Description

  The present invention relates to a technical field such as a method of preventing erroneous transmission of electronic data in a server device connected to a network and managing a plurality of projects to which a plurality of users belong.

  2. Description of the Related Art Conventionally, when electronic data such as a document is transmitted, there is a method of transmitting the electronic data by attaching it to an electronic mail via the Internet. In sending electronic data using such an e-mail system, by specifying multiple destinations, it is possible to broadcast the same e-mail. For example, to all members belonging to the project For example, if you want to distribute a document, specifying all members as destinations is convenient because you can send the same electronic data at once.

  By the way, when sending electronic data of project-related materials attached to an e-mail to all members belonging to the project, important confidential information is leaked due to erroneous transmission to those who do not belong to the project. There is a risk that. In particular, due to the diversification of corporate activities in recent years, flexible project management that allows many users to participate in (belonging to) a large number of projects or to frequently participate in and withdraw from multiple projects as needed. Although increasing emphasis is placed on improving efficiency, it is important to know who each user belongs to which project, and how much the recipients are currently participating in the project related to the material attached to the e-mail. It is very difficult to figure out. For example, when an electronic data is attached to an e-mail and sent, the user sets the access authority of the attached electronic data for each sender, so that the mail server can only send electronic data for which the sender has access authority. There is a technique for attaching and transmitting (Patent Document 1). However, with this method, each time an e-mail is sent, the user must check the sending partner and set the access authority of the sending partner, so an access authority setting error occurs and erroneous transmission occurs.

  On the other hand, the security level is set for the electronic data that is sent as an attachment to the e-mail, and the access authority for each security level is set for each sender, and the security set for the e-mail when sending the e-mail. A method has been proposed in which the level is compared with the presence or absence of access authority for the security level of the transmission partner, and transmission is permitted if there is access authority (Patent Document 2).

According to this method, the user does not need to set access authority for each transmission partner, and erroneous transmission due to a setting error or the like can be prevented.

Be able to. In particular, according to the “electronic file creation process” described in detail later, an electronic file created in the project workspace of the project to which the user belongs is accumulated and stored in the work database of the corresponding project.

  Next, the configuration and function of the terminal device 2 will be described with reference to FIG.

  FIG. 3 is a diagram illustrating a schematic configuration example of the terminal device 2.

  The terminal device 2 can be a computer such as a general personal computer, and includes a control unit 21 as a computer composed of a CPU having a calculation function, a working RAM, a ROM for storing various data and programs, and the like.

[3. Operation of each device in groupware system]
Next, the operation of each device in the groupware system S will be described.

[3-1. Processing of server device 1]
The processing of the server device 1 described below is executed by the server processing program of the present invention based on the control of the control unit 11 of the server device 1.

  FIG. 4 is a flowchart showing an “electronic file transmission process” in the control unit 11 of the server device 1.

  As a premise that this “electronic file transmission process” is performed, first, the control unit 11 of the server apparatus 1 functions as a work environment designation receiving unit, and issues a designation of a project workspace from the terminal apparatus 2 operated by the user. Accept. This designation instruction includes a user ID for specifying a user who operates the terminal device 2 and a project ID for specifying a project. The control unit 11 functions as a project specifying unit, and stores a storage unit. Referring to the 12 project databases, the project corresponding to the designated project workspace is identified, and whether the user identified by the user ID belongs to the identified project is determined. Only if the user is logged in to the project workspace. And the control part 11 functions as a transmission reception means, and receives the transmission instruction | indication of an electronic file from the terminal device 2 which a user operates. Next, the process of the flowchart of FIG. 4 is executed.

  First, the control part 11 acquires the information which designates the electronic file to transmit (step S1). Specifically, when the user operates the terminal device 2 to input information specifying an electronic file desired to be transmitted, the control unit 11 is configured to specify information specifying the electronic file via the network and the communication unit 13. Is obtained from the terminal device 2. For example, an electronic file created and stored in the work database of each project in the storage unit 12 is designated and acquired according to “electronic file creation process” described in detail later.

  And the control part 11 determines whether the project ID is provided to the electronic file designated at step S1 (step S2), and when the project ID is provided (step S2: Yes). In step S5, if the project ID is not assigned (step S2: No), the control unit 11 functions as an assigning unit, and assigns the project ID to the electronic file (step S3).

