چکیده

In this paper we present a formalization of the centering approach to modeling attentional structure in discourse and use it as the basis for an algorithm to track discourse context and bind pronouns. As described in [GJW86], the process of centering attention on entities in the discourse gives rise to the intersentential transitional states of continuing, retaining and shifting. We propose an extension to these states which handles some additional cases of multiple ambiguous pronouns. The algorithm has been implemented in an HPSG natural language system which serves as the interface to a database query application.

A Corpus Study of Zero Pronouns in Hindi: An Account Based on Centering Transition Preferences

This paper presents a corpus-based investigation of the use of zero pronouns in Hindi. After establishing that the antecedents of these null arguments cannot be recovered syntactically (Rizzi, 1982; Jaeggli & Safir, 1989), I propose an account in terms of "Centering Theory" (Grosz et al., 1995). Given the Hindi-specific centering constraints proposed in Prasad & Strube (2000), I argue that the ...

Intrasentential Centering: A Case Study

One of the necessary extensions to the centering model is a mechanism to handle pronouns with intrasentential antecedents. Existing centering models deal only with discourses consisting of simple sentences. It leaves unclear how to delimit center-updating utterance units and how to process complex utterances consisting of multiple clauses. In this paper, I will explore the extent to which a str...
