TAILIEUCHUNG - Báo cáo khoa học: "Coherence in Spoken Discourse*"

This paper explores the possibilities and limits of a discourse grammar applied to spontaneous speech. Most discourse grammars (. SDRT, Asher, 1993; RST, Mann & Thompson, 1988) tend to be descriptive theories of written discourse which presuppose a coherent structure. This structure is the outcome of a goal directed planning process on the part of the producer. In order to obtain a better understanding of the planning process we analyse spoken discourse elicited in an experimental setting. . | Coherence in Spoken Discourse Heike Tappe and Frank Schilder Computer Science Department Hamburg University Vogt-Kolln-Str. 30 D-22527 Hamburg Germany tappe schilder @ Abstract This paper explores the possibilities and limits of a discourse grammar applied to spontaneous speech. Most discourse grammars . SDRT Asher 1993 RST Mann Thompson 1988 tend to be descriptive theories of written discourse which presuppose a coherent structure. This structure is the outcome of a goal directed planning process on the part of the producer. In order to obtain a better understanding of the planning process we analyse spoken discourse elicited in an experimental setting. Subjects describe the pixel-per-pixel development of sketchmaps on a computer screen. This forces the speakers to conceptualise the perceived state of affairs plan their discourse and produce a description of the drawing at the same time. Thus we find evidence for the planning process in the recorded data and can show that the discourse structures are less globally coherent than those underlying written text. In our paper we discuss to what extent a flexible discourse grammar based on a Tree Description Grammar TDG Schilder 1997 can handle such data. 1 Introduction We investigate in this paper to what extent a discourse grammar is capable of analysing spontaneous speech that is obviously not as well structured as written text. The example text discussed contains questions and remarks which do not seem to be part of the discourse. Nevertheless we believe that the entire spoken discourse is to be represented by one discourse structure. Evidence for this assumption comes from the observation that anaphoric references are made between questions which apparently This work is partly funded by the German Science Foundation DFG research project Conceptualization Processes in Language Production an Empirically Founded Model on the Basis of Event Description Funding Number HA 1237 101 . comment on
