Description

  The present invention relates to an information search system and an information search method, and more particularly to an information search system and an information search for searching a database based on a keyword input from a terminal and outputting and displaying the search result on a terminal. Regarding the method.

  Conventionally, keyword search is known as one of means for extracting desired information from a database. In this method, a predetermined keyword related to information to be extracted is input on a terminal, and information including the keyword is searched from a database.

  In such a keyword search, when there are a plurality of pieces of matching information (such as documents) including the keyword, the information is output and displayed in the order stored in the database. Therefore, when the number of matching information in the keyword search is enormous, it becomes extremely complicated and difficult to select necessary information from among them, which not only increases the burden on the user but also provides necessary information. It takes a long time to get.

For this reason, in recent years, search results (conformance information) are rearranged and displayed in descending order of the number of keywords (for example, refer to Patent Document 1), or search results of Web pages including keywords input from a client terminal Has also been proposed to change the display order based on access status information in the client terminal for the Web page of the search result (see, for example, Patent Document 2). It has also been proposed to determine the display order of search results based on the number of links to the search results (weighting of matching information based on the number of links).
JP-A-4-252376 JP 2003-178092 A

  However, in the method of Patent Document 1 in which search results are ranked higher on the basis that the number of keywords is simply large, only information packed with keywords is displayed as higher-level information as matching information. However, the ordering is not always satisfactory, and the required information cannot be obtained quickly and efficiently.

  Further, in the method of Patent Document 2 in which the display order of search results of Web pages including keywords input from a client terminal is changed based on access status information in the client terminal, the Web based on the access results of the client terminal is used. As a result, only the pages are displayed at the top, the order reflecting the trend is not necessarily performed, and useful information reflecting the trend is not always obtained efficiently.

  On the other hand, in the method of determining the display order of the search results based on the number of linked links to the search results, the order that reflects the current trend can be given to some extent, but the Web page linked to the Web page that becomes the search result In some cases, it takes time until the production of the web page and time until the search engine grasps the information of the Web page, and it is impossible to make an order that immediately reflects the latest fashion.

  The present invention has been made in view of such circumstances, and provides an information search system and an information search method capable of efficiently searching and providing useful information reflecting a trend to users. With the goal.

  An information search system of the present invention is an information search system for searching a database based on a keyword input from a terminal and outputting and displaying the search result on the terminal, including the input keyword Based on search means for searching a web page from the database, browser number calculation means for calculating the number of viewers in each searched web page, and the number of viewers calculated by the viewer number calculation means And an information ordering means for ordering the retrieved Web pages.

  According to this configuration, since each Web page is ranked based on the number of viewers in each searched Web page, for example, the popular Web pages where the viewers are gathered are determined in a high order. Therefore, it is possible to efficiently search useful information reflecting the fashion and provide it to the user.

  In the information search system of the present invention, it is preferable that the viewer number calculating means calculates the number of current viewers in each searched Web page. In this case, since each Web page is ranked based on the current number of viewers in each searched Web page, for example, the popular Web pages where the viewers are currently gathering are arranged in a high order. Therefore, useful information reflecting the current fashion can be efficiently searched and provided to the user.

  In the information search system of the present invention, the viewer number calculation means may calculate the number of past viewers in each searched Web page. In this case, each Web page is ranked based not only on the current number of viewers on each searched Web page but also on the number of past viewers. It is possible to determine the most popular Web pages that are gathered in a high order, so that it is possible to efficiently search and provide useful information that reflects the trend that has continued from the past to the present to the user. Become.

  For example, in the information search system of the present invention, the number-of-viewers calculating unit calculates the number of viewers in each Web page based on access history information for each searched Web page.

  The access history database 24 correlates to access history information on web pages in all mobile terminals 2 managed by the mobile communication center 6, for example, telephone number information of accessed mobile terminals 2, accessed date information, and web pages. Stored URL information and the like. The index database 25 stores various information such as documents to be searched based on keywords.

  In addition, the control unit 21 includes a browser number calculation unit (browser number calculation means) 30 that calculates the current number of viewers (the number of viewers) in the Web page included in the search result by the search unit 27. Yes. The browser number calculation unit 30 acquires the access history for the Web page included in the search result from the access history database 24, and calculates the number of viewers on the Web page. For example, the browser number calculation unit 30 accesses the web page and counts the number of viewers that have not transferred to another web page, thereby calculating the current number of viewers on the web page. In the browser number calculation unit 30, the number of viewers in each Web page can be accurately calculated by calculating the number of viewers in the Web page included in the search result based on the access history information. Yes.

