| Abstract | The Thesaurus, in information retrieval, represents one of the cardinal points of a system, since neither indexing quality nor retrieval strategy sophistication are able to remedy deficiencies of the Thesaurus used. In principle, the Thesaurus is a collection of concepts which are more or less important for the subject field of the document collection. Usually the mere list of the terms representing the concepts is enriched by two factors: — lists of synonyms of which one only is considered to be valid (this list also revolves the problem of ambiguities of terms through replacement by univocal terms); —classification schemes which may be both hierarchic and associative and may present different degrees of sophistication. Classification of terms, in information retrieval has the primary task of permitting search on a different level of specificity from that of the documents. |
