Segmented Discourse Representation Theory (SDRT) [2, 7] provides a dynamic semantics for discourse that exploits a rich notion of discourse structure. According to SDRT, a text is segmented into constituents related to each other by means of rhetorical relations; the resulting structure, known as a segmented discourse representation structure or SDRS has various semantic effects. This theory ha...

This paper is about the flow of inference between communicative intentions, discourse structure and the domain during discourse processing. We augment a theory of discourse interpretation with a theory of distinct mental attitudes and reasoning about them, in order to provide an account of how the attitudes interact with reasoning about discourse structure. INTRODUCTION The flow of inference be...

Research in discourse processing has identi ed two representational requirements for discourse planning systems. First, discourse plans must adequately represent the intentional structure of the utterances they produce in order to enable a computational discourse agent to respond e ectively to communicative failures [15]. Second, discourse plans must represent the informational structure of utt...

The present contribution represents the first step in comparing the nature of syntactico-semantic relations present in the sentence structure to their equivalents in the discourse structure. The study is carried out on the basis of a Czech manually annotated material collected in the Prague Dependency Treebank (PDT). According to the semantic analysis of the underlying syntactic structure of a ...

This article aims to present a set of discourse structure relations that are easy to code and to develop criteria for an appropriate data structure for representing these relations. Discourse structure here refers to informational relations that hold between sentences in a discourse. The set of discourse relations introduced here is based on Hobbs (1985). We present a method for annotating disc...

The paper presents a method of building the discourse structure of a discourse by combining indications on local structure given by cue-phrases with indications on global structure given by references found in the text. Then the discourse structure is used to obtain focused summaries.

This paper presents a study in sentiment analysis which exploits information of the relational discourse structure in a Basque corpus consisting of literature reviews. The QWN-PPV method was employed to label all the texts at element level and the Rhetorical Structure Theory (RST) was used to extract discourse structure information. The preliminary results show that discourse structure is effec...

Attentional State Theory and Rhetorical Structure Theory are two predominant theories of discourse parsing. Combining these two approaches, in this paper, we describe a novel approach for discourse parsing. The resulting discourse tree structure retains following properties: structure of purpose from Attentional State Theory and relations between sentences from Rhetorical Structure Theory. We d...

1. ABSTRACT We present results of a study of the relationship between intonational features including pitch range, timing, and amplitude and aspects of discourse structure defined in terms of Grosz and Sidner's (1986) model of discourse. We compare structural labelings of AP news text with prosodic/acoustic features examined from recordings of the same text read by a professional newscaster. We...
