In this paper we report on several issues arising out of a first attempt to annotate task-oriented spoken dialog for rhetorical structure using Rhetorical Structure Theory. We discuss an annotation scheme we are developing to resolve the difficulties we have encountered.

This paper describes a study of the levels at which different rhetorical relations occur in rhetorical structure trees. In a previous empirical study (Williams and Reiter, 2003) of the RST-DT (Rhetorical Structure Theory Discourse Treebank) Corpus (Carlson et al., 2003), we noticed that certain rhetorical relations tended to occur more frequently at higher levels in a rhetorical structure tree,...

Explaining why the same passage may have different rhetorical structures when conveyed in different languages remains an open question. Starting from a trilingual translation corpus, this paper aims to provide a new qualitative method for the comparison of rhetorical structures in different languages and to specify why translated texts may differ in their rhetorical structures. To achieve these...

This paper addresses discourse structure from the perspective of understanding. It would perhaps help us understand the na,ture of discourse relatiolls il" we better understood what units of a text. can be related to one a.nother. In Olle ma.jor theory of discourse structure, Rhetorical Structure Theory (Mann &: Thompson 1988; Imrea.l'ter simply RS'T), the smallest possible linguistic units tha...

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...

RASTA (Rhetorical Structure Theory Analyzer), a system for automatic discourse analysis, reliably, identifies rhetorical relations present m written discourse by examining information available in syntactic and logical form analyses. Since there is a many-to-many relationship between rhetorical relations and elements of linguistic form, RASTA identifies relations by the convergence of a number ...

This article aims to analyze how agreement regarding the central unit (macrostructure) influences agreement when establishing rhetorical relations (microstructure). To do so, the authors conducted an empirical study of abstracts from research articles in three domains (medicine, terminology, and science) in the framework of Rhetorical Structure Theory (RST). The results help to establish a new ...

This paper introduces an approach to generate video clips starting from an annotated commentary. The novelty of the approach lies in the use of rhetorical structure of the accompanying audio commentary in planning the video. The basic notions of cinematography are briefly introduced together with the Rhetorical Relation Theory to model the structure of a discourse. Then, the architecture of a v...
