Controlled Vocabularies and Thesauri Flashcards

What is the primary purpose of a controlled vocabulary in an information system?

Answer: To ensure consistent terminology is used to describe and retrieve content

Controlled vocabularies standardize terminology so content can be described and retrieved consistently across an information system.

In thesaurus notation, what does 'BT' stand for?

Answer: Broader Term

BT (Broader Term) indicates a hierarchically superior concept relative to the entry term in a thesaurus.

What is a 'USE' reference in a thesaurus?

Answer: A direction from a non-preferred term to its preferred equivalent

USE references direct users from a non-preferred (entry) term to the authorized preferred term for consistent indexing.

SKOS (Simple Knowledge Organization System) is a W3C standard primarily designed for:

Answer: Representing thesauri and controlled vocabularies on the Semantic Web

SKOS provides a data model for expressing the structure and content of concept schemes such as thesauri as linked data on the Web.

Which type of relationship in a thesaurus connects terms that are related but share neither a hierarchical nor an equivalence relationship?

Answer: RT (Related Term)

RT (Related Term) indicates an associative relationship between concepts that are cognitively linked but not hierarchically organized.

An authority file in controlled vocabulary management is best described as:

Answer: A list of approved term forms along with their variants and cross-references

Authority files document the authorized forms of names and terms, along with variant forms and cross-references, ensuring consistent application.

A synonym ring in information retrieval is best described as:

Answer: A set of equivalent terms treated as interchangeable during searching

A synonym ring groups semantically equivalent terms so a search for any one term automatically retrieves results indexed under all other members.