  In addition, the control unit 21 includes an information ordering unit (information ordering unit) 32 that ranks Web pages included in the search results based on the number of viewers calculated by the number of viewers calculating unit 30. . The information ordering unit 32 ranks the Web pages included in the search results based on the number of viewers calculated by the viewer number calculating unit 30 and the number of keywords included in each Web page. More specifically, the Web page included in the search result is converted into points based on the number of viewers calculated by the number-of-viewers calculation unit 30 and the number of keywords included in each Web page. In response, each Web page included in the search result is ranked.

  The information ordering unit 32 determines the display order of the searched Web pages on the mobile terminal 2 based on the number of viewers calculated by the viewer number calculation unit 30 and the number of keywords included in each Web page. An order determination program (display order determination means) is included. Accordingly, it is possible to determine the display order of each searched Web page on the mobile terminal 2 based on the number of viewers and the number of keywords included in each Web page.

  In addition, the information ordering unit 32 rearranges the searched web pages in the order of the high number of points converted from the number of viewers and the number of keywords included in each web page, and displays the information on the mobile terminal 2. A replacement program (information rearranging means) is included. Thereby, based on the number of viewers and the number of keywords included in each Web page, it is possible to rearrange the Web pages searched in the order of the highest number of points and display them on the terminal.

  Next, a keyword search operation in the information search system 1 having the above configuration will be described with reference to FIG. FIG. 4 is a sequence diagram for explaining a keyword search operation in information search system 1 according to the present embodiment.

  As shown in FIG. 4, the user inputs a keyword related to information to be searched from the input unit 14 of his / her mobile terminal 2. The input keyword is transmitted from the communication control unit 12 to the mobile communication center 6 via the mobile communication network 4 (step (hereinafter referred to as “ST”) 1).

  The keyword from the portable terminal 2 is sent to the control unit 21 (or the search unit 26) via the communication control unit 22 of the mobile communication center 6. Upon receiving this, the search unit 26 searches the index database 25 for information including this keyword (ST2: search step). At this time, in the index database 25, a Web page including the keyword is extracted (ST3) and sent to the search unit 26. The search unit 26 obtains these Web pages as search results.

  When the Web page including the keyword is sent to the search unit 26, the control unit 21 inquires the access history database 24 about the access history information on the Web page (ST4). When this inquiry is received, the corresponding access history information is searched in the access history database 24 and answered to the control unit 21 (ST5).

  When the access history information is received, the control unit 21 (the number of viewers calculating unit 30) calculates the number of viewers on the Web page included in the search result (ST6: number of viewers calculating step). Specifically, the control unit 21 analyzes the access history information received from the access history database 24, and calculates the number of viewers on the Web page included in the search result.

  A method for calculating the number of viewers in the control unit 21 will be described with reference to specific examples shown in FIGS. FIG. 5 is a diagram illustrating an example of access history information for the Web pages A to C included in the search result. As shown in FIG. 5, the access history information includes access history number information 51 associated with each access history information, telephone number information 52 assigned to the portable terminal 2, access date / time information 53, URL information 54 of the Web page is included. The information included in the access history information may include other information.

  FIG. 5 shows access history information between “January 1, 2007 0: 0: 01” and “January 1, 2007 12:00:15”. For example, in the access history information shown in FIG. 5, the mobile terminal 2 with the phone number 090-0000-0002 accessed the web page C at 11:59:55 on January 1, 2007 (access history number 45). Then, it can be seen that the web page B is accessed again at 11:59:58 on the same day (access history number 49).

  When such access history information is received from the access history database 24, the control unit 21 analyzes the access history information and calculates the number of viewers as shown in FIG. FIG. 6 is a diagram showing the number of viewers calculated by the viewer number calculation unit 30 from the access history information shown in FIG. FIG. 6A shows the number of viewers calculated at 11:59:59 on January 1, 2007 shown in FIG. 5, and FIG. 6B shows the number of viewers on January 1, 2007 at 12:00. It is the number of viewers calculated at the time of 00 minutes 30 seconds.