  Here, the project ID assigned to the electronic file will be described. The electronic files stored and stored in the work database of each project in the storage unit 12, that is, the electronic files created in the “electronic file creation process” described in detail later, are stored in the project workspace (work environment) of each project. The project ID corresponding to each project is assigned and stored in the corresponding work database. For example, when the user logs into the workspace PS2 of the project B to which the user belongs and creates an electronic file in the project workspace PS2, the project ID “P2” corresponding to the project workspace PS2 being logged in Is added to the electronic file. The electronic file is stored and stored in the work database “ProB DB” of the corresponding project in the storage unit 12 with the project ID “P2” assigned thereto.

  On the other hand, other than electronic files created in the project workspace, that is, various documents stored in the storage unit 22 of the terminal device 2, for example, documents created offline by the user (for example, documents created at home). Etc., no project ID is given. Therefore, when sending such an electronic file to another user belonging to the project via the server device 1, the project of the project corresponding to the project workspace in which the user is logged in is included in the electronic file. An ID is given in the process of step S4. Thereby, project IDs can be assigned to all electronic files without omission.

  The description of the flowchart will be continued.

  Next, the control unit 11 functions as a user specifying information acquisition unit, and acquires information for specifying a transmission destination user who transmits the electronic file (step S4). Specifically, the user who operates the terminal device 2 inputs the mail address (or user ID or the name of the user whose address is registered) of the destination user who desires to transmit the electronic file, and controls the control unit 11. Receives (acquires) the user ID and the like input via the network and communication unit 13 from the terminal device 2 as information for specifying the destination user.

  Subsequently, the control unit 11 performs a comparison process (project ID comparison process) for comparing the project ID assigned to the electronic file with the project ID of the project to which the user specified as the transmission destination in step S4 belongs. (Step S5). The “project ID comparison process” will be described in detail later.

  As a result of the “project ID comparison process”, it is determined whether or not the mismatch list in which the user whose list does not match the project ID of the project to which the user belongs and the project ID assigned to the electronic file is registered is empty (step S6) When the mismatch list is empty (step S6: Yes), that is, when all the users specified as the transmission destination belong to the project corresponding to the project ID assigned to the electronic file. When the process proceeds to step S10 and the mismatch list is not empty (step S6: No), the control unit 11 functions as a warning presentation data transmission unit, and an electronic file related to the project is transmitted to a person other than the user belonging to the project. Warning information that warns of erroneous transmission is provided. Send alerts presentation data to the terminal device 2 which the user is operating (step S7).

  Subsequently, the control unit 11 determines whether or not a transmission instruction is issued from the terminal device 2 (step S8), and when there is a transmission instruction (step S8: Yes), the process proceeds to step S10 and the transmission instruction is performed. If there is no information (step S8: No), the control unit 11 determines whether information specifying a new transmission destination is transmitted from the terminal device 2 and there is an instruction to re-designate the transmission destination (step S9). . If there is no instruction for re-designating the transmission destination, that is, if there is an instruction to stop transmission (disallow) (step S9: No), the processing ends.

  On the other hand, when there is a re-designation instruction of the transmission destination (step S9: Yes), the process proceeds to step S4, and information specifying a transmission destination user who transmits the electronic file is acquired based on the re-designation instruction. The project ID of the project to which the user redesignated as the transmission destination belongs is compared again with the project ID assigned to the electronic file.

  Next, in step S10, the control unit 11 functions as an electronic data transmission unit, transmits the electronic file attached to the e-mail to the specified transmission destination user (step S10), and ends the process. At this time, when the information for specifying the transmission destination acquired in step S4 is a user ID, the control unit 11 refers to the user database and sends an electronic file to the mail address corresponding to the acquired user ID.

Project ID Comparison Process at Step S5 Next, the “project ID comparison process” at step S5 will be described. FIG. 5 is a flowchart showing the “project ID comparison process” in step S5 in the control unit 11 of the server device 1.

  First, the control unit 11 extracts the project ID assigned to the electronic file (step S21). Next, based on the information specifying the transmission destination acquired in step S4 described above, the project ID to which the transmission destination user belongs is acquired from the project database (step S22), and the project ID extracted in step S21 and in step S22 The acquired project IDs are compared (step S23).

