Abstract : The system described here is as used in the Armed Services Technical Information Agency (ASTIA). ASTIA uses a large thesaurus for classifying and searching technical subject matter which is a combination of terms that encompass all of technology. An attempt is currently underway to break out several artoriented, highly specific microthesauri. This paper describes the procedure used to help reorganize and refine one of these thesauri, the Chemical Thesaurus. (Author)
