Description

  The present invention provides an information search system, an information search device, and search result screen information generation for searching for presentation information in response to a request from a terminal device that acquires presentation information to be presented to a user from a server device via a network. The present invention relates to a technical field of a method and a search result screen information generation processing program.

  Conventionally, a network is provided via a hyperlink (hereinafter simply referred to as “link”) provided in a network such as the Internet and embedded in a Web page or the like described in a markup language such as HTML (Hyper Text Markup Language). 2. Description of the Related Art Hypertext systems such as WWW (World Wide Web) that enable browsing of various information resources to be presented to a user such as web pages, image data, and document data scattered on the top are widely known.

  In such a hypertext system, a user accesses a search site such as Google (registered trademark), Yahoo (registered trademark), Infoseek (registered trademark) using a terminal device such as a personal computer, and is scattered on the network. It is a common practice to search for necessary information resources from various information resources.

  The server device of the search site performs a search process using a keyword input by the user in response to a request from the terminal device, and displays a Web page in which a link to the searched information resource is embedded as a search result. When transmitted to the device, the search result is displayed by the terminal device that has received the Web page. Then, when the user instructs acquisition of the searched information resource, for example, by clicking a link embedded in the Web page with a mouse, the terminal device displays the server device of the Web site that provides the information resource. To access.

  In addition, among the search sites described above, there are sites that provide statistical information such as the number of searches performed so far and the number of times the user has been instructed to access information resources (acquisition of information resources) as statistical information. To do.

  For example, in Google (trademark), information such as the ranking of keywords with a high number of search requests and the ranking of Web pages with a high number of accesses (clicks) from a Web page displaying search results. Is provided as statistical information for each user.

Further, as an invention related to the present invention, for example, in Patent Document 1, the number of times of designation for each keyword is stored in a database, and when a keyword is designated by a user, a search is performed with the keyword and the same classification An invention is disclosed in which a re-search is performed with the keyword and the result of the re-search is preferentially displayed for a keyword having a larger number of specified times.

  However, in Google (trademark), the ranking that associates the keyword with the number of times the user has instructed access is not displayed, and each ranking is simply provided as statistical information. For a user who wants to specify a Web page with a keyword, the information is not sufficient to determine the Web page to be accessed. In other words, regardless of the keyword used for the search, the Web page with the highest number of accesses is simply displayed, so that even the Web page shown at the top of the ranking is displayed. It is not certain whether this Web page is displayed at the top as a result of a previous search with a keyword that is to be used for the search. Therefore, the user cannot determine whether or not the Web page displayed at the top may be accessed.

  In addition, since statistical information about other users is not displayed, but only statistical information about what the user himself has performed a search operation is displayed, this statistical information is used when determining a Web page to be accessed. It was not so helpful information. Furthermore, since this statistical information is provided on a Web page different from the Web page of the search result, there is a problem that an operation for browsing the statistical information becomes complicated.

  Specifically, the system control unit 20 serving as the access count calculating means stores all or all the search word histories in which the same search word as the search word used in the current search process is set for a predetermined period ( For example, the search is made up to one month). Next, the system control unit 20 acquires the URL and title of the information resource accessed in the past from the search access history corresponding to each searched word history. Since the search access history is created corresponding to one access (reception of one access notification), the system control unit 20 sets one search access history as one access count and sets the total access count for each URL. It is calculated for each information resource. However, the system control unit 20 calculates the number of accesses for each user, with a plurality of accesses to the same information resource as one access.

  Then, the system control unit 20 as ranking information generating means determines the ranking of information resources in descending order of the number of accesses, and creates an access ranking from the first rank to a predetermined rank. At this time, the system control unit 20 creates a link (an URL of the information resource is embedded: an example of link information) that displays the title of the information resource of each rank.

  Further, the system control unit 20 as a search result screen information transmitting unit transmits the search result page 200 in which the access ranking is embedded to the user terminal 4-k that has transmitted the search request.

