Special Edition: 1981 JICST Classification Table•Thesaurus : JICST Thesaurus on Science and Technology-Terms of Organic Compounds-

Abstract

On the occasion of publishing 1981 edition of JICST Thesaurus on Science & Technology this paper describes the term organization of organic compounds included in this Thesaurus, the indexing method of the organic compounds and the retrieval function by link which has been initiated. Originally there is no indexing method other than combining descriptors in order to represent millions of organic compounds by use of a thesaurus. The huge amount of the combination rules makes indexing and retrieving considerably difficult. This burden is inevitable to organic compounds so that not only JICST Thesaurus but also other thesauri or methods such as free terms cause the same trouble for their indexing and retrieving. JICST method of indexing organic compounds is explained along with a lot of examples.
