What is Coreference Resolution ?

  • A.Anaphora Resolution
  • B.Given a sentence or larger chunk of text determine which words (mentions) refer to the same objects (entities)
  • C.Solution obtained through coreference
  • D.Solution of a previous solved problem

Answer: B

Coreference resolution is: given a sentence or larger chunk of text, determine which words (mentions) refer to the same objects (entities).

For example, in 'Asha met Ravi because she needed his help', coreference resolution links 'she' to Asha and 'his' to Ravi. The mentions can be names, noun phrases or pronouns, possibly far apart in the text.

Anaphora resolution, linking a pronoun or other anaphor to its antecedent, is one part of the task, not its definition. The other two options describe solutions to problems, which has nothing to do with the term.