  Note that the number-of-viewers calculation unit 30 calculates the number of viewers based on access history information within a certain period of time until a search instruction is received. Specifically, the access history information included in 30 seconds before the time when the search instruction is received is set as valid access history information, and the number of viewers is not counted based on the access history information before that time. Therefore, in FIG. 6A, access history numbers 45 to 50 are specified as valid access history information, and in FIG. 6B, access history numbers 51 to 55 are specified as valid access history information. The In this way, access history information more than a certain time before receiving the search instruction is excluded when calculating the number of viewers, so the number of viewers based on the latest access history information up to the time when the search instruction is received Can be calculated.

  As shown in FIG. 6 (a), at the time of 11:59:59 on January 1, 2007 shown in FIG. 5, the number of viewers on the Web page B is 4, and the viewers on the Web page C You can see that the number is one. Note that the access history information of the access history number 45 is counted as the number of viewers of the Web page C because the Web page B is accessed again at 11:59:58 on the same day as described above. Absent.

  Further, as shown in FIG. 6B, at the time of 11:00:30 on January 1, 2007 shown in FIG. 5, the number of viewers in the Web page A is two, and in the Web page C, It can be seen that the number of viewers is three. In this way, the control unit 21 calculates the number of viewers on the Web page included in the search result based on the access history information.

  When the number of viewers in the Web page included in the search result is calculated as described above, the control unit 21 (information ordering unit 32) displays the number of viewers in each Web page and the keyword included in each Web page. Based on the number, the searched Web pages are ranked (ST7: information ranking step). For example, the control unit 21 determines the display order of the searched Web pages on the mobile terminal 2 based on the number of viewers in each Web page and the number of keywords included in each Web page.

  A web page ordering method in the control unit 21 will be described with reference to FIGS. 5 and 6 and a specific example shown in FIG. In the following, when points are converted by the information ordering unit 32, 1 point is assigned to each keyword included in the searched Web page, while 1 point is assigned to each of the number of viewers on each Web page. Shall be calculated.

  FIG. 7 is a diagram illustrating an example of a Web page searched by the information search system 1 according to the present embodiment. Here, FIGS. 7A to 7C show examples of Web pages searched based on the keyword “game bulletin”, and FIG. 7D shows a Web where many visitors gather at a high rate. An example of a page is shown.

  FIGS. 7A and 7B correspond to Web page A shown in FIGS. 5 and 6 and are associated with URL “http: //a.html”. FIG. 7C corresponds to the Web page B shown in FIGS. 5 and 6 and is assumed to be associated with the URL “http: //b.html”. FIG. 7D corresponds to the Web page C shown in FIGS. 5 and 6 and is assumed to be associated with the URL “http: //c.html”.

  FIG. 7B shows the Web page A updated from FIG. In this case, it is assumed that FIG. 7B is updated from FIG. 7A at 12:00:00 on January 1, 2007 shown in FIG. On the other hand, it is assumed that FIG. 7C and FIG. 7D have not been updated before the period shown in FIG. In particular, the contents of the Web page B shown in FIG. 7C indicate the breaking news of the martial arts performed on the day before the period shown in FIG. 5, that is, on December 31, 2006.

  The web page A shown in FIG. 7A includes two keywords “game bulletin”, and the web page A shown in FIG. 7B includes one keyword “game bulletin”. It is. In this case, the former is a web page corresponding to a simple notification that does not include a game bulletin, and the latter is a web page that includes a game bulletin. In the Web page B shown in FIG. 7C, two keywords “game breaking news” are included. In the Web page C shown in FIG. 7D, the keyword “game breaking news” is not included.

  In such Web pages A to C, it is assumed that the access history information shown in FIG. 5 and the number of viewers shown in FIG. 6 are obtained. In this case, when the Web page ordering is performed by the information ordering unit 32 at 11:59:59 on January 1, 2007, the Web page A includes two keywords. Since the number of viewers is 0 as shown in 6 (a), it is calculated as 2 points in total. In addition, in Web page B, two keywords are included, and since the number of viewers is four as shown in FIG. 6A, the total is calculated as 6 points. In Web page C, although the number of viewers is one as shown in FIG. 6A, since no keyword is included, it is not included in the search result. Therefore, the information ordering unit 32 performs ordering in the order of the Web page B and the Web page A.

