On the reduction of discourse topic
Asher (2004) argues that developing a formal theory of discourse topic has proved difficult not least because ‘the notion of topic is not a homogeneous one’ [p1]. Against the theoretical background provided by SDRT, Asher helps clarify a number of issues, distinguishing sentence topic, contrastive topic, and discourse topic. He also contrasts ‘themes’, which play a role in the semantics of the ...
متن کاملAboutness topic, discourse topic and the structure of discourse
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...
متن کاملLinguistic Properties Matter for Implicit Discourse Relation Recognition: Combining Semantic Interaction, Topic Continuity and Attribution
Modern solutions for implicit discourse relation recognition largely build universal models to classify all of the different types of discourse relations. In contrast to such learning models, we build our model from first principles, analyzing the linguistic properties of the individual top-level Penn Discourse Treebank (PDTB) styled implicit discourse relations: Comparison, Contingency and Exp...
متن کاملSyntactic Form and Discourse Accessibility
One of the central issues in studies of reference is the relationship between morpho-syntactic form and the accessibility of discourse referents. However, most of the work in this area has been concerned primarily with reference to entities; considerably less work has addressed the relationship between syntactic form and the discourse accessibility of events. In this paper, we consider forms of...
