Description

  The present invention relates to a knowledge storage support system and a knowledge storage support program for notifying a user of a community or message that is of interest to the user.

  In recent years, systems have been developed in which users share knowledge with each other by exchanging messages, for example, on a virtual community created by the users.

  In such a system, it is necessary to prepare a place for many users to actively exchange opinions with the community, and to have a mechanism for voluntarily participating the user in the place for exchanging opinions. In this case, for example, it is conceivable that participation of a large number of users cannot be expected unless the existence of the community itself is known.

  Therefore, a knowledge accumulation support system that can easily promote voluntary participation of users in a virtual community that is a place for exchanging opinions has been disclosed (for example, see Patent Document 1).

  According to this knowledge accumulation support system, in order to promote participation in the community, a user designated by the community administrator is provisionally registered as a user who should participate as a participant in the community, and each of the temporary registrant clients. Regularly deliver solicitation emails to terminals.

When using this knowledge storage support system, the general flow of communication is:
(1) Create a community about a topic by a certain user (2) Invite people who want to participate in the user who created the community (3) Communicate using the community with the user who created the community and the invited user Will be done. As a result, knowledge such as individual know-how can be automatically and efficiently collected and accumulated using a virtual community.
JP 2002-342232 A

  However, in the above knowledge accumulation support system, the invited users are often limited users in the real community. For this reason, the advantage of the virtual community on the network which is a wider world is not utilized. For example, in a virtual community such as a communication system, it is expected that more useful knowledge and know-how are accumulated by participation of users other than the real community.

  In addition, as a user who uses the community, it is possible to expand the range of communication by participating not only in the solicited community but also in a community related to or interested in the community. Therefore, in the knowledge storage support system as described above, it is possible to search for related communities by searching for related information.

  However, it is difficult to check in real time the contents (messages) exchanged in a community that has not been newly created or joined.

  An object of the present invention is to provide a knowledge accumulation support system capable of notifying the contents of a user when a community that is interesting to the user is created or a message is posted.

  According to one aspect of the present invention, a community information storage that stores community information indicating a community including a community introduction sentence that is a character string for introducing a community created by a plurality of users to other users. Provided is a knowledge accumulation support system comprising: means and message information storage means for storing message information indicating a message including a character string posted to a community indicated by the community information stored in the community information storage means Is done. The knowledge storage support system includes a user information storage unit that stores user interest information indicating a keyword of interest to each of the plurality of users in association with each user, and an input for inputting the community information or the message information. Means, an extraction means for extracting a keyword from a character string included in a message indicated by community introduction text or message information indicated by community information input by the input means, and a keyword extracted by the extraction means Is stored in the user information storage unit when the determination unit determines that the keyword matches the keyword indicated by the user interest information stored in the user information storage unit. Has been Based on the user interest information, a specifying means for specifying a user associated with the keyword, and a message indicated by the community or message information indicated by the community information input by the input means are displayed by the specifying means. Notification means for notifying the specified user.

  According to the present invention, when a community that is interesting to a user is created or a message is posted, it is possible to notify the user of the content.

At this time, the extraction unit 571 executes processing for storing the extracted keyword in association with the community information indicating the community including the community introduction sentence from which the keyword is extracted or the message information indicating the message.

  The determination unit 572 notifies the community or the message based on the keyword indicated by the user interest information stored in the user information storage unit 421 and the keyword stored in the community information storage unit 422 or the message information storage unit 423. It is determined whether or not. The determination unit 572 performs the determination process according to the community information input by the community processing unit 54 or the non-member distribution information added to the message information input by the message operation unit 55. In addition, the determination unit 572 specifies a user who notifies a community or a message.

  FIG. 3 is a diagram illustrating an example of the data structure of the reference information stored in the user information storage unit 421. In the reference information, a user ID for identifying a user and a reference message ID indicating a message referred to by the user indicated by the user ID are associated with each other. Here, the reference message ID is a message ID that identifies the message indicated by the message information stored in the message information storage unit 423.

  In the example illustrated in FIG. 3, the user ID “A” and the reference message ID “1” are shown in association with each other. Similarly, a user ID “B”, a reference message ID “2”, a user ID “C”, and a reference message ID “3” are shown in association with each other.