  Further, the system control unit 20 as an access instruction notification receiving unit activates the user terminal 4-k by activating an event handler when a link for displaying a title is selected by the user through the search result page 200. An access notification transmitted from the terminal 4-k is received.

  The information search server 1 manages the member information registered in the member information database 101 by managing various member information registered in the member information database 101 based on information registered in various databases. A member information management server that performs processing such as changing member information, a search site based on a variety of information managed by other servers, and a plurality of server devices such as a WWW server that provides various information Also good.

FIG. 7 is a flowchart showing the flow of processing in search page creation processing of the system control unit 20 of the information search server 1 according to the present embodiment.

  First, when the user operates the user terminal 4-k to designate a predetermined URL, as shown in FIG. 6, a login request is transmitted from the user terminal 4-k to the information search server 1 (steps). S1) With this as a trigger, a login process is performed between the user terminal 4-k and the information search server 1 (step S2). Specifically, a login page is transmitted from the information search server 1 to the user terminal 4-k, and a member ID and a password input by the user through the login page are transmitted from the user terminal 4-k to the information search server 1.

  Then, password authentication is executed in the information search server 1, and when the password authentication is successful, the information search server 1 transmits a search page to the user terminal 4-k together with the cookie in which the user's member ID is set (step). S3).

  The user terminal 4-k that has received the cookie and the search page stores the cookie and displays the search page on the screen. This search page is provided with an input area for inputting a search word, a button for selecting a search type, a search button, and the like. When the user inputs a search word and selects a search button (step S4), the user terminal 4-k transmits a search request in which the search word and the search type are set to the information search server 1 (step S5). ).

  The information search server 1 that has received the search request executes a search process (step S6). Specifically, the information search server 1 searches the search database 102 for the type of information resource indicated by the search type using the search word set in the request. The information retrieval server 1 then retrieves the search number. Is newly assigned and the search number is assigned. The search word history is created based on the search word set in the search request, and the search word history is transmitted as a cookie when the user member ID (user terminal 4-k transmits the request). It is registered in the search word database 103 in association with the member ID (the same applies hereinafter).

  Next, the information search server 1 executes a search page creation process (step S7). In this search page creation process, the information search server 1 creates a search result page 200 based on the search result, creates an access ranking, and embeds the access ranking in the search commission result page 200. Details of the search page creation process will be described later.

  Next, the information search server 1 transmits the created search result page 200 to the user terminal 4-k (step S8).

  The user terminal 4-k that has received the search result page 200 displays the page on the screen as shown in FIG.

  The search result page 200 includes a search bar 210, a search result display area 220, an access ranking display area 230, and the like.

  The search bar 210 is provided with an input area for inputting a search word, a tab for specifying a search type and performing a search, a search button, and the like. In the input area, the search word input in step S4 is stored. It is displayed as the default search word.

  In the search result display area 220, a list of searched information resources is displayed. Specifically, for each searched information resource, information such as the title, summary, URL, data size, and last update date / time is displayed for 10 items, for example. The display order of the search results in the search result display area 220 is determined based on a predetermined criterion.

  In the access ranking display area 230, an upper information resource list 231 and a ranking detail link 233 are provided. The upper information resource list 231 displays a list of information resources from the first rank to the predetermined rank in the access ranking based on the search word input by the user. When one of the links 232 for displaying the title of the information resource is selected by the user in the upper information resource list 231, the user terminal 4-k identifies the information resource specified by the URL embedded in the link. To access. At this time, the user terminal 4-k does not transmit an access notification.

  When the ranking detail link 233 is selected, the access ranking page displays a list of information resources that are lower than the predetermined order displayed in the upper information resource list 231 (for example, first to 100th). Transition.

