  And since this summary search index is provided to users as search results based on search terms in the same way as conventional Web search results, users can participate in each other's information search, and the user's knowledge and search objectives can be obtained through the search. It is possible to provide a new information search service that can share answers with each other.

  Further, from another viewpoint, the conventional information search service provides a user with a plurality of Web search results for a search word, and each Web search result has a one-to-one relationship with the search word. Yes, each search result is presented individually for the search term. On the other hand, the information search system 1 of the present embodiment holds a summary search index to which a user can add information and its information group, and the summary search index is presented as a search result for a search term. For this reason, the search term and the information group of the summary search index have a one-to-many relationship, and the information group edited by the user with respect to the search term is presented as the summary search index. Therefore, it is possible to output the information group in which the knowledge of the user and the answer to the search purpose are shared as a search result, and provide a new information discovery opportunity as compared with the conventional information search service. In addition, the information collection work burden on the user is reduced.

  In addition, when information is added to the summary search index, when the added information is from the Web search result, the search term input by the user in the search window to obtain this information is analyzed, and the analyzed search term Are automatically stored in the summary search storage unit 230 as keywords (summary keywords) representing the summary search index.

  Therefore, even if the user does not directly input a tag or the like to the summary search index, from the information added to the summary search index, in other words, by the Web information search and information addition action of each user participating in the summary, It is possible to automatically generate a representative keyword representing a collective search index. Moreover, since it is based on the information added to the subject of a summary search index, the representative keyword which reflected the user's interest naturally can be produced | generated.

(Second Embodiment)
13 to 18 are diagrams illustrating an example of an information search service system according to the second embodiment of the present invention.

  The present embodiment automatically extracts a summary search index related to the user and provides it to the user terminal 500 with respect to the first embodiment described above.

  As illustrated in FIG. 13, the search App server 200 includes a first keyword extraction unit 240 that extracts a main word as a summary topic keyword from a summary topic (summary title) stored in the summary search index table 231, and a first keyword extraction. A second keyword extraction unit 250 that extracts words appearing in information on the WWW together with the summary topic keyword extracted by the unit 240 as a related frequent word, and a keyword storage unit 260 that stores the summary topic keyword and the related frequent word Prepare.

  Further, a history information collecting unit 270 that collects the summary search index (summary page) browsed by the user and the number of times of browsing thereof, and collects the number of times the user participated in the summary search index and the number of times information is added to the summary search index. And a history information storage unit 280 for storing these user action histories.

  FIG. 14A is a diagram illustrating an example of the summary topic keyword table 261 in the keyword storage unit 260. For each summary ID, a summary topic, a summary topic keyword, and an identification ID (keyword ID) assigned to the summary topic keyword are stored. FIG. 14B is a diagram illustrating an example of the related frequent word table 262 in the keyword storage unit 260, and stores related frequent words for each keyword ID in the summary topic keyword table 261.

  FIG. 14C is a diagram showing an example of the summary participation history table (first history storage means) 235 of the summary search storage unit 230. The summary search index ID and the summary search index that participated for each user are shown in FIG. Stores the number of times information is added (participated).

  The first keyword extraction unit 240 extracts main words from the summary title of the summary search index according to a predetermined algorithm. For example, the subject is divided into words by morphological analysis, main words are extracted from the topic by referring to a glossary prepared in advance, and stored in the summary topic keyword table 261 of the keyword storage unit 260.

  Further, the second keyword extraction unit 250 uses the summary topic keywords stored in the summary topic keyword table 261, for example, refers to the WWW search storage unit 330 of the search index server 300 and collects it from a website on the Internet. In a news article or the like, related frequent words that frequently appear together with the summary topic keyword are extracted. The extracted related frequent words are stored in the related frequent word table 262 of the keyword storage unit 260.

  The processes of the first and second keyword extraction units 240 and 250 can be performed at an arbitrary timing. For example, when a new summary search index is created, the first keyword extraction unit 240 performs a summary topic keyword extraction process. May be performed. The second keyword extraction unit 250 also performs related frequent word extraction processing when a new summary topic keyword is stored in the summary topic keyword table 261 or in conjunction with the processing of the first keyword extraction unit 240. It may be.

  The history information collection unit 270 collects user action histories of users who use the information search service through the Web server 100 and stores them in the history information storage unit 280. In particular, in the present embodiment, the number of browsing of the summary search index (summary page) browsed by the user, and the number of times information is added to the summary search index that the user participated and the information group of the summary search index are collected.

  FIG. 15 is a diagram illustrating an example of the history information storage unit 280. A summary browsing history table (second history storage means) 281 adds a summary search index (summary search index ID) browsed for each user and information ( Stores the number of participations.

  FIG. 16 is an example of the processing flow of the first related summary extraction processing of this embodiment using summary topic keywords and related frequent words. For example, the first related summary extraction process is performed in conjunction with the second search process in step S19 of FIG. 4 in the first embodiment described above.

  As shown in FIG. 16, when the second search unit 210B receives a user's summary search index selection instruction (summary page request) via the Web server 100 (S101), the second search unit 210B is selected from the summary search storage unit 230. The information group of the summary search index is searched (S102), and the summary search index control unit 220 performs a first related summary extraction process using summary topic keywords and related frequent words.

  The summary search index control unit 220 refers to the summary topic keyword table 261 using the selected summary search index, and extracts the subject keyword and keyword ID of the corresponding summary search index ID (S103). Furthermore, the related frequent word table 262 is referred to, and the related frequent word corresponding to the extracted keyword ID is extracted (S104). The summary search index control unit 220 delivers the extracted summary topic keyword and related frequent words to the second search unit 210B.

