The present invention relates to a keyword-related advertisement system and method, and more particularly, to an advertisement system and method for providing advertisement content suitable for a user based on various keywords input by a user on a terminal.

In general, in the case of keyword advertising through a search site, when a user accesses a site providing a search service and enters a search word in a search box or enters a search word through a search box of a separate application provided by the search site, the search word Ads with keywords corresponding to the above are provided. In this case, an advertisement is placed at the top of the searched site in the form of a banner or a text link to induce a user to click on the advertisement. These keyword advertisements are rapidly growing because they have a large advertising effect in that relevant advertisements are immediately exposed to users interested in a product or service corresponding to a keyword.

However, in general, since the user can use the search service without logging in, detailed information related to the user cannot be known at the time of keyword advertisement. Therefore, the optimal target advertisement for the user cannot be made, and only the keyword advertisement corresponding to the search word is exposed.

Even if a user is logged in to a search site, the targeted advertisement executed after grasping the user's information may delay the loading time of the search page, which may make the user feel uncomfortable. Such personalized keyword advertising is not executed.

In addition, the existing keyword ads are displayed on the search results page that is exposed after the user enters a search box into the search box, so the user can analyze the various search behaviors that the user enters to obtain specific information. Execution is impossible. In other words, the user may obtain the desired information with only one search, but sometimes the user may search several times on one site or repeatedly. Existing search advertisements simply provide advertisements related to search terms entered by the current user, and thus, it is impossible to provide comprehensive advertisements for all search activities performed within a specific time range.

In addition, in the past, advertisers have to apply for ads on each search site individually in order to advertise keywords. Therefore, it is true that advertisers are burdened with advertising costs. You will hear this. In addition, such keyword ads are actually made only in large search sites, and the advertising cost of keyword ads is set high because only a few sites can execute keyword ads. In particular, since the advertisement cost calculation based on the click of the advertisement is mainly based on the IP address of the user terminal, there are frequent cases of deliberately clicking the same advertisement for the purpose of exhausting the advertisement cost of competitors. This side effect occurs because the criterion for determining the validity of the advertisement click is not based on user information such as an ID for identifying an individual but based on an IP address.

In addition, the existing keyword advertising has a limitation that it is provided only on the search results page provided by the search site.

In addition, the existing keyword advertising has a disadvantage that the user's search behavior can be identified only when the user accesses a search site providing a search service.

As a related art keyword advertising technology, there is a "content keyword advertising system" described in Korean Patent Application, Application No. 10-2003-0070442. This conventional technology is to extract the search word and provide a corresponding advertisement when the search word input by the user in a predetermined website is transmitted to the search server. However, in this prior art, an advertisement is provided when a search term is included when a URL is sent from a corresponding website, and whether or not the service is determined by a search site that receives the URL and performs a search does not facilitate the advertisement. .

In addition, since the module for extracting a search word only stores the URL address of the advertiser and provides the search word only by a link method to the advertiser homepage based on the stored URL address, various forms based on user information are provided. Advertising (eg, mobile advertising, flash advertising, etc.) is not easily made.

In addition, since the most frequent keyword words are extracted from the web document of the web site for advertisement, it takes up a lot of memory because the data of the web document must be retrieved when the keyword is extracted. This causes a burden on the user's use of the terminal, and makes the user feel rejected to use the program, thereby preventing efficient advertisement.

Therefore, the technical problem to be achieved by the present invention is to solve the conventional problems, a system that can provide an optimal advertisement based on the keyword generated by all the search behavior on the user's terminal, and the user related information; To provide a way.

Another object of the present invention is to provide a system and method for allowing a keyword advertisement based on user related information without a user logging in to a predetermined system.

The advertisement system according to the characteristics of the present invention for achieving the above technical problem is a keyword-related advertising system that is connected through a network with the user terminal, the advertising content, the user consists of the search information according to the past search behavior A database server that stores a plurality of pieces of information including search history information for each user; A processing server for generating a keyword corresponding to the advertisement content to be provided to the user based on the search information and the search history information provided from the terminal; And an advertisement transmission server configured to transmit advertisement contents related to the keyword to a user terminal. Here, the user terminal includes a keyword extraction module for extracting a search word input according to a user's search action on the terminal, generating search information including the search word, and providing the search information to the processing server.

