There are two conceivable readings for (1). Either (a) it refers to the party or (b) Peter only disliked the food. Discourse grammars like Segmented Discourse Representation Theory (SDRT) offer an explanation for this phenomenon. SDRT an extension ofDRT (Kamp and Reyle, 1993) describes a complex propositional structure of Discourse Representation Structures (DRSs) connected via discourse relati...

To understand a discourse the reader needs to recover the relations between the discourse elements as intended by the writer Writers can and very often do help the reader along by providing explicit lexical signals of the intended discourse relations through the use of lexicalised discourse markers In this paper we present a novel approach for generating texts containing multiple embedded rheto...

To understand a discourse, the reader needs to recover the relations between the discourse elements as intended by the writer. Writers can, and very often do, help the reader along by providing explicit lexical signals of the intended discourse relations through the use of lexicalised discourse markers. In this paper we present a novel approach for generating texts containing multiple, embedded...

Most document structures define layout structures which implicitly define semantic relationships between content elements. While document structures for text are well established (books, reports, papers etc.), models for time based documents such as multimedia and hypermedia are relatively new and lack established document structures. Traditional document description languages convey domain-dep...

This paper reports on the development of a computational theory of discourse The theory is based on the thesis that discourse structure is a composite of three structures the structure of the sequence of utterances, the structure of intentions conveyed, and the attentional state. The distinction among these components is essential to provide adequate explanations of such discourse phenomena as ...

In the last decade, members of the computational linguistics community have adopted a perspective on discourse based primarily on either Rhetorical Structure Theory or Grosz and Sidner’s Theory. However, only recently, researchers have started to investigate the relationship between the two perspectives. In this paper, we use Moser and Moore’s (1996) work as a departure point for extending Marc...

We study the relationship between the structure of" discourse and a set of summarization heuristics that are employed by current systems. A tight coupling of the two enables us to learn genre-specific combinations of heuristics that can be used for disambiguation during discourse parsing. The same coupling enables us to construct discourse structures that yield summaries that contain textual un...

A well modeled discourse is the fundamental work of building a dialogue system within a problem domain. The detail of the modeling process could be different from domain to domain. Many researchers have identified different dimensions to model the discourse structures in their own domains. Nevertheless, like most of the software engineering issues, even though the detail process could be domain...

The Right Frontier Constraint (RFC), as a constraint on the attachment of new constituents to an existing discourse structure, has important implications for the interpretation of anaphoric elements in discourse and for Machine Learning (ML) approaches to learning discourse structures. In this paper we provide strong empirical support for SDRT’s version of RFC. The analysis of about 100 doubly ...
