Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same reference numerals are given to the same components, and the description will be omitted as appropriate.

[First embodiment]
FIG. 1 is a block diagram illustrating an information management apparatus 2000 according to the first embodiment of the present invention together with its use environment. In FIG. 1, arrows indicate the flow of information. Further, in FIG. 1, each block represents a functional unit configuration, not a hardware unit configuration.

The information sharing system 3000 includes an information management device 2000, a user interest information storage unit 3020, a group configuration information storage unit 3040, and a group interest information storage unit 3060.

<User interest information storage unit 3020>
The user interest information storage unit 3020 stores user interest information. The user interest information is information that associates (associates or associates) the presentation information with the user information. The presentation information is various information provided to the user. User information is information that identifies a user.

<Group configuration information storage unit 3040>
The group configuration information storage unit 3040 stores group configuration information. The group configuration information is information that associates group information with a plurality of user information.

<Group Interest Information Storage Unit 3060>
The group interest information storage unit 3060 stores group interest information.
Group interest information is information relating presentation information and group information.

Further, in the user interest information, the group configuration information, and the group interest information, at least one of the presentation information not related to the user information is further related to the group information related to the user information. It is attached.

<Information management apparatus 2000>
The information management apparatus 2000 includes a search processing unit 2020 and a sharing processing unit 2040.

<< Search processing unit 2020 >>
The search processing unit 2020 acquires user information, and uses the group configuration information to identify group information related to the user information. Further, the search processing unit 2020 uses the group interest information to provide each presentation information related to the specified group information to the user specified by the acquired user information.

<< Share processing unit 2040 >>
The sharing processing unit 2040 acquires the presentation information and uses the group interest information to identify group information related to the presentation information. Furthermore, the share processing unit 2040 provides the acquired presentation information to each user specified by the plurality of user information related to the specified group information using the group configuration information.

<< Specific example >>
2A and 2B are diagrams illustrating examples of a correspondence relationship between user information, presentation information, and group information as a conceptual model. The model in FIGS. 2A and 2B includes a graph in which each piece of information is represented as a node and the relationship between each piece of information is represented as an edge. A node written as Ij (j is an integer) represents presentation information, a node written as Gj (j is an integer) represents group information, and a node written as Uj (j is an integer) is a user. Represents information. Hereinafter, the user specified by the user information Uj is expressed as a user uj, and the group specified by the group information Gj is expressed as a group gj.

The connection between nodes by an edge indicates that there is information relating two pieces of information represented by the nodes at both ends. For example, the fact that the user information U0 and the presentation information I0 are connected by an edge indicates that user interest information relating the user information U0 and the presentation information I0 exists. Similarly, the fact that the user information U0 and the group information G0 are connected at the edge indicates that there is group configuration information relating the user information U0 and the group information G0. Similarly, the fact that the group information G0 and the presentation information I0 are connected by an edge indicates that there is group interest information relating the group information G0 and the presentation information I0.

The model in FIG. 2A schematically represents user information as information belonging to the user information layer 20 and presentation information as information belonging to the presentation information layer 10. Further, the model of FIG. 2B further represents group information as information belonging to the group information layer 30.

Here, this specific example assumes the following situation. First, user u0 and user u1 belong to the same group g0. The presentation information I0 is information related to the group g0 and the user u2. Furthermore, the presentation information I1 is presentation information related only to the user u1.

FIG. 2A is a diagram obtained by modeling the above assumed environment without using group information. In order to represent the relationship between the presentation information I0 and the group g0, the presentation information I0 is connected to each of user information U0 and U1 that specify users belonging to the group g0 at the edge. Further, in order to represent the relationship between the presentation information I0 and the user u2, the presentation information I0 and the user information U2 are connected by an edge. Furthermore, in order to represent the relationship between the presentation information I1 and the user u1, the presentation information I1 and the user information U1 are connected by an edge.

On the other hand, FIG. 2B is a diagram in which the above assumed situation is modeled using group information. The model in FIG. 2B represents a model in which the group information layer 30 is introduced between the two layers of the user information layer 20 and the group information layer 30 indicated by the model in FIG. 2A. The relationship between the presentation information I0 and the group g0 is represented by an edge connecting the presentation information I0 and the group information G0. The fact that users u0 and u1 belong to group g0 is represented by an edge connecting user information U0 and group information G0 and an edge connecting user information U1 and group information G0.

The difference in the presentation information search process between the case of FIG. 2A and the case of FIG. 2B will be described. In the case of FIG. 2A, group information is not used. Therefore, when the user u1 searches, the presentation information I0 related to the user u1 via the group g0 and the presentation information I1 directly related to the user u1 are acquired.

On the other hand, in FIG. 2B, it is assumed that the user u1 performs a search using the search processing unit 2020. In this case, the search processing unit 2020 specifies the group information G0 as the group information associated with the user information U1, and acquires the presentation information I0 associated with the group information G0. As described above, when the search processing unit 2020 is used, the presentation information associated with the user information via the group information is acquired instead of the presentation information directly associated with the user information.

Note that the information management apparatus 2000 according to the present embodiment may additionally include a function for providing presentation information directly related to user information (eg, presentation information I1 related to user information U1). Absent.

Next, the difference in processing when presentation information is acquired between the case of FIG. 2A and the case of FIG. 2B will be described. In the case of FIG. 2A, the presentation information I0 is provided to the users u0, u1, and u2. On the other hand, in the case of FIG. 2B, it is assumed that the sharing processing unit 2040 acquires the presentation information I0. In this case, the sharing processing unit 2040 specifies group information G0 associated with the presentation information I0. Then, the sharing processing unit 2040 provides the presentation information I0 to the users u0 and u1 specified by the user information U0 and U1 associated with the group information G0.

<Action and effect>
According to the present embodiment, the search processing unit 2020 that has acquired the user information provides presentation information related to the user information to the user specified by the user information via the group information. Therefore, by associating a user with a group to which the user belongs using group configuration information, the user can easily acquire information related to the group to which the user belongs. Can do. Therefore, information can be efficiently shared between users belonging to the group. As a result, group activities can be performed efficiently.

