The search information providing system 10, the user terminal 20, the search site server 30 and the Web server 40 are connected via the Internet network N. The user terminal 20 is a communicable terminal device used by a user. The search site server 30 is a server device that provides a search service using a search engine to the user terminal 20. The web server 40 is a server device that provides various contents to the user terminal 20. The search information providing system 10 is a system that provides highly useful search information to the user terminal 20 that accesses the search site server 30 and uses a search service.

  The functional configuration of the search information providing system 10 will be described with reference to FIG. FIG. 2 is a block diagram showing a functional configuration of the search information providing system 10. As shown in the figure, the search information providing system 10 stores a control unit 11 that controls the search information providing system 10 as a whole, and an update database 120 and a keyword information database 121 that are used for processing in the control unit 11. Part 12.

  The search information providing system 10 may be configured with one server device or a plurality of server devices. When configured by a plurality of server devices, for example, it may be configured by a server device that implements the control unit 11 and a server device that implements the storage unit 12. Furthermore, various functions included in the control unit 11 and each database stored in the storage unit 12 may be configured to be distributed among a plurality of server devices.

  The data structure of the keyword information database 121 will be described with reference to FIG. FIG. 3 is a diagram illustrating a data configuration of the keyword information database 121. The keyword information database 121 is a database for managing keyword information, and includes, for example, a URL (Uniform Resource Locator), a search keyword, importance, and average browsing time as data items. The URL stores storage location information for uniquely specifying the storage location of the Web page. The search keyword stores the search keyword used to access the Web page corresponding to the URL. The importance level stores a value indicating how important the search keyword is with respect to the contents of the Web page corresponding to the URL. In the average browsing time, an average value of the time that Web pages corresponding to the same URL and search keyword were browsed at the time of one access is stored.

  The control unit 11 illustrated in FIG. 2 includes an information reception unit 111, a keyword acquisition unit 112, a search information providing unit 113, and a DB update unit 114.

  The information receiving unit 111 receives various types of information transmitted from the Web server 40 accessed by the user terminal 20. Examples of the various types of information include access start information, access end information, and mouse position information, which will be described later. The access start information, access end information, and mouse position information received by the information receiving unit 111 are stored in the update database 120 as DB update data for updating the keyword information database 121.

  The access start information is obtained by the Web server 40 when the user terminal 20 that has acquired the search result from the search site server 30 starts access to the Web page of the Web server 40 corresponding to one URL included in the search result. Information to be issued.

  As shown in FIG. 4, the access start information includes, for example, a user ID, URL, keyword, and access start time. Identification information for uniquely identifying the user terminal 20 is stored in the user ID, and the URL of the Web page of the Web server 40 accessed by the user terminal 20 is stored in the URL. The keyword stores the keyword input on the Web page of the search site server 30 that the user terminal 20 was accessing immediately before the Web server 40. This keyword can be acquired from referrer information, for example. In the access start time, time information when the user terminal 20 starts access to the Web server 40 is stored.

  The access start information only needs to include at least the URL of the Web page of the Web server 40 accessed by the user terminal 20 and the keyword input on the Web page of the search site server 30. In addition to the data items described above, the URL of the Web page of the search site server 30, the domain information of the Web server 40, a part of the Web page information of the Web server 40 (for example, a title), etc. are included in the access start information. It is good as well.

  The access end information is information issued by the Web server 40 when the user terminal 20 moves from the Web page of the Web server 40 to another Web page. Examples of other web pages include the web page of the search site server 30 that the user terminal 20 has accessed immediately before the web server 40, another web page of the web server 40, and the like.

  As shown in FIG. 5, the access end information includes, for example, a user ID, URL, keyword, and access end time. The user ID, URL, and keyword are the same as the user ID, URL, and keyword of the access start information. In the access end time, time information when the user terminal 20 ends access to the Web server 40 is stored.

  The mouse position information is information indicating the position of the mouse pointer of the user terminal 20 that is accessing the Web page of the Web server 40. The mouse position information is acquired from the user terminal 20 at any time by the Web server 40 while the user terminal 20 is accessing the Web server 40, and is transmitted to the search information providing system 10. The interval for acquiring the mouse position information can be arbitrarily set as long as it can be determined whether or not the mouse is operated.

  The mouse position information includes, for example, a user ID, time, and coordinates. The user ID is the same as the user ID of the access start information. In the time, time information when the position of the mouse pointer is acquired is stored. In the coordinates, coordinate information indicating the current position of the mouse pointer displayed on the display screen of the user terminal 20 is stored.

