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]

The notion that a text is coherent in virtue of the `relations' which hold between the elements of that text has become fairly common currency, both in the study of discourse coherence and in the eld of text generation. The set of relations proposed in Rhetorical Structure Theory (Mann and Thompson [14]) has had particular in uence in both of these elds. But the widespread adoption of `relation...

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...

actions are decomposed until primitive communicative actions (executable as speech acts) are reached. In performing this task, the text planner relies on the set of explanation strategies that specify possible decompositions for each communicative action and the constraints dictating when they may be applied. These constraints are checked against the solution graph and when they are satisfied t...

At present, discourse parsing is an important research topic. Rhetorical Structure Theory (RST) is one of the most popular approaches in this field. In general, discourse parsing includes three stages: discourse segmentation, discourse relations detection and building up rhetorical trees. Different strategies are used when developing discourse parsers. One of the strategies to detect discourse ...

Natural language provides an extensive set of lexical and grammatical forms for expressing concepts, a set from which writers choose the particular form that they feel will produce the most effective expression given the communicative context. An important task of the text generation researcher is to specify both the range of these forms and the contexts in which they are used. This paper addre...

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...
