keyword advertising content when the video is finished playing. Grouping by tag (provide the most frequent commercial tags, list the extracted tags, and obtain and provide a preset number of keyword ad content for each of the most common commercial tags listed). 3) Commercial A method of intensively replenishing a tag at a specific time period where the commerciality of the tag is weak may be utilized.

Such a commercial tag set may be stored and managed separately from a normal UCC tag set or a management tag set. Meanwhile, when the video is provided, the commercial tag set may not be provided to a user's computer. However, the commercial tag set may satisfy the user's information needs. will be. When providing a commercial tag to a user's computer, when click information on the commercial tag is obtained, the commercial tag is searched for a video sharing the commercial tag as a commercial tag, or processed like a normal tag. , The commercial tag may be provided as a tag, or a video included in other meta information such as title or description information may be provided as a search result.

The expert-selected commercial tag set generation module is specifically designed for: 1) UCC videos with high hits, 2) Dramas, news, documentaries, sitcoms, show programs, travel, restaurants, products, services or places, etc. 3) movie videos such as sex programs, and 3) movie videos (extracting text for keyword advertising from subtitles or voice information is excluded from this paragraph, as described in the Systematic Commercial Tag Set Generation Module). There will be. Of course, the user uploading the UCC video may provide a time independent commercial tag or a time dependent commercial tag with respect to the UCC video. In this case, the multimedia content service system 1000 for uploading the UCC video may be provided. It should include the ability to provide commercial tags independently of the usual tag information fields. In particular, in order for a user to input a time-dependent commercial tag, the user must provide a function that can correspond to time information for each time-dependent tag. For example, “time information field (start time field, end time field) vs. One or more commercial tag fields ”. In particular, in the case of UCC video with a high number of hits, it is preferable that an operator of the multimedia content service system 1000 inputs a time-dependent commercial tag or a time-independent commercial tag. In the case of a broadcast video, the operator of a broadcasting station or the producer of the broadcast video, It would be desirable for editors or their entrusted experts to enter dependent or time-independent commercial tags.

Of course, even in the case of live broadcast, it will be obvious that the present invention can be applied even when the live broadcast is transmitted to the user's computer (including IPTV). That is, the operator of the multimedia content service system 1000 (the system of the broadcasting station or cable TV provider or the live broadcaster or intermediary corresponds to the multimedia content service system 1000 of the present invention) with respect to the transmitted broadcast video. A person who is entrusted by the operator may input at least one commercial tag in real time to the commercial tag input module 1210 with respect to the live broadcast image, and the tag input in real time forms a time-dependent tag set. . In this case, it will be obvious that the input commercial tag may go through the commercial tag verification unit 1151. The input commercial tag is treated like the time dependent commercial tag of the present invention, and the present invention described above is applied as it is. However, in this case, the time zone unit to which the time-dependent tag set corresponds may be a unit designated by the real-time commercial tag inputter. On the other hand, when only one commercial tag is input or processed in a tag set unit, until the next input of one tag or the next tag set unit is provided to the commercial tag input module 1210. May be a time zone corresponding to the one tag or the tag set unit.

Entering a commercial tag for a particular video can be open for a specific group of users as well as for an unspecified number of users. When a plurality of users participate in the commercial tag input, a time-dependent commercial tag set or a time-dependent tag set for each user is generated in a specific video. In this case, the commercial tag set generating module 11000 passes the tag set for each user through the commercial tag verifying unit 1115 for the keyword advertisement control policy DB 6640 such as 1) to 18) or a score function. ) Will be able to choose from a set of commercial tags for a specific user that are optimal for the conditions presented by). On the other hand, if there is scene information in the video, or if the division of time zone of the video is given by the commercial tag set generation module 11000, a commercial tag set of another user is provided in the scene information unit or in the time zone division unit. Catering may be chosen. Of course, at this time, information about a preset reward may be transmitted to the user's computer.

Then, it changes the commercial tag set used over time and accumulates keyword advertising effects (total clicks, total ad revenue, etc.) for each commercial tag set over time, The analysis can be refined into a set of commercial tags with high keyword advertising effectiveness. This is even more necessary in the case of time-dependent tag sets.

Next, the systemic commercial tag set generation module will be described. The function performed by the system commercial tag set generation module 11400 is the same as that described in the process of generating the keyword advertisement target text by the keyword advertisement target text generation module 6510 using the text information obtained by the non-tag text acquisition module. Functionally equivalent. However, the systemic commercial tag set generation module 11400 may exist outside the multimedia content service system 1000, and text obtained by the non-tag text acquisition module 5130 of the multimedia content service system 1000 may be obtained. The information may be received to generate a time independent commercial tag or a time dependent commercial tag from the text information. In particular, when the multimedia content service system 1000 provides a captioned video such as a movie or news, the caption information is obtained and processed (morphological analysis, name extraction of goods or services, madness keyword DB, etc.). Pass through a commercial tag verification module, including filtering through, etc.) to generate a time independent commercial tag or a time dependent commercial tag of the present invention, and transmit the result to the multimedia content service system 1000 through the commercial tag set transmission module 12000. Will be able to transmit.

