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 a Web page (hereinafter referred to as a search result) in which a link to the searched information resource is embedded. , Referred to as a search result page), 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.

  When a large number of information resources are searched in the search process, the search result cannot be displayed on one screen in the terminal device.

M) as an example of a server device. And a plurality of user terminals 4-k (k = 1, 2,... N) as an example of a terminal device.

  The information search server 1, the Web server 3-j, and the user terminal 4-k transmit / receive data to / from each other using, for example, TCP / IP (Transmission Control Protocol / Internet Protocol) as a communication protocol via the network NW. Is possible. The network NW is constructed by, for example, the Internet, a dedicated communication line (for example, a CATV (Community Antenna Television) line), a mobile communication network (including a base station), a gateway, and the like.

  In the information search system S having such a configuration, the information search server 1 is a server device installed to open a search site by a service provider that provides various services through the network NW.

  This information search system S uses a user terminal 4-k as a service for searching for information resources (an example of presentation information) existing in the network NW such as Web pages, blogs, still image data, moving image data, software, and news. It is designed to be provided to users who want to.

  In order to provide such a service, the information search server 1 includes a member information database 101, a search database 102, a search word database 103, a history database 104, a label database 105, and an evaluation item database 106 as examples of databases. . In the information search system S, the information search server 1 performs a search process in response to a request from the user terminal 4-k via the network NW, and displays a list of information resources searched as a result of the search process. A search service is provided to the user by transmitting a search result page 200 to be described later (see FIGS. 6 and 7: an example of search result screen information) to the user terminal 4-k.

  In addition, the information search system S is configured to record a history of access by the user terminal 4-k to the information resource selected by the user through the search result page 200 as a search access history. A history service is also provided.

  In order to use this history service, the user needs to perform a membership registration procedure of the information search system S in advance (hereinafter, a user who can use the history service is referred to as a “member”). By becoming a member of the information search system S, the user himself / herself performs a search operation using the user terminal 4-k, the search word that is the keyword used for the search, the URL of the information resource, Search access history such as title, summary, number of accesses, visit date, etc. can be viewed. The search service itself can be used without performing the membership registration procedure.

  In the history service, a label for displaying a name set by the user can be attached to the search access history (a label can be associated with the search access history). The same label is attached to the search access history having the same URL of the information resource. Then, the user can browse the label pasted together with the search access history.

  As a usage mode of this label, for example, it is assumed that the label is pasted as a memo so that it is not forgotten, the search access history is easy to see, or the search access history is classified by the label.

  In addition, the information search server 1 assumes that the information resource that has reached the preset number of times from the user terminal 4-k through the search result page 200 is an information resource that is frequently accessed. The link is displayed in a frame different from the search result displayed on the search result page 200. The number of accesses is calculated for each user, and even when the same information resource is accessed, if the search word used for the search is different, each access count is calculated separately. Yes.

  Next, the Web server 3-j is a server device that provides information resources such as a Web page corresponding to the requested URL to the accessing user terminal 4-k. The information search server 1 has a so-called robot-type search engine, and periodically collects information resources provided by the Web server 3-j from the Web server 3-j in order to enable keyword search. The search database 102 is constructed based on the collected information resources.

  Next, the user terminal 4-k is a terminal device that is used by the user to access the information search server 1, acquire a Web page, display it on the screen, and use a search service, a history service, and the like through the Web page. For example, a personal computer, a PDA (Personal Digital Assistant), an STB (Set Top Box), a mobile phone, or the like in which a Web browser application or an e-mail application is installed can be applied.

  First, as shown in FIG. 3, in the member information database 101, member information relating to a member of the information search system S is registered in association with a member ID for identifying the member. Specifically, the member information includes, for example, a member ID, a password for logging in, a member's name, postal code, address, telephone number, e-mail address, date of birth, gender, credit card number and its validity. A deadline, a nickname, a separate frame display setting access count (an example of the set count), and the like are set.

  Here, the separate frame display setting access count is a frame (a later-described multi-access) that is different from a frame (a later-described search result display area 220) that displays a link to an information resource accessed through the search result page 200. This is information indicating the number of accesses as a condition to be displayed in the information resource display area 230). This separate frame display setting access number can be changed by the user's selection, and is set to 5 times as an initial value, for example.

