The authors had discussed an automatic categorization of documents of cause of collision accidents from the Report of Judgement on Marine Accident Inquiry Agency by term weighting. In this paper, a method of categorization using a thesaurus is proposed. Term weights are not determined as an individual word, but determined as synonyms for a reason that large number synonyms in each category make a feature of each category. The synonyms are classified by superordinate/subordinate, part/whole relation. The results obtained in this research are as follows. (1) The thesaurus consists of about 280 words which is available for documents categorization is constructed. (2) After repetition of editing the thesaurus and experimental tests, the thesaurus of fewer words obtained high accuracy of categorization. (3) The accuracy of a right answer is about 75% at the maximum.