28 is a diagram of an embodiment of a commercial tag set generation module 11000 of the present invention. The commercial tag set generation module 11000 is included in the commercial tag set generation system 10000 so that an expert who generates a commercial tag or a user who participates in the generation of a commercial tag accesses the commercial tag set generation system 10000. (Of course, various functions are configured in the form of JavaScript and executed in a browser, of course), or can be used in a manner that is downloaded from the commercial tag set generating system 10000 and installed on the user's computer. will be.

As can be seen in FIG. 28, the commercial tag set generation module 11000 has a video acquisition unit 11100. When the search button is pressed, the commercial tag set generation module 11000 searches for a video received from the multimedia content service system 1000 or the multimedia content service. It is possible to access the system 1000 to obtain video information. Of course, by inputting a URL, URI, or universal content identifier (UCI), it is possible to obtain desired video information.

The commercial tag set generating module 11000 includes the commercial tag input module 1210, and the commercial tag input module 1112 generates a user-participating commercial tag set as well as an expert-selected commercial tag set generating module 11200. It will be obvious that the module 11300 may also be included. The expert-selected commercial tag set generation module 11200 of the commercial tag set generation module 11000 includes a multimedia content ID display unit 11111. In the drawing, the video tag information is included and preferably includes a video ID. Meanwhile, the multimedia content meta information display unit 1112 includes a title, a tag, a description, and the like of the video. Since the description is generally long, it is preferable to appear when the description button is pressed.

In order to quickly attach a commercial tag to a video or the like, it is preferable to include a multimedia content player 11212 in the commercial tag set generating module 11000. In this case, the multimedia content player 11212 is played. The advantage is that you can easily enter commercial tags while watching a video. On the other hand, it is preferable that there is further a time selector for selecting two time / times (starting time, end time) for inputting a time-dependent commercial tag under the multimedia content player 1112. Preferably, the time selector appears only when time dependent tag generation is selected in the selection of a commercial tag type. An expert or a participant or an operator of the multimedia content service system 1000 enters a commercial tag in the commercial tag input unit 1112, performs verification on the commercial tag, and then presses an input button. Do. The verification is preferably performed by the commercial tag verification unit 1215, and the verification may be performed when the commercial tag is input to the commercial tag input unit 1113, but all of the at least one set of commercial tags listed in the commercial tag list Alternatively, verification may be performed on the selected part. Although batch verification may be performed on one or some or all of the selected commercial tag lists (candidates), selective verification may be performed. Of course, if the validation option button is pressed, a criterion for verification (1 to 18 for the advertising keyword, a score function, a difference function, etc.) is presented, and the criteria may be selected, based on the selected criterion. The verification is performed, and the results of the verification may include 1) whether to include in the verified commercial tag list and ranking (sequence) information of the commercial tag list based on the selected criteria. The commercial tag set display unit 1214 may be divided into a commercial tag list candidate and a verified commercial tag list unit. However, only one commercial tag list candidate may be used to implement the inventive concept.

In addition, when the time dependent commercial tag generating unit 1112 functions, various commercial tags of the commercial tag list may include time zone information (start time information and end time information) corresponding to the commercial tag. When the user selects time-dependent tag generation (it may be selected by default, or may be the only one), and when selecting / inputting time zone information, when the commercial tag is input through the commercial tag input unit 1213, the commercial tag is input. The time dependent commercial tag generation unit 1112 maps / synchronizes and stores the commercial tag with the selected / input time zone information.

Of course, in the case of the time-dependent commercial tag generation unit 1217, time zone information will not be necessary. Any one of the multimedia content service system 1000, the meta information-based keyword advertisement mediation system 2000, or the keyword advertisement content providing system 3000 may include a time dependent commercial tag including the playback of the video and the time zone information. It may be desirable to synchronize the display of the keyword advertisement target text so that the keyword advertisement target text is displayed on the user's computer. On the other hand, when the transmission button is pressed, the commercial tag set transmission module 12000 is operated to transfer the generated commercial tag set to the multimedia content service system 1000 or the meta information based keyword advertisement mediation system 2000 or the keyword. Any one or more of the advertisement content providing system 3000 may be transmitted to a predetermined server.

The commercial tag set generation system 10000 may be included in the multimedia content service system 1000 or may be connected to the multimedia content service system 1000 through a wired or wireless network.

Referring to FIG. 30, an embodiment in which the multimedia content service system 1000 implements the inventive concept using the commercial tag set generation system 10000 will be described.

