A server that provides the communication unit that communicates with the client, an article recording unit that records an article posted from the client via the communication unit in the article DB, and a summary of the contents of the article stored in the article DB. Article content DB that stores an article content summary that represents the topic content DB that stores a topic content summary that represents a summary of the contents of a thread that is a set of articles among the articles stored in the article DB for each thread When a new article is recorded in the article DB by the article recording unit, the article content summary of the article is created and stored in the article content DB. In addition, a content summary unit that updates the content of the topic content DB for the thread related to the article using the created article content summary, and the topic content DB when the topic content DB is updated. The topic content summary is compared between the threads, and if there is a thread whose topic content summary is close between the threads, an article introducing the thread is generated, and the generated article is It includes at least a content comparison unit that records in the article DB as an article of a thread that is close to the topic content summary .

According to a third aspect of the present invention, an article posted from a client is recorded in an article DB, and a record for recording a program for constructing an electronic bulletin board system that provides the contents of an article recorded in the article DB as an electronic bulletin board A content summarization function for creating a topic content summary that represents a summary of the content of a thread that is a set of a series of articles, using the article recorded in the article DB on a server that provides the electronic bulletin board The topic content DB function for generating the topic content DB that records the topic content summary created by the content summary function and the topic content DB are referred to, and the topic content summaries are compared between the threads. , when the topic content summary between the thread there is a thread close generates an article to introduce the thread, the story of the article that the generated Recording a program for constructing an electronic bulletin board system, characterized in that allowed to produce the content comparison function content summary records in the article DB as a thread articles close.

According to a fourth aspect of the present invention, there is recorded a program for building an electronic bulletin board system that records articles posted from a client in an article DB and provides the contents of the articles recorded in the article DB as an electronic bulletin board. A server that provides the electronic bulletin board, a communication unit that communicates with the client, an article recording function that records an article posted from the client via the communication unit in the article DB, and an article DB An article content DB function for generating an article content DB for storing an article content summary representing a summary of the contents of the stored articles, and the content of a thread that is a set of articles among the articles stored in the article DB. A topic content DB function for generating a topic content DB that stores a topic content summary representing a summary for each thread, and the article DB by the article recording function. When a new article is recorded, the article content summary of the article is created and stored in the article content DB, and the topic related to the thread related to the article is created using the created article content summary. A content summarization function for updating the content of the content DB, and when the topic content DB is updated, the topic content DB is referred to, the topic content summaries are compared among the threads, and the topic is compared between the threads. If there is a thread with a similar content summary, generate an article that introduces the thread, and generate a content comparison function that records the generated article in the article DB as an article of a thread with a similar topic content summary A program for building an electronic bulletin board system characterized by the above is recorded.

  According to the present invention, by comparing a plurality of articles and a plurality of user profiles, respectively, it is possible to provide an electronic bulletin board system that makes the search accuracy of articles that the user is interested in more accurate and automatically notifies. it can.

  Next, the electronic bulletin board system of the present invention configured as described above will be described in more detail with reference to the drawings.

  (Embodiment in the First Invention) FIG. 1 is a block diagram showing an embodiment of the configuration of the electronic bulletin board system in the first invention of the present invention.

  Referring to FIG. 1, the first invention of the present invention comprises one server 1 and a plurality of clients 2.

  The server 1 may be configured by a recording medium 3 on which an electronic bulletin board server program is recorded.

  The client 2 may be configured by the recording medium 4 on which the electronic bulletin board client program is recorded. In addition, the client 2 may be in any form that can refer to the content of the article on the electronic bulletin board recorded in the server 1 or the like or can post the article, and is not particularly defined in the present invention. In addition, a program that allows the contents of the electronic bulletin board to be referenced and posted from the server 1 or another server is received. For example, if the electronic bulletin board is constructed on the WWW (World Wide Web), this recording medium is a browser program capable of browsing the WWW. The client program of the electronic bulletin board system may be recorded on the recording medium 4 or only partially recorded and may be received from a server or the like as necessary.

  The server 1 has a communication unit 5 that communicates with the client 2, an article recording unit 6 that records an article transmitted from the client 2 in the article DB 7, and a content for each thread based on the article recorded in the article DB 7. The content summary section 8 to be summarized, the article content DB 9 for recording the article content summarized by the content summary section, the topic content DB 10 for recording the summary of the topic content summarized by the content summary section, and the article content DB A content comparison unit 11 that compares the content of each thread is included.

