It is also possible to post a summary article by selecting 242. When the summary button 242 is selected on the display screen 240 and the article 1 is posted, the original article ID for identifying the starting article 101, the previous article ID for identifying the article 1, the starting article, Article relation information including the relation type “summary” of article 1 is stored in the article relation information storage unit 43. In addition, when a summary article is posted (created) by collecting a plurality of articles, it is also possible to specify the plurality of articles from the posting screen for the summary article.

  Here, for example, it is assumed that the user A who has posted the starting article 101 has applied for the approval of the deliverable 102 to the user B who has the authority to approve the deliverable 102. In this case, the applicant of the deliverable 102 is the user A. At this time, for example, it is assumed that the user A posted the starting article 101 on January 8, 2008, and applied for approval of the deliverable 102 on January 11, the same year. Further, for example, the approval (deadline) date of the deliverable 102 designated by the user A is assumed to be January 14, 2008. Note that “design document A2.txt” is attached to the deliverable 102 as an attached file. This “design document A2.txt” is a file created by revising “design document A1.txt” attached to the starting article 101 in the discussion.

  In this case, the interface 51 of the information sharing apparatus 50 inputs the product 102, the applicant information indicating the user A, and the approver information indicating the user B. The deliverable 102, the applicant information, and the approver information are input according to the operation of the user A on the client terminal 20. Moreover, the user B who is an approver is designated by the user A who is an applicant, for example.

  Next, the history extraction unit 53 determines the article search range based on the product 102 input through the interface 51 and the article relation information stored in the article relation information storage unit 43. First, the history extraction unit 53 is an article that is linked to the deliverable 102 based on the deliverable 102 input through the interface 51 and the article related information stored in the article related information storage 43. Thus, the starting article 101 that is the starting point in the discussion in which the deliverable 102 is created is specified. The history extraction unit 53 is an article posted between the posting date included in the identified starting article 101 and the posting date included in the deliverable 102, and is an article linked to the starting article 101. Is determined as the article search range. In the example shown in FIG. 6, articles 1 to 12 are articles corresponding to the article search range. Note that the articles 13 to 19 shown in FIG. 6 are articles that are posted after the deliverable 102 is posted, and therefore do not fall within the article search range here.

  The article selection unit 55, among the articles corresponding to the article search range determined by the history extraction unit 53, the answer destination article posted by the user A who is the applicant and the answer source article that is the answer source of the answer destination article Is selected from the article storage unit 42. In the example illustrated in FIG. 6, an article set 301 including an article 3 posted by the user A and an article 2 that is an answer source article of the article 3 is selected. Similarly, an article set 302 including articles 8 and 9 and an article set 303 including articles 10 and 11 are selected. For example, when the article 11 is a summary article created by collecting other articles, the article set 303 including the article 10 and the article 11 is not selected. In the following description, it is assumed that the article set 301 to the article set 303 are selected.

  The article selection unit 55 determines whether or not the first flag is set in the parameter setting information stored in the parameter setting information storage unit 44.

  When the first flag is set in the parameter setting information, the article selection unit 55 adds all of the selected article sets 301 to 303 to the summary target list, and simply summarizes the summary target list. The data is transmitted to the creation unit 56.

  On the other hand, when the first flag is not set in the parameter setting information, that is, when the second flag is set, the article selection unit 55 includes the selected article set 301 to article set 303. The article set other than the article set posted by the user B whose reply source article is the approver is added to the summary target list. In the example illustrated in FIG. 6, an article 8 (answer source article) included in the article set 302 is posted by the user B. For this reason, the article selection unit 55 adds the article set 301 and the article set 303 other than the article set 302 to the summary target list, and transmits the summary target list to the simple summary creation unit 56. In the following description, it is assumed that the second flag is set in the parameter setting information and the summary target list to which the article set 301 and the article set 303 are added is transmitted to the simple summary creation unit 301.

  The simple summary creation unit 56 creates summary sentences of the article set 301 and the article set 303 included in the summary target list transmitted by the article selection unit 55. The simple summary creation unit 56 creates a summary sentence based on the texts of the articles 2 and 3 included in the article set 301 and the texts of the articles 10 and 11 included in the article set 302. Here, the created summary sentence represents the history of the discussion in which the deliverable 102 was created.