Further, the search processing unit 2020 may present information that is related to group information related to the user information, even if the information is not related directly to the user information from the user information. For example, the presentation information is provided to the user specified by the user information. For example, in FIG. 2B, the user information U0 and the presentation information I0 are not directly related. However, the search processing unit 2020 uses the group configuration information indicating the relationship “user information U0, group information G0” and the group interest information indicating the relationship “group information G0, presentation information I0” to the user u0. The presentation information I0 is provided. As a result, the user can acquire presentation information such as “relevant as a group although not personally related”. Therefore, presentation information related to a group can be easily shared between users belonging to the group. As a result, group activities can be performed efficiently.

Further, when the search processing unit 2020 is used, the presentation information associated with the user information is acquired through the group information, not the presentation information directly associated with the user information. For example, in the case of FIG. 2B, when the search processing unit 2020 is used, the user u1 acquires only the presentation information I0 and does not acquire the presentation information I1. In this way, information related to the user as a group is provided to the user, not information related to the user personally. Therefore, since only the information necessary for the group activity can be acquired by using the search processing unit 2020, the user can efficiently perform the activity related to the group.

Further, when the sharing processing unit 2040 acquires the presentation information, the sharing processing unit 2040 provides the acquired presentation information to the user associated with the presentation information via the group information. Therefore, presentation information can be easily shared among users belonging to the same group. Furthermore, since the users who share the presentation information are limited to users belonging to the group associated with the presentation information, the user can acquire only the presentation information necessary as a group. Therefore, the user can efficiently perform activities related to the group.

Further, according to the sharing processing unit 2040, the acquired presentation information is also provided to the user specified by the user information not directly related to the presentation information by the user interest. Specifically, the sharing processing unit 2040 provides the presentation information to the user specified by the user information associated with the group information associated with the presentation information. For example, in FIG. 2B, the user information U0 and the presentation information I0 are not directly related. However, the sharing processing unit 2040 uses the group interest information indicating the relationship “group information G0, presentation information I0” and the group configuration information indicating the relationship “user information U0, group information G0” to the user u0. The presentation information I0 is provided. As a result, the user can acquire presentation information such as “relevant as a group although not personally related”. Therefore, presentation information related to a group can be easily shared between users belonging to the group. As a result, group activities can be performed efficiently.

<Hardware configuration>
Each functional component included in the information management apparatus 2000 is realized as at least one hardware component, for example, individually or in a combined state. In addition, for example, each functional component is realized as at least one software component. In addition, for example, each functional component is realized by a combination of hardware components and software components.

FIG. 3 is a block diagram illustrating a hardware configuration of the information management apparatus 2000. In FIG. 3, the information management apparatus 2000 includes a bus 1020, a processor 1040, a memory 1060, a storage 1080, and a network interface 1100. Note that the information management apparatus 2000 is various computers such as a server machine, a PC (Personal Computer), or a portable terminal.

The bus 1020 is a data transmission path through which the processor 1040, the memory 1060, the storage 1080, and the network interface 1100 transmit / receive data to / from each other. The processor 1040 is an arithmetic processing unit such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). The memory 1060 is a memory such as a RAM (Random Access Memory) or a ROM (Read Only Memory). The storage 1080 is a storage device such as a hard disk, an SSD (Solid State Drive), or a memory card. The storage 1080 may be a memory such as a RAM or a ROM. The network interface 1100 is an interface for the information management apparatus 2000 to communicate with other apparatuses via a network. For example, the information management apparatus 2000 uses the network interface 1100 to communicate with the user interest information storage unit 3020, the group configuration information storage unit 3040, the group interest information storage unit 3060, or a user terminal. However, the method by which the information management apparatus 2000 acquires information from the user interest information storage unit 3020 or the like is not limited to communication via a network.

The search processing module 1220 is a program for causing the information management apparatus 2000 to have the function of the search processing unit 2020. The processor 1040 implements the function of the search processing unit 2020 by executing the search processing module 1220.

The shared processing module 1240 is a program that allows the information management apparatus 2000 to have the function of the shared processing unit 2040. The processor 1040 implements the function of the shared processing unit 2040 by executing the shared processing module 1240.

For example, the processor 1040 reads the above modules onto the memory 1060 and executes them. However, the processor 1040 may execute the modules without reading them onto the memory 1060.

Storage 1080 stores the above modules.

The hardware configuration of the information management apparatus 2000 is not limited to the configuration shown in FIG. For example, each module may be stored in the memory 1060. In this case, the information management apparatus 2000 may not include the storage 1080.

<Processing flow 1>
FIG. 4 is a flowchart illustrating the flow of processing executed by the search processing unit 2020 according to the first embodiment. In step S102, the search processing unit 2020 acquires user information U0. In step S104, the search processing unit 2020 specifies group information G0 related to the user information U0.

Steps S106 to S110 are a loop process A executed for each presentation information related to the group information G0. In step S106, the search processing unit 2020 determines whether there is information that is not yet the target of the loop process A in the presentation information related to the group information G0. If there is no information that is not the target of the loop process A, that is, if the loop process A has already been executed for all presentation information related to the group information G0, the process of FIG. 4 ends. On the other hand, if there is information that is not yet targeted for loop processing A in the presentation information related to the group information G0, the search processing unit 2020 selects one presentation information that is not yet targeted for loop processing A. To do. Then, the search processing unit 2020 performs the process in step S108. Note that the presentation information selected by the search processing unit 2020 is referred to as presentation information Ij.

In step S108, the search processing unit 2020 provides the presentation information Ij to the user specified by the user information U0. Since step S110 is the end of the loop process A, the search processing unit 2020 subsequently executes the process in step S106.

<Processing flow 2>
FIG. 5 is a flowchart illustrating the flow of processing executed by the sharing processing unit 2040 according to the second embodiment. In step S202, the sharing processing unit 2040 acquires the presentation information I0. In step S204, the sharing processing unit 2040 specifies group information G0 related to the presentation information I0.

