Anaphora and Discourse Structure
We argue in this paper that many common adverbial phrases generally taken to signal a discourse relation between syntactically connected units within discourse structure, instead work anaphorically to contribute relational meaning, with only indirect dependence on discourse structure. This allows a simpler discourse structure to provide scaffolding for compositional semantics, and reveals multi...
متن کاملCentering, Anaphora Resolution, and Discourse Structure
Centering was formulated as a model of the relationship between attentional state, the form of referring expressions, and the coherence of an utterance within a discourse segment (Grosz, Joshi and Weinstein, 1986; Grosz, Joshi and Weinstein, 1995). In this chapter, I argue that the restriction of centering to operating within a discourse segment should be abandoned in order to integrate centeri...
متن کاملLogical Structure And Discourse Anaphora Resolution
Working within the Dynamic "Quantifier Logic (DQL) framework (van den Berg 1992, 1996a,b), we claim in this paper that in every language the translation into a logical language will be such that the preference ordering of possible discourse referents for an anaphor in a sentence can be explained in terms of the scopal order of the exp _re~Lslons in the antecedent that introduce the discourse re...
متن کاملDiscourse Structure and Anaphora : an Empirical Study
One of the main motivations for studying discourse structure is its effect on the search for the antecedents of anaphoric expressions. We tested the predictions in this regard of theories assuming that the structure of a discourse depends on its intentional structure, such as Grosz and Sidner's theory. We used a corpus of tutorial dialogues independently annotated according to Relational Discou...
متن کاملDiscourse Anaphora
This paper reports on a model that serves anaphora resolution. A distinction will be made between possible antecedents and preferred an.tecedents. The set of linguistically possible can-didates will be detined in terms of compatibili ty and recency. Preferred antecedents are a subset of the possible antecedents, selected by the application of extralinguistic knowledge. Motivation for the partic...
