Abstract

A collaborative information processing system is formed of a plurality of terminal units interconnected through a network. Each terminal unit includes a microprocessor provided with a control program for controlling the execution of various application programs and the communication with other terminal units, input/output devices such as a display unit with a display screen and keyboard, and a telephone set. A plurality of users join in a conference or such a group work to create materials by making reference to a material which is displayed equally on the screen of each terminal unit and making conversation through the telephone set under control of the control program. Records of group work information including the outline of the group work, names of participants, and names of materials and data created or referenced during the group work or conference are stored automatically in a database so that the records can readily be retrieved in the future.

3. The collaboratively processed information storing method according to claim 2, wherein said group work identification data further comprises names of participants who engage in the group work.

4. The collaboratively processed information storing method according to claim 2, wherein said data of group work name is data of a name which is given to the window, in which said group work is held, created on a screen of said display units.

5. The collaboratively processed information storing method according to claim 2, wherein said group work identification data further comprises information for identifying a work which is specified arbitrarily by a user.

6. The collaboratively processed information storing method according to claim 1, wherein said group work matter data comprises data indicative of a name of a material which is used in said group work.

7. The collaboratively processed information storing method according to claim 6, wherein said group work matter data further comprises data indicative of a time when said material is referenced.

8. The collaboratively processed information storing method according to claim 6, wherein said group work matter data further comprises information for distinguishing whether said material is one which is sent to an other terminal unit or one which is received from the other terminal unit.

9. A method of storing group work information referenced in a group work carried out through a computer network system in which a plurality of terminal units are interconnected through a network, each terminal unit comprising a display unit having a display screen, an input unit, a processor provided with a control program for implementing communication among said terminal units so that a plurality of terminal units operate in unison for information processing in response to input operation on said input units, and a telephone set, and a plurality of participants in remote places engage in a group work by using group work information displayed on the display screens and voices through said telephone sets, said method comprising steps of:

forming, on the display screen, a group work environment carrying out the group work;

creating work identification data for identifying the group work environment formed on the display screen;

selectively creating work matter data indicative of index information for retrieving a material referenced in the group work, in response to user operations taken in the group work environment; and

storing said work matter data in association with said work identification data in a data file for future information retrieval of said material.

10. The group work information storing method according to claim 9, wherein said work identification data comprises data of a name which is given to the group work environment formed on the display screen and data of a date or a date and time when the group work is held.

11. The group work information storing method according to claim 10, wherein said work identification data further comprises data of the names of participants who engage in the group work environment.

12. The group work information storing method according to claim 9, wherein said work identification data comprises auxiliary information defined by a user.

13.
