CIA Controlled Vocabularies and Thesauri 3

Question 1

What primarily distinguishes an ontology from a controlled vocabulary?

Accepted Answer

Ontologies define formal, machine-readable semantic relationships and logical axioms between concepts

Answer

Ontologies are always larger and contain significantly more terms

Answer

Ontologies are restricted to use in scientific and academic research contexts only

Answer

Controlled vocabularies cannot be represented or published in digital environments

Question 2

Which approach is most effective when initially harvesting terms for a new controlled vocabulary?

Accepted Answer

Analyzing domain literature alongside user query logs to identify natural terminology

Answer

Copying an existing thesaurus from a related domain and removing irrelevant terms

Answer

Selecting terms randomly from a representative sample of domain documents

Answer

Relying solely on subject-matter expert suggestions without reviewing user data

Question 3

A scope note (SN) in a thesaurus entry primarily serves to:

Accepted Answer

Clarify the intended meaning and limits of use for a specific term

Answer

List all non-preferred synonyms associated with a preferred term

Answer

Record the historical etymology and origin of a term

Answer

Indicate which broader terms in the hierarchy share the same semantic scope

Question 4

In SKOS, the property 'skos:narrower' is used to express:

Accepted Answer

A hierarchical relationship where the object concept is more specific than the subject

Answer

An equivalence relationship between two concepts in different vocabularies

Answer

An associative relationship between two thematically related concepts

Answer

A note restricting the allowable scope of the subject concept

Question 5

Which vocabulary governance practice best ensures long-term consistency in a controlled vocabulary?

Accepted Answer

Publishing vocabulary updates on a fixed periodic review cycle with documented change management

Answer

Allowing all content editors to propose and add new terms freely without review

Answer

Archiving deprecated terms immediately upon retirement without providing cross-references

Answer

Capping the vocabulary at a fixed number of terms to minimize ongoing maintenance complexity

Question 6

What is the key functional difference between a classification scheme and a thesaurus?

Accepted Answer

A classification scheme assigns systematic notations to organize items, while a thesaurus manages terminology relationships for retrieval

Answer

A thesaurus uses numeric notation while a classification scheme uses alphabetic notation

Answer

Classification schemes are used only for physical items, while thesauri are exclusively for digital content

Answer

A thesaurus always includes broader and narrower terms while a classification scheme never contains hierarchical relationships

Question 7

When integrating a controlled vocabulary with a search engine, query expansion using the vocabulary achieves what primary goal?

Accepted Answer

Retrieving relevant results even when users enter non-preferred or variant terms

Answer

Increasing the length and complexity of user search queries automatically

Answer

Filtering out irrelevant non-preferred terms from the underlying search index

Answer

Prioritizing more recently published documents higher in the search results
