THESAURUS DATA MANAGING METHOD

PROBLEM TO BE SOLVED: To efficiently refer to data for large scale data not to be updated by artificially generating updated data without really updating data corresponding to the update request of a user. SOLUTION: A client A104 displays one part of data structure of a shared thesaurus 100 on the screen of a display device 103 while scrolling it, segments the partial data structure corresponding to the operation of a user 101 and stores the operation at that time in a temporary storage device 106. Next, concerning the partial data structure, rearrangement processing is performed based on the operation of the user 101 and that rearrangement operation is stored in the temporary storage device 106. Afterwards, sequential display updating processing is performed from the stored information and correcting operation is finished. Next, corrected information generating processing is performed while using the stored information and generated corrected information is stored in a corrected information DB 108. Then, based on the corrected information and the shared thesaurus 100, thesauruses by viewpoints are reproduced and synthetically displayed.