Steps S206 to S210 are a loop process B executed for each user information Uj related to the group information G0. In step S206, the sharing processing unit 2040 determines whether there is user information that is not yet the target of the loop process B in the user information related to the group information G0. When there is no user information that is not the target of the loop process B, that is, when the loop process B has already been executed for all user information related to the group information G0, the process of FIG. 5 ends. On the other hand, when there is user information that is not yet the target of the loop process B in the user information associated with the group information G0, the sharing processing unit 2040 sets one piece of user information that is not yet the target of the loop process B. select. Then, the sharing processing unit 2040 performs the process of step S208. Note that the user information selected by the sharing processing unit 2040 is referred to as user information Uj.

In step S208, the sharing processing unit 2040 provides the presentation information I0 to the user specified by the user information Uj. Since step S210 is the end of the loop process B, the sharing processing unit 2040 subsequently executes the process in step S206.

Hereinafter, this embodiment will be described in more detail.

<Details of user information>
As described above, the user information is information that identifies a user. For example, the user information is a user ID (identifier), a name, or an e-mail address. Moreover, when a user acquires presentation information using a terminal, user information may be ID of the terminal which a user utilizes, for example. However, as described above, the user information may be information that identifies a user in order to provide the presentation information, and is not limited to the information exemplified above. In addition, the user information may be a combination of a plurality of information (eg, user ID and mail address).

User information may be registered in advance in the information sharing system 3000, or may be registered as needed by a user, an administrator of the information sharing system 3000, or the like. For example, the information management apparatus 2000 includes a user information registration unit that receives registration of user information and a user information storage unit that stores user information. The user information registration unit stores user information received from the user or the administrator of the information sharing system 3000 in the user information storage unit. Note that the user information registration unit and the user information storage unit may be provided outside the information management apparatus 2000.

<Details of presentation information>
As described above, the presentation information is various information provided to the user. For example, the presentation information is character string data, image data, audio data, or moving image data.

The presentation information may be registered in advance in the information sharing system 3000, or may be registered at any time by a user, an administrator of the information sharing system 3000, or the like. For example, the information management apparatus 2000 includes a presentation information registration unit that accepts registration of presentation information, and a presentation information storage unit that stores presentation information. The presentation information registration unit accepts registration of presentation information from the user and stores the received presentation information in the presentation information storage unit. The presentation information registration unit and the presentation information storage unit may be provided outside the information management device 2000.

<Details of group information>
The group information may be registered in advance in the information sharing system 3000, or may be registered as needed by a user, an administrator of the information sharing system 3000, or the like. For example, the information management apparatus 2000 includes a group information registration unit that receives registration of group information, and a group information storage unit that stores group information. The group information registration unit accepts registration of group information from a user or an administrator of the information sharing system 3000 and stores the accepted group information in the group information storage unit. The group information registration unit and the group information storage unit may be provided outside the information management apparatus 2000.

The group represented by the group information may be a group of a plurality of users, and is not limited to the above-mentioned “department in the organization”. For example, a group may represent a task. For example, the task represents work such as road restoration work. In this case, the group configuration information is information that associates a certain task with a user related to the task (for example, a user who processes the task). In this case, the group information indicates a task ID, a task type, and the like. For example, the type of task is a type such as a P (Plan) phase, a D (Do) phase, a C (Check) phase, or an A (Act) phase in the PDCA cycle.

Note that one piece of user information may be associated with multiple pieces of group information. For example, when a group represents a department in an organization, there may be a situation where one person belongs to multiple departments. In addition, when a group represents a task, there may be a situation where one person is engaged in a plurality of tasks.

<Details of group configuration information>
The group configuration information may be registered in advance in the information sharing system 3000, or may be registered as needed by a user, an administrator of the information sharing system 3000, or the like. For example, the information management apparatus 2000 includes a group configuration information registration unit that receives registration of group configuration information. The group configuration information registration unit receives registration of group configuration information from a user or an administrator of the information sharing system 3000 and stores the received group configuration information in the group configuration information storage unit 3040. The group configuration information registration unit may be provided outside the information management apparatus 2000.

The group configuration information may be information that associates user information and group information bidirectionally, or may be information that relates unidirectionally. For example, it is assumed that there is group configuration information that associates user information U0 and group information G0. When the group configuration information associates U0 and G0 bidirectionally, the group information G0 is obtained in the process of “obtaining group information associated with the user information U0”, and “related to the group information G0” User information U0 is acquired in a process of “acquiring attached user information”. On the other hand, it is assumed that this group information is related to U0 to G0 in one direction. In this case, group information G0 is acquired in the process of “acquiring group information associated with user information U0”, but in the process of “acquiring user information associated with group information G0”. User information U0 is not acquired. When associated in one direction, the graph in the model of FIG. 2 is represented as a directed graph rather than an undirected graph.

FIG. 6 is a diagram illustrating group configuration information in a table format. Hereinafter, the table illustrated in FIG. 6 is referred to as a group configuration information table 100. The group configuration information table 100 has three columns: group information 102, user information 104, and relationship direction 106. In FIG. 6, group information 102 indicates a group ID. The user information 104 indicates a user ID. The relation direction 106 represents a direction in which the group information and the user information described above are related. Specifically, when the relationship direction 106 is 0, it indicates a bidirectional relationship, and when the relationship direction 106 is 1, it indicates a one-way relationship from the group information 102 to the user information 104. When the direction 106 is 2, it represents a one-way relationship from the user information 104 to the group information 102. In the group configuration information, when the group information and the user information are always related bidirectionally, the group configuration information table 100 may not have the relationship direction 106.

<Details of user interest information>
As for user interest information, presentation information may be directly related to user information, or “information specifying presentation information” is related to user information, so that user information and presentation information are related. It may be attached. The information specifying the presentation information is, for example, the ID of the presentation information.

