- 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.

- found that ~97% of Anaphor Antecedents were Intrasentential Anaphora Mentions.

- QUOTE: Anaphora occurs when there is repeated reference to the same entities in a discourse. Anaphora resolution is the process of interpreting the link between the anaphor (i.e., the repeated reference) and its antecedent (i.e., the previous mention of the entity). The process is of interest because it frequently involves interpretation across a sentence boundary. Thus, despite playing a crucial role in discourse comprehension, it falls outside the scope of traditional psycholinguistic accounts of sentence processing. There are two main issues that have driven the psychological research on anaphora resolution. First, there is the issue of how the resolution process relates to more basic sentence comprehension processes, such as syntactic parsing and semantic interpretation. This issue has been addressed principally by investigating the time course of anaphora resolution as compared with other sentence interpretation processes. The second issue concerns the nature of the mental representation of the discourse context that is required to support anaphora resolution. The research indicates that the process depends on access to mental models of discourse containing discourse entities that reflect the people and other things up to that point.

- QUOTE: Anaphora resolution is a complicated problem in Natural Language Processing and has attracted the attention of many researchers. The approaches developed - traditional (from purely syntactic ones to highly semantic and pragmatic ones), alternative (statistic, uncertainty-reasoning etc.) or knowledge-poor, offer only approximate solutions (...)

- In establishing proper referential relations, we found the functional information structure of the utterances to be much more relevant. By this we mean indicators of whether or not a discourse entity in the current utterance refers to another discourse entity already introduced by previous utterances in the discourse. Borrowing terminology from Prince (1981, 1992), an entity that does refer to another discourse entity already introduced is called discourse-old or hearer-old, while an entity that does not refer to another discourse entity is called discourse-new or hearer-new.

- 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."
