In this study, we investigated the psychological processes in spontaneous discourse comprehension through a network theory of discourse representation. Existing models of narrative comprehension describe the importance of causality processing for forming a representation of a text, but usually in the context of deliberately composed texts rather than in spontaneous, unplanned discourse. Our aim...

We present an implementation of a discourse parsing system for a lexicalized Tree-Ajoining Grammar for discourse, specifying the integration of sentence and discourse level processing. Our system is based on the assumption that the compositional aspects of semantics at the discourse-level parallel those at the sentence-level. This coupling is achieved by factoring away inferential semantics and...

Presupposition is a pervasive feature of human language. It involves many interesting interactions between the utterances of a discourse and the context of the discourse. In this paper we focus on issues of logical form connected with the interaction of presupposition and discourse context, and illustrate our theory with some implementational work using the active logic framework. After reviewi...

Attempts at discourse processing of spontaneously spoken dialogue face several difficulties: multiple hypotheses that result from the parser’s attempts to make sense of the output from the speech recognizer, ambiguity that results from segmentation of multi-sentence utterances, and cumulative error — errors in the discourse context which cause further errors when subsequent sentences are proces...

We present a tableaux-based model generation calculus for DRT, which gives us an incremental approach to discourse processing in the presence of world knowledge. We show the usefulness of such as system for several discourse phenomena.

Event Processing is an emerging area in the IT industry, evident by the burst of products, and attention given by analysts, venture capitals and enterprises. One of the notable characteristics of event processing is its close relation to temporal aspects. One can view event processing as getting a decision that is based on looking at the history of transitions in the domain of discourse. This g...

An agent's ability to understand an utterance depends upon its ability to relate that utterance to the preceding discourse. The agent must determine whether the utterance begins a new segment of the discourse, completes the current segment, or contributes to it. The intentional structure of the discourse, comprised of discourse segment purposes and their interrelationships, plays a central role...
