Description

Foot mark-based content search device by user {CONTENTS SEARCHING APPARATUS BASED ON PERSONAL FOOTMARK}

The present invention relates to a technology for providing a user-specific content search system according to a user's taste in a search engine system. More specifically, a technology that provides a user with a content search system that is more useful than an existing content search engine by referring to a user's taste or a content search history of another user having a search history of content similar to a content previously searched on the Internet. It is about.

With the development of Internet technology, research on technology for providing a service that enables a user to search for a desired content and increase accessibility of the content is also being developed. In Korea, a number of search services such as Google, Yahoo, and Naver are being implemented, and users search for contents (e.g., websites, multimedia contents, purchase items related to Internet shopping) through the service in using the Internet, Using the Internet is becoming more natural.

With the development of such Internet search technology, the amount of available content is exploding with the development of the Internet network. Currently, the amount of contents such as multimedia contents, shopping contents, information in websites, etc. is increasing day by day, and users have to search for such a huge amount of contents themselves. Compared to the limited amount of content on the Internet, the amount of content currently available to a user is increasing so that it is difficult for a user to search and use the content.

Therefore, research on the service technology that can search the contents is also emerging as an important field in the Internet-related technology. This is not to inconvenience the user by providing a huge amount of content without filtering to the user, but to provide a user-friendly Internet search service so that the user can immediately provide the desired content when searching for the content. However, since the conventional Internet search technology does not automatically set the search range according to the user, the results according to the user's query when the Internet search is vast. In this case, users have a difficult problem in searching for a desired content among the above contents due to the limitation on the use of the spatiotemporal Internet.

The user-friendly internet search service mentioned above is now implemented. A typical technique is to display contents with a high frequency of use at the time of searching for contents by giving priority to contents that users use a lot. An example of the conventional representative user friendly internet search service is shown in FIG. 1.

Referring to FIG. 1, in the conventional user-friendly internet search service, when a user inputs a search word through a terminal (S1), a search engine performs a step of extracting content including the search word (S2). Done. After the content is extracted, the search engine calculates the number of times of content search or use based on, for example, the number of clicks through the search engine of all users (S3). Subsequently, the searched contents are listed in order of the number of times of using contents (S4), and the step (S5) of providing the result to the user terminal is performed.

As mentioned above, although the conventional search engine is user-friendly, there is a problem that it is insufficient to be a truly user-friendly search service by calculating the number of times of use of all users irrelevant to the user. In addition, there is a ranking system in which a conventional search engine can prioritize materials, but the priority is not a priority that an individual user can accept, but a popular priority that can be accepted by a large number of users. . On the other hand, since the user-friendly Internet search service is premised to search with different values for each individual, the ranking system also has a problem in that a different ranking service must be provided for each user.

In order to solve this problem, what is attracting attention as a conventional search engine technology is a user-specific content search engine technology using a bookmark. Among the contents used by a user, for example, a technology that collects content information registered as a favorite used by a user, such as a favorite website, and restricts and provides a content search area based on the collected content information. According to the above technology, when the content is searched, the search result about the content registered by the user as the favorite is displayed, thereby providing the content that the user wants to find.

However, a user-specific content search engine technology using the bookmark also has many problems. In order to provide a content search to a user by using a bookmark, the range of similar content similar to the bookmark should be limited, but a technique for clarifying the range of the similarity itself is not presented. In addition, bookmark is also a content search service depending on the result of the user directly inputting the content of his or her desired content (for example, selecting a hobby or desired content when joining a site or setting a bookmark directly). Since it provides inconvenience to the user in using the user-specific content search engine technology, there is a problem that the user does not have high efficiency of use, such as feeling a skepticism about the use of the service.

In order to solve the above-mentioned problems, the present invention has an object to provide a user with content search results by setting an accurate and efficient content priority search range for each user, more specifically, the user wants to A search system that provides a search technology that does not need to be input for a range of contents, and is a search system that can be substantially implemented through accurate definition of a range of similarity in searching for existing contents similar to contents desired by a user or contents previously experienced by a user. The purpose of the present invention is to provide a user with a content search engine device desired by the user as offline.

In order to achieve the above object, the foot mark-based content search apparatus for each user according to an embodiment of the present invention, the footmark-based content search engine device for each user is connected to the user terminal via a wired or wireless communication network, Connected to the communication server for storing the footmark and collects the user's footmark (Footmark) through the communication server, the footmark collection unit for generating the footmark data by updating the collected footmark data and the communication server in real time; Receiving a user-specific foot mark from the foot mark collection unit, and searching for another user having another foot mark including one or more of the plurality of foot marks of the user at the time of user content search, the user's foot mark or the other It includes a search unit for searching by first setting the content corresponding to the user's foot mark as the search range.