  FIG. 4 is a diagram illustrating an example of a data structure of user interest information stored in the user information storage unit 421. In the user interest information, a user ID and a keyword of interest to the user indicated by the user ID are associated with each other. This keyword is extracted by the extraction unit 571 of the recommended information distribution determination unit 57 described above.

  In the example illustrated in FIG. 4, the user ID “A” and the keyword “Java (registered trademark)” are shown in association with each other. Similarly, a user ID “A”, a keyword “software”, a user ID “B”, and a keyword “trouble” are shown in association with each other.

  FIG. 5 is a diagram illustrating an example of the data structure of the community information storage unit 422. The community information storage unit 422 stores a community ID and a keyword extracted from the community introduction sentence of the community indicated by the community ID in association with each other.

  In addition, the keyword 1 to the keyword 6 shown in FIG.5 and FIG.6 mentioned above show the keyword (word) extracted from the community introduction sentence or the message.

  Next, a processing procedure for accumulating user interest information when the user inputs user information (including a user profile) using the client terminal 20 will be described with reference to the flowchart of FIG.

  First, the user information processing unit 53 inputs a user profile (including user information) including, for example, a character string input by the user (step S1). The user information processing unit 53 outputs the input user information to the recommended information distribution determination unit 57. At this time, the user information processing unit 53 stores the input user information in the user information storage unit 421.

  The extraction unit 571 of the recommendation information distribution determination unit 57 extracts a keyword from a character string included in the user profile included in the user information output from the user information processing unit 53 (step S2). For example, the extraction unit 571 extracts a character string having the appearance frequency equal to or higher than a certain value as a keyword according to the appearance frequency of the character string included in the user's profile.

  The extraction unit 571 stores (registers) user interest information indicating the keyword extracted in step S2 as a keyword that is of interest to the user in the user information storage unit 421 (step S3). Thereby, when user information containing a user's profile is inputted, user interest information can be accumulated according to the profile concerned.

  Next, a processing procedure for accumulating user interest information when, for example, the user refers to a message indicated by message information stored in the message information storage unit 423 will be described with reference to the flowchart of FIG.

  First, for example, when the user operates the client terminal 20 and refers to a message, the reference information processing unit 56 is notified of this (step S11).

  The reference information processing unit 56 stores reference information indicating that the user has referred to the message in the user information storage unit 421 (step S12). This reference information is information indicating the user ID and the message ID (reference message ID) of the referenced message.

  Next, the reference information processing unit 56 refers to the message information storage unit 423 and acquires the keyword of the message referenced by the user (step S13).

  Here, message information indicating the message referred to by the user is already stored in the message information storage unit 423. Further, as described above, the keyword extracted from the message indicated by the message information is stored in the message information storage unit 423 in association with the message information. That is, the reference information processing unit 56 acquires a keyword stored in the message information storage unit 423 in association with message information indicating a message referred to by the user.

  The reference information processing unit 56 stores (registers) user interest information indicating the keyword acquired in step S13 as a keyword that is of interest to the user in the user information storage unit 421 (step S14). Thereby, user interest information can be accumulated according to the message referred by the user like the case where user information including a user's profile is inputted.

  Next, a processing procedure for notifying the user of a new community when a new community is created will be described with reference to the flowchart of FIG.

  First, when a new community is created by the user operating the client terminal 20, the community processing unit 54 inputs community information (hereinafter referred to as new community information) indicating the new community via the Web server 62. (Step S21). The community processing unit 54 stores the input new community information in the community information storage unit 422 and outputs the new community information to the recommended information distribution determination unit 57.

  The extraction unit 571 of the recommended information distribution determination unit 57 performs a morphological analysis on the community introduction sentence of the new community indicated by the new community information output by the community processing unit 54, thereby generating a keyword from the character string included in the community introduction sentence. Is extracted (step S22). At this time, for example, the extraction unit 571 extracts all character strings (nouns) included in the community name of the community introduction sentence as keywords. In addition, the extraction unit 571 extracts, for example, a character string included in the introduction sentence of the community introduction sentence as a keyword whose appearance frequency is higher than a certain value.

  The extraction unit 571 stores (registers) the extracted keyword in the community information storage unit 422 (step S23).