  Next, in the search database 102, as a result of analyzing the information resources collected from each Web server 3-j, the URL of the information resource (an example of presentation information specifying information), title (for example, HTML (HyperText Markup (Language) Web page name described in the header of the data), URL, summary (for example, description and summary of the Web page described in the header of the HTML data, part of the text described in the body part, etc.) ), Index information including keywords and the like is registered.

  Next, as shown in FIG. 4A, in the search word database 103, the search word history related to the search word used for the search is registered in association with the member ID of the member who performed the search operation. ing. Specifically, the search word history includes a search number indicating a member ID and a number assigned for each search of the member. (An example of keyword identification information), a search word that is a keyword used in the search (an example of keyword information), a search type that indicates the type of information resource that has been searched (for example, Web page, still image data, video data, Blog, etc.), the number of searches indicating the number of searches using the same search word, and the search date and time are set.

  Next, as shown in FIG. 4B, in the history database 104, the search access history is registered in association with the member ID of the member who performed the search operation for each access to the information resource.

Specifically, the search access history includes a member ID and a history No. indicating a number assigned to each member's search access history. , Corresponding search word history search No. , URL of the information resource accessed by the user terminal 4-k, title, summary, number of accesses, visit date / time (access date / time), comment input by the member for the information resource, paste to the search access history A label ID for identifying a given label, an evaluation item ID for identifying an evaluation item set by the member for the information resource, and an evaluation (for example, five-step evaluation) by the member in the evaluation item are set. The

  Next, as shown in FIG. 4C, in the label database 105, label management information related to the label registered by the member is registered in association with the member ID of the member. Specifically, the label management information includes a member ID, a label ID, and a label name that is a name set for the label.

  Next, as shown in FIG. 4D, in the evaluation item database 106, evaluations regarding evaluation items registered by the members themselves so that the members can evaluate the information resources accessed through the search result page 200. Item management information is registered in association with the member ID of the member. Specifically, in the evaluation item management information, a member ID, an evaluation item ID for identifying an evaluation item set by the member for the resource information, and an evaluation item name that is the name of the evaluation item are set.

  Furthermore, in addition to a predetermined operating system, the storage unit 15 uses the HTTP (Hyper Text Transfer Protocol) protocol to store the request in the storage unit 15 in response to a request transmitted from the user terminal 4-k or the like. A WWW (World Wide Web) server program for generating a Web page based on various types of data and transmitting the Web page to the user terminal 4-k, etc., using the SMTP (Simple Mail Transfer Protocol) protocol, While receiving the e-mail transmitted from the mail server, the mail server program for transmitting the e-mail created in the information search server 1 to another mail server, the member information database 101, and the information search system S Manage member information and process member registration, withdrawal (deletion of registration), change of member information, etc. Member information management program for executing, (an example of the search result screen information generating process program) search program for performing various processes for the search of information resources and the like are stored.

  Various programs may be acquired from, for example, another server device via the network NW, or may be recorded on a disk DK such as a CD-ROM and read via the drive unit 14. Anyway.

  In this embodiment, the system control unit 20 is an example of keyword information receiving means, search means, search result screen information generation means, access count calculation means, access information generation means, search result screen information transmission means, and access instruction notification reception means. Is configured.

  The system control unit 20 controls each unit of the information search server 1 by the CPU 17 reading and executing various programs stored in the ROM 18 and the storage unit 15 and functions as the above-described units. ing.

  The function as each means will be described. The system control unit 20 as the keyword information receiving means and the searching means receives the search request in which the search word input by the user is set from the user terminal 4-k, and By performing a search process on the search database 102 using the search word set in the request, information resources matching the search word are searched.

  Further, the system control unit 20 as the search result screen information generation unit creates the search result page 200 based on, for example, the search results of the first 10 items (an example of the number of set items) among the search results in the search process. It is supposed to be. Specifically, the system control unit 20 creates a search result page 200 that displays a list of links (an example of search result link information), summaries, and URLs that display the titles of searched information resources. Yes.

  When creating this search result page, the system control unit 20 embeds the URL of the corresponding information resource in each link displaying a title, and responds to the selection of the link by the user with an event handler (for example, , A description for starting up (described in a search result page by a script language such as JAVA (registered trademark) script) is embedded.

  This event handler notifies the user terminal 4-k that the user terminal 4-k has been instructed to access the information resource corresponding to the selected link by selecting the link for displaying the title by the user. This is a program for transmitting an example of access instruction notification information to the information search server 1. This access notification includes the search number embedded in the search result page. Information such as URL, title, and summary of the information resource to be accessed is set.