According to the foot mark-based content retrieval device for each user according to an embodiment of the present invention, a content retrieval can be performed by using content search results of people whose interests are similar to those of human beings, For this reason, the concept of similarity can be clearly defined, and the accurate priority search range can be set. In addition, the user defines a natural mark as a foot mark for the content used by the user without using input (for example, inputting interest or adding a favorite) for the range of the content that the user wants to search, so that the user can use the search. There is an effect that can provide a convenient service even in the use of a convenient and Internet search engine device.

FIG. 2 is a schematic diagram of a user-based foot mark based content search apparatus according to an exemplary embodiment of the present invention. Referring to FIG.

First, the footmark is a concept used to determine priority content to be provided on a searched or searched content list of another user associated with a user required to set a content priority search object when searching for content. The foot mark basically means the footsteps of the user left in the communication network by the user searching for content or using other communication services through the user terminal. In an exemplary embodiment of the present invention, the footmark may include a history of Internet sites visited within a predetermined period (for example, six months) of each user, favorite information, search term information through a search engine within a predetermined period, content receiving history, and the Internet. It includes one or more of the product purchase history (or payment history) through. In addition, any concept that may be left by the user through the communication network and may express interest in the user's contents may be used.

Referring to FIG. 2, a foot mark-based content search apparatus for each user according to an embodiment of the present invention may be connected to the communication server 101. The communication server is connected to the user terminal 100 and the user's foot mark-based content retrieval device (hereinafter, referred to as a content retrieval device) according to an embodiment of the present invention, and the user terminal and the content retrieval device 102. It performs data transmission / reception function and storage function of each user's foot mark. More specifically, the function of receiving search term information through the user terminal 100, receiving a searched content list, and providing the content list to the user terminal 100, providing a stored user foot mark, and a foot for each user before / after searching Includes the function of updating the mark. In an embodiment of the present invention, the communication server 101 may use a generally known content search server.

In an embodiment of the present disclosure, the communication server 101 may additionally be connected to the content storage unit 105. When providing the content list among the functions of the above-mentioned communication server 101 to the user terminal 100, when there is a content providing request based on the content list of the user terminal 100, the communication server 101 stores the content. In step 105, the content to be requested may be received and provided to the user terminal 100.

The content search apparatus 102 according to an exemplary embodiment of the present invention first includes a footmark collector 103. The footmark collecting unit 103 is connected to the communication server, collects the user-specific footmarks, and performs the function of providing the collected footmarks to the search unit 104 in relation to the content search. Therefore, the communication server 101 may store a footmark for each user by constructing a database according to the user when the footmark is stored so that the footmark collecting unit 103 may collect the footmark for each user.

According to an embodiment of the present invention, when the content is finally retrieved and the user leaves a foot mark on the content in the provided content list such as the user using the content, the foot mark collecting unit 103 retrieves the new foot mark. It may further include a function of extracting from the content search results of the) to provide to the communication server 101 in real time. When providing a content list to a user, if the user is interested in any one of the provided content list, the user may use the content or leave a foot mark, and the newly generated foot mark in real time in the communication server This is because updating and storing in 101 can provide a more friendly content search to the user.

The footmark collection unit 103 may also measure the frequency of the footmarks for each user related to the search word when collecting the footmarks for each user, and generate rank data of contents related to the search word based on the frequency to communicate with the communication server 101. It may further include a function provided to. When the user searches for the content, the user's favorite content should be reflected in the search, so that the frequency of the foot mark of the user is measured and reflected as the user's preference. It is an object of the present invention to set a search range by comparing a footmark of another user with a footmark of a user and to provide a user with a content search result for the user. However, the user's preferences are also investigated to search for a desired content. You can increase the accuracy even more.

According to an embodiment of the present invention, the foot mark based content search apparatus for each user may include a search unit 104. The search unit 104 receives a user-specific foot mark from the footmark collection unit 103 when a user searches for content. Subsequently, another user having a foot mark having a similarity or more than a predetermined value to each user's foot mark is searched for, and the content corresponding to the foot mark of the user or the found other user's foot mark as a priority search range of the content searched by the user. Will be set.

In an embodiment of the present disclosure, the search unit 104 may further include an identifier for distinguishing users in order to manage information about a plurality of users and to use a foot mark by dividing by user when searching for content. .

In an embodiment of the present invention, the identifier may be an ID (identification) for each user registered in a search apparatus used by a user to search for content. Therefore, even when the footmark is stored in the communication server 101, the user ID may be databased using the user ID registered in the search apparatus used by the user as the identifier.

