Thesaurus

A thesaurus is a semantic tool used for information retrieval, query expansion and indexing, among other purposes. It is basically a selection of the basic vocabulary in a domain supplemented with information about synonyms, homonyms, generic terms, part/whole terms, “associative terms” and other information (e.g. frequency and history of terms in a given database).
