其他摘要：We had requests such as enlargement of terms to be covered in the Thesaurus, description of term history and so on through the questionnaires to JOIS users specifically conducted on the occasion of preparing 1987 edition of JICST Thesaurus. Based on them the following measures were taken : addition of new terms by referring natural words stored in JICST database, addition of some Chinese characters used for it, addition of priority data among synonyms and others, and improvement of term relations by using English translated Japanese keywords. How the Thesaurus was edited, and measures against problems associated with editing are described. Necessity of the routine maintenance and subjects to be solved from now on are also described.