  Next, the determination unit 572 of the recommended information distribution determination unit 57 determines that the new community indicated by the new community information stored in the community information storage unit 422 is a member (user) specified by the user who created the new community, for example. ) Is determined whether or not notification is possible (step S24). Note that the user can designate a member participating in a specific community, for example, by operating the client terminal 20.

  At this time, the determination unit 572 executes the determination process based on the above-described non-member distribution information added to the new community information. This non-member distribution information is information indicating whether or not to notify the community to members other than those designated by the user. The non-member distribution information can be set, for example, by operating the client terminal 20 by the user.

  Here, FIG. 10 shows an example of a new community creation screen 100 displayed on, for example, the client terminal 20 when creating a new community.

  As shown in FIG. 10, a community name creation field 101, a community introduction sentence creation field 102, a non-member delivery check box 103 and a creation button 104 are displayed on the new community creation screen 100. In the community name creation field 101, a community name created by the user is input. In the community introduction sentence creation field 102, an introduction sentence for introducing the community to other users is input.

  Next to the non-member distribution check box 103, a character string “Do not distribute this community to non-members” is displayed. For example, when the user operates the client terminal 20 to check the non-member distribution check box 103 and a new community is created, the new community information indicating the new community includes a user other than the member specified by the user. The non-member distribution information indicating that notification is not sent to is added. As a result, the new community created here is not distributed (notified) to members other than those designated by the user.

  On the other hand, when a new community is created without checking the non-member distribution check box 103, the new community information indicating the new community is distributed to the members other than the member specified by the user. Information is added. Thereby, the new community created here is distributed (notified) to members other than the members designated by the user.

  When necessary items are input to the community creation field 101, the community introduction sentence 102, or the non-member distribution check box 104, and the user operates the client terminal 20 and presses the creation button 104, a new community is created. .

  Returning to FIG. 9 again, when the determination unit 572 indicates that the non-member delivery information added to the new community information is to be notified to users other than the designated member (YES in step S24), the new community It is determined whether or not the keyword stored in the community information storage unit 422 in association with the information matches the keyword indicated by the user interest information stored in the user information storage unit 421 (step S25). With this process, the determination unit 572 determines whether to notify the user of a new community.

  If it is determined that the determination unit 572 matches the keyword indicated by the user interest information (YES in step S25), that is, if it is determined to notify the user of a new community, the keyword indicated by the user interest information Is identified with reference to the user information storage unit 421 (step S26).

  Next, the message transmission / reception unit 52 selects the new community indicated by the new community information stored in the community information storage unit 422 by the user specified in step S26 and the user specified by the user who created the new community ( Member). In this case, the message transmission / reception unit 52 transmits, for example, a recommendation message including a community introduction sentence of the new community to the client terminal 20 operated by the specified user and the specified user (step S27).

  On the other hand, when the non-member distribution information added to the new community information indicates that the user other than the designated member is not notified (NO in step S24), the new community indicated by the new community information is the designated community. Only members are notified. Similarly, when it is determined that the keyword does not match the keyword indicated by the user interest information (NO in step S25), the new community is notified only to the designated member.

  Next, a processing procedure for notifying the user of a new message when a new message is posted will be described with reference to the flowchart of FIG.

  First, when a new message is posted by the user operating the client terminal 20, the message operation unit 55 inputs message information indicating the new message (hereinafter referred to as new message information) via the Web server 62. (Step S31). The message operation unit 55 stores the input new message information in the message information storage unit 423 and outputs the new message information to the recommended information distribution determination unit 57.

  The extraction unit 571 of the recommendation information distribution determination unit 57 extracts a keyword from the new message by performing morphological analysis on the new message indicated by the new message information output by the message information operation unit 55 (step S32). At this time, for example, the extraction unit 571 extracts all character strings (nouns) included in the title of the new message as keywords. In addition, the extraction unit 571 extracts, for example, a character string included in the body of the new message as a keyword that has an appearance frequency higher than a certain value.

  The extraction unit 571 stores (registers) the extracted keyword in the message information storage unit 423 (step S33).

  Next, the determination unit 572 of the recommendation information distribution determination unit 57 specifies the community where the new message indicated by the new message information stored in the message information storage unit 423 is posted by the user who created the community. It is determined whether notification is possible for members other than members (step S34). At this time, the determination unit 572 refers to the community information storage unit 422 and executes a determination process based on the non-member distribution information added to the community information indicating the community where the new message is posted.