The presentation information specified by one “information specifying the presentation information” may be one or plural. For example, when the presentation information is grouped, the information specifying the presentation information is an ID of a group of presentation information (hereinafter, presentation information group ID). The user interest information relates a plurality of pieces of presentation information to one user information by associating a presentation information group ID with the user information. In this case, the information sharing system 3000 separately has information regarding grouping of presentation information. For example, the information sharing system 3000 includes a storage unit that stores information that associates presentation information with a presentation information group ID of a group to which the presentation information belongs.

As another example, the information specifying the presentation information may be partial information (hereinafter, partial information) included in the presentation information. When the presentation information is character string data, the partial information is a specific character string or the like. Further, when the presentation information is image data or moving image data, the partial information is, for example, an image of a specific object. Further, when the presentation information is voice data, the partial information is a specific voice such as a voice representing a certain word.

The process of specifying the presentation information including certain partial information may be performed dynamically when providing the presentation information to the user. Further, this specifying process may be performed in advance prior to providing the presentation information to the user. Here, the “process for identifying presentation information including certain partial information” means that, for example, when the partial information is “an image of road X”, an image recognition process or the like is used. This is a process for specifying “presentation information including“.

In the presentation information or the like, when an object in a specific place such as “Road X” is represented, the object may be specified using the position information of the object.

When processing for specifying presentation information including partial information is performed in advance, for example, the information sharing system 3000 includes a storage unit that stores association between partial information and each piece of presentation information including the partial information. Moreover, the process which specifies the presentation information containing a certain partial information may be performed at a specific date and time interval, and may be performed in response to another event. The other event is an event that new presentation information is registered in the information sharing system 3000.

For example, the information specifying the presentation information may be a keyword related to the presentation information. For example, when the “information specifying the presentation information” indicated by the user interest information is a keyword “material Y”, the user interest information is information that associates a plurality of presentation information related to “material Y” with the user information. .

The “process for specifying the presentation information corresponding to a certain keyword” is performed dynamically when providing the presentation information to the user in the same manner as the “process for specifying the presentation information including certain partial information” described above. May be. Further, this specifying process may be performed in advance prior to providing the presentation information to the user. “Processing for identifying presentation information corresponding to a certain keyword” refers to, for example, searching for presentation information stored inside or outside the information sharing system 3000 using the keyword, thereby obtaining the presentation information corresponding to the keyword. This is the process to identify.

In the user interest information, two pieces of information may be associated with each other in a bidirectional manner, similarly to the group configuration information.

FIG. 7 is a diagram illustrating user interest information in a table format. Hereinafter, the table shown in FIG. 7 is referred to as a user interest information table 200. The user interest information table 200 has three columns of user information 202, presentation information 204, and relationship direction 206. The user information 202 indicates a user ID and the like. The presentation information 204 indicates presentation information or information that identifies the presentation information. The relationship direction 206 indicates the direction of association between the user information 202 and the presentation information 204. For example, the record in the first line in FIG. 7 includes user interest information that associates user information U001 and presentation information that is character string data “task Z is progressing one hour behind” in two directions. To express. In the user interest information, when the user information and the presentation information are always associated with each other, the user interest information table 200 may not have the relationship direction 206.

There are various triggers for generating user interest information. For example, user interest information is registered by a user or an administrator of the information sharing system 3000. For example, the user interest information may be registered in the information sharing system 3000 in advance.

For example, the information management apparatus 2000 may include a user interest information generation unit that generates user interest information. Here, in addition to the search processing unit 2020 and the sharing processing unit 2040, the information management device 2000 has a function of accepting a search for presentation information and a function of accepting registration of presentation information regardless of group interest information and the like. Suppose that In this case, when a certain user searches and registers the presentation information, the information management apparatus 2000 generates user interest information that associates the user information that identifies the user with the presentation information. Thereby, user interest information turns into information which relates user information with the presentation information considered to be related with the user specified by the user information.

For example, it is assumed that the user u0 who is transporting goods performs a search with the keyword “prefectural road X-line” for transport route search. In this case, the information management apparatus 2000 generates user interest information that associates the presentation information specified by the keyword “prefectural road X line” with the user information U0.

<Details of group interest information>
The group interest information may be information that directly relates the presentation information to the group information, or the group information and the presentation information are related by associating “information for specifying the presentation information” with the group information. It may be related information. The “information specifying presentation information” indicated by the group interest information is the same as the “information specifying presentation information” indicated by the user interest information.

In the group interest information, two pieces of information may be related bidirectionally or unidirectionally like the group configuration information.

FIG. 8 is a diagram illustrating group interest information in a table format. The table shown in FIG. 8 is referred to as a group interest information table 300. The group interest information table 300 has three columns of group information 302, presentation information 304, and relationship direction 306. The group information 302 indicates a group ID and the like. The presentation information 304 indicates presentation information or information that identifies the presentation information. A relation direction 306 indicates a direction of association between the group information 302 and the presentation information 304. When group information and presentation information are always related bidirectionally in the group interest information, the group interest information table 300 may not have the related direction 306.

There are various opportunities for generating group interest information. For example, group interest information is registered by a user or an administrator of the information sharing system 3000. For example, the group interest information may be registered in the information sharing system 3000 in advance.

<Details of Search Processing Unit 2020>
<< Tips for providing presentation information >>
The search processing unit 2020 acquires user information and processes the user information. Here, there are various opportunities for the search processing unit 2020 to provide the presentation information. For example, the search processing unit 2020 receives a search request including the user information of the user from the user, and provides presentation information as a response to the search request. In this case, the search processing unit 2020 provides presentation information related to the group to which the user belongs to the user who transmitted the search request.

Further, for example, the search processing unit 2020 may acquire user information stored inside or outside the information management apparatus 2000 and perform processing on the acquired user information. In this case, the search processing unit 2020 performs a process of providing presentation information to each user regularly (eg, once in an hour) or irregularly. Here, the timing and frequency of performing this process may be common to each user or may be different for each user. The timing and frequency of obtaining the presentation information may vary depending on the situation where the user is placed and the personality of the user. By making it possible to set the timing and frequency of providing the presentation information, the presentation information is provided according to the situation where the user is placed and the personality of the user. Therefore, the convenience of the information management apparatus 2000 is increased for each user.