In addition, the advertising method according to another aspect of the present invention, in the advertising method for providing a keyword-related advertising to the user terminal in a system connected to the user terminal and the network, the user terminal is input according to the user's search behavior on the terminal A keyword extraction module is provided for extracting a search term and generating search information including a search term and providing the search term to the system. The advertisement method includes: receiving search information provided from the keyword extraction module; Generating search history information consisting of search information according to a search action performed by the user in the past, and a keyword corresponding to advertisement content for providing the received search information to a user; And transmitting the advertisement content related to the keyword to the user terminal.

Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present disclosure. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

In addition, when a part is said to "include" a certain component, this means that it may further include other components, except to exclude other components unless otherwise stated.

Keyword-related advertising system according to an embodiment of the present invention (hereinafter, referred to as an advertisement system for convenience of explanation) 100, as shown in the accompanying Figure 1, the network (Internet, wireless communication network, future network, etc., all wired and wireless networks It is connected to a plurality of user terminal 300 through the (200). In addition, it may be connected to the affiliate site server 400 that provides a predetermined service, such as providing a search service through a network.

The user terminal 300 is a communication device that can transmit and receive data by accessing the purchaser payment system 100 through the network 200, and specifically, a computer that can be connected to the network 200 by wire, a TV that can access the Internet, and the like. It may be a wired terminal including, or a wireless terminal including a mobile phone, PDA, etc. that can be connected to the network 200 by wireless. For convenience of description, the terminal 300 is divided into a user terminal 310 and a wireless terminal 320. The user terminal described below is referred to collectively as a number "300" and a number, and "320" is given to a wireless terminal provided with the advertising content. However, the present invention is not limited thereto.

The user terminal 300 is provided with a keyword extraction module 500 for extracting a search word input in accordance with all search actions performed on the terminal. The keyword extraction module 500 may be downloaded and installed from the advertisement system 100 to the user terminal 300 through various paths. In addition to the advertisement system 100 according to an embodiment of the present invention, the keyword extraction module 500 may be connected to the advertisement system 100. It may be provided to the user terminal 300 from the server of the other site, that is, affiliated site server 400.

The affiliate site server 400 is a server of sites that provide various services on a network in cooperation with the advertisement system 100 according to an exemplary embodiment of the present invention. For example, it may be a site operated by an advertising agency that executes a push advertisement to the user on the premise of a predetermined reward for receiving the advertisement from the user, or may be a site affiliated with the advertising agency. Or it may be a site that provides an online service through a messenger service or a multimedia player to the user. A site providing an affiliate online service may apply a keyword advertisement according to an embodiment of the present invention to a pop-up advertisement, a pop-under advertisement, a banner advertisement or a video advertisement through a messenger or a multimedia player.

Meanwhile, the keyword extraction module 500 may also be referred to as a client program, and extracts a search word input according to all search actions performed on the terminal. In particular, the extracted search terms are stored and managed along with the search time information. 2 illustrates a structure of the keyword extraction module 500 for implementing such a function.

As shown in FIG. 2, the keyword extraction module 500 includes a search term code extractor 510, a search term code restorer 520, an interface unit 530, and a storage unit 540.

The search term code extractor 510 extracts a search term input according to a search action performed on the user terminal. In particular, if a search word input according to various search actions is converted into a search word code according to a predetermined rule, such search word code is extracted.

The search word code recovery unit 520 restores the search word code extracted by the search word code extractor to the original character form (for example, Korean or English).

The storage unit 540 stores predetermined information or user terminal related information provided to the keyword extraction module. For example, when the keyword extraction module is downloaded from a predetermined affiliate site server or a system according to an embodiment of the present invention, a predetermined identification code is assigned to the keyword extraction module, and the identification code is stored in the storage unit 540. Stored and managed. The identification code may be referred to as a so-called "module identification code", which may be used as an identification code for a user performing a certain search action. Therefore, the user can be identified based on the module identification code even if the user does not go through an authentication process such as logging in to a predetermined affiliated site or the system of the present invention.

In addition to the module identification code, an IP address assigned when the user terminal accesses a predetermined site server or system, a MAC address uniquely assigned to the terminal, and the like may be stored.