  Here, the present invention will be described in detail with specific operation examples. Assume that an article provided from the server 1 is displayed as shown in FIG. 2 in the client 2 used by the user E. In the example of FIG. 2, in response to the article “It seems that the new video card scheduled to be released from X company seems to be fast”, “There was an evaluation article in a magazine called Y.” There are two articles that are followed, and it is a branching display.

  Then, a case where user E has posted a follow-up article “The price seems to be cheap according to that article” in response to an article “An evaluation article was published in a magazine called Y” will be described. The articles displayed on each client are part of the articles recorded on the server 1, and the server 1 records some or all of the articles posted so far in the article DB 7. And For example, the server 1 may set a period for storing articles, and articles that have expired may be deleted. In addition to the article content, for example, information such as the article poster and the article to be followed is added to the article received by the server 1. In addition to these, information such as the posting date and the title of the article may be added. Since these functions are functions realized in the prior art, detailed description will not be given. Further, the article DB 7 records the article content and the added information together with the article ID assigned to each received article.

  Here, for the sake of explanation, the article DB 7 records items such as the article ID, the name of the user who posted the article, the article to be followed, and the article content in a table format as shown in FIG. To do. In FIG. 3, the articles shown in FIG. 2 are recorded as article IDs 100, 101, and 102. In addition, for example, an article with article ID 10 is recorded.

  If user E posts a follow-up article with the article ID 101, “Your evaluation article was in a magazine called Y”, “The price seems to be cheaper according to that article.” E inputs an article from the client 2 and transmits it to the server 1, and the server 1 receives the article transmitted from the client 2 in the communication unit 5 (502). The article received by the communication unit 5 is transferred to the article recording unit 6 (506).

  The received article is assigned an article ID in the article recording unit 6, and is recorded in the article DB 7 together with information such as the user name, follow-up ID, and article content (607). In this example, when the article DB 7 is in the state as shown in FIG. 3, if the user E posts an article “The price seems to be cheap according to that article”, the article recording unit 6 displays the article DB 7 in FIG. 4. It is updated as follows.

  When the received article is recorded in the article DB 7 (607), the article recording unit 6 passes the recorded content to the communication unit 5 (605), and transmits it to all clients connected to the server 1 (such as 205). Update the display state of. However, instead of a method of sending a newly posted article from the server 1 to the client, a method of sending back the content recorded in the article DB 7 only when a newly registered article is requested from the client may be used. However, the present invention is not limited to this form.

  The article recording unit 6 records the received article in the article DB 7 (607) and simultaneously transmits the article ID of the received article to the content summary unit 8 (608). The content summary unit 8 retrieves the received article from the article DB 7 (807), and records the summary of the article content in the article content DB 9 (809).

  The summary of the article content is expressed, for example, by a set of several keywords. As a means for generating a summary from the content of an article, for example, a method of extracting a keyword by performing morphological analysis can be used as disclosed in JP-A-8-221440.

  For example, a description will be given assuming that the content summary unit 8 extracts nouns as keywords from the article as a summary of the article content. When the article DB 7 is as shown in FIG. 3, the article content DB 9 records the article ID and the extracted keyword for each article in a table format as shown in FIG.

  When the article recording unit 6 informs the content summary unit 8 that a new article with the article ID 103 has been recorded in the article DB 7 (608), the content summary unit 8 searches the article DB 7 for the article content with the article ID 103. Then, the noun is extracted as a keyword and the article content DB 9 is updated as shown in FIG. 6 (809).

  When the summary of the received article is recorded in the article content DB 9 (809), the content summary unit 8 searches the article DB 7 for a thread having the article as a terminal (807). Here, the article at the end refers to the article that is not followed, the thread that ends at an article is the article that the article at the end follows, and the article that the article follows It refers to a series of articles that date back.

  For example, the article with the article ID 103 newly added to the article DB 7 is the last article, and the article that has followed the follow-up destination of this article, that is, the article that is the follow-up article with the article ID 103 in the example of FIG. An ID 101 and an article ID 100 that is a follow-up article of the article ID 101 are threads that end at the article ID 103.

  When the content summarizing section 8 searches for a thread that ends with an article added to the article DB 7 (807), it searches the article content DB 9 for the keyword of the article included in the thread (809) and represents the contents of the thread. The topic content DB 10 is updated as a keyword (8010).

  For example, as shown in FIG. 7, the topic content DB 10 records the article IDs at the tips and ends of threads and keywords representing the contents of the threads in a table format. The keyword representing the content of the thread is determined by taking the logical sum of the keywords of the articles included in the thread.