  Next, the determination unit 572 notifies a user other than the specified member of the non-member distribution information added to the community information indicating the community where the new message stored in the message information storage unit 423 is posted. If it is indicated (YES in step S34), it is determined whether or not the new message indicated by the new message information can be notified to members other than those specified by the user who created the new message (step S35). At this time, the determination unit 572 executes determination processing based on the non-member distribution information added to the new message information.

  This non-member distribution information is the same as the member distribution information added to the community information described above, and can be set by, for example, the user operating the client terminal 20 when creating a new message.

  Next, the determination unit 572 indicates that the non-member delivery information added to the new message information stored in the message information storage unit 423 is to be notified to a user other than the designated member (in step S35). YES), it is determined whether or not the keyword stored in the new message information storage unit 423 in association with the new message information matches the keyword indicated by the user interest information stored in the user information storage unit 421. (Step S36). With this process, the determination unit 572 determines whether to notify the user of a new message.

  When it is determined that the determination unit 572 matches the keyword indicated by the user interest information (YES in step S36), the user associated with the keyword indicated by the user interest information is referred to the user information storage unit 421. (Step S37).

  Next, the message transmission / reception unit 52 transmits a new message indicated by the new message information stored in the message information storage unit 423 to the user specified by the user identified in step S36 and the user who created the new message ( Member). In this case, the message transmission / reception unit 52 transmits, for example, a recommendation message including a message to the client terminal 20 operated by the specified user and the specified member (step S27).

  On the other hand, when the non-member delivery information added to the community information indicating the community to which the new message is posted indicates that notification is not made to users other than the designated member (NO in step S34), the new message is designated. Only notified members are notified. In addition, when the non-member delivery information added to the new message information indicates that the user other than the designated member is not notified (NO in step S35), the new message is notified only to the designated member. . Similarly, when it is determined that the keyword does not match the keyword indicated by the user interest information (NO in step S36), the new message is notified only to the designated user.

  Next, a processing procedure for notifying the user A of the new message when a new message is posted will be described in detail with reference to FIG. At this time, it is assumed that the user A is a member belonging to the communities A, B, and C, for example.

  Here, it is assumed that the user A refers to the messages 110, 111, and 112. The message 110 is a message posted to the community A, for example. The message 111 is a message posted to the community B, for example. The message 112 is a message posted to the community C, for example.

  When the messages 110, 111, and 112 are referred to by the user A, the extraction unit 571 of the recommended information distribution determination unit 57 extracts keywords from the character strings included in the messages 110, 111, and 112.

  For example, it is assumed that the keywords “Java” and “character string” are extracted from the message 110. Further, for example, it is assumed that the keyword “meeting” is extracted from the message 111. Further, it is assumed that, for example, the keywords “system”, “trouble”, “stop”, and “method” are extracted from the message 112. These extracted keywords are stored in the user information storage unit 421 as keywords of interest to the user A.

  The extracted keywords are stored in the message information storage unit 423 in association with message information indicating the messages 110, 111, and 112.

  Further, the extraction unit 571 extracts keywords that are interesting to the user A from the profile 113 of the user A indicated by the user information stored in the user information storage unit 421.

  For example, it is assumed that the keywords “software”, “development”, and “Java” are extracted from the profile of the user A. The extracted keyword is stored in the user information storage unit 421 as a keyword that is interesting to the user A, similarly to the keyword extracted from the message referred to by the user A.

  That is, the keywords extracted from the messages 110, 111, and 112 referred to by the user A and the profile 113 of the user A are the keywords 114 that are interesting to the user A shown in FIG.

  Assume that new messages 115 and 116 are posted. It is assumed that the new messages 115 and 116 can be notified to users other than the designated members. Further, it is assumed that the user A is not a member designated by the user who created the new messages 115 and 116.

  In this case, it is assumed that the extraction unit 571 extracts, for example, the keywords “gourmet”, “information”, “ZZZ”, and “store” from the message 115. In this case, the keyword extracted from the message 115 does not match the keyword 114 that is of interest to the user A. In other words, the keyword 114 that is of interest to the user A does not have a keyword that matches the keyword extracted from the message 115. In this case, the recommendation message for notifying the message 115 is not transmitted (distributed) to the user A.