The interface unit 530 includes a search word provided from the search word code recovery unit 520, and further includes search information including search location information, information on a place where the search word input is made, search time in which the search word is input, and the like. Send to the advertising system 100. The search location information may be, for example, information (URL address, etc.) of the search site when the user accesses a predetermined search site and inputs a search word.

Meanwhile, the search information generated by the interface unit 530 may be transmitted to the advertisement system 100 in real time. In addition, the search information generated by the interface unit 530 may be temporarily stored in the storage unit 540 and then set at a time or a request for information transmission from the advertisement system. If a predetermined condition of is satisfied, it may be transmitted to the advertising system 100. For example, only search information extracted during a predetermined range of time may be transmitted. In this case, advertisement marketing may be developed targeting only keywords searched within the range.

In addition, if the user is directly or connected to the advertising system 100 according to an embodiment of the present invention through the affiliate site server 400, the interface unit 530 directly transmits the search information to the system 100 in real time, If the system is not connected to the system, the search information may be stored in the storage unit 540, and the stored search information may be transmitted to the system 100 when the system is connected to the system. Meanwhile, the search information stored in the storage unit 540 may be deleted as soon as it is transmitted to the system 100.

The keyword extraction module 500 having such a structure may be automatically executed at the same time as the OS of the user terminal 300 is driven, and is mounted on a messenger, a music player, a multimedia player, a P2P program, a mini homepage, a web browser, a toolbar, and the like. It can also be run automatically when you log in.

If it is implemented to be automatically executed when the OS or web browser of the user terminal is driven, the search word according to the user's search behavior may be extracted and provided to the system 100 without the user directly driving the keyword extraction module 500. .

Meanwhile, when the search term code extracting unit 510 and the search term code restoring unit 520 are referred to as a "search information management unit" and the interface unit 530 and the storage unit 540 as "information processing unit", the search information. The management unit and the information processing unit may be implemented in a form separated from each other. For example, the retrieval information management unit is pre-built in the terminal itself to be automatically executed at the same time as the OS operation of the terminal, or embedded in the web browser and implemented at the same time as the driving of the web browser. A music player, a multimedia player, a mini homepage, or the like, may be implemented in a form that is mounted in a separate program that can perform a connection function (or login function) with the advertisement system 100.

Next, a structure of an advertisement system that provides an advertisement based on a search word extracted according to a user's search behavior in connection with the keyword extraction module 500 having such a structure will be described.

3 is a structural diagram of an advertisement system according to an embodiment of the present invention.

The advertisement system 100 according to the embodiment of the present invention includes a processing server 10 for processing search information and user related information, an advertisement transmission server 20 for transmitting related advertisements to a predetermined terminal according to a processing result of the processing server, And a database unit 30 in which related information is stored.

The database server 30 stores various kinds of information, and specifically, the member information database 31, the search history information database 32, the keyword advertisement list database 33, and the advertisement database 34 storing advertisement contents. It includes.

The member information database 31 includes user identification information (for example, a password, a name, a social security number, a wireless terminal telephone number, an e-mail address, etc. for logging in to correspond to a user ID), and a reward provided upon receipt of an advertisement for each user. Related information (for example, reward points given in correspondence with a user ID, an offer date, cumulative points, etc.), and information on a user's field of interest are stored. Such user profile information and user's field of interest information may be collectively referred to as "user related information".

The search history information database 32 stores the search information provided from the keyword extraction module 500, and in particular, the search information is stored in response to a user ID or / and a module identification code assigned to the keyword extraction module 500. It is. In this way, the information consisting of the search information according to the user's past search behavior is called the search history information.

The advertisement list database 33 stores lists of advertisement contents corresponding to each keyword, and the list includes an advertisement identification code assigned to the advertisement contents. The advertisement database 34 stores advertisements corresponding to advertisement identification codes, that is, advertisement contents.

On the other hand, the processing server 10 is a module interface unit 11 for transmitting and receiving information with the keyword extraction module 500, a member information processing unit 12 for performing user authentication and compensation processing according to the user's advertisement received, keyword extraction A search information processor 13 which processes the search information provided from the module to generate related keywords, and an advertisement information processor 14 which finds relevant advertisement content based on the keyword provided by the search information processor and provides the related advertisement content to the advertisement transmission server 20. ).