  Here, in the search result display area 220, when the user selects any one of the links 221 for displaying the searched information resource titles (step S9), the user terminal 4-k selects the selected link. By starting the event handler associated with the URL, an access notification is transmitted to the information search server 1 (step S10), and the information resource specified by the URL embedded in the link is accessed (domain in the URL) An information resource request is transmitted to the Web server 3-j indicated by the name) (step S11). As a result, the requested information resource is transmitted from the Web server 3-j to the user terminal 4-k.

  On the other hand, the information search server 1 that has received the access notification executes a search access history registration process (step S12). Specifically, the system control unit 20 searches for the search number set in the access notification. The search access history is created based on the URL, title, summary, etc., and the access history is registered in the history database 104 in association with the member ID of the user.

  Next, the search result page creation process shown in step S7 of FIG. 5 will be described.

  When the search process is completed, the system control unit 20 of the information search server 1 stores an HTML data template for the search result page 200 (data serving as a template for HTML data of the search result page 200) as shown in FIG. 15 (step S51), a search result (a list of searched information resources, etc.) is embedded in the HTML data template (step S52).

  Next, the system control unit 20 identifies one of all users other than the user who requested the search from among the registered users (step S53).

  Next, the system control unit 20 searches the search word database 103 for a search word history in which the member ID and search word that are the same as the specified user ID and the input search word are set (step S54). It is determined whether or not there is a corresponding search word history (step S55). At this time, if there is no corresponding search word history (step S55: NO), the system control unit 20 proceeds to step S66.

  On the other hand, if there is a corresponding search word history (step S55: YES), the system control unit 20 specifies one of the searched search word histories (step S56).

  Next, the system control unit 20 searches the history database 104 for a search access history corresponding to the specified search word history (step S57). That is, the system control unit 20 sets the member ID and the search number set in the specified search word history. And the same member ID and search number. Search the search access history for which is set.

  Next, the system control unit 20 determines whether there is a corresponding search access history (step S58). That is, the search word history is created in the search process (step S6 in FIG. 5) regardless of whether or not the searched information resource is accessed, while the search access history corresponding to this search word history is: Since it is created for the first time when the access notification transmitted from the user terminal 4-k is received through the search result page 200 (step S12 in FIG. 5), even if the search word history is registered, the search access history corresponding thereto In some cases, the system control unit 20 determines whether there is a search access history corresponding to the search word history in step S55.

  At this time, if there is no corresponding search access history (step S58: NO), the system control unit 20 leaves the search access history although the specified user has performed a search using the corresponding search word. If not, the process proceeds to step S63.

  On the other hand, if there is a corresponding search access history (step S58: YES), the system control unit 20 determines whether the URL set in this search access history is a URL already entered in the access ranking. (Step S59). If the URL has already been entered (step S59: YES), the process proceeds to step S61.

  On the other hand, if the URL is not already entered (step S59: NO), the system control unit 20 registers a new entry (step S60). Specifically, the system control unit 20 newly sets an entry storage area on the storage area of the RAM 19, and sets the URL and title set in the searched search access history in the entry storage area. , 0 is set as the number of accesses. After completing this process, the system control unit 20 proceeds to step S61.

  In step S61, the system control unit 20 determines whether or not the URL set in the searched search access history is registered in the access URL list. The access URL list is information indicating a list of URLs of information resources for which access has been instructed in the past by the specified user, and the storage area is set on the storage area of the RAM 19. At this time, if the URL set in the searched search access history is registered in the access URL list (step S61: YES), the system control unit 20 proceeds to step S63.

  On the other hand, if the URL set in the retrieved search access history is not registered in the access URL list (step S61: NO), the system control unit 20 is set in the retrieved search access history. When the URL is registered in the access URL list (step S62), the process proceeds to step S63.

  In step S63, the system control unit 20 determines whether or not URL checking (the processing in steps S56 to S62) has been performed for all of the retrieved search word histories (step S63), and the URL is being checked. If there is no search word history (step S63: NO), the process proceeds to step S56, the next search word history is specified, and the URL is checked. As a result, the search access history for the search word requested by the specific user is all examined.