When the timing and frequency of providing the presentation information (the timing and frequency of acquiring the user information) are different for each user, the information sharing system 3000 includes the user information and the timing and frequency of providing the presentation information for the user information. And a storage unit for storing information relating to. This storage unit may be inside or outside the information management apparatus 2000. The information management apparatus 2000 periodically provides presentation information to each user using the information stored in the storage unit.

<< Narrowing of presentation information to be acquired >>
The search processing unit 2020 may provide all the presentation information to the user or only some of the presentation information to the user when acquiring the presentation information related to the group information. . For example, the search processing unit 2020 provides only the presentation information whose registered date and time is within a predetermined time (for example, 12 hours) from the current date and time among the obtained presentation information.

For example, the search processing unit 2020 may set an upper limit on the number of pieces of presentation information provided to the user. When the acquired presentation information exceeds the upper limit number, the search processing unit 2020 selects presentation information to be provided to the user. For example, the search processing unit 2020 preferentially selects presentation information with a newer registration date and provides it to the user. Each presentation information may be given a priority in advance by a user or an administrator of the information sharing system 3000. In this case, the search processing unit 2020 preferentially selects presentation information having a high priority.

The predetermined time and the upper limit number are stored in advance inside or outside the information management apparatus 2000. Here, the predetermined time and the upper limit number may be common to all users or may be different for each user. The amount of information to browse may vary from user to user. By storing the predetermined time and the upper limit number for each user, the convenience of the information management apparatus 2000 is enhanced for each user.

Further, the method for narrowing down the presentation information to be provided may be related to the group information related to the presentation information. For example, it is assumed that a group represents a task and the group information indicates any phase in the PDCA (Plan Do Check Action) cycle described above as a task type. Here, for example, since the C phase is a phase for confirming the execution result of the task, mainly necessary information is information indicating a reaction to the task. Therefore, for example, when the presentation information related to the group information is the presentation information specified by the keyword “prefectural road X line”, and the group information indicates the type “C phase of recovery work”. Suppose. In this case, the search processing unit 2020 provides only the presentation information corresponding to “reaction information for the recovery work specified by the keyword of prefectural road X-line” to the user.

<< Providing presentation information >>
The search processing unit 2020 may passively provide the presentation information to the user or may actively provide the presentation information to the user. The method of passively providing information to the user is also called pull-type transmission. The method of actively providing information to the user is also called push-type transmission. For example, a method of providing presentation information at a timing when a search request is received from a user is pull-type transmission. A method of periodically providing presentation information to the user is push-type transmission.

In addition, the specific method by which the search processing unit 2020 provides the presentation information is not particularly limited as long as the user can grasp the contents of the presentation information. For example, the search processing unit 2020 may include various types of information such as sending presentation information in a mail to a user, sending a response message to a HTTP (Hyper Text Transfer Protocol) request acquired from the user. Presenting information in a simple way.

The method for the user to grasp the presentation information is arbitrary. For example, it is assumed that each user has a terminal for obtaining presentation information. In this case, the user grasps the content of the acquired presentation information by looking at the presentation information displayed on the screen of the terminal or listening to the sound reproduced by the terminal.

<Details of Share Processing Unit 2040>
The sharing processing unit 2040 acquires the presentation information and processes the presentation information. Here, there are various opportunities for the sharing processing unit 2040 to obtain the presentation information. For example, the sharing processing unit 2040 may have a function of accepting registration of presentation information by a user or an administrator of the information sharing system 3000. Then, the sharing processing unit 2040 acquires the presentation information registered by the user or the information sharing system 3000 and processes the presentation information.

Further, for example, the sharing processing unit 2040 acquires presentation information that is not yet provided to the user from the presentation information stored inside or outside the information management apparatus 2000, and processes the acquired presentation information. You may go. In this case, in relation to the presentation information, information indicating whether or not the presentation information has already been provided to the user is stored. In this case, the sharing processing unit 2040 performs a process of confirming whether there is presentation information that is not provided to the user periodically (eg, once in a time) or irregularly.

Here, the timing at which this processing is performed may be common for each piece of presentation information, or may vary depending on the type of presentation information. As described above, the presentation information is divided into groups or specified by keywords or the like. Therefore, the information sharing system 3000 associates the timing for performing the confirmation process with each keyword specifying the group ID and the presentation information. Then, according to this timing, the sharing processing unit 2040 has, for each group ID or keyword, whether there is presentation information not yet provided to the user in the presentation information associated with the group ID or keyword. To check. If there is presentation information not yet provided to the user, the sharing processing unit 2040 performs processing for providing the presentation information.

Note that the method by which the sharing processing unit 2040 provides the presentation information to the user is the same as any of the methods by which the search processing unit 2020 provides the presentation information to the user.

[Second Embodiment]
FIG. 9 is a block diagram illustrating the information management apparatus 2000 according to the second embodiment together with its use environment. In FIG. 9, arrows indicate the flow of information. Further, in FIG. 9, each block represents a functional unit configuration, not a hardware unit configuration.

The information management apparatus 2000 of the second embodiment is different from the information management apparatus 2000 of the first embodiment in that it further includes a group interest information generation unit 2060. The group interest information generation unit 2060 generates group interest information. Therefore, first, the group interest information generation unit 2060 determines whether or not the first predetermined condition is satisfied between the presentation information and the group information. Then, the group interest information generation unit 2060 generates group interest information by associating the presentation information with the group information when the first predetermined condition is satisfied.

