This paper presents a system which intends to resolve anaphora in the framework of the Discourse Representation Theory, arrd using a lexicon-grammar of anaphoric verbs, through the application of selection criteria for assignment of a referent to an anaphora. From a semantic representation of text provided by a DRT system implemented in Prolog, the system uses several criteria of selection of r...

A distribution of anaphoric elements roughly like that found in English occurs in languages around the world: There are certain lexical items that occur only with antecedents which ccommand them and which are located in the same local domain (roughly, clause) as the anaphoric elements. In contrast, other anaphoric elements are unable to take c-commanding antecedents within the local domain. The...

This study investigates the effects of variation in anaphoric form by comparing the processing and interpretation of a null VP-anaphoric phrase (i.e. did too) and an overt VP-anaphoric phrase (e.g. did it too) in contexts where both forms are grammatical. Unification theories predict that in contexts involving a highly accessible antecedent, participants prefer the least informative grammatical...

The computational model in present paper confirms that memory-based accounts are sufficient to account for a high rate of success at first-pass referent retrieval for anaphoric (and non-anaphoric) nouns. Because even definite noun phrases can often be non-anaphoric (e.g., Poesio & Vieira, 1998), an adequate model must account for how a reader makes an explicit or implicit decision about the ana...

The assumption of term-based summarisation method is that the importance of a sentence can be determined by the importance of the words it contains. One drawback of these methods is that they usually consider the words in isolation, ignoring relations such as anaphoric links between them. This paper investigates to what extent the integration of pronominal anaphora resolution into the summarisa...

Anaphora resolution for dialogues is a difficult problem because of the several kinds of complex anaphoric references generally present in dialogic discourses. It is nevertheless a critical first step in the processing of any such discourse. In this paper, we describe a system for anaphora resolution in multi-person dialogues. This system aims to bring together a wide array syntactic, semantic ...

The semantic treatment of anaphora using λ-DRT with Glue which I present combines the strengths of both by assigning to each the task where it arguably fares best: Glue composes meanings and DRT deals with anaphoric resolution. Key to this approach is a simple first-order system for λ-DRT that allows LFG syntactic constraints to be transferred into the dynamic representation language. This para...