  Then, the second search unit 210B searches the summary search storage unit 230 based on the extracted summary topic keyword and related frequent words, and is a corresponding summary search index, and the logged-in user does not participate. A summary search index is extracted (S105). At this time, it is also possible to search the related summary search index centered on the summary topic keyword by placing a weight on the summary topic keyword among the summary topic keyword and the related frequent word.

  Then, the search processing unit 210 transmits the information group of the selected summary search index together with the extracted related summary search index to the Web server 100. FIG. 18 is an example of a summary page on which the information group of the summary search index corresponding to FIG. 7 is displayed. The summary page on which the related summary list is displayed is transmitted to the user terminal 500 and the related summary search is displayed in the display column 2005 The index is displayed.

  FIG. 17 is an example of the processing flow of the second related summary extraction process of this embodiment using browsing history information as another form of the related summary extraction process.

  As illustrated in FIG. 17, when the second search unit 210B receives a user's summary search index selection instruction (summary page request) via the Web server 100 (S201), the second search unit 210B is selected from the summary search storage unit 230. The information group of the summary search index is searched (S202), and the summary search index control unit 220 performs a second related summary extraction process using the browsing history information.

  In the second related summary extraction process of the present embodiment, the related summary extraction process using the user-specific summary search index browsing history information collected by the history information collection unit 270 and stored in the history information storage unit 280 shown in FIG. Then, two extraction processes of the related summary extraction process using the summary participation history information stored in the summary search storage unit 230 shown in FIG. 14C can be performed.

  Steps S203 to S205 in FIG. 17 are related summary extraction processing using summary search index browsing history information for each user. The summary search index control unit 220 refers to the summary browsing history table 281 and selects the selected summary. Extract other users who browsed the search index. For example, referring to the example of FIG. 15, when the user U0001 selects the summary M006, the summary search index control unit 220 extracts another user U0002 who viewed the summary M006 (S203).

  Then, the browsing history of the extracted other users is referred to, and one or a plurality of summaries are extracted in order of the number of browsing times that the user is not browsing (S204). In the example of FIG. 15, the summary M003 and M010 other than the summary M006 are extracted as the browsing history of the other user U0002, and the summary search index that is not browsed by the user is M010, so M010 is extracted. The The summary search index control unit 220 passes the extracted summary ID (M010) to the second search unit 210B.

  Using the extracted summary ID, the second search unit 210B refers to the summary search storage unit 230 and searches for the corresponding summary search index (extracts the related summary search index) (S205).

  Steps S206 to S208 in FIG. 17 are related summary extraction processing using summary search index participation history information for each user, and the summary search index control unit 220 refers to the summary participation history table 235 and selects the selected summary. Extract other users who participated in the search index. For example, referring to the example of FIG. 14C, when the user U0001 selects the summary M006, the summary search index control unit 220 extracts another user U0002 who participated in the summary M006 (S206).

  Then, referring to the extracted summary participation history of other users, one or a plurality of summaries are extracted in descending order of the number of times that the user has not participated and the other user has participated (S207). In the example of FIG. 14C, summaries M002 and M013 other than summary M006 are extracted as summary participation histories of other users U0002. Therefore, these M002 and M013 are extracted. The summary search index control unit 220 passes the extracted summary ID (M002, M013) to the second search unit 210B.

  The second search unit 210B uses the extracted summary ID to search the corresponding summary search index with reference to the summary search storage unit 230 (extract related summary search index) (S208).

  Then, the summary search index control unit 220 transmits the information group of the summary search index selected together with the extracted related summary search index to the Web server 100, and the summary page on which the related summary list as shown in FIG. 18 is displayed. Is displayed on the user terminal 500.

  In the above-described related summary extraction process, one or more summary search indexes are extracted as related summary indexes in the descending order of the number of times that the user has not participated and other users have browsed or participated. At this time, a predetermined weighting process may be performed, or the number of related summary search indexes to be extracted may be limited. For example, a category that the user is good at or a category of interest may be stored in advance as user information, and a related summary related to the user's interest may be preferentially extracted.

  In the second related summary extraction process, a summary search index related to the user is extracted by two processes, a related summary extraction process using summary browsing history information and a summary relation extraction process using summary participation history information. However, the second related summary extraction process may be performed by either one of the related summary extraction processes.

  As described above, the related summary extraction process of the present embodiment can provide a summary search index that is automatically related to the user and that is not browsed / participated by the provided user. For this reason, the opportunity that users can participate in mutual information search increases, and the knowledge which the user has and the answer with respect to the search purpose can be shared further through search.

  As described above, the present invention has been described by taking a preferred embodiment as an example. However, the above-described processing for adding information to the summary search index can also be realized through a toolbar of a Web browser, for example, a Web page or image being browsed If you want to add to the search index, you can add information by selecting "Add Summary" from the toolbar.

  In addition, the process of adding information to the summary search index does not need to immediately add the result of the web search to the summary search index. For example, the link information and image information searched by the user in the storage area allocated for each user. Once saved and searched for various summary search indexes (summary pages), link information and image information stored in the user's save area may be added. Alternatively, the user search history may be stored by date and time, and information may be added from the user search history to a desired summary search index.

  In addition to the above-described hardware configuration, each server described above includes a CPU that controls the entire server, memory, mouse, keyboard, touch panel, scanner and other operation input means, printer and speaker output means, auxiliary storage, and the like. A device (such as a hard disk) can be provided.