<Details of the first predetermined condition>
There are various first predetermined conditions. For example, the first predetermined condition defines the relationship between user information related to group information and presentation information. Here, the presentation information and the group information to be determined whether or not the first predetermined condition is satisfied are the presentation information I0 and the group information G0, respectively. In this case, the first predetermined condition is, for example, “a plurality of pieces of user information related to the group information G0 are related to the presentation information I0 by a predetermined number or a predetermined proportion of user information by the user interest information. Is the condition. By using this first predetermined condition, among the users belonging to the group represented by the group information G0, when a predetermined number or a predetermined proportion of users are related to the presentation information I0, the group information G0 The presentation information I0 is associated.

For example, it is assumed that, when a user searches for certain presentation information, user interest information indicating that the user information for specifying the user and the presentation information are related is generated. In this case, the user is considered to be a user who needs the presentation information. And the presentation information which many users who belong to the same group require is highly likely to be the presentation information to be shared by the entire group. The information management apparatus 2000 according to the present embodiment indicates that “a plurality of pieces of user information associated with the group information G0 are associated with the presentation information I0 by a predetermined number or a predetermined proportion of user information by the user interest information. The first predetermined condition is used. Thereby, presentation information required by many users belonging to the same group can be shared by all users belonging to the group. Therefore, information can be efficiently shared between users belonging to the same group.

In addition, for example, it is assumed that the information management apparatus 2000 has a function of “accepting a request for providing presentation information to the entire group”. This function corresponds to, for example, a function of performing information transmission called so-called broadcast or multicast. The information management apparatus 2000 receives this request from a user, an administrator of the information sharing system 3000, or the like. In this case, the first predetermined condition may be a condition that “the function has accepted a request”. For example, when the information management apparatus 2000 receives a request to broadcast the presentation information I0 to the group g0, the group interest information generation unit 2060 indicates that the group information G0 and the presentation information I0 are related to each other. Generate interest information. There is a high possibility that the presentation information requested to be provided to the entire group is information necessary for the group. Therefore, by generating group interest information upon receiving a “request to provide presentation information to the entire group”, it is possible to efficiently share information necessary for the group among members belonging to the group. Become.

The first predetermined condition is stored in a storage unit (not shown) provided in the information sharing system 3000, for example. This storage unit may be inside the information management apparatus 2000 or outside the information management apparatus 2000. The group interest information generation unit 2060 acquires the first predetermined condition from this storage unit. Further, the group interest information generation unit 2060 acquires a first predetermined condition input from outside the information sharing system 3000, or accesses a device external to the information sharing system 3000 to acquire the first predetermined condition. May be.

<Deleting user interest information>
When the group interest information generating unit 2060 generates group interest information indicating that the presentation information and the group information are related to each other, it is referred to as “user information related to the group information, the presentation information”. User interest information indicating the association may be deleted. By doing in this way, the user information and the presentation information are associated with only one of the direct relationship based on the user interest information or the indirect relationship via the group information. Therefore, the amount of information held by the information sharing system 3000 can be reduced.

10A to 10C are diagrams conceptually illustrating processing for deleting user interest information. FIG. 10A is a model representing a situation before the group interest information generation unit 2060 performs processing. The presentation information I1 is associated with user information U0 and U1, respectively. Further, both the user information U0 and U1 are related to the group information G0.

FIG. 10B is a graph showing a situation after the group interest information generation unit 2060 newly generates group interest information. Specifically, the group interest information generation unit 2060 generates group interest information that relates the group information G0 and the presentation information I1. As a result, in FIG. 10B, each of the user information U0 and U1 is directly related to the presentation information I1 by the user interest information and indirectly related to the presentation information I1 through the group information G0. Yes.

FIG. 10C is a graph showing a situation after the group interest information generation unit 2060 performs the process of deleting the user interest information. Specifically, the group interest information generation unit 2060 associates user interest information indicating that the user information U0 and the presentation information I1 are associated, and the user information U1 and the presentation information I1. Two pieces of user interest information indicating “” are deleted. Expressed conceptually, the processing performed by the group interest information generation unit 2060 can be expressed as “processing for changing the edge of a graph on a model”.

Note that the group interest information generation unit 2060 may not delete the user interest information. In this case, the situation after the group interest information generation unit 2060 performs the processing is represented by the graph in FIG. 10B.

<Determination of target presentation information and group information>
The group interest information generation unit 2060 determines presentation information and group information for which group interest information is generated by various methods. For example, the group interest information generation unit 2060 acquires presentation information, and determines whether or not the first predetermined condition is satisfied with the acquired presentation information for each group information. Here, there are various opportunities for the group interest information generation unit 2060 to obtain the presentation information. For example, the group interest information generation unit 2060 acquires the presentation information when new presentation information is registered in the information sharing system 3000. Moreover, the group interest information generation part 2060 may acquire each presentation information regularly or irregularly.

Also, for example, the group interest information generation unit 2060 acquires group information, and determines whether or not the first predetermined condition is satisfied for each presentation information with the acquired group information. Here, there are various opportunities for the group interest information generation unit 2060 to obtain the presentation information. For example, the group interest information generation unit 2060 acquires group information of a group to which the user belongs when the presentation information is searched or registered by the user. Moreover, the group interest information generation part 2060 may acquire each group information regularly or irregularly.

Also, for example, the group interest information generation unit 2060 acquires specific presentation information and specific group information, and determines whether or not a first predetermined condition is satisfied between them. These specific presentation information and group information are input by a user or an administrator of the information sharing system 3000, for example.

<Process flow>
FIG. 11 is a flowchart illustrating the flow of processing executed by the group interest information generation unit 2060 according to the second embodiment. In step S302, the group interest information generation unit 2060 acquires group information G0. In step S304, the group interest information generation unit 2060 acquires the presentation information I0.

In step S306, the group interest information generation unit 2060 determines whether the first predetermined condition is satisfied for the group information G0 and the presentation information I0. When the first predetermined condition is satisfied (step S306: YES), the group interest information generation unit 2060 proceeds to the process of step S308. On the other hand, when the first predetermined condition is not satisfied (step S306: NO), the processing of the group interest information generation unit 2060 shown in FIG. 11 ends.

In step S308, the group interest information generation unit 2060 generates group interest information relating the group information G0 and the presentation information I0.