  The control unit 11 functions as a determination unit, and determines whether the project IDs match (is the same) as a result of the comparison in step S23 (step S24).

  According to the example shown in Table 2, for example, the project ID assigned to the electronic file (extracted in step S21) is “P1”, and the destination specified in step S4 is the user ID “U1” “U2” “U4”. Assuming that

  In this case, first, it can be seen from the project database shown in Table 2 that the project ID to which the user with the user ID “U1” belongs is “P1”, “P2”, and “P4”. In this case, the project ID “P1” assigned to the electronic file matches the project ID “P1” to which the user with the user ID “U1” belongs.

  From the project database shown in Table 2, the project ID to which the user with the user ID “U2” belongs is found to be “P1”, “P3”, and “P5”. Also in this case, the project ID “P1” assigned to the electronic file and the project ID “P1” to which the user with the user ID “U2” belongs are the same.

  On the other hand, it can be seen from the project database shown in Table 2 that the project ID to which the user with the user ID “U4” belongs is “P3” and “P4”. In this case, since the project ID “P1” of the electronic file does not match the project ID to which the user with the user ID “U4” belongs, the control unit 11 warns in a later process (step S7 described above). Warning presentation data for presenting information is transmitted to the terminal device 2.

  The description of the flowchart will be continued.

  As a result of the determination in step S24, if the project IDs match (step S24: Yes), the process proceeds to step S26, and if the project IDs do not match (not the same) (step S24: No), The user is added (registered) to the mismatch list (step S25), and the process proceeds to step S26.

  Next, in step S26, it is determined whether or not the comparison of project IDs has been completed for all the transmission destinations acquired in step S4 (step S26), and when the comparison of project IDs is completed (step S26: Yes). When the process is terminated and the process proceeds to step S6 (FIG. 4) and the comparison of the project IDs is not completed (step S25: No), the process proceeds to step S22, and the project IDs of all transmission destinations are changed. Steps S22 to S26 are repeated until the comparison is completed.

Electronic File Creation Processing Next, “electronic file creation processing” when the user creates an electronic file in the project workspace will be described. FIG. 6 is a flowchart showing “electronic file creation processing” in the control unit 11 of the server device 1.

  As a premise that this “electronic file transmission process” is performed, first, the control unit 11 of the server apparatus 1 functions as a work environment designation receiving unit, and issues a designation of a project workspace from the terminal apparatus 2 operated by the user. Accept. This designation instruction includes a user ID for specifying a user who operates the terminal device 2 and a project ID for specifying a project. The control unit 11 functions as a project specifying unit, and stores a storage unit. Referring to the 12 project databases, the project corresponding to the designated project workspace is identified, and whether the user identified by the user ID belongs to the identified project is determined. Only if the user is logged in to the project workspace.

  And in the said project workspace, the control part 11 of the server apparatus 1 functions as a production | generation reception means, and receives the production | generation instruction | indication of an electronic file from the terminal device 2 which a user operates. And the control part 11 functions as a production | generation means, and performs the production | generation process of an electronic file according to the production | generation instruction | indication of the said electronic file. Then, after the generation of the electronic file is completed, the processing of the flowchart of FIG. 6 is executed.

  First, the control unit 11 acquires a project ID that identifies a project in the project workspace in which the user is logged in (step S31). Next, the control unit 11 functions as an assigning unit, assigns the acquired project ID to the generated electronic file (step S32), and ends the process. The electronic file to which the project ID is assigned is stored and saved in the work database of the project corresponding to the project workspace being logged in.

[3-2. Presentation of warning information in terminal device 2]
When the terminal device 2 receives warning presentation data for presenting warning information from the server device 1, the terminal device 2 presents warning information based on the warning presentation data. FIG. 7 shows an example of warning information displayed on the display unit of the terminal device 2.

  In this display example, the user includes a project ID corresponding to the project name: ProB in the designation instruction, transmits it to the server apparatus 1, logs in to the project workspace PS2 of the ProB, and designates the transmission destination “Tanaka Hanako” This is a display example of a warning received when trying to send an electronic file.