  As a means for determining a keyword representing the content of a thread from keywords of articles included in the thread, in addition to a method of taking a logical sum, keywords included in articles that are older than a certain degree (for example, articles that have been followed more than 10 times) There are a method of ignoring, a method of determining the total number of keywords representing the contents of the thread, and prioritizing a keyword included in a new article or a keyword appearing multiple times.

  Here, a case will be described in which the article ID 103 is added to the article DB 7 when the topic content DB 10 is recorded as shown in FIG. The content summary unit 8 records the article with the article ID 103 in the article content DB 9 (908), and searches the article DB 7 for a thread having the article with the article ID 103 as a terminal (807). Articles having article IDs 100, 101, and 103 are searched as threads to be obtained.

  When the article ID 103 is examined in the article DB 7 (807), it is a follow article with the article ID 101. Therefore, the content summary unit 8 updates the portion where the end article ID of the thread of the topic content DB 10 is recorded as 103. (8010). Also, the keyword included in the articles with article IDs 100, 101, and 103 is searched from the article content DB 9 (809), and ORed and updated as a keyword representing the content of the thread whose end article ID is 103 in the topic content DB 10. (8010). When the article with the article ID 103 is added in this way, the topic content DB 10 is updated from the state shown in FIG. 7 to the state shown in FIG.

  When the topic content DB 10 is updated, the content comparison unit 11 compares a keyword representing the topic content of the updated thread with a keyword having a different article ID at the tip in another thread, and searches for a similar one. . The determination of whether the contents are close is, for example, when there are several or more (for example, two or more) common keywords included in both, or when the total number of keywords representing the thread contents is determined Can be based on a case where a certain percentage of keywords is included (for example, 10% or more). Further, even if the keywords are not exactly the same, it is possible to use a means for determining that the keywords are the same using a synonym dictionary or a thesaurus dictionary.

  Whether or not the contents in the present embodiment are similar will be described as being determined based on whether or not there are two or more common keywords included in both.

  When the topic content DB 10 is updated (8010), the content comparison unit 11 searches for keywords representing the updated thread content from the topic content DB 10 (11010). When the article ID 103 is recorded in the article DB 7 and the article content DB 9 and the topic content DB 10 are updated, the keyword “X company, sale schedule, video card, "Y, magazine, evaluation article" is searched.

  Since the thread whose end article ID is 103 has the article ID at the tip of the thread as 100, the content comparison unit 11 is a thread whose tip article ID is not 100, and “X company, planned to be released, video card, A thread including two or more keywords such as “Y, magazine, evaluation article” is searched from the topic content DB 10 (11010). As a thread that satisfies the condition, a thread having an article ID of 10 at the end of the thread is searched, and the content comparison unit 11 is a thread having a content close to the thread having the article ID of 103 and the thread having the article ID of 10 at the end. It is judged that.

  In this example, a case is described in which only one thread is searched as a thread whose content is close, but the following description is the same when a plurality of threads are searched.

  When a thread with similar content is searched, the content comparison unit 11 posts an article introducing each other to each thread. However, if an article introducing each other has already been posted, it will not be posted again. For example, it may be possible to post again only when there is a certain interval, such as when a thread that posts articles introducing each other has 10 or more followers.

  For example, the posting user name is “System”, the article content is “following the article with article ID 10”, and there is an article such as “There is an article with content such as a video card and price in a thread including an article with ID 103”, and the article ID 103. As an article follow-up, an article such as “There is an article with contents such as a video card and a price in a thread containing an article with ID 10” is generated and passed to the communication unit 5 (1105).

  The communication unit 5 handles the article generated by the content comparison unit 11 in the same manner as the article transmitted from the client. That is, it is passed to the article recording unit 6 (506), recorded in the article DB 7 (607), the recorded content is returned to the communication unit (605), and transmitted to all clients connected to the server 1 (502) Update the client's display state.

  However, the article generated by the content comparison unit 11 is registered as having no keyword representing the article content when recorded in the article content DB 9 (809).

  Therefore, an article such as “There is an article with a content such as a video card and price in a thread containing an article with ID 103” and an article content “following the article with article ID 103 is a video card in a thread containing an article with ID 10”. When an article such as “There is an article with a price” is generated by the contents comparison unit 11, the article DB 7 is updated as shown in FIG. 9 (607), and the article contents DB 9 is updated as shown in FIG. 10 (809). ). As the article content DB 9 is updated, the content summary unit 8 updates the article ID at the end of the thread in the topic content DB 10 as shown in FIG. 11 (8010).

