An IR thesaurus does not provide the following :

  • A.Broader/Narrower terms
  • B.Equivalent terms
  • C.Related terms
  • D.Meanings of terms

Answer: D

An IR thesaurus does not provide the meanings of terms.

An information retrieval thesaurus is a controlled vocabulary for indexing and searching. What it records for each term is its relationships: broader and narrower terms (hierarchy), equivalent terms (use and used-for references for synonyms) and related terms. At most it adds a scope note to fix how a term is to be used.

It is not a dictionary, so it does not give definitions or meanings. The three other options are the very relationships a thesaurus exists to display.