  In this example, according to the project database shown in Table 2, the project ID “P2” corresponding to the project work space PS2 is assigned to the electronic file. On the other hand, the user ID for specifying the destination user “Tanaka Hanako” is “U2”, and the project IDs of the projects to which the user belongs are “P1”, “P3”, and “P5”. That is, the project ID “P2” assigned to the electronic file does not match the project IDs “P1”, “P3”, and “P5” of the project to which the destination user “Tanaka Hanako” belongs. Therefore, the terminal device 2 receives the warning presentation data from the server device 1, and the terminal device 2 receives this, and the warning information is displayed on the display unit of the terminal device 2 based on the warning presentation data. In the example shown in FIG. 7, warning information “I am trying to send a file to a different user of the project” is displayed, and the details of the warning include the project ID and destination of the electronic file to be warned. “File affiliation project: ProB” and “User with different project: Tanaka Hanako” are displayed.

  Further, the user who confirms the details of the warning is prompted to select whether to allow transmission (permitted), cancel transmission (not permitted), or change the transmission destination (change transmission destination). The selection is performed via an input / output interface such as a mouse connected to the input / output unit 24 of the terminal device 2, and the selection result is transmitted to the server device 1.

  When the server device 1 receives the selection result, the server device 1 executes determination processing based on the result in step S8 or S9 of the flowchart described above.

  As described above, according to the groupware system S of the present embodiment, the server apparatus 1 associates the project ID corresponding to each project with the user ID corresponding to each user belonging to each project, in the project database. When the user tries to send an electronic file to another user, the project ID assigned to the electronic file is the same as the project ID of the project to which the destination user belongs. If it is not the same, the user who does not belong to the project is configured to send the warning presentation data that warns the user who tried to send the electronic file that the electronic file was sent incorrectly. Prevent information leakage by preventing electronic files from being sent incorrectly It can be.

  Furthermore, the user logs in to the project workspace of the project to which the user belongs, and the electronic file such as the document related to the project generated in the project workspace (work environment) has the project ID of the project corresponding to the project workspace. Since it is configured to be assigned, an appropriate project ID can be assigned to each electronic file without trouble.

  Furthermore, when the project ID assigned to the electronic file is the same as the project ID of the project to which the transmission destination user belongs, the electronic file is transmitted to the transmission destination user. When sending and receiving electronic files between members, since an erroneous transmission check is performed and an authenticated electronic file is sent and received that is regular transmission, not only the user who sent the electronic file, The user who receives this can also get a sense of security.

[4. Other Embodiments]
[4-1. Other Embodiment 1]
In the above-described embodiment, the present invention specifies the user by individually specifying one or a plurality of destinations of the electronic file via the terminal device 2 or by specifying a plurality of destinations at once as a simultaneous transmission. This is an example applied to a configuration in which an electronic file is transmitted to each of the transmission destinations, but is used for a real-time meeting between members belonging to the project group in the project workspace via the terminal device 2 by the user While participating in the video conference function (web conference) to be sent, the conference materials related to the project are transmitted as electronic files to other users participating in the conference (each terminal device 2 operated by another user). The present invention can also be applied to the configuration presented in this manner.

  In the other embodiment 1, each user operates to log in to the project workspace of the project to which the user belongs and participate in the conference as an electronic file of the conference materials related to the project while participating in the web conference. This is an example of the case where the present invention is applied to a configuration in which an electronic file is transmitted to the terminal device 2, received by another terminal device 2, and presented to the display unit of each terminal device 2.

  FIG. 8 is a flowchart illustrating an “electronic file transmission process” in the control unit 11 of the server apparatus 1 according to the first embodiment.

  As a premise that this “electronic file transmission process” is performed, first, the control unit 11 of the server device 1 joins the conference from the terminal device 2 operated by a user who logs in to the project workspace and is participating in the web conference. An electronic file transmission instruction including a presentation instruction message, which is an example of an electronic data presentation instruction message for instructing transmission (presentation) of an electronic file, is received for each terminal device 2 operated by another user. Next, the process of the flowchart of FIG. 8 is executed.

  First, the control unit 11 acquires information specifying an electronic file to be presented at the web conference (step S41). Specifically, each terminal device operated by another user who logs in to the project workspace and participates in the web conference from the terminal device 2 operated by the user who logs in to the project workspace and participates in the web conference 2, information specifying an electronic file desired to be presented is input, and the control unit 11 acquires information specifying the electronic file via the network and the communication unit 13.