  On the other hand, it is assumed that the extraction unit 571 extracts, for example, the keywords “programming”, “software”, and “development” from the message 116. In this case, the keywords “software” and “development” extracted from the message 116 coincide with “software” and “development” included in the keyword 114 of interest to the user A. In this case, a recommendation message for notifying the message 116 is transmitted (distributed) to the user A. In the example of FIG. 12, the case where there are two matching keywords has been described. However, for example, if one or more matching keywords exist, a recommendation message is transmitted (distributed) to the user A.

  FIG. 13 shows a display example when a recommendation message for notifying the user of a newly posted message is displayed on the display screen 120 of the client terminal 20, for example.

  As shown in FIG. 13, for example, a character string “This message has been posted” is displayed at the top of the display screen 120. For example, in the central part of the display screen 120, for example, a title and text of a newly posted message are displayed. By checking the display screen 120, the user can check the content of the newly posted message.

  FIG. 14 shows a display example when a recommendation message for notifying the user of a newly created community is displayed on the display screen 130 of the client terminal 20, for example.

  As shown in FIG. 14, for example, a character string “This kind of community has been created” is displayed at the top of the display screen 130. Further, for example, in the central portion of the display screen 120, the community name and introduction text (text) of the newly created community are displayed. The user can check the contents of the newly created community by checking the display screen 130.

  In the present embodiment, the keyword interested in the user has been described as a configuration in which the extraction unit 571 of the recommendation information distribution determination unit 57 automatically extracts and stores the keyword in the user information storage unit 421. A configuration in which setting such as addition or deletion is executed by the user operating the client terminal 20 may be adopted.

  FIG. 15 shows a setting screen 140 displayed on the client terminal 20 when, for example, the user A sets a keyword of interest to the user A (keyword indicated by the user interest information) by operating the client terminal 20. An example is shown.

  As shown in FIG. 15, the setting screen 140 displays keywords (character strings) stored (set) in the user information storage unit 421 as keywords that are currently of interest to the user A. In the example of FIG. 15, the keywords “system”, “software”, “Java”, “method”, “development”, “conference”, and “trouble” are displayed.

  A check box 141 corresponding to each keyword is provided next to each of these keywords. Here, it is assumed that the user A checks the check box 141 and presses the delete button 142. In this case, the user interest information indicating the keyword corresponding to the checked check box 141 is deleted from the user information storage unit 421.

  Further, it is assumed that the user A inputs a keyword to be added as a keyword that is interesting to the user A in the new keyword input field 143 and presses the setting button 144. In this case, the keyword input in the new keyword input field 143 is added (stored) to the user information storage unit 421 as a keyword of interest to the user A.

  As described above, in the knowledge accumulation support system 50 according to the present embodiment, the keyword extracted from the newly created community or the newly posted message and the user interest information stored in the user information storage unit 421 are used. It is determined whether or not the displayed keywords match. If it is determined that the keywords match, a new community or new message is notified to the user associated with the keyword based on the user interest information. This makes it possible to notify the user of the content of the community or message that is of interest to the user in real time. Therefore, the user can obtain a useful community or message without performing an operation such as a search, for example, by confirming the content of the notified community or message.

  In this embodiment, since the non-member distribution information is added to community information indicating a newly created community or message information indicating a newly posted message, the user is designated by the user. It is possible to set whether or not to notify the user other than the member of the community or message. Thereby, for example, when a user creates a community that needs to maintain security or posts a message, the community or message can be prevented from being notified (distributed).

  In the present embodiment, keywords that are of interest to the user are extracted in accordance with the profile of the user input by the user or a message referenced by the user. As a result, for example, the user can automatically store (register) keywords that are of interest to the user without operating the client terminal 20 and inputting the keywords one by one. In addition, keywords that are automatically extracted can be customized by deleting unnecessary keywords or adding keywords that the user is interested in, so that the keywords that are of interest to the user can be registered more reliably. can do.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG. Note that the hardware configuration of the client-server system including the knowledge storage support system according to the present embodiment is the same as that of the first embodiment described above, and a description thereof will be omitted. The same applies to the following embodiments.

