The study we report in this article addresses the results of comparing the rhetorical trees from two different languages carried out by two annotators starting from the Rhetorical Structure Theory. Furthermore, we investigate the methodology for a suitable evaluation, both quantitative and qualitative, of these trees. Our corpus contains abstracts of medical research articles written both in Spanish and Basque, and extracted from Gaceta Médica de Bilbao. The results demonstrate that almost half of the annotator disagreement is due to the (...) use of translation strategies that notably affect rhetorical structures. (shrink)

We present a corpus-based study of coherence in multimodal documents. We concern ourselves with the types of relationships between graphs and tables and the text of the document in which they appear. In order to understand and categorize the types of relations across modalities, we are making use of Rhetorical Structure Theory, and propose that this can adequately describe these types of relations. We analyzed a corpus comprising three different genres, and consisting of about 1500 pages of material and almost (...) 600 figures, tables and graphs. We show that figures stand in both presentational and subject matter relations to the text, and that the relationship between figures and text is one of a small set out of the larger possible rhetorical relations. We also discuss several issues that arise in the treatment of multimodal material, such as the potential for multiple connections between figure and text. (shrink)

Rhetorical Structure Theory has enjoyed continuous attention since its origins in the 1980s. It has been applied, compared to other approaches, and also criticized in a number of areas in discourse analysis, theoretical linguistics, psycholinguistics, and computational linguistics. In this article, we review some of the discussions about the theory itself, especially addressing issues of the reliability of analyses and psychological validity, together with a discussion of the nature of text relations. We also propose areas for further research. A follow-up (...) article will discuss applications of the theory in various fields. (shrink)

This article explores the role that markers play in the pragmatic discourse structure of Catalan and English oral narratives. It is argued that their meaning is directly related to the sort of coherence relation that they establish with preceding and following propositions and discourse segments, centring the discussion on four discourse structures/components: ideational, rhetorical, sequential and inferential. The aim is to show the textual form-pragmatic function relationship by means of specific lexical units placed at specific parts of the narrative. The (...) hypothesis held in this article is that pragmatic markers help in the organization of narrative segments and that their semanticopragmatic traits make them appropriate for their use in specific segments.
