Thesauri and Bibliographic database

Abstract

On the JICST thesaurus, the way of vocabulary control such as representation of terms, the synonym control and setting of the hierarchical relation was described. There is the distinct feature in the semantic relations among thesauri. It is discussed that this feature is the outcome of the distinction in bibliographic detabases to which thesauri are applied. And we mentioned the large-scale electronic dictionary for searching databases which is developing in JST. The purpose of this dictionary is integrated retrieval of variously digital contents that distributed on network.