  FIG. 16 is a block diagram mainly showing a functional configuration of the knowledge storage support system 500 according to the present embodiment. The same parts as those in FIG. 2 are denoted by the same reference numerals, and detailed description thereof is omitted. Here, parts different from FIG. 2 will be mainly described.

  The knowledge storage support system 500 according to the present embodiment is characterized in that the user information processing unit 58 includes a rule setting unit 581 in addition to the first embodiment described above.

  The rule setting unit 581 sets a rule (information distribution rule) for determining whether or not to notify a community or a message in association with the user, for example, according to a user operation. The rule is applied to a user who is set in association with the rule. The rule setting unit 581 stores (registers) rule information indicating the set rule in association with each user to which the rule is applied in the user information storage unit 431 included in the data unit 43.

  The determination unit 592 of the recommendation information distribution determination unit 59 determines whether, for example, a new community or a new message conforms to the rules set by the rule setting unit 581. If the new community or new message conforms to the rule, the determination unit 592 determines to notify the user of the new community or new message.

  In addition, the determination unit 592 determines whether community information indicating a community conforming to the rule set by the rule setting unit 581 or message information indicating a message exists in the community information storage unit 422 or the message information storage unit 423. Execute the process.

  FIG. 17 shows an example of the data structure of the rule information stored in the user information storage unit 431. In the rule information, a user ID and a rule applied to the user indicated by the user ID are shown in association with each other.

  In the example illustrated in FIG. 17, the user ID “A” and the rule “rule 1” are shown in association with each other. Further, the user ID “B” and the rule “rule 2” are shown in association with each other. Similarly, the user ID “C” and the rule “rule 3” are shown in association with each other.

  Here, the rules indicated by the rule information will be specifically described. The rules indicated by the rule information include the following first to fifth rules. The first rule indicates that notification (distribution) is made when a specified keyword is included in the community name of the community or the title of the message. When the first rule is set, the determination process is executed based on the result of the morphological analysis of the community name or the message title.

  The second rule indicates that a community created by a designated user or a posted message is notified. When the second rule is set, for example, information indicating the user who created the community indicated by the community information included in the community information or a message indicated by the message information included in the message information is displayed. The determination process is executed based on the created information indicating the user.

  The third rule is to notify a message whose number of message references (the number of messages being referred to by the user) is greater than or equal to the number of messages indicated by the message information stored in the message information storage unit 423. Indicates to do. When the third rule is set, for example, the determination process is executed based on the reference information stored in the user information storage unit 431.

  The fourth rule is that the community activity level (the number of messages posted to the community for one week, for example) out of the communities indicated by the community information stored in the community information storage unit 422 is greater than or equal to the specified number. Community indicates to notify. When the fourth rule is set, for example, based on information indicating the community to which the message indicated by the message information included in the message information stored in the message information storage unit 423 is posted. Determination processing is executed.

  The fifth rule is that, of the messages indicated by the message information stored in the message information storage unit 423, the messages whose number of replies to the message (the topic indicated by) is more than the specified number are notified collectively. Show. That is, when the designated number of replies is 3, for example, when three reply messages are posted for one message, the four messages are notified together. When the fifth rule is set, the determination process is executed based on, for example, the message title indicated by the message information.

  Of the first to fifth rules described above, the first and second rules are rules for new communities or new messages. On the other hand, the above-described third to fifth rules are rules for a community indicated by community information stored in the community information storage unit 422 or the message information storage unit 423 or a message indicated by message information. Descriptions of rules other than the first to fifth rules described above are omitted.

  Next, a processing procedure for notifying the user of a new community when a new community is created by applying the rules set by the rule setting unit 581 will be described with reference to the flowchart of FIG. The rule applied here is a rule for a new community such as the first or second rule described above.

  First, steps S41 to S46 corresponding to steps S21 to S26 shown in FIG. 9 are executed.

  Next, the determination unit 592 of the recommendation information distribution determination unit 59 sets the new community indicated by the new community information stored in the community information storage unit 422 according to the rule indicated in association with the user specified in step S46. It is determined whether or not they match (step S47). The determination unit 592 performs determination processing based on the rule information stored in the user information storage unit 431. With this process, the determination unit 592 determines whether to notify the user of a new community.