In particular, the search information processing unit 13 extracts a keyword corresponding to a search word from the search information provided from the keyword extraction module 500, and also searches the search history information database 32 to provide a module identification code or the code assigned to the keyword processing module. The search information corresponding to the identification code of the authenticated user is analyzed. The advertisement information processor 14 finds relevant advertisement contents from the advertisement list database 33 and / or the advertisement database 34 based on the extracted keywords and / or analysis results and provides them to the advertisement transmission server 20.

On the other hand, the search information processing unit 13 analyzes the search history, that is, information searched by the user within the set period, to analyze what kind of search terms the user mainly used, or the user personally interested in the member information database 31. It analyzes the information on the field or the user's personal information, etc., and extracts a keyword (first keyword) based on the analysis result and provides it to the advertisement information processing unit 14. In addition, a keyword (second keyword) related to a search word is extracted from the search information provided from the keyword extraction module 500 and provided to the advertisement information processor 14. Accordingly, the advertisement information processing unit 14 searches the advertisement list database 33 based on the first and / or second keywords to find the identification codes of the related advertisement contents, and from the advertisement database 34 based on the found advertisement identification codes. The relevant advertisement content is read and provided to the advertisement transmission server 20.

On the other hand, if the first and second keywords provided from the search information processing unit 13 are not included in the advertisement list, the search information provided from the keyword extraction module is stored in the search history information database 32 to request a new advertiser in the future. In some cases, it may be used for keyword advertising.

Meanwhile, when the advertisement information processing unit 14 extracts relevant advertisement contents based on the extracted first and second keywords and provides them to the advertisement transmission server 20, the wireless terminal assigned to the user from the member information database 31 is provided. Find a wireless telephone number or an e-mail address, and transmit the advertisement content to a corresponding wireless telephone number or e-mail address.

The advertisement transmission server 20 transmits the advertisement content provided from the processing server 10 to the keyword extraction module 500 or the corresponding user terminal. In addition, the advertisement content is also transmitted to a wireless terminal having the wireless telephone number.

Meanwhile, the advertisement content provided from the advertisement transmission server may be processed by the keyword extraction module 500 of the terminal and displayed on the terminal. In this case, the keyword extraction module 500 may be mounted in a separate program such as a messenger to express an advertisement transmitted from the advertisement system 100 as a banner advertisement or a video advertisement. Or it may be processed and displayed by a separate program on the terminal. The advertisement processed as described above may be expressed in the manner of a pop-up window and a pop-under window.

The structure of a system according to an embodiment of the present invention is classified according to its processing function and is not limited to the above-described one. For example, when a keyword advertisement according to an embodiment of the present invention is to be deployed on a predetermined affiliated site where a banner advertisement or a video advertisement is deployed through a messenger, a music player, a multimedia player, or a P2P program, the advertisement transmission is performed. The server 20 may be implemented by being included in a server operated at an affiliate site. In addition, the advertisement transmission server 20 may be implemented in a form included in the processing server 10.

Next, a keyword-related advertisement method according to an embodiment of the present invention will be described based on this structure.

According to an exemplary embodiment of the present invention, a user's search behavior includes inputting a search word in an input window by accessing a predetermined site, inputting a predetermined address in an address bar on a web browser, and accessing a predetermined website. This includes all actions of performing a search word input using a predetermined program on a user terminal, such as inputting a search word using a search application such as a search toolbar.

When the user inputs a predetermined search word, the user inputs a predetermined search word, and displays similar search words that partially match the search word input among the stored search words, so that the user can search the search word only by selecting action such as a click action. Even without inputting all of them, a predetermined search word may be automatically displayed in a complete form and thus a function of inputting may be provided. Such a function may be referred to as an "autocomplete function", which may be provided in a web browser mounted on a terminal, or may be provided in a search site accessed by a user.

Most users now use a web browser to access the Internet. Although there are differences among web browsers, certain web browsers (such as Microsoft's Internet Explorer) provide "autocomplete." 4 is an exemplary screen illustrating a process of selecting an autocomplete function on a web browser. After the auto complete function is set, if a word is entered in the input window of the web browser, similar words previously entered are listed in a small window, and the user clicks the word. The word is selected.

