The simplest type of referring expressions are pronoun such as he and it. The linguistics and natural language processing communities have developed various models for predicting anaphor referents, such as centering theory, [1] and ideally referring-expression generation would be based on such models. However most NLG systems use much simpler ...

In linguistics, anaphora (/ ə ˈ n æ f ər ə /) is the use of an expression whose interpretation depends upon another expression in context (its antecedent).In a narrower sense, anaphora is the use of an expression that depends specifically upon an antecedent expression and thus is contrasted with cataphora, which is the use of an expression that depends upon a postcedent expression.
Since the phrase "some dog is annoying" is not a referring expression, according to Russell's theory, it need not refer to a mysterious non-existent entity. Furthermore, the law of excluded middle need not be violated (i.e. it remains a law), because "some dog is annoying" comes out true: there is a thing that is both a dog and annoying.
Determining which expressions are coreferences is an important part of analyzing or understanding the meaning, and often requires information from the context, real-world knowledge, such as tendencies of some names to be associated with particular species ("Rover"), kinds of artifacts ("Titanic"), grammatical genders, or other properties.
In Noam Chomsky's government and binding theory in linguistics, an R-expression (short for "referring expression" (the linked article explains the different, broader usage in other theories of linguistics) or "referential expression") is a noun phrase that refers to a specific real or imaginary entity.
An opaque context or referentially opaque context is a linguistic context in which it is not always possible to substitute "co-referential" expressions (expressions referring to the same object) without altering the truth of sentences. [1] The expressions involved are usually grammatically singular terms. So, substitution of co-referential ...