  The keyword acquisition unit 112 illustrated in FIG. 2 acquires another keyword different from the keyword included in the access start information from the keyword information database 121 using the keyword included in the access start information received by the information reception unit 111. To do. The keyword acquisition unit 112 acquires other keywords as follows, for example.

  First, the keyword acquisition unit 112 extracts keyword information having a search keyword that matches the keyword from the keyword information database 121 using the keyword included in the access start information as a key.

  This will be specifically described with reference to FIGS. 3 and 4. As shown in FIG. 4, when the keyword included in the access start information is “Ginza lunch”, as keyword information having a search keyword matching “Ginza lunch”, the keyword information k1, k2, k5 is extracted. In addition, before extracting keyword information, it is good also as normalizing the keyword of access start information using a well-known morphological analysis method, a syntax analysis method, etc. FIG.

  Subsequently, the keyword acquisition unit 112 selects a URL different from the URL included in the access start information from the extracted keyword information, and extracts keyword information having a URL that matches the selected URL from the keyword information database 121.

  This will be specifically described with reference to FIGS. 3 and 4. As shown in FIG. 4, when the URL included in the access start information is “www.AAA.com/abc.html”, “www.AAA.com/abc.html” is obtained from the URLs of the keyword information k1, k2, and k5 shown in FIG. “BBB.com/def.html” and “www.CCC.com/ghi.html” are selected and match “www.BBB.com/def.html” or “www.CCC.com/ghi.html” Keyword information k2 to k7 shown in FIG. 3 are extracted as keyword information having a URL.

  Subsequently, the keyword acquisition unit 112 sorts the extracted keyword information in descending order of importance, selects keyword information having importance within a predetermined order from the top, and selects the search keyword of the selected keyword information as described above. Get as another keyword.

  This will be specifically described with reference to FIG. When the keyword information k2 to k7 shown in FIG. 3 is rearranged in descending order of importance, the keyword information k3, keyword information k4, keyword information k6, keyword information k7, keyword information k2, and keyword information k5 are arranged in this order. For example, when the predetermined order is set to the second place, “1000 yen, lunch” that is the search keyword of the keyword information k3 and “sushi, lunch” that is the search keyword of the keyword information k4 Acquired as a keyword.

  Here, the predetermined order can be arbitrarily set. For example, according to the size of the expression fluctuation that occurs when expressing the contents of the keyword, as the keyword with a larger expression fluctuation, the predetermined order is set to be larger so that the number of other keywords to be acquired is larger. Also good.

  By having such a keyword acquisition unit 112, when accessing any one of a plurality of Web pages accessible by keyword search, another search is performed in order to search for the remaining other Web pages. The keyword used by the user can be acquired as another keyword. In addition, it is possible to select and acquire only the keywords having high importance among other keywords.

  Note that the conditions for the keyword acquisition unit 112 to select keyword information are not limited to those in which the importance levels sorted in descending order are within a predetermined order. For example, it is good also as selecting what the importance sorted in descending order is more than a predetermined threshold.

  The search information providing unit 113 illustrated in FIG. 2 recommends the search result information obtained as a result of the search using the other keywords acquired by the keyword acquiring unit 112 and the keywords included in the access start information to the user. To the user terminal 20 as recommended information. The search target may be all Web servers on the Internet, or may be limited to Web servers belonging to a specific domain. The search destination information may be, for example, information stored in a keyword information database as shown in FIG. 3, or may be Web information or product information stored in another database. Good.

  The DB update unit 114 performs data analysis using the access start information, access end information, and mouse position information accumulated in the update database 120. For example, the DB update unit 114 performs data analysis as follows.

  First, the DB update unit 114 determines whether or not the mouse is operated on the user terminal 20 that has accessed the Web server 40. Whether or not the mouse is operated can be determined as follows. First, the coordinates of all mouse position information regarding the user terminal 20 acquired between the access start time of the access start information regarding the user terminal 20 and the access end time of the access end information are compared. Next, when all the coordinates match, it is determined that the mouse is not operated, and when there are coordinates that do not match, it is determined that the mouse is operated.

