This paper proposes a computational system of narrative discourse generation and its implementation. In the system, Genette’s discourse theory is reconstructed as discourse techniques which transform the tree structure for a story into discourse structures. Also, we introduce Jauss’s reception theory to construct the control mechanism, which continues discourse generation through generation cyc...

This paper argues for a novel data structure for the representation of discourse referents. A so-called hashing list is employed to store discourse referents according to their grammatical features. The account proposed combines insights from several theories of discourse comprehension. Segmented Discourse Representation Theory (Asher, 1993) is enriched by the ranking system developed in center...

In this paper we investigate how discourse structure a ects the meanings of words and how the meanings of words a ect discourse structure We integrate three ingredients a theory of discourse structure called sdrt which represents discourse in terms of rhetorical relations that glue together the propositions introduced by the text segments an accom panying theory of discourse attachment called d...

OBJECTIVE Relation extraction in biomedical text mining systems has largely focused on identifying clause-level relations, but increasing sophistication demands the recognition of relations at discourse level. A first step in identifying discourse relations involves the detection of discourse connectives: words or phrases used in text to express discourse relations. In this study supervised mac...

In example (1), a sentence from a Wall Street Journal article taken from the Penn TreeBank corpus is further segmented into four EDUs, (1a), (1b), (1c) and (1d) (RST, 2002). Discourse segmentation, clearly, is not as easy as sentence boundary detection. The lack of consensus with regards to what constitutes an elementary discourse unit adds to the difficulty. Building a rule based discourse seg...

The paper addresses the relation between several dimensions along which discourse has been assumed to be structured – topical structure, hierarchical structure, QUD-structure and thematic structure – and points at previously undescribed mismatches between those. BACKGROUND ASSUMPTIONS: As discourse progresses, the aboutness topic of a sentence (Reinhart, 1981; Roberts, 2011; Krifka, 2007) may r...

We present extensive evaluations comparing the performance of taxonomy-based and corpus-based approaches on SimLex999. The results confirm our hypothesis that taxonomy-based approaches are more suitable to identify similarity. We introduce two new measures of evaluation that show that all measures perform well on a coarse-grained evaluation and that it is not always clear which approach is most...

The long term goal of this research is to develop a program able to produce an automatic segmentation and categorization of textual sequences into discourse types. In this preliminary contribution, we present the construction of an algorithm which takes a segmented text as input and attempts to produce a categorization of sequences, such as narrative, argumentative, descriptive and so on. Also,...

Expectations about the correlation of cue phrases, the duration of unfilled pauses and the structuring of spoken discourse are framed in light of Grosz and Sidner’s theory of discourse and are tested for a directions-giving dialogue. The results suggest that cue phrase and discourse structuring tasks may align, and show a correlation for pause length and some of the modifications that speakers ...