  When it is determined by the determination unit 592 that the new community conforms to the rule (YES in step S47), the message transmission / reception unit 52 determines the user specified in step S46 and the user specified by the user who created the new community. The new community is notified (step S48).

  On the other hand, when the determination unit 592 determines that the new community does not conform to the rule (NO in step S47), the new community is notified only to the user specified by the user who created the new community.

  Although the processing procedure for notifying a new community has been described with reference to FIG. 18, the processing in step S47 in FIG. 18 described above is added to the processing in FIG. Therefore, detailed description of the processing procedure for notifying a new message is omitted.

  Next, referring to the flowchart of FIG. 19, the rules set by the rule setting unit 581 are applied, and the community indicated by the community information stored in the community information storage unit 422 is notified to the user A, for example. A processing procedure to be performed will be described. The rule applied here is a rule for the community indicated by the community information stored in the community information storage unit 422 such as the fourth rule described above.

  First, the determination unit 592 determines whether or not community information indicating a community that conforms to the rule indicated in association with the user A by the rule information stored in the user information storage unit 431 exists in the community information storage unit 422. Is determined (step S51).

  When it is determined that there is community information indicating a community that conforms to the rule (YES in step S51), the determination unit 592 acquires the community information from the community information storage unit 422 (step S52).

  The determination unit 592 performs the processes of steps S53 to S55 corresponding to steps S24 to S26 illustrated in FIG. 9 for the acquired community information.

  On the other hand, if it is determined in step S51 that there is no community information indicating a community that conforms to the rule, the process ends.

  When the determination result is NO in step S53 or S54, the community indicated by the community information stored in the community information storage unit 422 is the member specified by the user who created the community. Since it is already notified when it is created, the community information storage unit 44 recommendation message is not transmitted.

  In FIG. 19, the processing procedure for notifying the community indicated by the community information stored in the community information storage unit 422 has been described, but the message indicated by the message information stored in the message information storage unit 423 is notified. In this case, the same is true, and detailed description thereof is omitted.

  As described above, in the knowledge storage support system 500 according to the present embodiment, by setting the rules to be applied for each user, compared with the knowledge storage support system 50 according to the first embodiment described above. It becomes possible to notify a new community or a new message that is more useful to the user.

  In this embodiment, not only a new community or a new message, but also a rule out of messages indicated by community or message information indicated by community information stored in the community information storage unit 422 or the message information storage unit 423. It is possible to notify the user of a community or a message that conforms to the rules set by the setting unit 581.

[Third Embodiment]
Next, a third embodiment of the present invention will be described with reference to FIG. FIG. 20 is a block diagram mainly showing a functional configuration of the knowledge storage support system 501 according to the present embodiment. Note that, like FIG. 16, the same reference numerals are given to the portions, and detailed description thereof will be omitted. Here, portions different from FIG. 16 will be mainly described.

  In addition to the second embodiment described above, the knowledge storage support system 501 according to this embodiment is characterized in that the recommended information distribution determination unit 60 includes a summary creation unit 601.

  The summary creation unit 601 creates a summary of a message indicated by community introduction text or message information of a community indicated by community information.

  The message transmission / reception unit 521 notifies the user of the summary created by the summary creation unit 601, for example.

  Next, a processing procedure for notifying the user of the summary of the community introduction sentence of the new community when the new community is created will be described with reference to the flowchart of FIG.

  Here, it is assumed that a rule including a rule indicating “notify (distribute) summary” is set by the rule setting unit 581 as a rule applied to the user A, for example.

  First, steps S61 to S67 corresponding to steps S41 to S47 shown in FIG. 18 are executed. It is assumed that the user identified in step S66 is user A.

  Here, as a rule applied to the user A, a rule indicating “notify (distribute) summary” is set as described above.

  The summary creation unit 601 of the recommended information distribution determination unit 60 follows the rules applied to the user A as described above, and introduces a community introduction text (text) of the new community indicated by the new community information stored in the community information storage unit 422. ) Is created (step S68). Here, the summary creation unit 601 creates a summary from the first sentence of a sentence composed of character strings included in the community introduction sentence, excluding, for example, a greeting sentence.