  Subsequently, when the DB update unit 114 determines that the mouse is not operated, the DB update unit 114 deletes the access start information, access end information, and mouse position information regarding the user terminal 20 used for the determination from the update database 120. Thereby, for example, information related to the keyword searched by the automatic search processing by the scheduler can be excluded from registration targets in the keyword information database 121. That is, when the mouse is not operated during access, it can be determined that access is performed by an automatic search by the scheduler, and information regarding the keyword can be excluded from registration targets. On the other hand, when the mouse is operated during access, it can be determined that the access is made by keyword search based on user input, and information related to the keyword can be registered.

  Subsequently, the DB update unit 114 normalizes the keywords of the access start information stored in the update database 120 using a known morphological analysis method, a syntax analysis method, or the like. When the DB update unit 114 determines that the keyword is an unknown keyword that is not listed in the dictionary, such as “Aa is aaa”, for example, The access start information and access end information including, and the mouse position information corresponding to the access start information and access end information are deleted from the update database 120. Thereby, for example, information regarding an unknown keyword can be excluded from registration targets in the keyword information database 121.

  The DB update unit 114 generates keyword information using the access start information and access end information stored in the update database 120 and registers this keyword information in the keyword information database 121. For example, the DB update unit 114 generates keyword information and registers it in the keyword information database 121 as follows.

  First, the DB update unit 114 calculates the browsing time using the access start information and the access end information. For example, when the access start information shown in FIG. 4 and the access end information shown in FIG. 5 are used as access start information and access end information that match the user ID, URL, and keyword, the access start time is “2008 / Since it is 08/31 12:01:10 and the access end time is “2008/08/31 12:06:10”, “00:05:00” is calculated as the viewing time. If keyword information with the same URL and keyword is already registered in the keyword information database 121, the average browsing time is calculated using the calculated browsing time and the average browsing time already registered. become.

  Subsequently, the DB update unit 114 calculates the importance using the calculated browsing time. For example, the importance is calculated so that the importance increases as the viewing time increases according to the viewing time. In addition, when the keyword information in which URL and a keyword correspond is already registered into the keyword information database 121, importance is calculated using average browsing time.

  In addition, the element used for calculating the importance is not limited to the browsing time. For example, the degree of importance may be calculated using the number of users who accessed the web page, the number of accesses, the degree of matching between the category to which the web page belongs and the content of the keyword, the access rate obtained as a response to providing recommendation information, and the like. The importance may be calculated by combining a plurality of these elements. Specifically, the importance can be calculated so as to increase as the number of users, the number of accesses, the degree of coincidence, and the access rate increase.

  Subsequently, the DB update unit 114 associates the URL included in the access start information, the normalized keyword included in the access start information, and the importance of the keyword with respect to the content of the Web page stored in the URL. Keyword information is generated, and this keyword information is registered in the keyword information database 121. If keyword information that matches the URL and the keyword is already registered in the keyword information database 121, the importance level and the average browsing time are changed and updated.

  The DB update unit 114 acquires this recommendation information when at least one of the URLs included in the recommendation information provided to the user terminal 20 by the search information providing unit 113 is selected by the user terminal 20. The importance value stored in the keyword information database 121 is increased in association with the other keywords used in the process. The value to be increased may be a predetermined value or a value corresponding to a predetermined ratio. Thereby, since the importance corresponding to the recommendation information selected by the user can be made high, it becomes possible to reflect a user's desired degree in importance.

  The control unit 11 physically includes, for example, a CPU, memories such as a ROM, a RAM, and an HDD that store various programs processed by the CPU and various data, and an input / output interface. These elements are connected to each other via a bus. The memory stores a search information providing program for realizing the same function as the control unit 11 shown in FIG. 2, and search information providing data stored in the storage unit 12 shown in FIG. Each component of the search information providing system 10 described above functions by the CPU executing the search information providing program and processing the search information providing data.

  Next, the operation of the search system including the search information providing system in the embodiment will be described with reference to FIGS. 6 and 7. FIG. 6 described first is a flowchart for explaining the procedure of the keyword information registration process. In this processing procedure, a procedure for registering keyword information in the keyword information database 121 will be described.

  First, in the user terminal 20 accessing the search Web page of the search site server 30, a search keyword is input by the user (step S101), and a search instruction by clicking a search button is input (step S102). The user terminal 20 transmits a search request based on the input keyword to the search site server 30 (step S103).

  Subsequently, the search site server 30 performs a keyword search using the keyword included in the search request received from the user terminal 20 (step S104). The search site server 30 generates a search result list Web page using the search information acquired by the keyword search, and transmits information on the Web page to the user terminal 20 (step S105). Thereby, the Web page including the search result list is displayed on the display screen of the user terminal 20 (step S106).