According to another embodiment of the present invention, the identifier may be information about a user-specific communication connection means or user-specific information transmitted in a wired / wireless communication connection. For example, it may be a serial number registered at the time of launch for each LAN card, which is one of the communication connection means used by the user. Alternatively, the information may be user-specific information transmitted in a TCP / IP environment including an IP (Internet Protocol) address or a MAC address that is provided for wired or wireless communication of the user. In addition, it will be obvious that any information about the communication connection means used by the user or information transmitted to distinguish the user during the wired / wireless communication connection may be used as an identifier for identifying the user.

According to an exemplary embodiment of the present invention, all the footmarks of the user are used as a comparison target with the footmarks of other users regardless of the content to be searched for and search for other users having a relationship with the user in a wide range. However, according to another embodiment of the present invention, a function of determining whether the search unit 104 is a foot mark related to the content when the search unit 104 receives a foot mark for each user from the footmark collection unit 103 as a method for searching more effectively May be included. Since the user may have a preference for a plurality of contents, the foot mark associated with the contents should be used as the basis for determining the similarity when searching for contents. The method for determining a footmark related to the content may include analyzing a website, a product, or a plurality of contents included in the user's footmark, and including a search target content among the website, the product, or the plurality of contents. May be used, for example, a method of extracting information about the content (for example, a data element including the type or content of the content from an XML file) in the code of the website. However, in addition to this, any method of extracting data on a feature of a content from a foot mark may be used.

When the search unit 104 receives a user-specific foot mark related to the content to be searched from the footmark collection unit 103, the search server 104 exchanges the footmark information of another user with the communication server 101 in real time, Compare the footmarks of other users. The footmark is then searched for another user having a similarity exceeding a predetermined value. The predetermined value is determined by the ratio of the total number of footmarks of the user to the footmarks matching with other users, and is used at 60% in the embodiment of the present invention. Accordingly, the user searches for another user who has a foot mark exceeding 60% of the user's total foot marks, and the content corresponding to the other user's foot mark and the content corresponding to the user's foot mark are prioritized. It will be set as the search scope.

According to an embodiment of the present invention, the priority search range of content means that the content corresponding to the footmark of another user and the content corresponding to the footmark of the user are searched first in the content search. If the content corresponding to the footmark of another user and the content corresponding to the footmark of the user do not exist, as described above, the content corresponding to the footmark of another user that does not have a similarity to the footmark of the user. May also be included in the search range. Therefore, first of all, if another user having a similarity of a foot mark exceeding a predetermined value is set as a search range, and if another user having a similarity of a foot mark exceeding a predetermined value is not searched, based on the foot marks of all users. To search for content.

The simulation result for the above-mentioned effect of the content search object is shown in FIG. 4.

Referring to FIG. 4, the first graph 400 represents a probability of visiting a website of a user, and the X-axis lists 10,000 sites, and each site is numbered. The y-axis is the probability of visiting the site. As shown in the first graph 400, a user is showing a probability 404 of performing a search on a limited type of site range. The second graph 401 shows a range of site accesses per actual internet connection, where the X axis represents the number of Internet connections and the Y axis has the same meaning as the X axis of the first graph 400. As shown in the second graph 401, when the user actually accesses the Internet, it can be seen that the visiting site has an error range of up to 300 sites in the range of 9000 sites.

Based on the first graph 400 and the second graph 401, the third graph 402 shows the result of counting the number of visits by the user on the Y axis and the site number on the X axis. The third graph 402 refers to a form in which the first graph 400 is actually measured. On the other hand, the fourth graph 403 shows the range of the website where the user left the foot mark. It can be seen that the footmark of a user does not completely coincide with the first graph 400 and the third graph 402 but is formed within the range of the first graph 400 and the third graph 402. The fifth graph 403a searches for other users having similarities exceeding a predetermined value with the user's foot mark as mentioned above by the search unit 104, and prioritizes contents corresponding to the foot marks of the other users. Shows the result of setting the search range. It is necessary to search all 10000 sites by first setting the content corresponding to the foot mark range 407a including the searched other users, but wider than the user's foot mark range 407 but not all sites. Without this, only a few sites can be searched to provide more efficient and user-friendly content search results.

The search unit 104 may further include a function of providing a search result of the content to the user terminal 100 requesting the content search when another user searches. An example of the content search and result providing function of the search unit 104 mentioned above is shown in FIG. 3. Each foot mark in FIG. 3 is labeled as the same as the content corresponding to the foot mark for convenience.