In order to set the auto-complete function, when the user sets the 'form' in the 'auto completion target' on the auto-complete setting screen as shown in FIG. 4 displayed on the terminal 300, the word entered as above is automatically entered. The completed function will be performed. If the user sets the 'web address' as the target of auto-completion, the web address entered by the user is saved.If the user name and password used for the 'form' is set, the user's ID and password are saved. When entering a web address or username and password, the corresponding word entered previously is automatically displayed for the user to select. In this case, the object stored according to the auto-completion function may be designed to extract only a simple search word necessary for keyword advertising except for an ID and a password.

The stored information is also called "Protected Store Key" in terminology, and this protected memory key is converted into a separate code and stored in a location that is not searched by a normal searcher for security reasons. In other words, the search word input according to the auto-completion function is encoded and stored in a predetermined code. Accordingly, the keyword extraction module 500 extracts the search word code stored as described above and decodes it.

5 is an exemplary diagram for an autocomplete function. When the autocomplete function is set, when the user enters a search word as shown in FIG. List and include search terms. Therefore, the user can enter a complete word in the input box by simply selecting the mobile phone from the search terms listed without having to enter the mobile phone.

The automatic completion function may be equally applied to a case where a website address to be accessed is input in the address box as shown in FIG. 5 (b). FIG. 5 (b) is an exemplary diagram illustrating an automatic completion function when a domain name is input in a native language (eg, Korean).

When a search word is input according to an autocomplete function provided by a web browser of the user terminal, the search terms to be input are stored in a file at a specific location of the terminal. Therefore, the keyword extraction module 500 according to an embodiment of the present invention extracts a search word stored from the file. In addition, when a search word is input according to an auto-completion function provided at a predetermined site, as shown in (c) of FIG. 5, the input search word is converted into a predetermined code and then a URL address for moving to a search result page. It is included in the provided to the server of the site, at this time the keyword extraction module 500 extracts a search word from the URL address. In addition, various search methods may extract search words input according to a user's search behavior on the terminal.

Therefore, users according to an embodiment of the present invention should be provided on the terminal 300 by receiving the keyword extraction module 500 that performs the above functions from the advertisement system 100 or the predetermined affiliate site server 400. In addition, the user agrees to be provided with a keyword-related advertisement in advance through the advertisement system 100, and is registered in the member information database 31 of the advertisement system 100. This consent process may be performed through the system 100 or through an affiliate site server 400. In the case of the affiliate site server 400, the server 400 provides the system 100 with information about users who have agreed to receive an advertisement, and the system 100 registers the information in the member information database 31. Manage it.

6 is a flowchart illustrating a keyword-related advertisement method according to a first embodiment of the present invention, and FIG. 7 is an exemplary view illustrating a process of performing the method.

When a user inputs a predetermined search word on the terminal 300 on which the keyword extraction module 500 is installed (S100 to S110), the keyword extraction module 500 extracts the input search word as described above (S120).

Next, the keyword extraction module 500 transmits the search information including the extracted search word, the search time in which the search word is input, and the search site address to the advertisement system 100 when the search is performed at a predetermined site. The module identification code assigned to is included in the search information and transmitted to the advertisement system 100 (S130). Therefore, even if the user is not logged in to the system 100, analysis of the user's search history information can be performed based on the module identification code.

The advertisement system 100 analyzes at least one of the user's search history information, the user interest field information, and the user's personal information, generates a first keyword related thereto, and extracts a second keyword corresponding to the search word from the search information. . In operation S140 to S170, a predetermined advertisement is provided to the user based on the first and second keywords.

For example, the search information processing unit 13 of the processing server 10 analyzes the search history, that is, the information searched by the user within the set period, to analyze what kind of search terms the user mainly used, or the member information database 31. ) Extracts a keyword (first keyword) related thereto by analyzing information about a field of interest of the user or user's personal information. The keyword (second keyword) is extracted from the search information provided from the keyword extraction module 500.

The extracted first and second keywords are transferred to the advertisement information processor 14, and the advertisement information processor 14 determines whether there are advertisement lists corresponding to the first and second keywords from the advertisement list database 33. Check it. When there are advertisements with related keywords in the advertisement list, corresponding advertisement contents are retrieved from the advertisement database 34 based on the corresponding advertisement identification code and provided to the terminal 300 of the user (S180).