  The summary sentence created by the simple summary creation unit 56 and the product 102 input by the interface 51 are displayed on the client terminal 20 used by the user B who is the approver via the interface 51.

  Here, FIG. 11 shows an example of a display screen when the deliverable 102 is displayed on the client terminal 20 used by the user B who is the approver. As shown in FIG. 11, an article display field 281, an attached file display field 282, and a history button 283 are displayed on the display screen 280. In the article display column 281, for example, the title “request for approval” and the text “Please approve Mr. B” are displayed. The attached file display field 282 shows an attached file “design document A2.txt” attached to the deliverable 102. The user B can open the file of the “design document A2.txt” by operating the client terminal 20 and designating the “design document A2.txt” shown in the attached file display field 282. It is possible to check the contents of the “design document A2.txt” and determine whether to approve it.

  At this time, when the user B wants to refer to the process of creating the “design document A2.txt” when the “design document A2.txt” is approved, the process button displayed on the display screen 280 is displayed. By selecting 283, for example, as shown in FIG. 12, the summary sentence (for example, “zzzzz...”) Created by the simple summary creation unit 56 is displayed in the summary display field 291 of the summary display screen 290.

  By the way, as shown in FIG. 6, for example, after the deliverable 102 is approved by the above-mentioned user B (after the approval date January 14, 2008), the discussion is performed by posting the articles 13 to 19 and the like. After that, a new product (not shown) may be created. Here, for example, it is assumed that the approval of a new product is applied by a user A to a user who has the authority to approve the new product (for example, user C). It is assumed that “design document A3.txt” is attached to the new product as an attached file. The “design document A3.txt” is a file created by revising the “design document A2.txt” attached to the product 102 in a discussion performed with the product 102 as a starting point, for example.

  In this case, similarly to the case where the application for approval of the deliverable 102 described above is applied, a summary sentence indicating the history of the discussion in which a new deliverable is created is created. This summary sentence is displayed on the client terminal 20 used by the user C who is the approver, together with the new deliverable. As a result, the user C who is an approver can confirm the process of creating the “design document A3.txt” attached to the product 2 when the product 2 is approved.

  When the above-described new product is approved by the user C (approver), for example, a summary sentence (hereinafter referred to as the first summary) indicating the history of the discussion performed from the product 102, for example. Or a summary sentence (hereinafter referred to as a second summary sentence) indicating the history of the discussion that was started from the starting article 101 as in the case of the deliverable 102 described above. For example, the configuration may be such that the user C selects it.

  For example, when the user C selects to display the first summary sentence, in the example illustrated in FIG. 6, the article set 304 including the articles 13 and 14, the article set 305 including the articles 16 and 17, A summary sentence (first summary sentence) for the article set 306 including the article 18 and the article 19 is created, and the summary sentence is displayed.

  On the other hand, when the user C selects to display the second summary sentence, summary sentences (second summary sentences) of the article set 301 and the article set 303 to the article set 306 are created, and the summary sentence is created. Is displayed.

  As described above, in the present embodiment, for example, when an approver (e.g., user B) approves a product 102 created by a discussion starting from a starting article 101 posted by a user, An article set including an answer destination article answered by an applicant (for example, user A) of the deliverable 102 and an answer source article that is the answer source of the answer destination article is automatically set as an important article in the process of creating the deliverable 102. A summary sentence representing the history of the discussion is created from the selected article set. In the present embodiment, the created summary sentence is presented to the approver together with the deliverable 102. As a result, when the approver approves the deliverable 102, the approver 102 confirms the presented summary sentence and how the deliverable 102 (“design document A2.txt” attached thereto) can be obtained. You can easily grasp whether it was created.

  In this embodiment, when the approver is the poster of the answer source article, the approver grasps the content of the answer source article and the answer destination article that has been answered to the answer source article. Therefore, the article set including the answer source article is excluded from the summary sentence creation target. Thereby, in this embodiment, even if the deliverable 102 is created in the same discussion, it is possible to create and present a summary sentence suitable for the approver.

  In the present embodiment, for example, when the product 102 is approved and then the discussion is performed, and an application for approval of a new product is applied, the approver who approves the new product is requested. Thus, it is possible to select to display either the first summary sentence or the second summary sentence. Thereby, the summary sentence according to the request | requirement of the approver who approves a new deliverable can be displayed.

  Note that the present invention is not limited to the above-described embodiment as it is, 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.