  And the server apparatus 1 acquires user ID of all the users who are participating in a web meeting as information which identifies the transmission destination user who should transmit an electronic file (step S42). Specifically, when another user participating in the web conference participates in the conference, the user ID included in the designation instruction when logging in to the project workspace via each terminal device 2 is assigned to the control unit. 11 is acquired via the network and communication unit 13. And the control part 11 should just acquire the user ID acquired at this time as information which identifies a transmission destination user. Note that the mail address associated with the acquired user ID may be acquired as information for specifying the transmission destination user by referring to the user database in the storage unit 12.

  Next, the control unit 11 determines whether or not a project ID is assigned to the electronic file specified in step S41 (step S43), and if the project ID is assigned (step S43: Yes). The process proceeds to step S45, and if the project ID is not assigned (step S43: No), the project ID is assigned to the electronic file (step S44).

  And the control part 11 performs the comparison process (project ID comparison process) which compares the project ID provided to the electronic file with the project ID of the project to which the user designated as the transmission destination in step S42 belongs (step S42). Step S45).

  The “project ID comparison process” in step S43, step S44, and step S45 described above is the same as the method described in detail with reference to FIG.

  As a result of the comparison processing, it is determined whether or not the mismatch list is empty (step S46). If the mismatch list is empty (step S46: Yes), that is, all users designated as the transmission destination (in other words, , All users who participate in the web conference) belong to a project corresponding to the project ID assigned to the electronic file, the process proceeds to step S49. On the other hand, if the mismatch list is not empty (step S46: No), the control unit 11 may transmit an electronic file related to the project to the terminal device 2 operated by a user who does not belong to the project, and may be erroneously transmitted. Assuming that there is a user in the mismatch list, warning presentation data for presenting warning information to warn of erroneous transmission is transmitted to the terminal device 2 that has instructed transmission of the electronic file (step S47). ).

  FIG. 9 shows an example of warning information displayed on the display unit of the terminal device 2.

  This display example is a display example of the display unit of the terminal device 2 that has received the warning presentation data transmitted by the server device 1 in the process of step S47. In this example, while the user is participating in a web conference, the terminal device 2 operated by another user who participates in the conference on the server device 1 to present the electronic file with the project ID “P2” to each user. It is a display example of a warning received when trying to send to.

  In the case of the example shown in the figure, it is described above that “Tanaka Hanako” participating in the web conference does not belong to the project corresponding to the project ID “P2” assigned to the electronic file. Is detected and warned in the “project ID comparison process”. That is, the warning is based on the fact that the project ID “P2” given to the electronic file and the project IDs “P1”, “P3”, and “P5” of the project to which the web conference participant “Tanaka Hanako” belongs do not match. is there.

  As shown in FIG. 9, warning information “Users with different projects are participating in the meeting” is displayed, and as the details of the warning, the project ID and transmission destination of the electronic file targeted for the warning are “ The file affiliation project: ProB "and" Users with different projects: Tanaka Hanako "are displayed.

  The user who confirms the details of the warning further prompts the user to select whether to allow the electronic file to be displayed (permitted) or to cancel the display (not permitted) to the user who does not belong to the project. The user who has instructed the file transmission performs the selection via an input / output interface such as a mouse connected to the input / output unit 24 of the terminal device 2, and transmits the selection result to the server device 1. ing.

  And the control part 11 determines whether the transmission instruction | indication was received from the terminal device 2 (step S48), and when there is no transmission instruction | indication, ie, when there exists an instruction | indication which stops transmission (display) (not permitted) (Step S48: No), the process is terminated.

  On the other hand, when there is a transmission instruction (step S48: Yes), the control unit 11 operates each of the other users participating in the web conference based on the information specifying the transmission destination user acquired in step S42. The electronic file is transmitted to the terminal device 2 together with a presentation instruction message instructing to present the electronic file (step S49), and the process ends. In addition to the configuration in which the electronic file is transmitted by being attached to an e-mail or the like, the electronic file is configured to be transmitted to each terminal device 2 according to the IP address of each terminal device stored in the server device 1. Can do.

  According to such another embodiment 1, while the user is participating in the video conference function (web conference) in the project workspace via the terminal device 2, the conference materials related to the project are electronically filed in the conference. When sending to other participating users and presenting meeting materials, etc., if there are users who have not participated in the project, they are warned that they can send the meeting materials. Therefore, it is possible to prevent a meeting material or the like from being transmitted and presented by mistake to a user who has not participated in the project.