Referring to FIG. 3, when the user 300 searches 302 for the content A, the user 303 from the communication server 101 that stores the user-specific footmarks collected by the footmark collection unit 103. The foot mark 301 is received. When the search unit 104 receives the foot mark 301 for each user from the foot mark collection unit 103, the search unit 104 communicates with the foot mark 301 of the user 300 through a communication with the communication server 101. For example, it will search for other users who have a Footprint similarity of more than 60%). In FIG. 3, there are three users 300a, 300b, and 300c having a footmark 301 of the user 300 and a footmark exceeding 60%. The search unit 104 then performs the respective footmarks a, b, and c included in the footmark 301 of the user, and the footmarks 301a, 301b, and 301c of the searched other users 300a, 300b, and 300c. Each foot mark (a, b, c, d, e) included in the) is first set as a search range to perform a search.

As shown in FIG. 3, in the embodiment of the present invention, when the search unit 104 displays a search result, the user's footmarks 301a, 301b, and 301c that match the user's footmark 301 are displayed. And calculating a number of other users having a matching foot mark and providing contents corresponding to the footmarks having a high number of users and other users having the matching foot mark as priorities when searching the contents. can do. In FIG. 3, four users include the foot mark a, three users include the foot mark b, two users include the foot mark c, one user include the foot mark d, and the foot mark. There are two users containing e.

When the number of users having the same number of footmarks as footmarks c and e comes out when the priority is provided, the contents corresponding to the footmarks included by the searching user 300 are placed in the priority search 304. In an embodiment of the present invention, the content corresponding to the foot marks d and e which are not included in the foot mark 301 of the user 300 is indicated by the additional search 304. However, the priority search 303 and the additional search 304 may be displayed at once without being distinguished. Thereafter, the search unit 104 provides the search result to the user terminal 100.

In an embodiment of the present disclosure, the search unit 104 may further include a function of determining whether a user's foot mark exists for a search word since there may be content that the user searches for the first time when searching for content. The function may be included together with the function of determining whether the above-mentioned search unit 104 is a foot mark related to the content when the foot mark for each user is received from the foot mark collection unit 103. As a result of the determination, when it is determined that the user's foot mark does not exist for the search word, the search unit 104 may further include a function of directly inputting a temporary foot mark for the search word from the user.

An object of the present invention is to provide a user-friendly content search result using only a search word and a foot mark without causing inconvenience to the user, but if the foot mark does not exist at all, the keyword for the user's desired search word is inevitable for the user. You can also receive a temporary footmark. The temporary footmark may include a method of receiving information related to a search word directly as a keyword, or providing a certain view and allowing a user to select the search word.

The temporary footmark may be recorded in the communication server 101 and used for later retrieval. However, in an embodiment of the present invention, in order to utilize the user's taste change in the user's actual footmark after searching, the search unit 104 stores the footmark input by the user directly in a temporary memory or the like, and then searches. You can delete it when you're done. As mentioned above, since the new footmark can be updated in real time to the communication server 101 after completion of the search, the temporary footmark can be deleted at the same time as the search is completed.

5 is a flowchart illustrating a footmark based content searching method using a footmark based content searching apparatus for each user according to an embodiment of the present invention. In the following description, descriptions that overlap with the description of the foot mark-based content retrieval device for each user will be omitted.

Referring to FIG. 5, first, when a user inputs a search word for content (S500), the searcher 104 receives a user foot mark from the footmark collection unit 103 (S501). To perform. Thereafter, the search unit 104 performs a step S502 of determining whether a foot mark related to the search word exists, and if a foot mark related to the search word does not exist, performs a step of receiving a temporary foot mark (S503). do. Thereafter, based on the user's foot mark or the user's temporary foot mark, searching for another user including a foot mark having a similarity exceeding a predetermined value with a user-specific foot mark and simultaneously receiving the retrieved other user's foot mark S504 and S505 are performed. Thereafter, in operation S506, the footmarks of other users are added to set the search range. After performing the step S507 of setting the sum of the summed users or other users' footmarks as the priority search range of the contents, the search unit 104 prioritizes the contents based on the number of users and other users including the footmarks. In operation S508, a ranking search or a content recommendation list is generated. Finally, in operation S509, the search result or recommendation list may be provided to the user.

According to the foot mark-based content retrieval apparatus for each user according to the above-described embodiment of the present invention, a user may use the website content search, the multimedia content search, and any Internet search that can utilize a search engine including an online shopping mall. By setting the result of summing up the footmarks of other users who share the footmark with the first search range, there is an effect that the user does not provide the search results of the useless content. For example, in an online shopping mall, by setting the search scope to other products of other users who searched for products that matched the products that the user has searched so far, the first user can search for other users who have similar preferences with the users. Since the searched other user's preferred products can be presented to the user as a recommended product, the user can receive the recommended products of other users who purchased the same product as the product they purchased, thereby increasing the reliability of the product recommendation. You can improve and build a user-friendly shopping mall. In addition to the online shopping mall, a similar effect can be obtained when searching for the website or the multimedia content mentioned above, so that the user can be provided with an environment for recommending content recommended by a person who knows it.
