Hereinafter, embodiments will be described in detail with reference to the accompanying drawings.

1 is an operational flowchart illustrating a user behavior based advertisement exposure method according to an exemplary embodiment of the present invention.

Here, the advertisement exposure method according to an exemplary embodiment may be performed by an advertisement exposure module. The ad exposure module may be implemented in various ways, for example, in the form of a script embedded in a web page, or in an application for browsing a web page. Alternatively, the advertisement exposure module may be implemented in the form of an application that is attached to a general web browser in the form of a plug-in or an add-on. Of course, the above-mentioned matters are exemplary, and the embodiment of the advertisement exposure module performing the advertisement exposure method according to the embodiment is not limited by these examples.

Referring to FIG. 1, an advertisement exposure method according to an embodiment includes a step 120 of detecting a keyword corresponding to a web page from a database and a step 130 of exposing an advertisement related to the detected keyword.

At this time, the database may store at least one keyword corresponding to the web page, and at least one keyword stored in the database may be provided in advance based on the actions performed by the existing users connected to the web page.

For this purpose, the advertisement exposure method may further include a step 110 of providing a database based on actions of existing users connected to the web page.

In step 110, the ad exposure module may build a database based on actions performed by existing users who have accessed a particular web page. For example, assume that action A is performed by a user U who has accessed web page P.

In this case, the ad exposure module may determine whether the action A is an action related to the advertisement. If it is determined that the action A is an action related to the advertisement, the advertisement exposure module can extract the keyword K for the advertisement from the action A. The advertisement exposure module may store the keyword K in the database in a form corresponding to the web page P. [

The advertisement exposure module according to another embodiment can construct a database by using a predetermined action related to the advertisement. For example, the ad impression module may determine whether action A performed by user U is a predetermined action related to the ad. If the action A is a predetermined action related to the advertisement, the advertisement exposure module may extract the keyword K from the action A and store the keyword K in the database in a form corresponding to the web page P. [

Furthermore, the advertisement exposure module can accumulate the keywords corresponding to the web page P by treating the actions performed by other users connected to the web page P in the same way.

As will be described in detail below, the ad exposure module may use the database thus formed to determine keywords for an advertisement to be exposed on a web page P. [ Accordingly, the advertisement exposure method according to an exemplary embodiment may provide a technique of performing a target advertisement based on a behavior of a user.

On the other hand, the database can be implemented in various ways. For example, the database may be implemented in the form of a server connected to the advertisement exposure module by wire or wireless. In this case, the advertisement exposure module can communicate with the database via the network. Alternatively, the database may be implemented in a form included in the advertisement exposure module. In this case, the advertisement exposure module can use the database through the database interface. Of course, the foregoing is illustrative only, and embodiments of the database according to one embodiment are not limited by these examples.

In step 120, the ad exposure module may detect a keyword corresponding to a particular web page using a database. For example, the advertisement exposure module can detect a keyword corresponding to a web page from a database in response to a connection to a specific web page by a certain user.

In step 130, the ad exposure module may expose the ad associated with the detected keyword to the user. In this case, the ad exposure module may communicate with the ad server to expose the ad associated with the detected keyword.

More specifically, the advertisement exposure module may transmit a signal for requesting an advertisement to an advertisement server using the detected keyword. The advertisement server may select an advertisement matching the keyword according to a predetermined criterion, and transmit a response signal including the selected advertisement. The advertisement exposure module may expose the advertisement to the user based on the received response signal.

FIG. 2 and FIG. 3 are operation flowcharts illustrating a method of storing a keyword corresponding to a web page in a database according to an exemplary embodiment.

Referring to FIG. 2, an advertisement exposure method according to an exemplary embodiment includes a step 210 of obtaining information related to a connection path to a web page, a step 220 of extracting a search keyword used to access a web page, And storing the retrieved keyword in a database (230).

For example, suppose that the user U accesses the web page P according to the search result on the search web page S. In this case, the advertisement exposure module can acquire the search keyword input by the user U in the search web page S. [

More specifically, the ad exposure module may obtain information relating to the connection path to the web page P in step 210. [ Here, the information related to the connection path to the web page P may be a referrer URL of the web page P.

