Thesauri usage in information retrieval systems: example of LISTA and ERIC database thesaurus

This paper offers some toughts on the usage of thesaurus in information retrieval with special reference to information retrieval systems like databases. A thesaurus is an example of controlled vocabulary and an important aid in subject analysis. Controlled vocabularies are used to describe the subject within knowledge organization systems, where the sole purpose of a vocabulary control is to achieve a consistency of subject description and facilitation of information retrieval. We survey some approaches to this question in literature and give two examples of usage of thesaurus in the following databases: the Thesaurus of ERIC Descriptors and LISTA thesaurus. These thesauri are described along with their functions and display in database.
