Resumo	Thesaurus construction is the systematic building of a controlled vocabulary in which preferred terms are linked by a standardized set of relationships — equivalence, hierarchy, and association — to support consistent indexing and effective retrieval. The definitive practical methodology was set out by Jean Aitchison, Alan Gilchrist, and David Bawden in their manual Thesaurus Construction and Use, and the controlling standard in the United States is ANSI/NISO Z39.19, with ISO 25964 as its international counterpart. A thesaurus collects the terms a domain uses, resolves synonyms and homographs so each concept has one preferred label, and then wires the preferred terms together with USE/UF, BT/NT, and RT relationships plus scope notes. The result is a structured map of a subject's concepts that indexers and searchers share, reducing the mismatch between the words authors, indexers, and users choose.	Knowledge organization system (KOS) design is the principled specification of the artefacts — classification schemes, thesauri, subject heading lists, taxonomies, name and subject authorities, and ontologies — that organize recorded information for retrieval. Elaine Svenonius's The Intellectual Foundation of Information Organization recast this work as the design of bibliographic languages, each with a vocabulary, a semantics, and a syntax, all justified by the user objectives an information system exists to serve: to find, identify, select, and obtain. KOS design begins from those objectives and the entities a domain contains, then specifies controlled vocabulary, fixes the mapping between terms and concepts, defines the syntax for combining terms, and evaluates the result against the objectives and against design principles. Standards such as ANSI/NISO Z39.19 supply the construction rules for the vocabulary layer.
