Information processing apparatus, information processing system, and non-transitory computer readable medium

A non-transitory computer readable medium storing a program causing a computer to execute a process for processing information, the process comprising:

• displaying messages received from a plurality of other information processing apparatuses, and transmission messages from an information processing apparatus, in a display region in a time sequence;
• receiving a transmission message responsive to a received message displayed on the display, and a transmission instruction of the transmission message;
• if a second received message different from a first received message from a link destination to which the transmission message is directed is displayed in the display region before the transmission instruction of the transmission message is received, controlling the display such that the transmission message indicating an association with the first received message is displayed on the display region;
• if a plurality of transmission messages are transmitted within a predetermined period of time, determining that the plurality of transmission messages satisfy a first predetermined condition that they are regarded as a group;
• and
• if the first predetermined condition is satisfied, determining that each of the plurality of transmission messages included in the group is a response to the first received message, and controlling the display such that the first received message is displayed in association with the transmission messages regarded as the group on the display region.

An information processing apparatus comprising:

• a display configured to display messages received from a plurality of other information processing apparatuses, and transmission messages from the information processing apparatus, in a display region in a time sequence;
• a receiving unit configured to receive a transmission message responsive to a received message displayed on the display, a select command to select the transmission message, and a transmission instruction of the transmission message;
• and
• a controller configured to:
• if a second received message different from a first received message from a link destination to which the transmission message is directed is displayed in the display region before the receiving unit receives the transmission instruction of the transmission message, control the display such that an association between the first received message and the transmission message is displayed on the display region, the association being represented by displaying the first received message if the transmission message is selected;
• if a plurality of transmission messages are transmitted within a predetermined period of time, determine that the plurality of transmission messages satisfy a first predetermined condition that they are regarded as a group;
• and
• if the first predetermined condition is satisfied, determining that each of the plurality of transmission messages included in the group is a response to the first received message, and control the display such that the first received message is displayed in association with the transmission messages regarded as the group on the display region.
