Controlled Vocabulary makes database searching more efficient by utilizing academically accepted terms to describe key
concepts. It is different
than the use of Natural Language, which is how typical search engines, such as Google, are indexed.
Natural Language can also be thought of as everyday language.
Stop Words are ignored in Controlled Vocabulary. Stop Words are words,
such as the, a, an, this, and that.
Controlled Vocabulary can also be thought of as indexed terms or keywords.
Controlled Vocabulary is used in organizing Subject Headings for online database records and online catalogs (OPAC online public access catalog) in your local public or academic library.