The ad impression module may extract the search keyword used by the user U to access the web page P from the information associated with the connection path to the web page P in step 220. [

Since the search keyword used to access the web page P is highly related to the web page P, the advertisement exposure module can select the search keyword as a keyword for the advertisement to be exposed in the web page P. The advertisement exposure module may store the search keyword in a database corresponding to the web page P in step 230. [

Although not shown in the drawing, the advertisement exposure module according to another embodiment may preferentially determine whether there is an advertisement matched to the search keyword before storing the search keyword in the database in step 230.

In this case, the advertisement exposure module may communicate with the advertisement server to determine whether there is an advertisement matching the search keyword. The advertisement exposure module may store the search keyword as a keyword corresponding to the web page P in the database according to the determination that there is an advertisement matching the search keyword.

Referring to FIG. 3, an advertisement exposure method according to an embodiment includes extracting (320) an advertisement keyword corresponding to an advertisement selected by a user among advertisements exposed on a web page, and storing the extracted advertisement keyword in a database (Step 330).

For example, suppose that the advertisements C1 and C2 are exposed on the web page P to which the user U is connected. Here, the exposed advertisements C1 and C2 can be determined according to various techniques. For example, the advertisements C1 and C2 may be determined according to a known search advertisement, a context advertisement, and the like. Or the ads C1, C2 may be determined according to the user behavior based advertisement exposure method according to an embodiment.

Here, it is assumed that the user U selects the advertisement C1 among the exposed advertisements C1 and C2.

In step 320, the ad exposure module may extract an ad keyword corresponding to the selected ad C1 in response to the selection of the ad C1.

Since the advertisement keyword corresponding to the selected advertisement C 1 is highly related to the web page P, the advertisement exposure module can select the keyword as a keyword for the advertisement to be exposed in the web page P. The advertisement exposure module may store the corresponding advertisement keyword in the database in a form corresponding to the web page P in step 330. [

The method of exposing an advertisement according to another embodiment may further comprise exposing 310 the ads.

In this case, the advertisement exposure module can perform morphological analysis for the advertisement on the web page P. [ The ad exposure module can use various existing algorithms for morphological analysis. Those skilled in the art will be able to understand these algorithms clearly, so that a more detailed description of morphological analysis is omitted.

The advertisement exposure module can extract the analysis keywords based on the morphological analysis result and expose the advertisement corresponding to the extracted analysis keywords to the user.

4 is a flowchart illustrating an advertisement exposure method when a plurality of keywords corresponding to a web page according to an exemplary embodiment are displayed.

Referring to FIG. 4, when a user accesses a web page in step 410, the advertisement exposure module according to an exemplary embodiment detects a keyword corresponding to the web page from the database in response to the connection in step 420 can do.

At this time, the advertisement exposure module may determine in step 430 whether there are a plurality of keywords detected from the database. If the detected keyword is one, the advertisement exposure module may expose the advertisement using the keyword detected in step 450.

On the other hand, if there are a plurality of detected keywords, the advertisement exposure module may select any one of a plurality of keywords in step 440. At this time, the advertisement exposure module can select any one of a plurality of keywords based on the response rate (for example, click rate) of users who have previously connected to the web page.

For example, when exposing an advertisement corresponding to a specific keyword, the advertisement exposure module updates the number of times the advertisement corresponding to the specific keyword is exposed, and when the advertisement is selected by the user, the number of times the advertisement is selected by the user You can update it. The ad exposure module may store such update information in a database.

Furthermore, the advertisement exposure module can store such information in association with a web page. In other words, the advertisement exposure module can store in the database the number of times the advertisement corresponding to a specific keyword is exposed to a specific web page and the number of times the advertisement is selected by a user in a specific web page.

Referring to FIG. 7A, a database according to an exemplary embodiment may store a keyword in the form of a table 710. For example, row 711 may store a keyword "smartphone case" corresponding to web page P. [ The row 711 may also store information indicating that the click rate of the keyword is 32% in the web page P. [ In addition, the row 712 may store a keyword "Bluetooth earphone" corresponding to the web page P and information indicating that the click rate of the keyword is 5%.

Therefore, the advertisement exposure module can select any one of the plurality of keywords based on the user behavior information provided in advance in the database. According to the above-described example, the advertisement exposure module can select a "smartphone case ", which is a keyword having the highest click rate among the keywords corresponding to the web page P.