  Subsequently, when the user terminal 20 selects one URL included in the search result list and inputs an access instruction to the site corresponding to the URL (step S107), the user terminal 20 is selected. The web page of the web server 40 corresponding to the URL is accessed (step S108). Thereby, site information is transmitted from the web server 40 (step S109), and a web page including the site information of the web server 40 is displayed on the display screen of the user terminal 20 (step S110).

  On the other hand, the Web server 40 established with access to the user terminal 20 transmits access start information related to the user terminal 20 to the search information providing system 10 (step S111). The Web server 40 acquires the mouse position information of the user terminal 20 at any time while the user terminal 20 continues to access (step S112), and transmits the acquired mouse position information to the search information providing system 10. (Step S113).

  Subsequently, when an instruction for returning to the search result list is input by the user at the user terminal 20 (step S114), the user terminal 20 accesses a Web page of the search result list of the search site server 30 (step S115). ). As a result, information on the search result list Web page is transmitted from the search site server 30 (step S116), and the search result list Web page is displayed on the display screen of the user terminal 20 (step S117).

  On the other hand, the Web server 40 that has been disconnected from the user terminal 20 transmits access end information related to the user terminal 20 to the search information providing system 10 (step S118).

  The DB update unit 114 of the search information providing system 10 performs data analysis using the access start information, mouse position information, and access end information received from the Web server 40 and accumulated in the update database 120 (step S119). , Generate keyword information. The DB update unit 114 of the search information providing system 10 registers the generated keyword information in the keyword information database 121 and updates the database (step S120).

  FIG. 7 to be described next is a flowchart for explaining the procedure of the recommendation information providing process. In this processing procedure, a procedure for providing recommendation information to the user terminal 20 will be described. Note that the processing contents from step S201 to step S208 shown in FIG. 7 are the same as the processing contents from step S101 to step S108 shown in FIG. Therefore, in this processing procedure, description of the above processing content that overlaps is omitted, and processing procedures after step S209 in which the processing content is different will be described.

  In step S208, the Web server 40 that has established access with the user terminal 20 transmits access start information regarding the user terminal 20 to the search information providing system 10 (step S209).

  Subsequently, the keyword acquisition unit 112 of the search information providing system 10 uses the keyword included in the received access start information to extract another keyword different from this keyword from the keyword information database 121 (step S210).

  Subsequently, the search information providing unit 113 of the search information providing system 10 performs a keyword search using the other keywords extracted in step S210 and the keywords included in the access start information (step S211).

  Subsequently, the search information providing unit 113 of the search information providing system 10 transmits the search information obtained by the keyword search in step S211 to the web server 40 in order to provide the user terminal 20 as recommendation information (step S212). ). The web server 40 that has received the recommendation information transmits the recommendation information to the user terminal 20 (step S213). Thereby, the Web page including the recommendation information is displayed on the display screen of the user terminal 20 (step S214).

  Subsequently, in the user terminal 20, when one URL included in the recommendation information is selected by the user and an instruction to access a site corresponding to the URL is input (step S215), the user terminal 20 is selected. The web page of the web server 40 corresponding to the URL is accessed (step S217). Thereby, browsing information indicating that information included in the recommendation information has been browsed is transmitted from the Web server 40 accessed by the user terminal 20 to the search information providing system 10 (step S217).

  Subsequently, the DB update unit 114 of the search information providing system 10 updates the keyword information database 121 by increasing the importance value corresponding to another keyword used when acquiring the recommendation information corresponding to the browsing information. (Step S218).

  As described above, in the search system 1 having the search information providing system 10 of the present embodiment, the user terminal 20 is input when accessing one Web page searched by the keyword input in the search Web page. Other keywords that are different from the keywords and that are determined to have high importance in other Web pages that can be searched with the input keyword are acquired from the search keywords stored in the keyword information database 121. The user terminal 20 can be provided with search information obtained as a result of a search using the acquired other keyword and the keyword input to the search Web page.

  That is, it is possible to execute a search using a keyword having a high degree of importance among keywords input by other users in order to search a Web page related to a Web page selected by a user by keyword search. The search information obtained as a result of the above can be provided to the user. As a result, regardless of the level of the search technique, the search accuracy can be improved and the information desired by the user can be provided accurately.
