  • Miscellaneous
    • "Anaphora resolution is the process of interpreting the link between the anaphor and the previous reference, its antecedent. It is especially interesting because it frequently involves interpretation across a sentence boundary."

    • 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, finding expression that corefer. We call the set of coreferring expressions a coreference chain.
    • Coreference resolution 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.




  • (Morton, 2000)
    • found that ~98.7% of Anaphor Antecedents were within two Sentences.

    • QUOTE: "Anaphora is cohesion (presupposition) which points back to some previous item. The "pointing back" (reference) is called an anaphor and the entity to which it refers is its antecedent. The process of determining the antecedent of an anaphor is called anaphora resolution."