  In addition, the system control unit 20 includes the current search resource in the past search process using the same search word as the search word (search word input by the user) used in the current search process. The number of accesses from the user terminal 4-k by the user who requested the search processing being instructed to access the user terminal 4-k used by the user through the search result page 200 is the number of separate frame display setting access. The information resource that has been reached is embedded in the search result page 200 as a multi-access list (an example of access information).

  Specifically, the system control unit 20 as the access count calculation means sets the user ID of the user who requested the current search, and sets the same search word as the search word used for the current search process. The search word history is searched for all or a predetermined period (for example, one month) retroactively. 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.

  Then, the system control unit 20 as an access information generation unit identifies information resources whose access count has reached the separate frame display setting access count set in the member information of the user who requested the current search, Create a list. At this time, the system control unit 20 creates a link that displays the title of each information resource that has reached the separate frame display setting access count (the URL of the information resource is embedded: an example of link information). The system control unit 20 creates the search result page 200 using the search results excluding the search results related to the information resources that have reached the separate frame display setting access count.

  Further, the system control unit 20 as a search result screen request receiving unit receives a next search result request (an example of search result screen request information) transmitted from the user terminal 4-k through the search result page 200. In response to the request, the search result page 200 displaying the search results for the eleventh and subsequent items is generated and transmitted to the user terminal 4-k.

  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.

[3. Operation of information retrieval system]
Next, the operation of the information search system S will be described with reference to FIGS. FIG. 5 is a sequence diagram illustrating a processing flow of the information search system S according to the present embodiment. 6 and 7 are diagrams showing display examples of the search result page 200. FIG. FIG. 8 is a flowchart showing a process flow in the search page creation process 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, a multi-access information resource display area 230, a next search result display link 240, 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.

  A multiple access list 231 is displayed in the multiple access information resource display area 230. The multi-access list 231 displays a link 232 for displaying the title of the information resource whose access count has reached the separate frame display set access count, and a list of the access counts. When one of the links 232 for displaying the title of the information resource is selected by the user, the user terminal 4-k accesses the information resource specified by the URL embedded in the link. At this time, the user terminal 4-k does not transmit an access notification.

  Further, for the information resource whose title is displayed in the multi-access list 231, the search result is not displayed in the search result display area 230. For example, in the search result page 200 shown in FIG. 6, the search result display area 230 displays the search result “XX market” as a result of the search using the search word “shopping”. Thereafter, after the number of times of searching for the site “XX Market” by searching for the same search word “shopping” reaches, for example, 5 times as the number of separate frame display setting accesses, as shown in FIG. While “XX market” is displayed in 231, the search result of “XX market” is not displayed in the search result display area 230.

  The next search result display link 240 is displayed when the number of searched information resources exceeds one page (for example, 10). When the next search result display link 240 is selected by the user, the user terminal 4-k transmits a next search result request to the information search server 1, and the information search server 1 responds to the 11th to 20th cases. A search result page 200 for displaying the search results is created and transmitted to the user terminal 4-k, and the user terminal 4-k displays the received search result page 200 on the screen. Here, when the next search result display link 240 is selected, the next transition is made to the search result page 200 displaying the 21st to 30th search results.

  The search result display area 230 is provided on the search result page 200 that is displayed first after the search process is performed (the search result page 200 that displays the first to tenth search results). It is arbitrary whether or not the search result page 200 is provided on the search result page 200 displayed in response to the selection of the subsequent search result display link 240 thereafter.

  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 processing is completed, the system control unit 20 of the information search server 1 sets the member ID and the search word that are the same as the member ID of the user who requested the search and the input search word, as shown in FIG. The search word history is searched from the search word database 103 (step S51), and it is determined whether there is a corresponding search word history (step S52). At this time, if there is no corresponding search word history (step S52: NO), the system control unit 20 (that is, the specified user has performed a search with the corresponding search word, but the search access history is not stored). If not, go to step S64.

  On the other hand, when there is a corresponding search word history (step S52: YES), the system control unit 20 specifies one of the searched search word histories (step S53).

  Next, the system control unit 20 searches the history database 104 for a search access history corresponding to the specified search word history (step S54). 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 S55). 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 the case 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 corresponding thereto Since the history may not be registered, the system control unit 20 determines in step S55 whether there is a search access history corresponding to the search word history.