  In the process of step S49, the control unit 11 is configured to transmit the electronic file together with the presentation instruction message instructing each terminal device 2 operated by another user to present the electronic file. Each terminal device 2 that has received can promptly present the conference material and the like related to the electronic file on the display unit, so that a smooth web conference can be managed.

[4-2. Other Embodiment 2]
In the “project ID comparison process” in each of the above-described embodiments, the comparison process is performed based on information such as the project ID and the user ID by referring to the project database.

  Therefore, for example, when the project is for a long period of time, the members who participate frequently change depending on the stage of execution, such as project planning / startup, planning, development, business analysis, and completion. In this case, if the information in the project database is old, there is a possibility that an electronic file related to the project is erroneously transmitted to a user who has already left the project.

  In another embodiment 2, the control unit 11 of the server device 1 further functions as a calculation unit, an update unit, and a deletion notification message transmission unit of the server device of the present invention, and projects according to the degree of participation of each user in the project. A configuration is described in which the database database is deleted and updated to keep the project database always up-to-date, and the effect of preventing erroneous transmission is improved.

  FIG. 10 is a configuration example of the storage unit 12 of the server device 1 according to another embodiment 2.

  The storage unit 12 of the server device 1 according to the second embodiment stores a history database, an event database, and a participation degree calculation rule database in addition to the user database, the project database, and the work database described in the above embodiment. ing. Since the user database, project database, and work database stored in the storage unit 12 are the same as those in the above-described embodiment, description thereof is omitted here.

  The history database, event database, and participation degree calculation rule database stored in the storage unit 12 will be described.

  First, the history database will be described. Table 3 shows an example of the history database.

  The history database includes a project ID, a user ID of a user who belongs to the project associated with the project ID, a total sum of participation indexes indicating the degree of participation of each user in the project, and a predetermined threshold that serves as a criterion for determining as a project leaver Are registered and stored in association with each other.

  The participation index indicates the degree of participation of each user in the project. The server device 1 monitors the activity status of the project by each user logging in to the project workspace. Points are added each time it is performed. The points added for a predetermined period (for example, 7 days) are calculated as the sum of the participation indices in the predetermined period, and are registered in the history database as the sum of the participation indices in the most recent (latest) predetermined period. .

  FIG. 11 is an explanatory diagram of a participation index for an arbitrary project of an arbitrary user. (A) is a graph showing changes in the participation index of each day from March 27 to April 8, and (B) is participation in a plurality of predetermined periods between March 27 and April 8. It is a graph which shows the change of the sum total of an index.

  In the example shown in FIG. 11 (A), it is assumed that the user has been removed from the project on April 6, due to the end of the role in the project, and referring to FIG. 11 (B), April 1 For the first time in the predetermined period of April 7th, the sum of the participation indexes is below a predetermined threshold value set in advance. The predetermined threshold is the sum of the minimum participation indices to be acquired in a predetermined period, and serves as a criterion for determining as a project leaver. An administrative user (such as a project leader or a dedicated point management member who belongs to a project) who manages a project operates the server device 1 or a terminal device 2 that can communicate with the server device 1 via a network. By operating other devices such as a PC, information indicating a predetermined threshold is transmitted to the server device 1 via the network, and the server device 1 acquires the information and stores the information acquired by the control unit 11. This is configured to be stored in the unit 12.

  Then, when the sum of the participation indices in the project is equal to or less than a predetermined threshold, the association between the project database user and the project is deleted and the project database is updated.

  By the way, the “activity related to the project” monitored by the server device 1 is, for example, an action such as sending an email to the project mailing list or participating in a project meeting. The points added to each activity and user will be described in detail in the explanation of the event database and participation degree calculation rule database described below.

  Table 4 shows an example of the event database.

  In the event database, an event name, which is an example of “activity related to a project”, an event type, the date and time when the event is held (executed), and added when an activity (attendance, participation, cooperation, etc.) is performed on the event. Are registered (stored) in association with each other. Since the participation index added according to each “activity related to the project” can be set to a different point according to each activity, weighting according to the activity is possible.