Accordingly, in response to the user simply inputting a search word, an optimal target advertisement is achieved based on the analysis of not only the input search word but also the user's search history information and the user's field of interest and personal information.

Subsequently, when the user who receives the advertisement wants to receive a predetermined reward according to the confirmation of the advertisement, the processing server 10 of the system 100 performs a login process in a state in which the user is not logged in, and then provides the user with a predetermined reward point. Provide (S190 ~ S220), and provides a reward point immediately in the logged-in state (S230).

According to this embodiment, it is possible to maximize the effect of the push advertisement by minimizing the rejection that the user receives due to the indiscriminate push of the advertisement and by sending an advertisement in a field of interest to the user.

In addition, the keyword extraction module according to an embodiment of the present invention is installed in the user terminal and automatically executed with the operation of the OS, so that the search terms of all users independently input on the web browser even when the user is not connected to the advertisement system. Can be extracted and stored with the time information. Therefore, after the user is connected to the advertising system, keyword advertising is performed based on search terms in consideration of time information. As a result, the advertiser can grasp the current and past search behavior of the user, and can optimize the advertisement based on this.

Next, a keyword related advertisement method according to a second embodiment of the present invention will be described. The second embodiment is a case in which an advertisement is provided to a predetermined wireless terminal of a user, and particularly, a process of providing an advertisement while the user is logged in to the advertisement system.

8 is a flowchart illustrating a keyword-related advertisement method according to a second embodiment of the present invention, and FIG. 9 is an exemplary view illustrating a process of performing the method.

In the state where the keyword extraction module 500 is installed in the terminal 300 as described above, the user may log in to the system 100 (S300 to S310). In this case, the keyword extraction module 500 transmits the search information including the search word, the search time, and the search site address inputted according to the user's search behavior to the advertisement system 100 (S320 to S340). At this time, the search information may not transmit the module identification code because the user is logged in to the system.

After that, the advertisement system 100 analyzes the search history information (the search history information is analyzed based on the ID code of the logged-in user in the second embodiment), the user interest field information, and the user's image as in the first embodiment. Analyze at least one of the information and generate a first keyword related thereto, extract a second keyword corresponding to the search word from the search information, and provide a predetermined advertisement to the user based on the first and second keywords ( S350 to S380).

In particular, in the second embodiment of the present invention, in order to provide an advertisement to the user's wireless terminal, the wireless telephone number of the wireless terminal corresponding to the user's identification code is extracted from the member information database 31, and the extracted wireless telephone number is extracted. Sending a callback message informing the transmission of the advertisement to the terminal 320 having (S390 ~ S400).

When the user receiving the callback message transmitted as described above accesses the message based on the message in order to receive the advertisement, the advertisement system 100 transmits the advertisement content corresponding to the callback message to the user's wireless terminal 320 (S410 to S). S440). In this case, the advertisement content may be transmitted to the wireless terminal after predetermined processing (compression, etc.) according to the specification of the user's wireless terminal. When the user confirms such advertisement contents, the advertisement system 100 provides a predetermined reward point to the user (S450 to S460).

According to this embodiment, the effect of the push advertisement can be maximized by sending an advertisement of a field of interest to the user through the wireless terminal.

Meanwhile, in the above-described embodiment, the keyword extraction module 500 installed in the user terminal restores a search word code generated according to a user's search behavior into a search word in an original text form, and then processes the search word code as search information as described above. In contrast to this, although transmitted to the system 100, the search word code itself, which has not been restored, may be treated as search information and transmitted to the system 100. That is, when the keyword extraction module 500 includes the search word code generated according to the search behavior and includes the search information without the restoration process in the search information and transmits the search information to the system 100, the system 100 includes the search information. The search word code may be restored to a search word in an original character form, and processed according to the above-described process based on the restored search word to provide an advertisement to the user. In this case, the search word code reconstruction unit 520 of the keyword extraction module 500 is implemented in the form of being included in the system 100.

As a person skilled in the art can implement the process of providing the corresponding advertisement while the system 100 performs the search word code restoration as described above, a detailed description thereof will be omitted.

Meanwhile, the above-described method or keyword extraction module may be implemented in the form of a program stored in a computer-readable recording medium.
