An information retrieval thesaurus is a familiar object: it consists of a set of more or less controlled terms functioning as conceptual labels for sets of natural language entry words, with some indication of relations between terms in the form of references from terms to other BT's, NT's or RT's. Such an indexing language differs from a set of natural language keywords in involving vocabulary normalization; from a list of subject headings in being designed for post‐co‐ordination; and from a classification in having a limited structure.