  This information is communicated by the management user who manages the project (such as the project leader or the event database registration specialist who is a member of the project) by operating the server device 1 or via the network with the server device 1 By operating a possible terminal device 2 or other device such as a PC, the server device 1 acquires event name, event type, date and time, participation index information via the network, and the control unit 11 acquires it. What is necessary is just to comprise so that an event database may be constructed | assembled by matching the information which matched with the memory | storage part 12 and registering.

  When a user performs an “activity related to a project”, if the activity is an event registered in the event database, the participation index associated with the event database is added to the point and registered in the event database. If not, points corresponding to “activity related to the project” are added based on the participation calculation rule database described below.

  Next, the participation degree calculation rule database will be described. Table 5 shows an example of the participation degree calculation rule database.

  In the participation degree calculation rule database, for each project, “activity related to the project” and a participation index for the activity are registered (stored) in association with each other.

  Each information to be registered is stored in the management user who manages the project (such as a project leader or a participation index registration specialist who is a member of the project) by operating the server device 1 or the server device 1 and the network. By operating the terminal device 2 and other devices such as a PC that can communicate via the network, the server device 1 acquires information on the activity relating to the project and the participation index for the activity via the network, and the control unit 11 May be configured such that the information obtained by the association is registered in association with the storage unit 12 and the participation degree calculation rule database is constructed.

  By setting up an event database and a participation rate calculation rule database separately, regular "project activities" such as regular conferences are referred to the participation rate calculation rule database and points are added to the participation index, so important meetings and presentations For events that become milestones of projects, etc., refer to the event database and add points to the participation index.

  Thus, for example, when an important meeting is registered in the event database, the participation index can be set at a point higher than the participation index of 7 points of “participating in the meeting” in the participation degree calculation rule database. Even if it is “participating in”, the participation index can be weighted according to the importance of the conference.

  Next, “participation index management process” and “project database update management process” for managing the participation index of each user's project performed in the server apparatus 1 will be described.

  FIG. 12 is a flowchart showing the “participation index management process” in the control unit 11 of the server device 1.

  As a premise that this “participation index management process” is performed, first, the control unit 11 of the server apparatus 1 functions as a work environment designation receiving unit and issues a designation of a project workspace from the terminal apparatus 2 operated by the user. Accept. This designation instruction includes a user ID for specifying a user who operates the terminal device 2 and a project ID for specifying a project. The control unit 11 functions as a project specifying unit, and stores a storage unit. Referring to the 12 project databases, the project corresponding to the designated project workspace is identified, and whether the user identified by the user ID belongs to the identified project is determined. Only if the user is logged in to the project workspace.

  First, the control unit 11 determines whether or not the power of the server device 1 is turned off (step S51). If not turned off (step S51: No), whether or not the user has performed an activity related to the project. Is determined (step S52). Specifically, it is determined whether or not the user has performed an activity related to the project in the logged-in project workspace (work space).

  Next, when the project activity is not performed (step S52: No), the process proceeds to step S51. When the project activity is performed (step S52: Yes), the project workspace in which the user is logged in. The project ID is acquired (step S53).

  Subsequently, the control unit 11 acquires a user ID of a user who has performed an activity relating to the project (step S54), and the control unit 11 determines whether or not the event is registered in the event database of the storage unit 12 (step S54). Step S55). As a result of the determination, if the event is registered in the event database (step S55: Yes), the participation index corresponding to the event is acquired from the event database (step S56), and the event is not registered in the event database. (Step S55: No), the participation index corresponding to the activity related to the project is acquired from the participation degree calculation rule database (Step S57).

  And the control part 11 updates the log | history database of the memory | storage part 12 based on the participation index | exponent acquired in step S56 or step S57 (step S68), and until the power supply of the server apparatus 1 is turned off (step S51 :). Yes), Steps S51 to S58 are repeated.

  Next, “project database update management processing” will be described.

  FIG. 13 is a flowchart showing the “project database update management process” in the control unit 11 of the server device 1.

  This “project database update management process” is executed periodically (for example, every day, every 7 days, every month, etc.) in the server device 1.

  First, the control unit 11 selects a project for calculating the participation index and a user for calculating the participation index from the project database (steps S61 and S62).

