RASTA (Rhetorical Structure Theory Analyzer), a discourse analysis component within the Microsoft English Grammar, efficiently computes representations of the structure of written discourse using information available in syntactic and logical form analyses. RASTA heuristically scores the rhetorical relations that it hypothesizes, using those scores to guide it in producing more plausible discou...

Scott and Souza have posed the problem of how a rhetorical structure in which proposi tions are linked by rhetorical relations but not yet arranged in a linear order can be realized by a text structure in which propositions are ordered and linked up by appropriate discourse connectives Almost all work on this problem assumes implicitly or explicitly that this map ping is governed by a constrain...

In this paper, we propose a Connectivedriven Dependency Tree (CDT) scheme to represent the discourse rhetorical structure in Chinese language, with elementary discourse units as leaf nodes and connectives as non-leaf nodes, largely motivated by the Penn Discourse Treebank and the Rhetorical Structure Theory. In particular, connectives are employed to directly represent the hierarchy of the tree...

Questions play a prominent role in social interactions, performing rhetorical functions that go beyond that of simple informational exchange. The surface form of a question can signal the intention and background of the person asking it, as well as the nature of their relation with the interlocutor. While the informational nature of questions has been extensively examined in the context of ques...

The IMAGENE project has studied the expression of actions in the context of instructional text generation. The approach employs a rather traditional interpretation of Rhetorical Structure Theory (RST) (Mann and Thompson, 1989), using it both as a descriptive tool and as a constructive tool (Mann and Thompson, 1987). No explicit representation of and reasoning about intentions was employed. In t...

Empirical studies of text coherence often use tree-like structures in the spirit of Rhetorical Structure Theory (RST) as representational device. This paper identifies several sources of ambiguity in RST-inspired trees and argues that such structures are therefore not as explanatory as a text representation should be. As an alternative, an approach toward multi-level annotation (MLA) of texts i...

This paper provides a corpus-based generic characterization of appointment-scheduling dialogues—a type of task-oriented conversation—by concentrating on the rhetorical and thematic choices made by the speakers that produce them. The analytical tools used for this study are Rhetorical Structure Theory (RST), the notion of Theme as defined in Systemic Functional Linguistics, and Thematic Progress...

This study investigates the prosodic realization of organizational features of texts. Twenty read aloud news reports were annotated according to Rhetorical Structure Theory (RST). This theory defines the clustering of elementary units (clauses) into larger segments (hierarchical organization), the relative importance of units (nuclearity) and the rhetorical relations between segments. The proso...
