This paper introduces the first Basque discourse TreeBank annotated with rhetorical relations following Rhetorical Structure Theory. We report the main features of the corpus, such as the annotation criteria, inter-annotator agreement and harmonization procedure. We describe an online search system to check the annotation of discourse relations.

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.

We derive the rhetorical structures of texts by means of two new, surface-form-based algorithms: one that identifies discourse usages of cue phrases and breaks sentences into clauses, and one that produces valid rhetorical structure trees for unrestricted natural language texts. The algorithms use information that was derived from a corpus analysis of cue phrases.

Rhetorical moves are a useful framework for analyzing the hidden rhetorical organization in research papers, in teaching academic writing. We propose a ∗ 國立清華大學資工系 NTHU NLPLAB Email: {cheng, hsiang, joe}@nlplab.cc; [email protected]; [email protected]

Negative Polarity Items (NPIs) are known to be licensed in wh-questions. But not all wh-questions behave alike with respect to NPI licensing. As pointed out in Han and Siegel (1996), while all argument wh-questions with NPIs can have a RHETORICAL QUESTION reading, only a subset of them can have a true wh-question reading. In this paper, we point out that adjunct wh-questions with NPIs cannot ha...

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...

The study of argumentation has undergone periods of decadence alternate with periods of renaissance. Currently, we are witnessing one of the latter, as proved by research flowering in many issues and aspects, both in Philosophy and in Artificial Intelligence. The work presented in this thesis is concerned in particular with “rhetorical argumentation”, which on the other hand has enjoyed conside...