  In this way, it is not just a comparison of articles, but the relation of threads is judged from the contents of multiple articles that are in a follow relationship, and related threads for multiple users who are reading different threads Can be notified.

  (Second Embodiment) Next, a second embodiment of the present invention will be described.

  In the electronic bulletin board system according to the embodiment of the second invention, as shown in FIG. 12, a user model 13 expressing the user's interest in addition to the components of the electronic bulletin board system according to the embodiment of the first invention. A user model update unit 12 that updates the user model 13 using the content recorded in the user model 13 and the content of an article posted by the user, a user relationship DB 14 that manages whether the users know each other, and a user And a user model comparison unit 15 for comparing contents recorded in the model 13.

  The user model 13 is created by the user model updating unit 12 and manages, for example, as shown in FIG. 13, a user name and a keyword representing the posted article content of the user in a tabular format. The keyword representing the content of the posted article of the user is determined by taking the logical sum of all the keywords included in the articles that the user has posted so far. The user model 13 can also employ a method that allows each user to register keywords of interest to the user.

  The user model update unit 12 determines a keyword representing the content of the posted article of the user. In addition to the method of calculating the logical sum of all the keywords included in the articles that the user has posted so far, for example, the method of calculating the logical sum of the keywords included in only the latest 10 articles posted by the user, There is a method of determining the total number of keywords to be recorded, and deleting old keywords every time a new keyword is added.

  For example, as shown in FIG. 14, the user relationship DB 14 manages whether or not each user knows each other in a table format. Assume that users who have posted articles in the same thread know each other, and FIG. 14 shows that user B and user C, user B and user D, and user C and user D know each other. ing.

  Here, the user model 13 is recorded as shown in FIG. 13, the article DB 7 is recorded as shown in FIG. 3, the article content DB 9 is recorded as shown in FIG. 5, and the topic content DB 10 is recorded as shown in FIG. The operation of the embodiment of the second invention will be described for the case where an article with ID 103 is posted.

  In the electronic bulletin board system according to the second embodiment, the operations described below are added in addition to the operations described in the first embodiment.

  The article with the article ID 103 received by the communication unit 5 is transferred to the article recording unit 6, and the article DB 7, the article content DB 9, and the topic content DB 10 are respectively shown in FIG. It is updated as shown in FIGS.

  In the embodiment of the second invention, it is further notified that the article ID of the article newly posted from the article recording unit 6 to the user model updating unit 12 is 103 (6012).

  The user model update unit 12 checks whether the user E is recorded in the user model 13 (12013). If it has already been recorded, the keyword included in the article posted from the article content DB 9 is checked (1209), and logically added with the already registered posted content keyword and updated (12013). If not recorded, the user E is newly registered (12013), the keyword included in the article posted from the article content DB 9 is examined (1209), and newly registered as the posted content keyword (12013). The user model 13 is updated as shown in FIG. 15 from the state of FIG.

  Further, the article recording unit 6 searches the article DB 7 that the users who have posted to the thread including the article with the article ID 103 posted by the user E are B, C, and D (607), and the user E is stored in the user relation DB 14 with the user E. (15014) and updated as shown in FIG.

  When the user model 13 is updated, the user model comparison unit 15 searches the post content keyword of the user E updated from the user model 13 (15013) and compares it with the post content keyword of another user.

  Judgment of whether or not the posted content is similar is, for example, when there are several or more (for example, two or more) common keywords included in either, or by determining the total number of posted content keywords, It can be based on the case where a certain percentage or more (for example, 10% or more) is included. Further, even if the keywords are not exactly the same, it is possible to use a means for determining that the keywords are the same using a synonym dictionary or a thesaurus dictionary.

  Whether or not the posted contents in this example are close will be described based on whether or not there are two or more common keywords included in both.

  When the user model 13 is updated as shown in FIG. 15, the user model comparison unit 15 determines that the user A is close to the content posted by the user E because the keywords “article, price” are common. In this example, a case where only one person is searched for as a user whose posting content is close is described. However, the following description is the same when a plurality of users are searched.

  When a user whose posting content is close is searched, the user model comparison unit 15 searches the user relationship DB 14 (15014), and searches for users who are close to the posting content and do not know each other. When the user relationship DB 14 is as shown in FIG. 16, the user A and the user E are regarded as not knowing each other. Therefore, in the user model comparison unit 15, the user A and the user E are close to each other. Discovered as users who do not know each other.

