We present the first corpus of texts annotated with two alternative approaches to discourse structure, Rhetorical Structure Theory (Mann and Thompson, 1988) and Segmented Discourse Representation Theory (Asher and Lascarides, 2003). 112 short argumentative texts have been analyzed according to these two theories. Furthermore, in previous work, the same texts have already been annotated for thei...

Rhetorical Structure Theory (RST) (Mann and Thompson 1987), argues that in most coherent discourse, consecutive discourse elements are related by a small set of rhetorical relations. Moreover, RST suggests that the information conveyed in a discourse over and above what is conveyed in its component clauses can be der ived from the rhetorical relation-based structure of the discourse. A large nu...

The term discourse structure is used to denote any structure of a text above that of the sentence. Trees have often been posited as a good abstraction when discourse is taken to have a hierarchical structure (Mann and Thompson 1987; Webber et al. 2003; Marcu 2000; Egg and Redeker 2008). Nevertheless, periodically researchers have commented on the need to depart from the strict singleparent hier...

critical pedagogy (cp), as a poststructuralist educational movement, challenges the asymmetrical, power-over nature of classroom discourse and seeks to accommodate multivocality in the classroom and in the society. this study probed the discourse architecture of efl classrooms in iran. specifically, it aimed to explore to what extent iranian efl classrooms have stepped away from the teacher-dom...

Discourse structure is the hidden link between surface features and document-level properties, such as sentiment polarity. We show that the discourse analyses produced by Rhetorical Structure Theory (RST) parsers can improve document-level sentiment analysis, via composition of local information up the discourse tree. First, we show that reweighting discourse units according to their position i...

Rhetorical structure analysis (RSA) explores discourse relations among elementary discourse units (EDUs) in a text. It is very useful in many text processing tasks employing relationships among EDUs such as text understanding, summarization, and question-answering. Thai language with its distinctive linguistic characteristics requires a unique technique. This article proposes an approach for Th...

This paper presents an automated empirical evaluation of the relationship between clausal structure and pronominal reference. Past work has theorized that incorporating discourse structure can constrain the search space in the resolution of pronouns since discourse segments, and thus potential antecedents, can be made inaccessible as the discourse progresses and the focus changes. However, very...

This paper tries to bring closer two theories of human communication: Commitment stores and dialogue games Hamblin (Hamblin, 1970) introduced the notion of commitments stores whereby dialogue participants can keep track of (public) commitments that arise during the interaction. He also pointed out the rule-governed nature of dialogues, and tried to exhibit set of normative rules (dialogue games...
