Description

How to advertise with keywords {ADVERTISING METHOD USING KEYWORD}

The present invention relates to an advertisement method using a keyword and a computer-readable recording medium recording a program for realizing the method. More particularly, after the keyword information is downloaded to a client, the relevant advertisement is output through the keyword. And a computer readable recording medium having recorded thereon an advertisement method and a program for realizing the method.

In general, a web site adopts a method of delivering information by showing a plurality of pages operated by a web program written in a predetermined program language on a browser program which is a user's client. As these websites become larger and larger than a plurality of simple homepage delivery levels, there is a need to systematically generate, manage, and output a large amount of information.

However, operators operating a portal site according to the prior art simply use a large database to display a search result value corresponding to the search keyword on the user's browser program when the user's search keyword is input. It provides a simple information function that connects a part of the search result value to the searched content when the user selects it.

In particular, while a user reads the searched content, when a user wants to know new additional information on the searched content, encounters an unknown word, or finds text of specific information of interest, a new browser window is opened or is currently being used. The inconvenience of having to repeat the process of checking the search result and linking to the result after inputting the above-described search keyword using the browser screen.

As described above, many portal site information providing systems provide users with only simple information, thus consuming a long search time.

The search service of the portal site according to the prior art to solve this problem, for example, by trying to minimize the user's search time and maximize the convenience by configuring the content predetermined by the user through the service name 'My Yahoo', such as Yahoo! There is a bar.

However, the search results of the 'My Yahoo' are still uncomfortably printed on the web page that the user is uncomfortably reading, and any phrases that are not clearly known are still output. In such a case, the user will also have a difficult time finding, searching, and verifying the information through the aforementioned method or other methods until the desired information is obtained while still searching in the sea of information. In particular, it is very difficult and inconvenient to obtain information in the case of the elderly, who have no experience or knowledge in information retrieval, children, or in an environment where a plurality of search boxes cannot be used together for any reason.

As a prior patent for solving this problem, Korean Patent Publication No. 10-2005-0045650 (published on May 17, 2005, information providing system and method using an info box). The preceding patent is based on the information box processing module, when the user hovers the mouse over a predetermined text or picture that is activated while reading an article such as news, the text of the text, additional information, detailed information, integrated information, shopping information image The present invention relates to an information providing system and method using an info box that can easily identify information such as corporate information, and human life.

The preceding patent includes a specialized DB system that periodically collects data for a specialized DB and collects predetermined contents in a content master DB, and includes an information providing server that combines at least one client terminal with a network (the information providing server is a client). In the information providing method using the info box performed in the web page output from the browser of the terminal (includes an info box processing module for controlling the information box to display the additional information in a separate window based on a predetermined rule), The information box processing module of the information providing server generates an extraction parameter file for each specialized DB in a rule-based manner, and uses the extraction variable file to check final processing contents, load main setting functions, and general functions, and generate information box information. Extracting a keyword by storing the keyword; Recording and storing information box information (the information box information includes at least a search keyword and detailed information) in the content master DB, and the webpage information including the info box information to a client terminal. And transmitting an infobox based on the infobox information to the client terminal.

On the other hand, looking at the other prior art, the website of each newspaper company such as sports shipbuilding uses a method that the advertising window is exposed when the mouse is positioned on the keyword. At this time, the solution used by each newspaper is http://www.keywordlink.co.kr/program/.

In addition, the prior patent and the prior art as described above at least 1 million exposure to receive the advertising information according to the keyword, assuming 4 words per page, if you move the mouse will be connected to the server 1 million x 4 = 4 million times . As a specific example, in the case of using a method of changing a keyword part through a tag in the server as described above, each time a web page is loaded, a client may request a keyword DB server to know about keyword information required for the web page. It is connected (+1 time). Assuming four keywords used as advertisements in the web page content, when the mouse is positioned on the keyword, the client accesses the keyword DB server to find the corresponding information (+4 times). In addition, since the user does not see and end only one page when using the website, the average pageview per capita is assumed to be 90 pages based on the statistics of Ranky.com (see http://news.mk.co.kr/news_forward. php? no = 484812 & year = 2007), if you calculate the minimum of 5 times as 90 pages, you can access 450 times per person. In general, if you have at least 10,000 users for profit, you will have 4,500,000 connections. However, in general, the connection load is the greatest in the Transmission Control Protocol (TCP) communication process.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings, It can be easily carried out. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of an embodiment of a client device and a server system to which the present invention is applied.

As shown in FIG. 1, a system to which the present invention is applied includes a client device 10 and a server system 20, and the client device 10 and the server system 20 are connected to each other through a communication network. And interlocked.

In this case, the client device 10 includes, for example, an installation module 11, a main program module 12, a BHO module 13, a hint module 14, and a hook module 15. Each operation will be described later in detail with reference to FIG. 2.

