descriptor
(n.) = descriptor ; descriptor term ; epithet ; index term ; subject term ; catchword ; subject description ; index word.
Ex: Descriptors are terms which are acceptable for use in indexes to describe concepts.
Ex: The MEDLINE thesaurus, available online and ondisc, provides a complete list of all descriptor terms (i.e. the controlled vocabulary used in the subject indexing of all Medline citations).
Ex: He also allows Christian names accompanied by an epithet (Aunt Jane, for example) to be used as headings for the main entry.
Ex: This access is achieved by organising the tools so that a user may search under a specific access point or heading or index term, for example, subject term, author, name, title, date.
Ex: In alphabetical indexing languages, such as are embodied in thesauri and subject headings lists, subject terms are the alphabetical names of the subjects.
Ex: These summaries are a valuable aid to classification by ensuring that the classifier finds the correct discipline rather than a catchword in the index.
Ex: During searching the index user is expected to formulate headings in the same way, and hopefully to match his subject description with the indexer's description.
Ex: The Permuterm index (as featured in Science, and Social Sciences Citation Indexes) is similar to a Double-KWIC index in that it provides for simple coordination of index words.
