This work aims to explore the correlation between the discourse structure of a spoken monologue and its prosody by predicting discourse relations from different prosodic attributes. For this purpose, a corpus of semi-spontaneous monologues in English has been automatically annotated according to the Rhetorical Structure Theory, which models coherence in text via rhetorical relations. From corre...

Lexical cues are linguistic expressions that can signal the presence of a rhetorical relation. However, such cues can be ambiguous as they may signal more than one relation or may not always function as a relation indicator. In this study, we first conduct a corpus-based analysis to derive a set of n-grams as potential lexical cues. These cues are then utilized in graph-based probabilistic mode...

In this position paper, we argue Ibr the need for a generation system to represent communicative goals (i.e., goals that express the speaker's intent to aflect the bearer's mental attitudes), at least if certain tasks are to be achieved. We lurther argue that, wlfile rhetorical relations might be recoverable t tom other Iactors, they appear to be a useful level of abstraction to maintain about ...

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...

Previous work on discourse parsing has mostly relied on surface syntactic and lexical features; the use of semantics is limited to shallow semantics. The goal of this thesis is to exploit event semantics in order to build discourse parse trees (DPT) based on informational rhetorical relations. Our work employs an Inductive Logic Programming (ILP) based rhetorical relation classifier, a Neural N...

Discourse connectives can show sense ambiguities, in that they can signal more than one possible rhetorical relation. The aim of this study is discover how to disambiguate such discourse connectives using a statistical model. Six discourse connectives (after, as soon as, before, once, since and while) which show ambiguities in the sdrt (Segmented Discourse Representation Theory (Asher & Lascari...

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...

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...

The AlethGen tool has been used to build a system for automatically generating replies to complaints, for a European mail-order company. In the current version, letters are generated in French. AlethGen consists of several modules: the text deep structure planner (or conceptual planner), the text surface structure planner (or rhetorical planner), the computation of pronouns and quantifiers, and...

In this paper, we discuss dependencies between rhetorical discourse structure and relevance implicatures. We follow [3] and infer relevance implicatures from the assumption that an answer provides optimal information for solving an explicitly or implicitly given decision problem of the inquirer. Such a decision problem can be identified with a question raised in the conversation. Background que...