  Next, the user model comparison unit 15 transmits a message for introducing each other to the clients of the user A and the user E via the communication unit 5 (1505) (502 and the like). Since the information is not valuable to users other than A and E, it is not posted as an article, but is transmitted as a message using means that can be viewed only by a specific user. As means for sending a message, e-mail or the like can be used, for example.

  In this example, for user A, “A person named E makes a posting that includes keywords such as articles and prices.” The message “posting including a keyword such as” is transmitted to the client of user A and user E.

  Users who are close to each other and who do not know each other get to know each other and exchange information, so that articles that only one of them knows can be taught. In addition, since the user model is automatically updated by the posted article, the user does not need to update the user model himself / herself, and the burden on the user can be reduced.

  (Third Embodiment) Next, a third embodiment of the present invention will be described.

  In the electronic bulletin board system according to the embodiment of the third invention, as shown in FIG. 18, each thread recorded in the topic content DB 10 in addition to the components of the electronic bulletin board system according to the embodiment of the second invention. And a topic UM comparison unit 16 that compares a keyword representing the content of the posting for each user recorded in the user model 13.

  The operation of the embodiment of the third invention will be described by taking as an example the case where the article having the article ID 103 described above is received.

  In the electronic bulletin board system according to the third embodiment, the following operations are added in addition to the operations described in the first and second embodiments.

  Assume that the topic content DB 10 is updated as shown in FIG. 11 and the user model 13 is updated as shown in FIG. 15 by receiving the article with the article ID 103. The topic UM comparison unit 16 compares the keyword representing the content for each thread recorded in the topic content DB 10 with the keyword representing the posted content for each user recorded in the user model 13 (16010, 16013). It is determined whether the topic content is similar to the content posted by the user.

  Judgment whether the topic content and the posted content of the user are similar, for example, when there are several or more (for example, two or more) common keywords included in both, recorded in the topic content keyword and the posted content keyword It is possible to determine the total number of keywords to be determined and use a case in which more than a certain proportion of keywords (for example, 10% or more) is included. Further, even if the keywords are not exactly the same, it is possible to use a means for determining that the keywords are the same using a synonym dictionary or a thesaurus dictionary.

  In the following description, it is assumed that whether the topic content and the posted content are close is determined based on whether there are two or more common keywords included in both.

  When the topic content DB 10 is as shown in FIG. 11 and the user model 13 is as shown in FIG. 15, the topic UM comparison unit 16 determines the posting content keyword of the user A in FIG. 15 and the thread end in FIG. Since the keywords such as “video card, price” are common among the content keywords with the article ID 105, it is determined that the posted content of the user A is close to the topic content of the thread whose end article ID is 105. In addition, the topic content of the thread whose user B's post content and the end article ID are 105, the topic content of the thread whose user B's post content and the end article ID are 102, and the content of the user C's post It is determined that the topic content of the thread whose end article ID is 105, the posted content of the user E and the topic content of the thread whose end article ID is 105 are close.

  With respect to a thread and a user who are determined to be close to the topic content and the posted content, it is checked from the article DB 7 whether or not the user has posted an article to the thread (1607). If the message has not been posted, the topic UM comparison unit 16 sends a message introducing the thread to the user's client via the communication unit 5 (1605) (502, etc.). In this example, for the article ID 105 at the end of the thread, since the user A has not posted an article to the thread, a message introducing the thread having the article ID 105 at the end of the thread is transmitted to the user A. . For threads and users that are judged to be close to other topic content and posted content, the thread is introduced because it can be understood that the user has posted to the thread by examining the article DB 7 (1607). Do not send messages.

  Further, the topic UM comparison unit 16 records which thread is introduced to which user so that the same thread is not introduced to the same user. Since the information is not valuable to other users other than the user, the information is not posted as an article, and is transmitted as a message using a means that only the user can see. As means for sending a message, e-mail or the like can be used, for example.

  In this example, a case where only one set of users and threads is searched is described, but the following description is the same when a plurality of sets of users and threads are searched.

  The topic UM comparison unit 16 sends a message to the user A, for example, “A thread that includes an article whose article ID is 105 includes a keyword such as a video card and a price”. 5 (1605) and transmit (502, etc.).

  In this way, the user can automatically notify the server of a topic that he / she may be interested in according to the posted content simply by posting the article.
