- In this passage, each of the underlined phrases is used by the speaker to denote one person named [Jane Doe]. We refer to this use of linguistic expression like her or Jane Doe to denote an entity or individual as reference*. In the next few sections of this chapter we study the problem of reference resolution. Reference resolution is the task of determining what entities are referred to by which linguistic expression.
- A natural language express used to perform reference is called a referring expression, and the entity that is referred to is called the referent.
- To referring expressions that are used to refer to the same entity are said to corefer. … There is also a term for a referring expression that license the use of anther, in the way that the mention of John allows John to be subsequently referred to as he. We call John the antecedent of he. Reference to an entity that has been previously introduce into the discourse is called a anaphora, and the referring expression use is to be anaphoric.
- 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 that 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.
