Strong generative capacity of RST, SDRT and discourse dependency DAGSs

نویسنده

  • Laurence Danlos
چکیده

The aim of this paper is to compare the discourse structures proposed in RST, SDRT and dependency DAGs which extend the semantic level of MTT for discourses. The key question is the following: do these formalisms allow the representation of all the discourse structures which correspond to felicitous discourses and exclude those which correspond to infelicitous discourses? Hence the term of “strong generative capacity” taken from formal grammars.

Expressivity and comparison of models of discourse structure

Several discourse annotated corpora now exist for NLP. But they use different, not easily comparable annotation schemes: are the structures these schemes describe incompatible, incomparable, or do they share interpretations? In this paper, we relate three types of discourse annotation used in corpora or discourse parsing: (i) RST, (ii) SDRT, and (iii) dependency tree structures. We offer a comm...

Robust Text Analysis via Underspecification

This paper is concerned with the robust analysis of the discourse structure of a text via underspecification. Most current discourse theories (e.g. Rhetorical Structure Theory (RST) by Mann and Thompson (1988), Abduction by Hobbs et al. (1993) or Segmented Discourse Representation Theory (SDRT) by Asher (1993)) require detailed world and context knowledge for the derivation of the discourse str...

Logic-Based Rhetorical Structuring for Natural Language Generation in Human-Computer Dialogue

Rhetorical structuring is field approached mostly by research in natural language (pragmatic) interpretation. However, in natural language generation (NLG) the rhetorical structure plays an important part, in monologues and dialogues as well. Hence, several approaches in this direction exist. In most of these, the rhetorical structure is calculated and built in the framework of Rhetorical Struc...

SDRT and Continuation Semantics

Segmented Discourse Representation Theory (SDRT) [2, 7] provides a dynamic semantics for discourse that exploits a rich notion of discourse structure. According to SDRT, a text is segmented into constituents related to each other by means of rhetorical relations; the resulting structure, known as a segmented discourse representation structure or SDRS has various semantic effects. This theory ha...

An Underspecified Segmented Discourse Representation Theory (USDRT)

There are two conceivable readings for (1). Either (a) it refers to the party or (b) Peter only disliked the food. Discourse grammars like Segmented Discourse Representation Theory (SDRT) offer an explanation for this phenomenon. SDRT an extension ofDRT (Kamp and Reyle, 1993) describes a complex propositional structure of Discourse Representation Structures (DRSs) connected via discourse relati...
