The entire idea of using a controlled vocabulary, a.k.a. thesaurus, a.k.a. ontology, a.k.a. taxonomy, a.k.a. authority file, a.k.a. a pick list, a.k.a. attribute table –is to standardize the nomenclature an organization uses to tag, keyword, add descriptors, controlled vocabulary, subject heading, content tags, semantic indexing, etc., to their content so it can be found, searched, retrieved,… well, you get the idea.
