About Taxonomies & Controlled Vocabularies

A controlled vocabulary for a project might actually include multiple authority files for different kinds of terms. Controlled vocabularies are used to ensure consistent indexing, particularly when indexing multiple documents, periodical articles, web pages or sites, etc. They may also be used when indexing a single work, such as a encyclopedia, by multiple indexers. Controlled vocabularies do not necessarily have any structure or relationships between terms within the list. Online controlled vocabularies often have synonyms or See references to point the user or search engine from an incorrect (unpreferred) variant to the equivalent preferred term in the controlled vocabulary.

Controlled vocabularies are the broadest category, which includes thesauri and taxonomies. Taxonomies Thesauri Ontologies. DHLUNBISThesaurus.

searchFAST

This new interface simplifies the process of heading selection, in an easy to use one-page design. FAST subject headings were developed by adapting the Library of Congress Subject Headings (LCSH) with a simplified syntax, retaining the very rich vocabulary of LCSH while making the schema easier to understand, control, apply, and use. The new interface design combines search box, brief results list, and full view of a selected record on a single page. Several indexes and the ability to restrict the result to a desired FAST facet increase searching accuracy. The default result ranking is by usage, giving the most likely candidate heading near the top of the result, although alphabetic and facet order options are easily available. NEW FEATURE: searchFAST can now limit your search to the record status. Example: "gettysburg status:xs" retrieves two obsolete headings.