The advertisement exposure module according to another embodiment may determine the order in which the plurality of keywords are selected and sequentially expose the advertisements related to the plurality of keywords according to the determined order. Also in this case, the advertisement exposure module can determine the order in which a plurality of keywords are selected based on the response rate (e.g., click rate) of users who have previously connected to the web page. According to the above example, the ad impression module can determine the order in which a keyword with a high click rate (e.g., "smartphone case") is selected earlier than a keyword with a low click rate (e.g., "Bluetooth earpiece & have.

Of course, the above-described table 710 is only an example according to the embodiment, and the form of the table stored in the database is not limited to the above.

5 is an operational flowchart illustrating a user behavior based advertisement exposure method that further uses position information according to an exemplary embodiment.

Referring to FIG. 5, when a user accesses a web page in step 510, the advertisement exposure module according to an exemplary embodiment detects a keyword corresponding to the web page from the database in response to the connection in step 530 can do. In the step 530, the matters described in FIG. 1 through FIG. 4 may be applied as they are, so that a detailed description will be omitted.

The advertisement exposure module may acquire the location information of the user connected to the web page in step 520. [ In this case, the ad impression module may expose the ad associated with both the user's location information and the keyword in step 530. [ For example, the advertisement exposure module can expose advertisements related to both "Gangnam" and "diet" when the acquired location information is "Gangnam" and the detected keyword is "Diet".

Here, the advertisement exposure module can acquire the location information of the user in various ways. For example, the advertisement exposure module can sense a user's location information at a time when a user accesses a web page by using a location sensor such as a GPS (Global Positioning System) sensor.

Alternatively, the advertisement exposure module may detect position information corresponding to a user accessing a web page from a database. In this case, the database may store at least one piece of location information corresponding to the user in advance.

The advertisement exposure module may accumulate at least one location information sensed at a time when the user has accessed the past web page in the database.

Referring to FIG. 7B, a database according to one embodiment may store location information in the form of a table 720. For example, row 721 may store information that a first user has a history of accessing web page P in Gangnam. At this time, the row 721 can count the number of times that the first user accesses the web page P in Gangnam.

The advertisement exposure module may use a unique identifier of the communication device included in the user's mobile communication terminal (e.g., the MAC address of the LAN card) to identify the user.

The advertisement exposure module can estimate the position of the user when a specific user accesses a specific web page by using all the information 731 of the table 720. [

For example, suppose that a first user corresponding to MAC ADDR # 1 accesses web page P. In this case, the ad exposure module may select a row 721 with a higher frequency based on the information stored in the rows 721 and 722. In other words, when the first user accesses the web page P, the advertisement exposure module can determine that the probability of being in "Gangnam" rather than "minutes per minute" is high.

The advertisement exposure module according to another embodiment may estimate the position of a specific user using the partial information 732 of the table 720. [ In other words, the advertisement exposure module can use the location information that is estimated to be frequently located by a specific user regardless of the web page.

For example, assume that a second user corresponding to MAC ADDR # 2 accesses a web page Q. In this case, the advertisement exposure module may consider not only the row 723 and the row 724 corresponding to the web page Q but also the information stored in the row 725 corresponding to the web page R. [ The advertisement exposure module can estimate that the place where the second user is most frequently located at the time of accessing a certain web page is "Busan Haeundae ".

Of course, the above-described table 720 is only an example according to the embodiment, and the form of the table stored in the database is not limited to the above-described matters.

At this time, the advertisement exposure module 610 may further include a location information acquisition unit 613 for acquiring location information of a user accessing a web page. In this case, the advertisement exposure unit 612 may expose the advertisement related to both the location information and the detected keyword.

The advertisement exposure module 610 may include a connection path obtaining unit 614, a search keyword extracting unit 615, an advertisement keyword extracting unit 616, and a storage unit 617 in order to provide the database 620 in advance. .

Here, the connection path obtaining unit 614 obtains information related to the connection path to the web page, and the search keyword extracting unit 615 can extract the search keyword used to access the web page. The advertisement keyword extracting unit 616 can extract an advertisement keyword corresponding to the selected advertisement among the advertisements exposed on the web page. The storage unit 617 may store the extracted search keyword or the advertisement keyword in the database 620.