In step S310, the group interest information generation unit 2060 determines whether or not there is user interest information indicating an association of “user information related to the group information G0, presentation information I0”. When this user interest information exists (step S310: YES), the group interest information generation unit 2060 proceeds to the process of step S312. On the other hand, when this user interest information does not exist (step S310: NO), the processing of the group interest information generation unit 2060 shown in FIG. 11 ends.

In step S312, the group interest information generation unit 2060 deletes the user interest information indicating the association of “user information related to the group information G0, presentation information I0”.

<Action and effect>
The information management apparatus 2000 according to the present embodiment generates group interest information. Here, it is considered difficult to manually generate the group interest information using the first predetermined condition described above. According to the present embodiment, since group interest information is automatically generated, it is easier to relate group information to presentation information than when group interest information must be generated manually. Further, by automatically generating group interest information, it is possible to easily grasp which presentation information is presentation information necessary for the group.

Also, by dynamically generating group interest information, it is possible to keep track of presentation information required as a group even in situations where the group configuration changes. For example, it is assumed that users u0 and u1 belong to the group g0. Based on the fact that the user information U0 and U1 are related to the presentation information I0, the group interest information indicating that the group information G0 and the presentation information I0 are related is generated. Suppose. In this situation, even when the group configuration information is changed, the group interest information is not changed, so that the relationship between the group g0 and the presentation information I0 is maintained even when the user u0 or u1 is moved from the group g0. Be drunk. As described above, the information management apparatus 2000 according to the present embodiment can continue to hold the association between the group and the presentation information recognized as a result of the activities of past users who belonged to the group.

However, the information management apparatus 2000 may delete the group interest information according to a change in the group configuration. For example, in the above example, the information management apparatus 2000 confirms that both the group configuration information relating the user information U0 and the group information G0 and the group configuration information relating the user information U1 and the group information G0 have been deleted. As an opportunity, the group interest information relating the group information G0 and the presentation information I0 may be deleted.

[Third embodiment]
FIG. 12 is a block diagram illustrating an information management apparatus 2000 according to the third embodiment together with its use environment. In FIG. 12, arrows indicate the flow of information. Further, in FIG. 12, each block represents a functional unit configuration, not a hardware unit configuration.

In the third embodiment, the information sharing system 3000 further includes a related group information storage unit 3080. The related group information storage unit 3080 stores related group information. Related group information is information that associates group information with other group information.

The search processing unit 2020 according to the third embodiment includes group information associated with the acquired user information and another group associated with the group information via one or a plurality of related group information. For each piece of information, obtain related presentation information. Then, the search processing unit 2020 provides the presentation information to the user specified by the acquired user information.

FIG. 13 is a diagram illustrating related group information in a table format. Hereinafter, the table shown in FIG. 13 is referred to as a related group information table 400. The related group information table 400 has three columns of first group information 402, second group information 404, and a relation direction 406. The first group information 402 and the second group information 404 indicate a group ID and the like. The relationship direction 406 indicates the direction of association between the first group information 402 and the second group information 404. In the related group information, when the first group information and the second group information are always related in both directions, the related group information table 400 may not have the related direction 406.

<Specific example>
FIG. 14 is a model for explaining the processing performed by the search processing unit 2020 of the third embodiment. In FIG. 14, group information G0 and group information G1 are connected by an edge.
This means that there is related group information relating the groups G0 and G1.

Suppose that the search processing unit 2020 acquires user information U0 in the situation shown in FIG. In this case, the search processing unit 2020 specifies the group information G0 related to the user information U0, and provides the presentation information I1 related to the group information G0 to the user u0. Furthermore, the search processing unit 2020 identifies G1 that is group information related to the group information G0, and also provides the presentation information I2 related to G1 to the user u0. Further, the search processing unit 2020 specifies G2 which is group information related to the group G1, and also provides the presentation information I3 related to G2 to the user u0. As described above, in the third embodiment, the user is associated with the group to which the user belongs through not only the presentation information related to the group to which the user belongs but also one or a plurality of related group information. Presentation information related to another group can also be obtained.

<Scope of target group information>
The search processing unit 2020 includes only group information satisfying a predetermined condition among group information related to the acquired user information and other group information related through one or a plurality of related group information. May be used. Specifically, the search processing unit 2020 selects the second of the group information related to the acquired user information and the other group information related via one or more related group information. The related presentation information is acquired only for the group information satisfying the predetermined condition.

Various conditions are used as the second predetermined condition. For example, the second predetermined condition is the number of group information interposed therebetween. The second predetermined condition will be described with reference to FIG. 15A. FIG. 15A is a graph showing the relationship between group information. Here, the user information acquired by the search processing unit 2020 is user information U0, and the group information associated with the user information U0 is group information G0. Further, it is assumed that the second predetermined condition is “the number of intervening group information is 0”.

In this case, the search processing unit 2020 uses the group information G1, G2, and G3 that are directly related to the group information G0 by the related group information. On the other hand, the search processing unit 2020 does not use the group information G4 and G5 associated with the group information G0 via the group information G3 (there is one group information between them). Therefore, the presentation information provided to the user u0 is the presentation information related to any of the group information G0, G1, G2, and G3.

“The number of group information interposed between group information Gi and group information Gj” is “the number obtained by subtracting 1 from the number of related group information used for associating group information Gi and group information Gj”. It corresponds to. For example, in FIG. 15A, group information G0 and group information G4 are represented by two pieces of related group information: related group information indicating the relationship “G0, G3” and related group information indicating the relationship “G3, G4”. Related. On the other hand, there is one group information (group information G3) interposed between the group information G0 and G4. Therefore, “the number of group information interposed between group information Gi and group information Gj” is “the number obtained by subtracting 1 from the number of related group information used for associating group information Gi and group information Gj”. It becomes. The second predetermined condition may be expressed by “the number of related group information used for associating the group information Gi and the group information Gj”.

