It is a figure which shows a note list screen typically. It is a figure which shows a notebook detailed screen typically. It is a figure which shows a note preparation screen typically.

  First, an outline of the embodiment will be described. FIG. 1 schematically shows a conventional information sharing method. Conventionally, information sharing using a mailing list, a chat tool, or the like has been performed. In FIG. 1, the users A, B, and C belong to the theme α (specific mailing list, thread, etc.) (also referred to as participation), and the users C and D belong to the theme β. User A registers information α-1 in association with theme α, user B registers information α-2 in association with theme α, and user D registers information β-1 in association with theme β. I have registered. In addition, the user C registers information α-3 in association with the theme α, and registers information β-2 in association with the theme β.

  Each of the information α-1 to the information β-2 is shared between a plurality of users belonging to the associated theme. Usually, only the user belonging to the theme α can refer to the information associated with the theme α, and only the user belonging to the theme β can refer to the information associated with the theme β. Therefore, even if useful information on the theme β exists in the information associated with the theme α, members of the theme β (for example, the user D) cannot refer to the information associated with the theme α. As described above, in the normal information sharing method, the relationship between the theme and the information is one-to-many, and the information barrier occurs between the members of each theme.

  FIG. 2 schematically illustrates an information sharing method according to the embodiment. In the information sharing method according to the embodiment, the information associated with the first theme can be associated with a second theme different from the first theme by a simple operation. For example, the user C who belongs to both the theme α and the theme β can associate the information α-3 with the theme β by a simple operation when the user thinks that the information α-3 is also useful for the theme β. . As a result, the information α-3 can be given to the user D who does not belong to the theme α. Since the disclosure destination of the information α-3 is limited to the members of the theme α and the theme β, the disclosure range of the information can be expanded while limiting the disclosure range.

  FIG. 3 also schematically shows the information sharing method of the embodiment. In the information sharing method according to the embodiment, a user belonging to the first theme can make another user belonging to a second theme different from the first theme belong to the first theme. For example, the user C belonging to the theme α can be set so that the user D belonging to the theme β also belongs to the theme α. The user D who newly belongs to the theme α can browse all information related to the theme α, including information registered in the past in the theme α. If the user D thinks that the information β-1 registered in association with the theme β is useful for the theme α, the user D can also associate the information β-1 with the theme α. As described above, in the information sharing method according to the embodiment, the relationship between the theme and the information is many-to-many, and effective information sharing can be realized.

  In the following description, a “theme” is a unit of information sharing (in other words, a range of information sharing) to which a plurality of users belong. The theme may be, for example, a task, a project, or a problem to be solved in a company, and may be provided in units of a company organization or a customer.

By providing a user interface that allows multiple notes to be viewed flat regardless of the associated theme, as in the latter case, users can be aware that notes associated with one theme are also beneficial to other themes. It will be easier to give.

  A user belonging to a certain theme can input an operation (here, referred to as “user addition operation”) for causing another user who does not belong to the theme to belong to the theme on a management screen (not shown) of the information sharing App. It is. When the user addition operation is input, the user device 12 transmits a user addition request including the ID of the theme and the ID of a user who newly belongs to the theme to the information management device 14. The theme updating unit 42 of the information management device 14 updates the theme storage unit 32 so that the user indicated by the user addition request is associated with the theme indicated by the user addition request.

  As described with reference to FIG. 3, the user C belonging to the theme α (the same applies to the users A and B) can cause the user D belonging to the theme β but not belonging to the theme α to belong to the theme α. it can. When the user D who newly belongs to the theme α browses the theme screen 62 related to the theme α, the theme screen generation unit 50 of the information management device 14 transmits a past note (one or more previously registered notes) associated with the theme α. Is set in the theme note list 72. In addition, the theme screen generation unit 50 sets past chat data associated with the theme α in the theme chat 74.

  Similarly, when the user D who newly belongs to the theme α browses the note list screen 66, the note list screen generating unit 52 of the information management device 14 associates the note α with the theme α in addition to the notes associated with the theme β. The registered past note (one or more notes registered in the past) is set in the user note list 90. As described above, according to the information management apparatus 14, when a user newly belongs to a certain theme, past notes and chats associated with the theme are provided to the user. As a result, the user can check the shared information from the past to the present of the newly belonging theme, and can realize effective information sharing.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process described in the embodiment, and that such modifications are also within the scope of the present invention. Where it is.

  A first modification will be described. Although not mentioned in the above embodiment, the information management device 14 may limit the user who can change the theme associated with the registered note to the owner of the note (in other words, the registrant). Thus, it is possible to prevent the disclosure range of the note from being expanded, contrary to the intention of the note owner.

  For example, the note detail screen generation unit 54 of the information management device 14 compares the user who requested to view the note with the owner of the note, and adds a theme editing icon 86 to the note detail screen 64 if they match. On the other hand, if they do not match, the theme editing icon 86 may be hidden. Further, the note updating unit 44 of the information management device 14 compares the user requesting the change of the theme associated with the note with the owner of the note, and if they match, changes the theme associated with the note (addition, etc.). On the other hand, if they do not match, the change of the theme associated with the note may be suppressed.

  A second modification will be described. Unlike the first modified example, the information management apparatus 14 browses the registered note without limiting the user who can change the theme associated with the note to the owner (in other words, the registrant) of the note. If possible, the user may be allowed to change the theme. Thereby, information sharing can be further promoted.

  For example, the note detail screen generation unit 54 of the information management device 14 may generate a note detail screen regardless of whether the user who requested to view the note matches the owner of the note (even if the owner does not match). The theme editing icon 86 may be added to the icon 64. In addition, the note updating unit 44 of the information management device 14 determines whether or not the user who has requested the change of the theme to be associated with the note matches the owner of the note (even if the owner of the note does not match). May be changed (added, etc.).

  A third modification will be described. When the theme associated with a certain note is changed, the information management device 14 may display the note whose theme has been changed in a manner different from that of another note (that is, a note whose theme has not been changed). For example, the notes whose theme has been changed may be displayed in a prominent manner or in an emphasized manner so as to be easily noticed by the user. Since the note whose theme has been changed is a note that is determined to be highly valuable for sharing, effective information sharing can be realized by increasing the degree of attention of the note.

  For example, when the theme of a certain note is changed, the note updating unit 44 of the information management device 14 may add a predetermined flag indicating the change of the theme to the note data. In the theme note list 72 of the theme screen 62, the theme screen generation unit 50 of the information management apparatus 14 emphasizes the note to which the flag is added from the note to which the flag is not added (for example, a red character or a bold letter). Characters, highlighting, etc.). Similarly, the note list screen generation unit 52 of the information management device 14 arranges the note with the flag added thereto in the user note list 90 of the note list screen 66 in a manner that the note with the flag added is emphasized more than the note without the flag added. May be.

  Any combination of the above-described embodiments and modifications is also useful as an embodiment of the present invention. The new embodiment generated by the combination has the effects of the combined example and modified example. It is also understood by those skilled in the art that the functions to be fulfilled by the components described in the claims are realized by each component shown in the embodiments and the modifications or by their cooperation.
