<p>A cooperative activity system in which a plurality of computer devices are connected via a network performs an activity by cooperation among the computer devices. A server for recording data is connected to the network and monitors data transferred to the network, creates a keyword conforming to the type of data when the data is transferred and stores the keyword in a file. While data is not being generated, a keyword is created in dependence upon whether a specific time has arrived, the elapsed time of a cooperative activity or the passage of a prescribed period of time from an immediately preceding item of data, and both the keyword and the particular event are stored as a file. As a result, desired cooperative activity data can be read out by performing retrieval based upon the keyword. <IMAGE></p> |
