A study of a small corpus of pharmaceutical leaflets supports the hypothesis that a subset of Mann and Thompson’s Rhetorical Relations may hold within as well as between clauses, with one or more propositional arguments nominalised. This paper summarises the main results of this study and outlines a formal account of the phenomenon within a framework of discourse generation, whereby nominalisat...

We consider two hypotheses about how rhetorical structure and QUD structure might come together to provide a more general pragmatic theory. Taking SDRT ([2]) and some basic principles from [18]’s QUD framework as starting points, we first consider the possibility that rhetorical relations can be modelled as QUDs, and vice versa. We ultimately reject this hypothesis in favor of the possibility t...

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...

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...

Research on citations has generally examined citations as part of a system of rewards or as a rhetorical tool for strengthening arguments. This study examines the role of citations both as reward and as rhetoric. The reward system was examined by tracing over time the citation patterns of 13 research articles by two groups of scientists in chaos theory. The rhetorical practices were examined by...

This paper addresses semantic ellipsis control in language generation for humancomputer dialogue. For this, the rhetorical structure of the dialogue is used, as well as a repository of facts that are accepted by the recipient of the utterance. Rhetorical structure is represented in the framework of SDRT, where rhetorical relations are grouped in “confirmation” and “contradiction” relations; the...

In this paper, we present a prototype that helps visualizing the relative importance of sentences extracted from medical texts using Embodied Conversational Agents (ECA). We propose to map rhetorical structures automatically recognized in the documents onto a set of communicative acts controlling the expression of an ECA. As a consequence, the ECA will dramatize a sentence to reflect its percei...