  On the other hand, when Web pages are ordered by the information ordering unit 32 at 12:00:30 on January 1, 2007, the Web page A includes one keyword, while FIG. Since the number of viewers is two as shown in b), the total is calculated as 3 points. On the other hand, the Web page B includes two keywords, and the number of viewers is 0 as shown in FIG. 6B, so that it is calculated as 2 points in total. In Web page C, although the number of viewers is three as shown in FIG. 6B, since no keyword is included, it is not included in the search results. Therefore, the information ordering unit 32 performs ordering in the order of the Web page A and the Web page B.

  Here, in the case where similar information is obtained, a case where Web pages are ordered in consideration of only the number of keywords included will be described as a reference example. At the time of 11:59:59 on January 1, 2007, as described above, Web page A and Web page B contain two keywords, so they are ranked based on the number of keywords included. It is difficult to perform, and ranking is performed based on prior settings and the like. Since Web page C does not include a keyword, it is the same that it is not included in the search result.

  As can be seen from this, according to the ordering method by the information ordering unit 32 according to the present embodiment, priority is given to a Web page having a large value as information by considering the current number of viewers in the Web page. Ordering is performed. For this reason, unlike the case where Web pages are ordered in consideration of only the number of keywords, Web page B having information as a game bulletin is higher than Web page A, which is a Web page corresponding to simple notifications. The ordering is done.

  On the other hand, at 12:00:30 on January 1, 2007, Web page A includes one keyword, while Web page B includes two keywords. The ordering is performed in the order of Web pages A. Since Web page C does not include a keyword, it is the same that it is not included in the search result.

  As can be seen from the above, according to the ordering method by the information ordering unit 32 according to the present embodiment, priority is given to Web pages including useful information by considering the number of viewers in the Web page. Is done. For this reason, unlike the case where Web pages are ranked in consideration only of the number of keywords included, Web page A having the latest game bulletin is ranked higher than Web page B having the game bulletin played yesterday. Is going on.

  When the Web pages included in the search results are ordered in this way, the ordered Web pages are transmitted from the communication control unit 22 to the mobile terminal 2 via the mobile communication network 4 (ST8). And it displays on the display part 13 of the portable terminal 2 in the ordered order (ST9). Thus, the web page searched based on the keyword input from the user is displayed on the mobile terminal 2.

  As described above, in the information search system 1 according to the first embodiment, not only the number of keywords included in the searched Web page but also the current number of viewers in the Web page is considered. Ordering is done. As a result, it is possible to determine the popular Web pages where the viewers are gathered in a high order, so that it is possible to efficiently search and provide useful information reflecting the current fashion to the user. .

(Embodiment 2)
In the information search system 1 according to the second embodiment, when the viewer number calculation unit 30 included in the control unit 21 of the mobile communication center 6 calculates the number of viewers on the Web page included in the search result, It is different from the information search system 1 according to the first embodiment that calculates only the current number of viewers in the Web page included in the search result in that the calculation is performed including the number.

  In the information search system 1 according to the second embodiment, in ST6 shown in FIG. 4, for example, the number of viewers on the Web page is calculated based on the past one week access history information. The number of viewers including not only the current number of viewers but also the number of past viewers is obtained by performing ordering by the information ordering unit 32 in the same manner as the information search system 1 according to the first embodiment. It is possible to rank Web pages searched based on the above. This makes it possible to determine the high order of popular Web pages that have been gathered stably from the past, so it is possible to efficiently search for useful information that reflects trends that have continued from the past to the present. Can be provided to users.

  In addition, when calculating the number of viewers on the Web page included in the search result including the number of past viewers in this way, when the information ordering unit 32 converts the number of viewers into points, It is preferable to change the number of points given according to the browsing timing. For example, it is possible to give 1 point per person for the current viewer, and 0.5 points per person for the past viewers. In particular, when changing the number of points given according to the browsing timing, it is preferable to increase the number of points given as the browsing timing is newer. In this case, it is possible to order Web pages that emphasize the number of viewers browsed at a newer timing.

(Embodiment 3)
In the information search system 1 according to the third embodiment, the information ordering unit 32 included in the control unit 21 of the mobile communication center 6 ranks the Web pages including the browsing time of the viewer with respect to the searched Web pages.