Also, the related group information may be weighted, and the second predetermined condition may be expressed using the weight. The second predetermined condition will be described with reference to FIG. 15B. The relationship between groups in FIG. 15B is the same as in FIG. 15A. However, in the case of FIG. 15B, the related group information is weighted. The numerical value shown for each edge indicates the weight of related group information represented by that edge. Here, the second predetermined condition between the group G0 and the group Gi in the example of FIG. 15B is a condition that “the total value of the weights of the edges positioned between the group G0 and the group Gi is 10 or less”. And In this case, group information satisfying this second predetermined condition is group information G2, G3, and G4. On the other hand, the group information G1 and G5 do not satisfy the second predetermined condition. Therefore, in the case of FIG. 15B, the presentation information provided to the user u0 is the presentation information related to one of the group information G2, G3, and G4.

Further, the second predetermined condition may be a condition indicating the type of group. For example, assume that the second predetermined condition is “a group that transports goods”. In this case, the search processing unit 2020, among the group information related to the acquired user information and the other group information related through one or more related group information, “transport goods” Only group information corresponding to “group to be performed” is used.

In addition, when the date and time is related to the group information, the second predetermined condition may be expressed by a condition related to the date and time. For example, when a group represents a task, it is assumed that the group information indicates a task ID and a task execution date. In this case, a condition related to the task execution date and time is designated as the second predetermined condition. For example, the second predetermined condition that “the difference between the task execution date and the current date and time is within one hour” is set.

The second predetermined condition may be defined for each group type. The search processing unit 2020 determines the type indicated by the group information related to the acquired user information, and acquires the second predetermined condition related to the type. For example, it is assumed that a group represents a task and the group information indicates a task type. In this case, the second predetermined condition can be determined for each task type.

As described above, examples of task types include the types of P phase, D phase, C phase, and A phase in the PDCA cycle. In this case, the range of group information to be used may be set for each phase of PDCA by setting the second predetermined condition for each task type.

For example, the following second predetermined condition can be considered. First, in the P phase for making a work plan, it is considered appropriate to make a plan by acquiring information in a certain wide range. For this reason, the second predetermined condition associated with the group information indicating the P phase is a condition that increases the group information to be used. For example, it is possible to increase the group information to be used by increasing the upper limit value of the total edge weight in FIG. 15B. On the other hand, in the D phase in which work is performed, it is often sufficient to have information directly related to the work. For this reason, the second predetermined condition associated with the group information indicating the D phase is set such that less group information is used. For example, it is possible to reduce the group information to be used by reducing the upper limit value of the total value of the edge weights in FIG. 15B.

In addition to the above, the following second predetermined condition can be considered. In general, work performed in each phase in the PDCA cycle is often performed in response to the result of work performed in a phase prior to that phase. Therefore, in each phase, it is considered appropriate to acquire “information related to that phase” and “information related to a phase before that phase (eg, phase related to the previous phase)”. . Therefore, for example, the second predetermined condition associated with the group information of the D phase is a condition that “the task type is the D phase or the P phase”.

Note that the method by which the search processing unit 2020 acquires the second predetermined condition is the same as the method by which the group interest information generation unit 2060 acquires the first predetermined condition, for example.

However, the method of providing information indicating the relationship is not limited to the method of providing information using a graph.

Note that the group correspondence providing unit 2100 may provide the relationship between the group information only for the specific group information and the group information directly or indirectly related to the group information. In this case, for example, the group correspondence providing unit 2100 accepts input of group information, and sets the input group information as the specific group information. Also, for example, the group correspondence providing unit 2100 receives input of user information, acquires group information related to the user information, and sets the group information as the specific group information.

<Action and effect>
According to this embodiment, the relationship between groups is provided to the user. Here, the relationship between groups generated by the related group information generation unit 2080 includes a relationship that is difficult to grasp in advance, unlike a relationship that is previously related as an organizational structure or task plan. sell.

For example, there may be cases where it is more efficient that a plurality of groups operating separately because they are not related in terms of organizational structure actually operate in cooperation. In particular, it is difficult to find hidden relationships that are not represented in the organization structure for groups that have few opportunities for information exchange, such as groups that are active in remote locations. According to the information management apparatus 2000 of the present embodiment, the user sees the relationship between the groups provided by the group correspondence relationship providing unit 2100, so that the hidden relationship between the groups not represented in the organizational structure can be obtained. I can grasp it. Therefore, it becomes possible to cooperate more efficiently between groups.

Also, when a group represents a task, there are the following effects. When planning tasks, it may be difficult to find relationships between all tasks in advance. Therefore, it may be more efficient that a plurality of tasks that are not linked because they are not related in the task plan are actually executed while linked. Hidden associations between tasks that are not represented in the task plan, especially when there are few opportunities for information exchange between members executing each task, for example, because each task is being executed remotely It is difficult to find sex. According to the information management apparatus 2000 of the present embodiment, the user grasps the hidden relationship between tasks not represented in the task plan by looking at the relationship between groups provided by the group correspondence providing unit 2100. can do. Therefore, cooperation between tasks can be performed efficiently.

Furthermore, by grasping the relationship between tasks, it becomes easy to grasp important tasks and tasks that can become bottlenecks. For example, a task associated with many tasks is considered an important task. Further, a task associated with many tasks can be considered as a task that is likely to become a bottleneck. This is because it is assumed that many tasks depend on the task.

Furthermore, when the group information indicates the task execution date and time, the group correspondence providing unit 2100 preferably provides the relationship between tasks and the execution date and time of each task. In this way, the information provided by the group correspondence providing unit 2100 can be used as a material for reviewing task scheduling. For example, when the execution date / time of an important task or a task that may become a bottleneck is set later than the execution date / time of another task, it is considered that the task scheduling needs to be reviewed. This is because it is preferable to preferentially execute an important task or a task that may become a bottleneck. As described above, the correspondence relationship between groups provided by the group correspondence relationship providing unit 2100 can also be used for reviewing task scheduling.

The present invention has been described above with reference to the embodiments, but the present invention is not limited to the above embodiments. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
