I want to tell a story about computational approaches to discourse structure. Like all such stories, it takes some liberty with actual events and times, but I think stories put things into perspective, and make it easier to understand where we are and how we might progress. Part 1 of the story (Section 2) is the past. Here we see early computational work on discourse structure aiming to assign ...

We argue that discourse plans must capture the intended causal and decompositional relations between communicative actions. We present a planning algorithm, DPOCL, that builds plan structures that properly capture these relations, and show how these structures are used to solve the problems that plagued previous discourse planners, and allow a system to participate effectively and flexibly in a...

In this paper we present an overview of recent developments in discourse theory and parsing under the Linguistic Discourse Model (LDM) framework, a semantic theory of discourse structure. We give a novel approach to the problem of discourse segmentation based on discourse semantics and sketch a limited but robust approach to symbolic discourse parsing based on syntactic, semantic and lexical ru...

In this paper, we introduce LiveTree, a core component of LIDAS, the Linguistic Discourse Analysis System for automatic discourse parsing with the Unified Linguistic Discourse Model (U-LDM) (X et al, 2004). LiveTree is an integrated workbench for supervised and unsupervised creation, storage and manipulation of the discourse structure of text documents under the U-LDM. The LiveTree environment ...

Discourse markers are universal linguistic events subject to language variation. Although an extensive literature has already reported language specific traits of these events (e.g. [6,7,4,3,9]), little has been said on their cross-language behavior and, subsequently, on building an inventory of multilingual lexica of discourse markers. Thus, this work describes new methods and approaches for t...

Purpose: A primary goal of aphasia intervention is to improve everyday communication. Although a large body of research focuses on treatment generalization, transfer of learning to real-world interactions involving discourse does not always occur. The goal of an integrated discourse treatment for aphasia (IDTA) approach is to facilitate such generalization. This article reviews generalization d...

How do groups resist the apparently all encompassing discourse of management? Rejecting current theories of resistance as ‘re-appropriation’ or ‘micro-politics’, we argue that resistance may be thought about as hegemonic struggle which are undertaken by social movements. We identify four major resistance movements that engage with management: unions, organizational misbehaviour, civic movements...

We argue that Discourse Representation Structures form a suitable level of languageneutral meaning representation for micro planning and surface realisation. DRSs can be viewed as the output of macro planning, and form the rough plan and structure for generating a text. We present the first ideas of building a large DRS corpus that enables the development of broad-coverage, robust text generato...

We use systematic functional method to analyze and try to find out the estimated correlation behind several different texts. Ideology makes great influences on translation expression and strategy, which thus, is the product of the ideology. Language understanding means to obtain a semantic network and conditional information from a text in a deep sense.