The server system 20 includes a main server 21, an installation information server 22, a keyword management server 23, a keyword information compression server 24, and a click information management server 25. Each operation thereof will be described later with reference to FIG. 2. Here, each of the servers 21 to 25 may be physically implemented individually, or may be physically implemented in one or both servers.

2 is a flowchart illustrating an advertisement method using keywords according to the present invention.

First, the client device of the user downloads the file of the installation module 11 from the homepage or the library of the distribution company, installs and executes the installation module 11 (201 to 203).

For example, after the user reads the terms on the web page through the client device and agrees to the terms, the user downloads (distributes) the file of the installation module 11 from the distributor's homepage in ActiveX format and receives the installation module ( 11) install and run (201, 203).

As another example, after the user's client device downloads the file of the installation module 11 distributed in the installation form through the library, etc. from the library, the installation module 11 is installed and executed according to the user's agreement (202, 203). ).

Here, the predetermined predetermined area of the installation module 11 includes information of a distribution place (distributor or data room, etc.). This information is like a fingerprint to know how the installation module (installer 11) is distributed.

As the installation module 11 is executed as described above, the installation module 11 transmits installation information such as IP address, MAC address, and distributor information of the client device (user PC) to the installation information server 22 ( 204).

Then, the installation information server 22 stores installation information such as IP address, MAC address, and distributor information received from the installation module 11 in the database DB (205).

When the installation process in the installation module 11 is completed as described above, the main program module 12 is automatically executed (206, 207). The main program module 12 is automatically executed at every boot.

Since the program installation and execution start process 201 to 207 as described above are well known technologies, they will not be described in detail here.

From now on, the main components of the present invention performed in the main program module 12, the BHO (Brower Helper Object) module 13, the hint module 14, and the hook module 15, which are the main components of the present invention. The operation is described as follows. In this case, the main operation according to the present invention includes an operation when the source is a web page and an operation when the application document (Hangul document or Word document, etc.), or may be implemented as one of two operation processes. have.

First, when the main program module 12 executes for the first time or when the mouse is over the keyword, the time from the previous update point (the point at which the keyword information is compressed to be downloaded immediately before) to the keyword over point is a predetermined time (eg : 10 minutes or 30 minutes or 1 hour or 1 day, etc.), access the keyword information compression server 24 and receive "ad text, advertiser, keyword information compressed by the keyword" and decompresses the search. The keyword information is stored in a memory (database) for easy access (208).

Here, the mouse over the keyword means when the mouse is positioned on the keyword.

In addition, the keyword information compression server 24 compresses the advertisement phrase, the advertiser's place, and the keyword according to the keyword information request from the main program module 12, and downloads the keyword information (keyword DB) to the main program module 12. .

At this time, the keyword information compression server 24 compresses the ad text, the advertiser's place, and the entire keyword when the keyword information request is executed at the first execution of the main program module 12, and stores the entire keyword information (keyword DB) in the main program module 12. To download). On the other hand, the keyword information compression server 24, if the mouse over the keyword, if the keyword information request from the main program module 12 as the time from the previous update time to the keyword over time exceeds a predetermined time ad text, advertisers Instead of compressing the entire keyword, only the newly updated advertisement phrase, advertiser, and keyword after the previous update time are compressed to download the updated keyword information to the main program module 12.

Here, keyword information (ad text, advertiser, keyword) is compressed with high compression rate because it is text (character) format information, and the number of keywords is also limited to a limited quantity (e.g. up to 2,000) It provides a small amount of data. That is, according to the results of self-test according to the present invention, the keyword information has a data amount of about 50 KB, which is smaller than the amount of data consumed for outputting a general website. Since the keyword information is not continuously accumulated but is newly updated, the keyword information (keyword DB) stored in the client device is also within about 50 KB.

Here, in general, when the client device and the server communicate with each other, a great load is generated when the client device and the server are connected. In the present invention, when the main program module 12 is first executed (booted) or when the mouse is When the keyword is over, if the time from the previous update time to the keyword over time exceeds a predetermined time, the connection between the client device and the server is made, and thus the number of connections can be greatly reduced compared to the conventional method.

Next, when the source is a web page, look at the main operation according to the present invention.

When the user surfs using the Internet web browser of the client device, the BHO module 13 extracts the source of the web page at the end of loading the web page (209).

The main program module 12 receiving the extracted web page source from the BHO module 13 analyzes the extracted web page source. At this time, the main program module 12 filters the extracted web page source to remove the script, style sheet (css), etc. in order to output pure text. If you use the phrase below, you will get 'hello'.

<script> function a () {result 0; } </ script>
<style> font-size: 9pt </ style>
<a href="xxx"> abc </a> Hello </a>
<script src = "xxx / count.js"></script>

At this time, the keyword information (keyword DB) downloaded and stored is searched with a keyword of "hello", and if the keyword "hello" exists in the keyword information (keyword DB), the keyword "hello" is hyperlinked. If the keyword is changed to a tag having a format, and the keyword 'hello' does not exist in the keyword information (keyword DB), the general character form is maintained as it is (210).

