FIG. 3 is a block diagram showing the functional configuration of the integrated system 10. As shown in FIG.

The user management system 28 is built in the server 12a, for example, and has a user management function and a user authentication function for a chat system 30 and a document management system 32, which will be described later. This user management system 28 has user mapping, for example, and even if one user registers different user IDs or passwords in the chat system 30 and the document management system 32, it is a common user. is recognized and can be authenticated.

This embodiment has a chat system 30 as a communication system. The chat system 30 is built, for example, on the server 12b. Chat system 30 also manages one or more chat rooms 34, as shown in FIG. The chat room 34 is a place for communicating on a specific theme. In this chat room 34, information such as themes and participating members is managed. Also, in the chat room 34, the message 36 posted in the chat room 34 is displayed in real time together with the poster. The chat system 30 also has an operation history database 38 . The operation history database 38 stores a history of operations performed in each chat room 34 . Information such as contributors, participants, posting dates and times, participation dates and times, and message content is accumulated in the operation history.

The document management system 32 is built in the server 12c, for example, and is a document storage unit used for document management and collaborative editing. This document management system 32 has an operation history database 40 for version management, as indicated by the dotted line in FIG. The operation history database 40 stores the history of operations of the document management system 32 . That is, information such as creator, updater, referrer, creation date/time, update date/time, and reference date/time is accumulated for each document version.

The communication support system 42 is built in the server 12d, for example. This communication support system 42 has a related document extraction module 44 , difference information extraction module 46 , summary information generation module 48 and display change module 50 . A module is a unit for realizing a function by software.

The related document extraction module 44 uses the operation history database 38 of the chat system 30 and the operation history database 40 of the document management system 32 to allow the participants of the chat room 34 to access (create, refer to, or update documents) during a specific period. (meaning to do) is specified, and the document group related to the message 36 posted during a specific period is narrowed down. Whether or not there is a relationship with the messages 36 posted during a specific period is narrowed down by extracting keywords from the messages and calculating word vectors between the keywords and the documents.

The difference information extraction module 46 extracts the difference between the first version and the last version of the documents narrowed down by the related document extraction module 44 in the specific period.
For a document that has not been updated, the document may be divided into parts, for example, sections such as chapters, and difference information may be extracted for the divided parts.

A summary information generation module 48 generates a summary for display using the document differences extracted by the difference extraction module 46 . To summarize is to summarize.

The display change module 50 changes the display method of the summarization generated by the summarization information generation module 48 . As will be described later, the detail of information to be presented is changed according to the amount of information to be presented to the user and the length of the specific period. For example, the subject to be presented may be changed, such as a related document list, a user list, a related word list, a part of an extracted document, or a difference between the extracted documents.

Next, the embodiment will be described in more detail together with the flow chart shown in FIG.

First, in step S10, when the user designates the chat room 34 to be summarized, the designated information is accepted. In the next step S12, when the user designates from which user's viewpoint the summarization is to be performed, the designation information is accepted. Normally, it is the user specified in step S10, but it is also possible to receive summarization from other users' viewpoints.

In the next step S14, the user specified in step S12 specifies a period (specified period) for which the user wants to receive the summarization. The specific period may be a period during which the user wants to receive summarization again, as well as a period during which the user is absent. Also, the specific period may be directly specified by the user, or may be obtained by calculating the period from the user's last logoff to the present.

In the next step S16, the messages of the chat room 34 specified in step S10 during the specific period determined in step S14 are extracted. FIG. 7 shows a group of messages during Member 1's absence.

In the next step S18, posters and participants are listed as related users from the group of messages extracted in step S16. Here, as shown in FIG. 8, the contributors are Taro, Jiro, Saburo, and Hanako, and the participants who have not posted but are participating are Shiro, Goro, and Toshiko. Member 1 is listed.

In the next step S20, the related users identified in step S18 list documents that were accessed during the specific period in step S14 as related document candidates. For example, as shown in FIG. 5, the user's extracts documents accessed by as related document candidates. As shown in FIG. 9, "created document", "edited document", and "referenced document" can be separately extracted.
It should be noted that it is not always necessary to extract the referenced document. Reference documents without updates need not be identified, as the purpose of this embodiment is to present the user with updated document content, as described below.

In the next step S22, the relevance between each related document candidate extracted in step S20 and the message extracted in step S16 is checked. Relevance is checked, for example, by word vector operation with each candidate document, with the message group as one sentence. That is, first, for example, morphological analysis is performed on the message group to extract nouns, and these nouns are used as a group of keywords (meaning keys) as shown in FIG. Next, using the keyword group shown in FIG. 10 as a word vector, the degree of relevance of each document extracted in the step is obtained. The degree of association can be obtained from the number of keywords included in candidate documents.
Note that completely irrelevant documents (documents containing no words at all) may be excluded, or documents with relevance below a certain threshold (for example, documents containing less than XX percent of words) may be excluded.

In the next step S24, from among the related documents obtained in step S22, documents that were created, updated, or referred to during the specific period determined in step S14 are obtained, and the version immediately before the specific period (hereinafter referred to as "old version") is obtained. ) and the version at the end of the specific period (hereinafter referred to as the new version). Differences may be obtained for sections of a document created, updated, or referenced during a specific period.

FIG. 11 shows an example of obtaining the difference between the old version and the new version by using the Linux (registered trademark) diff command for the "ZZZ function specification", for example. For example, "6c6" indicates that the 6th line of the old version has been changed to the 6th line of the new version as follows. Also, 147a152, 159 indicates that the following contents are added as lines 152 to 159 of the new version after line 147 of the old version.

FIG. 12 shows an example of display of updated contents of the "ZZZ function specification" shown in FIG. 11 in another pattern. Changed parts are displayed in a different color, in bold, or in a different font. Also, the deleted portion can be displayed by striking out the deleted portion or the like.

In the next step S26, together with the message 36 during the specific period extracted in step S16, a summary is created so as to show an update summary and presented to the user. The presentation to the user is displayed on the screen of the personal computer 14 used by the user. FIG. 13 shows an example of the created summarization. That is, the contents before and after change are shown for document name-1 and document name-2.

15 and 16 show other display change examples. Another example display modification displays messages related to documents. As shown in FIG. 15, when the user selects a related document of interest, for example document name-1, only messages 36 related to the selected document name-1 are displayed as shown in FIG. . The messages 36 containing the keywords used when extracting the selected document name-1 are narrowed down. This clarifies the relationship between the focused document and the message.