  At this time, if there is no corresponding search access history (step S55: NO), the system control unit 20 proceeds to step S59.

  On the other hand, if there is a corresponding search access history (step S55: YES), the system control unit 20 determines whether the URL set in the search access history is a URL already entered in the access list. (Step S56), and if the URL has already been entered (step S56: YES), the process proceeds to step S58.

  On the other hand, if the URL is not already entered (step S56: NO), the system control unit 20 registers a new entry (step S57). 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 S58.

  In step S58, the system control unit 20 adds 1 to the access count of the entry of the URL set in the searched search access history.

  Next, the system control unit 20 determines whether or not the URL check (the processing of steps S53 to S58) has been performed for all of the retrieved search word histories (step S59), and the search for which no URL check has been performed. When the word history exists (step S59: NO), the process proceeds to step S53, 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 user is all examined.

  If the URL is checked for all searched search word histories (step S59: YES), the system control unit 20 acquires the number of separate frame display setting accesses from the member information of the user who requested the search. (Step S60).

  Next, the system control unit 20 creates a multiple access list (step S61). Specifically, the system control unit 20 refers to the access count of each registered entry, and specifies all entries whose access count is greater than or equal to the acquired separate frame display setting access count. Then, the system control unit 20 displays the title set in the specified entry, and creates a link 232 having the URL set in the entry as a link destination.

  Next, when the system control unit 20 obtains an HTML data template for the search result page 200 (data serving as a template for HTML data of the search result page 200) from the storage unit 15 (step S62), the system control unit 20 makes multiple accesses to the HTML data template. The list is embedded (step S63).

  Next, the system control unit 20 acquires, for example, the search results for the top 10 items in the search results (a list of searched information resources, etc.) in the search process (step S64). At this time, the system control unit 20 acquires, for example, 10 search histories related to URLs set in entries that are equal to or greater than the number of separate frame display setting accesses, from the acquisition target.

  Next, when the search result page 200 is created by embedding the acquired search results in the HTML data template (step S65), the system control unit 20 ends the search result page creation process.

  As described above, according to the present embodiment, the system control unit 20 of the information search server 1 uses the same search word as the search word used for the current search among the information resources searched in the past. The number of accesses for each information resource accessed by the user terminal 4-k used by the user who has input the search word used for the current search is calculated, and the information accessed more than the number indicated by the separate frame display setting access number A multi-access list indicating the information resource including a link to the resource is generated, and a search result page 200 including a display of the generated multi-access list is generated. Then, the search result page 200 is transmitted from the information search server 1 to the user terminal 4-k, the search result and the multiple access list are displayed on the screen based on the search result page 200, and the links included in the multiple access list When the user selects, the user terminal 4-k accesses the information resource indicated by the URL included in the selected link.

  Therefore, by selecting a link included in the multiple access list displayed on the screen together with the search result by the keyword inputted this time, the user is searched with the same keyword as the keyword in the past and accessed by the user. It is possible to quickly access information resources that are frequently accessed.

  In addition, when the information resources that have been accessed so far are not displayed in the first 10 search results immediately after the search, for example, it is not possible to know what number is displayed. Is displayed, so that quick access to information resources that have been accessed so far can be realized more effectively.

  In addition, since the search result of the information resource shown in the multi-access list is not displayed in the search result display area 220, the information resource can be accessed quickly and unnecessary search results are not displayed. Other information resources not shown in the access list can be quickly accessed. In particular, since unnecessary search results are not displayed, a search history of another information resource that has not been displayed on one page is newly displayed, so that the information resource can be accessed quickly. .

  In addition, if there is a change in the search engine specification due to a change in the database specification or program change, the order of the information resources displayed in the search results may change before and after the specification change, Although it may be difficult to find the target information resource from the search result page 200, links of information resources that have been accessed so far can be quickly found by displaying a multi-access list.

  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.

  In the above embodiment, the number of accesses to each information resource is calculated when the search result page 200 corresponding to the request from the user terminal 4-k is created. For example, when the search access history is registered (see FIG. 5 Step S12) If the number of accesses to be set in this search access history is calculated and set separately for each search word used for the search, when the search result page 200 is created (particularly FIG. 8). In steps S56 to S58), the number of accesses set in the latest search access history for each information resource can be used as it is for comparison with the number of separate frame display set accesses (details are omitted, but in the above embodiment) The total number of accesses to the information resource is set as the number of accesses regardless of the search word).