(E.g. Hello-> <a href="xxx"> hello </a>)

In this case, the reason for changing the keyword 'hello' into a tag format is to change the keyword in general characters into a keyword in which the hyperlink is processed.

Thereafter, the BHO module 13 that receives the changed webpage source (tag source tagged with keywords) from the main program module 12 corresponds to the modified webpage source (tag source tagged with keywords). The web page is updated (overwritten) and output (211). Accordingly, the keyword is changed to a form in which the hyperlink is processed and output.

When the mouse is positioned on the tag of the keyword portion updated and output as described above or when a click occurs, the BHO module 13 transmits corresponding keyword information to the hint module 14 (212).

Here, in a preferred embodiment of the present invention, the BHO module 13 is a hint module for keyword information (advertisement phrases, advertisers, keywords) immediately corresponding to a mouse positioned on a tag of the keyword portion updated and output as described above. (14), or in another embodiment, when the user intentionally clicks a tag of the keyword portion in order to obtain information on the keyword, the corresponding keyword information is transmitted to the hint module 14.

Thereafter, the hint module 14 receiving the keyword information from the BHO module 13 outputs a box including keyword information (ad text, advertiser, keyword) near the coordinate where the mouse is located (213).

At this time, the box outputs the advertisement, and when the user clicks on the box or the advertisement, it moves to the corresponding advertiser.

As such, when the click on the box or the advertisement text occurs in the hint module 14, the click information such as keyword information, IP address, MAC address, and distributor code is encrypted and clicked through a new window including the corresponding encryption value. Move to management server 25 (214). Since the subsequent operation is similar to the known technology, the detailed description will not be given herein.

Next, when the source is an application document (Hangul document or Word document, etc.), the main operations according to the present invention will be described as follows.

After the keyword information download process 208 is performed in the main program module 12, when the user executes an application document (such as a Korean document or a word document) on the client device, the hook module 15 selects a mouse position. Acquire and extract the text of the location. At this time, since the extracted text is one word, the surrounding text is searched. For example, if you have the following document, if the mouse is located at 'e', the text '... Hello world' is searched, and the mouse position in the text is calculated as the sixth.

Good morning ... Hello world.!

At this time, while checking words to the left and right centered on the searched string and the mouse position as described above, it is shortened to a range until a special character and a space appear. Accordingly, the keyword 'Hello' may be extracted since both sides of the 'Hello' are blank (215).

The main program module 12 that receives the extracted keyword Hello from the hook module 15 searches for the downloaded keyword information (keyword DB) with the extracted keyword Hello. In step 216, if the extracted keyword does not exist in keyword information (keyword DB), the process proceeds to step 215. If the extracted keyword exists in keyword information (keyword DB), corresponding keyword information (ad text, Advertiser, keyword) is transmitted to the hint module 14 (217).

Accordingly, the hint module 14 which receives the keyword information from the main program module 12, when the mouse is positioned or clicked on the matching keyword as described above, the keyword information (ad text, After the process of outputting a box including an advertiser's address, a keyword), the process is performed.

Next, the operation process of the server system side is as follows. At this time, since most of the server-side operation process is known technology, the process will be briefly described.

The main server 21 performs functions such as advertiser login / logout / subscription as in the known technology (218).

In addition, the main server 21 performs the deposit / withdrawal management function for the deposit to facilitate the payment for the advertisement, as in the conventional air technology (219).

In addition, the keyword management server 23 supports an advertiser to search for a required keyword and set an advertisement phrase, an advertiser place (for example, an advertisement URL) to the keyword, and then use it after payment through a deposit.

The keyword information compression server 24 compresses the keyword information (keyword, advertisement phrase, advertiser place) processed by the keyword management server 23 and stores them in a file form, and informs the time when the keyword information is updated. When the entire download request or the update request is received from the program module 12, the newly updated keyword information after the entire keyword information file or the previous update time is compressed and transmitted (221).

As described above, the click information management server 25 blocks fraudulent clicks by using the MAC address and the IP address that are transferred when the keyword is exposed through the hint module 14, and deducts and distributes the amount of the keyword of the advertiser. After reflecting the performance per click of the operator, the mobile station moves to the advertisement URL (222).

And the main server 21, such as the known technology, such as distribution provider login / logout / membership, such as the function to output statistics and revenue per click performance, the function to output statistics and revenue per distribution In addition, it performs a function of calculating the revenue according to the performance of the distribution provider (223 to 226).

On the other hand, the method of the present invention as described above can be written in a computer program. And the code and code segments constituting the program can be easily inferred by a computer programmer in the art. In addition, the written program is stored in a computer-readable recording medium (information storage medium), and read and executed by a computer to implement the method of the present invention. The recording medium may include any type of computer readable recording medium.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

The present invention can be used for an information providing system or the like.