The multimedia content service system 1000 includes a multimedia content service server that plays a video selected by a user and transmits the played video information to the user computer 9000. 10000) transmitting the video information (S91); Receiving a commercial tag set corresponding to the video information from the commercial tag set generating system 10000 (S92); Storing the commercial tag set in correspondence with the video (S93); Acquiring selection information about a video to be transmitted from the user computer 9000 to the user computer 9000 (S94); Receiving keyword ad content corresponding to at least one commercial tag included in the commercial tag set (S95); And transmitting the video and the keyword advertisement content to the user computer 9000 (S96). The advertisement method of the present invention may be performed. The commercial tag set may include at least one time-dependent commercial tag, and the time-dependent commercial tag may include time information in information constituting the tag.

The time information includes two viewpoint information, and the two viewpoint information is start time information and end time information. The keyword advertisement content corresponding to the time dependent commercial tag is preferably displayed between the two viewpoint information associated with the video when the video is played.

Change search results ranking

Subsequently, in general, multimedia content is exposed to a user primarily when a user inputs a search word or clicks on a user's tag, etc., a search engine or multimedia constructed with multimedia content data using a search word or a tag as a search keyword. The query is made to the DBMS about the content data, and the outputting is made to satisfy the query result. The user selects the multimedia content by clicking on the output multimedia content search result. In this case, the total number of multimedia contents, the multimedia contents exposed on the first page, and the same page are exposed according to a predetermined weight or ranking policy selected by a user who manages a large number of user clicks or other multimedia contents DB 1110. The ranking among the multimedia contents is determined.

In this case, in order to maximize the profit of the multimedia content service system 1000, the meta information-based keyword advertisement mediation system 2000, or the keyword advertisement content providing system 3000, 1) a multimedia content in which a click occurs in the keyword advertisement content, 2) multimedia content that generates clicks on keyword ad content with high unit prices, and 3) multimedia content related to keyword ad content with high click-through rates. The reason is that users typically select multimedia content arranged in front of the first page. Therefore, when the multimedia content having high expected profitability is placed in the ranking / order / location / page where the user is likely to select, the user selects the multimedia content to be audiovisual and then the audiovisual is finished or after the audiovisual is over. Keyword advertising content exposed to a predetermined position is also more likely to click. On the other hand, when a plurality of keyword advertising content is exposed, presenting the keyword advertising content with a high click-through rate or a high expected rate of return based on existing users to the user will likely generate advertising revenue.

To this end, for each specific multimedia content, 1) the keyword advertising content identifier that generated the click, 2) the keyword advertising text or keyword advertising text group that generated the click, the specific keyword advertising text or the keyword advertising text group, or the specific multimedia content 3) total clicks, 4) total ad revenue, 5) clickthrough rate relative to keyword ad content impressions, 6) average revenue relative to keyword ad content impressions, and 7) estimated clickthrough rate relative to keyword ad content impressions. (This 7) may be the same value as 5)), 8) one or more of the estimated revenue (key 8) may be the same as 6) relative to the keyword ad content exposure. An estimated revenue for each specific multimedia content can be calculated by processing any one or more of 1) to 8) as a variable using a preset revenue contribution function. For example, the revenue contribution function for a particular multimedia content i, f (i) = the total ad revenue for the keyword ad content for a particular keyword ad target text j of i, or f (i) = the impression ratio of i The total number of clicks related to i or f (i) = sum (advertising unit price * click-to-exposure rate of keyword ad content jk for a specific keyword ad target text j of i). sum means sum. When the multimedia content i is calculated using the revenue contribution function as described above, when there are multimedia content search results satisfying the same search word input or the same tag, the multimedia content having the highest revenue contribution function value is first exposed as a search result. Or at least a revenue contribution function value may be used to determine the exposure order / location / ranking / page of the multimedia contents. That is, for the same search keywords, 1) preferentially expose high-precision multimedia contents as search results, and 2) search results with low weights (usually field weights, if the search keywords match in the title, The weight may be high and the weight may be relatively low if the description matches.) Even if there is multimedia content that matches the search term in the field, if the expected profit of the multimedia content is high, the priority of the exposure is reflected to reflect the degree of profitability. You can adjust the ranking.

Calculating the expected revenue for a particular multimedia content i and determining the order of exposure of the multimedia content based on the expected revenue once again demonstrates that the inventive idea is essentially different from a typical search keyword advertisement. That is, a normal search keyword advertisement only has a connection to a specific content and input of a search word, and thus cannot accumulate an advertisement effect generated under the specific content. The reason is that since the keyword advertising contents are placed on a page equal to the specific content as a search result in the normal search keyword advertisement, it is difficult for the keyword advertising content to set a revenue contribution function with the specific content.

The present invention can be utilized in the wired / wireless online advertising industry, multimedia content industry, information and communication service industry, video industry such as movies, image industry, music industry, sound industry, and the like.
