- QUOTE: We are now ready to two referent resolution tasks: coreference resolution and pronominal anaphora resolution. Coreference resolution is the task of finding referring expression in a text that refer to the same entity, that is, finiding expression that corefer. We call the set of coreferring expressions a coreference chain.
Coreference resolution the requires finding all referring expression in a discourse and group them into coreference chains. By contrast, pronomial anaphora resolution is the task of finding the antecedent for a single pronoun.
