Information processing apparatus and non-transitory computer readable medium for determination of message and member suitability for tasks

1. A system comprising:

a communication system providing a communication service used by a plurality of users to send and receive messages via a network;

a user terminal device; and

an information processing apparatus including a processor programmed to

acquire a message sent by the user terminal device for a task from the communication system, the user terminal device being with one of the plurality of users using the communication service, and

transmit, to the user terminal device, information for displaying a warning screen to inform the user that the message is unsuitable if the message acquired is unsuitable for the task, wherein:

the warning screen further displays an option for the user to cancel posting of the message for the task, and

the communication system deletes the message when the user cancels posting of the message for the task.

2. The information processing apparatus according to claim 1 , wherein the processor determines that the message is unsuitable from a reaction of another user to the message.

3. The information processing apparatus according to claim 2 , wherein the processor determines that the message is unsuitable if at least one of a read rate and a reply rate satisfies an unsuitability condition.

4. The information processing apparatus according to claim 1 , wherein, if a time elapsed after the message has been sent for the task is shorter than or equal to a predetermined time, the processor determines that the message is not unsuitable.

5. The information processing apparatus according to claim 2 , wherein, if a time elapsed after the message has been sent for the task is shorter than or equal to a predetermined time, the processor determines that the message is not unsuitable.

6. The information processing apparatus according to claim 3 , wherein, if a time elapsed after the message has been sent for the task is shorter than or equal to a predetermined time, the processor determines that the message is not unsuitable.

7. The information processing apparatus according to claim 1 , wherein, if the message indicates that a reply is not required, the processor determines that the message is not unsuitable.

8. The information processing apparatus according to claim 2 , wherein, if the message indicates that a reply is not required, the processor determines that the message is not unsuitable.

9. The information processing apparatus according to claim 3 , wherein, if the message indicates that a reply is not required, the processor determines that the message is not unsuitable.

10. The information processing apparatus according to claim 1 , wherein the processor determines whether the message is unsuitable by using information obtained from an information system different from the communication system.

11. The information processing apparatus according to claim 10 , wherein:

the information system is a theme management system that manages information by theme, and the task is associated with a theme managed by the theme management system; and

if the message is related to a theme different from the theme associated with the task, the processor determines that the message is unsuitable.

12. The information processing apparatus according to claim 1 , wherein, upon receiving a request to make a change in members of the task, if an attribute of a member to be changed is different from an attribute of an existing member of the task, the processor performs control to inform the member to be changed that the member is unsuitable.

13. The information processing apparatus according to claim 2 , wherein, upon receiving a request to make a change in members of the task, if an attribute of a member to be changed is different from an attribute of an existing member of the task, the processor performs control to inform the member to be changed that the member is unsuitable.

14. The information processing apparatus according to claim 4 , wherein, upon receiving a request to make a change in members of the task, if an attribute of a member to be changed is different from an attribute of an existing member of the task, the processor performs control to inform the member to be changed that the member is unsuitable.

15. The information processing apparatus according to claim 12 , wherein the attribute includes at least one of an affiliation, a skill set representing a variety of specific skills, and a professional background concerning the member.

16. The information processing apparatus according to claim 1 , wherein the processor determines whether the message is unsuitable by using evaluation information concerning an evaluation of the message.

17. The information processing apparatus according to claim 2 , wherein the processor determines whether the message is unsuitable by using evaluation information concerning an evaluation of the message.

18. The information processing apparatus according to claim 4 , wherein the processor determines whether the message is unsuitable by using evaluation information concerning an evaluation of the message.

19. The information processing apparatus according to claim 16 , wherein, if the evaluation of the message indicated by the evaluation information satisfies an evaluation condition representing that the message is unsuitable, the processor determines that the message is unsuitable.

20. A non-transitory computer readable medium storing a program causing a processor to execute a process, the process comprising:

acquiring a message sent by a user terminal device for a task from a communication system, the communication system providing a communication service used by a plurality of users to send and receive messages via a network, the user terminal device being with one of the plurality of users using the communication service; and

transmitting, to the user terminal device, information for displaying a warning screen to inform the user that the message is unsuitable if the message acquired is unsuitable for the task, wherein:

the warning screen further displays an option for the user to cancel posting of the message for the task, and

the communication system deletes the message when the user cancels posting of the message for the task.
