Abstract

This paper describes an ongoing project in which the subject headings contained in twelve controlled vocabularies covering multiple disciplines from the humanities to the sciences and including law and education among others are being collapsed into a single vocabulary and reference structure. The design of the database, algorithms created to programmatically link like-concepts, and daily maintenance are detailed. The problems and pitfalls of dealing with multiple vocabularies are noted, as well as the difficulties in relying purely an computer generated algorithms. The application of this megathesaurus to bibliographic records and methodology of retrieval is explained.