  Subsequently, the control unit 11 calculates the sum of the participation indexes for the predetermined period of the user selected in Step S62 for the project selected in Step S61 (Step S63). The calculated sum of participation indexes is registered in the history database in association with the project ID and user ID. Then, the control unit 11 refers to the history database, extracts a predetermined threshold corresponding to the project selected in step S61, and determines whether the calculated sum of participation indexes is equal to or less than the extracted predetermined threshold (step S64). ).

  As a result of the determination, if the sum of the participation indices is equal to or less than the predetermined threshold (step S64: Yes), there is a user whose sum of the participation indices is equal to or less than the predetermined threshold with respect to an administrative user who manages the project such as a project leader. A deletion notification message including information to the effect and information to update to delete the association between the user and the project from the project database is transmitted (step S65).

  As a result of the determination, if the sum of the participation indices is not less than or equal to the predetermined threshold (step S64: No), the sum of the participation indices for the predetermined period is calculated for the project selected in step S61 with reference to the project database. If there is a user who has not yet calculated the total sum of participation indexes for a predetermined period (step S66: Yes), the process proceeds to step S62. For the project selected in S61, the processing from step S62 to step S66 is repeated until the calculation of the sum of participation indexes for a predetermined period is completed for all users belonging to the project.

  On the other hand, for the project selected in step S61, when the calculation of the sum of participation indexes for a predetermined period is completed for all users belonging to the project (step S66: No), the user is referred to the project database. It is determined whether or not there is a project for which the calculation of the participation index has not been completed (step S67), and the calculation of the sum of the participation indices for the predetermined period of time for all the projects registered in the project database has not been completed. In such a case (step S67: Yes), the processing from step S61 to step S67 is repeated until the calculation is completed for all the projects registered in the project database.

  And if calculation is completed about all the projects (step S67: No), a process will be complete | finished.

  In step S65 described above, after the deletion notification message is transmitted, the correspondence between the user and the project related to the deletion notification of the project database is deleted from the management user who has received the message via the terminal device 2 or other devices such as a PC. When an instruction to permit (update is permitted) has been issued, the association is deleted and the project database is updated.

  As described above, according to another embodiment 2, the sum of participation indexes indicating the degree of participation in the project for each user is calculated for a predetermined period, and the sum of the participation indexes is compared with a predetermined threshold value. Since the deletion notification message is sent to the management user when it is below the predetermined threshold value, the management user can easily grasp the information of the user with a low participation degree and Since it is configured to delete the association with the corresponding project in the project database, the project database can be kept up-to-date, and the effect of preventing erroneous transmission of electronic files to users who do not belong to the project is improved. be able to. In particular, by calculating a participation index that indicates the degree of participation of each user in each project, the user may participate in many projects alone, or the user may frequently participate in and withdraw from the project. In addition, it is possible to easily grasp and manage the degree of participation of each user in each project.

  In the second embodiment described above, the project database is updated only when an instruction to permit the update of the project database is given from an administrative user. As a technique, after the deletion notification message is sent, if there is no instruction to stop the deletion (update stop) from the management user for a certain period of time, it may be configured to update, or as another technique, Users who have registered their activities in the event database and have not participated in the activities related to the event will immediately leave the project (regardless of the configuration in which the sum of the participation indices is compared with the predetermined threshold). (Deleted). In this case, the control unit 11 may be configured to confirm the participation state of each user belonging to the corresponding project at the stage when the date and time when the more important event is held has elapsed.

  Further, when the user transmits an electronic file, it is determined whether or not the sum of participation indexes in a predetermined period of the transmission destination user is equal to or less than a predetermined threshold by referring to the history database. In this case, it may be configured to transmit warning presentation data that warns the user who desires transmission of erroneous transmission. In this case, before the electronic file transmission process in step S10 of the “electronic file transmission process” by the server device 1 described above, the control unit 11 extracts and acquires the project ID assigned to the <1> electronic file. <2> Obtain the user ID of the destination user based on the information specifying the destination obtained in step S4, and record the history based on the project ID and user ID obtained in <3> <1> and <2>. It may be determined by referring to the database and comparing the sum of the participation indexes of the transmission destination users with a predetermined threshold. According to such a configuration, it is possible to reliably prevent the electronic file from being transmitted to a user who is likely to have left the project whose sum of participation indexes is equal to or less than a predetermined threshold. In particular, the sum of participation indexes can be confirmed by referring to the history database without waiting for the execution of “project database update management processing” performed periodically by the server device 1.