  The message transmission / reception unit 52 notifies the summary created by the summary creation unit 601 to the member specified by the user identified in step S56 and the user who created the new community (user). In this case, for example, the message transmission / reception unit 52 transmits a recommendation message including a summary created by the summary creation unit 601 to the identified user and the client terminal 20 operated by the designated user (step S69).

  Note that, for example, a rule may not be applied to a member specified by a user who created a new community, and the new community may be notified as it is instead of a summary.

  In FIG. 21, the processing procedure for notifying the summary of the community introduction sentence of the new community has been described. However, since the same applies to the case where the summary of the text of the new message is notified, detailed description thereof is omitted. The same applies to the case where the community information indicated by the community information stored in the community information storage unit 422 or the message information storage unit 423 in the second embodiment described above or the message summary indicated by the message information is notified. In addition, the process of step S68 in FIG. 21 is added to the process shown in FIG. Therefore, the detailed description is abbreviate | omitted.

  Next, a processing procedure for notifying the user A of a summary of the new message when a new message is posted will be described in detail with reference to FIG.

  It is assumed that keywords “Java”, “software”, “development”, “conference”, “trouble”, and “method” are stored in the user information storage unit 431 as keywords of interest to the user A, for example. . For example, as a rule applied to the user A, a rule (fifth rule) indicating that “when three or more replies are notified (delivered) together” and “notify (distribute) a summary” ”(Sixth rule) is set.

  Here, for example, a case where the message 200 or 210 is posted and stored in the message information storage unit 423 is assumed. At this time, the topic indicated by the message 200 is set as topic 1, and the topic indicated by the message 210 is set as topic 2. 22 are reply messages to the message 210 (topic 2 indicated by). Here, it is assumed that the new messages 200 and 210 can be notified to users other than the designated members. Further, it is assumed that the user A is not a member designated by the user who created the new messages 200 and 210.

  First, the determination unit 592 of the recommendation information distribution determination unit 59 determines whether to notify the user A about the message 200. In this case, for example, if the keyword “Java” is extracted from the message 200, the keyword “Java” is included in the keyword that is interesting to the user A. However, there is no reply message for topic 1 indicated by message 200. That is, the message 200 does not conform to the above-described fifth rule applied to the user A.

  Therefore, the determination unit 592 determines not to notify the user A of the message 200. Therefore, the message 200 is not notified (distributed) to the user A.

  On the other hand, the determination unit 592 determines whether to notify the user A about the message 210. In this case, for example, if the keyword “Java” is extracted from the message 210, the keyword “Java” is included in the keyword that the user A is interested in. Further, there are four reply messages (messages 220 to 250) for the topic 2 indicated by the message 210. That is, the message 210 conforms to the fifth rule described above applied to the user A.

  Therefore, the determination unit 592 determines to notify the user 210 of the message 210. Therefore, the message 210 is notified (distributed) to the user A.

  Here, when it is determined by the determination unit 592 that the notification is made, the summary creation unit 601 creates each summary of the messages 210 to 250 according to the fifth and sixth rules described above.

  The message transmission / reception unit 521 transmits (distributes) to the user A a recommendation message including a summary of the messages 210 to 250 created by the summary creation unit 601.

  FIG. 23 shows an example of the recommendation message 260 transmitted to the user A by the process shown in FIG.

  As shown in FIG. 23, for example, the recommendation message 260 indicates “Such a message has been posted”. The recommendation message 260 indicates the title name (topic name) of the message 210, the summary of the messages 210 to 250 posted on the topic, and the respective posters. By confirming the recommendation message 260, the user can confirm, for example, a plurality of messages posted on one topic (message).

  The sixth rule indicating “notify the summary” as described above is preferably used in combination with a rule such as the fifth rule that notifies a plurality of messages.

  As described above, in this embodiment, by setting a rule indicating “notify summary”, for example, even when a message with a long text is posted, the summary of the message is notified. Therefore, the user can easily confirm the contents. Also, a rule indicating that “notice of summary” and a rule indicating that a plurality of messages such as “notify (distribute) them collectively when there are three or more replies” are notified collectively. By setting these, the user can easily confirm even a plurality of messages.

  In the present embodiment, a description has been given in which a rule indicating “notify summary” is set to create a community introduction or message summary. However, even if the rule is not set, the summary is used. May be configured to notify.

  Further, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