  When the URL is checked for all searched search word histories (step S63: YES), the system control unit 20 accesses the number of entries corresponding to each URL registered in the access URL list. 1 is added to (step S64). As a result, for the information resource instructed to be accessed by one identified user, the number of accesses will be added as one, no matter how many times the access is instructed.

  Next, the system control unit 20 clears the access URL list, that is, deletes all URLs registered in the access URL list, the process proceeds to step S66.

  In step S66, the system control unit 20 determines whether or not the access count addition processing (the processing in steps S53 to S65) has been performed for all users other than the user who requested the search, and the access count addition processing is performed. When there is an unidentified user (step S66: NO), the process proceeds to step S53, the next user is specified, and the access count adding process is performed.

  Then, when the access count addition processing is performed for all users other than the user who requested the search (step S66: YES), the system control unit 20 arranges the registered entries in the order of increasing access count ( In step S67, an access ranking is created based on the entries from the first rank to the predetermined rank among the arranged entries (step S68). Specifically, the system control unit 20 displays the title set for this entry for each entry from the first place to the predetermined order, and the link 232 with the URL set for the entry as a link destination. Create etc.

  Next, when the search result page 200 is created by embedding the created access ranking in the HTML data template in which the search result is embedded (step S69), the system control unit 20 ends the search result page creation process.

  As described above, according to this embodiment, the system control unit 20 of the information search server 1 has been searched in the past using the same search word as the search word used for the current search, and this time The number of accesses, which is the number of accesses for each information resource accessed by the user terminal 4-k used by a user other than the user who entered the search word used for the search, is calculated, and the calculated access An access ranking indicating information resources whose ranks are ranked in descending order from the first rank to a predetermined rank is created, and a search result page 200 including a display of the created access ranking is created.

  Therefore, unlike ranking based on the number of accesses that are not related to the search word, access to information resources that are searched with the same search word as the search word used for the current search and that are frequently accessed by other users The user can browse more reliable information called ranking. In other words, the information resource shown in the access ranking is an information resource that has been accessed with the same search word as the search word entered by the user, so that many other users can access it with the same keyword. If this is the case, the user can go to the information resource ranked higher as an information resource with a high possibility of being satisfied.

  In addition, since this access ranking is displayed on the screen based on the search result page 200 together with the current search result, there is no need to perform an extra operation for browsing the access ranking.

  Further, the system control unit 20 of the information search server 1 is accessed by many users by calculating the number of times of access by making multiple accesses to the same information resource by the same other user as one access. Since the information resources are surely ranked higher, the user can browse information with higher reliability.

  In addition, when the user selects a link for displaying the title of the upper information resource displayed in the access ranking display area 230 of the search result page 200, the user terminal 4-k can receive information corresponding to the selected link. Since resources are accessed, it is possible to easily access information resources ranked higher.

  In the above embodiment, the access count is calculated as a single access for a plurality of accesses to the same information resource by the same user. However, this multiple access is directly reflected in the access count. May be.

  In the above embodiment, the history service cannot be used unless the user is registered as a member of the information search system S. However, even if the user is not a member of the information search system S, the history service can be used. It may be possible. In this case, for example, the information search server 1 transmits a cookie in which unique identification information is set to the accessing user terminal 4-k and stores the cookie in the user terminal 4-k. It ’s fine. As a result, each time a request from the user terminal 4-k is transmitted, the cookie is also transmitted. Therefore, the search access history can be registered in accordance with the identification information set in the cookie. I can do it. Since information regarding access to information resources can be obtained from more users, a more reliable access ranking can be created.

  In the above embodiment, the access ranking is created using the search access history when creating the search result page 200 corresponding to the request from the user terminal 4-k. It may be provided separately and the access ranking registered in the database may be updated each time an access notification is received from the user terminal 4-k. By doing so, it is not necessary to search the search word history of all users every time there is a search request (step S53 to step S66 in FIG. 7).
