Explanation

Controlled vocabulary in indexing is called a thesaurus. A thesaurus provides standardized terminology for indexing and retrieval, showing relationships between terms (broader, narrower, related). It ensures consistency in indexing by controlling term selection and helping indexers choose appropriate terms. Unlike a general dictionary, a thesaurus is designed specifically for information organization and retrieval systems.
