Traditional plan recognition systems try to recognize a user's domain plan from the user's queries. In contrast, the Interactive Discourse Planner (IDP) tries to recognize an expansion of its own text plan from the user's queries. During interaction, IDP builds a text plan in reaction to user feedback that it uses as the discourse context. IDP uses this text plan to analyze user questions for i...

In this paper we argue that a formal discourse-or dialogue-oriented theory of interpretation does not presuppose a dynamic notion of meaning. For the compo-sitional interpretation of anaphorical or other rhetorical relations in discourse, a richer notion of conjunction may be needed, but not a dynamic notion of meaning. The dynamics of interpretation can be understood to reside in the (classica...

This paper reports the analysis of the online discourse of 44 sixth-grade students on an online platform in a Hong Kong primary school in the academic year of 2005-2006. A framework of two-step categorization is adopted to identify the patterns in a sustained knowledge building discourse, which integrates a category of four basic types of notes and SOLO taxonomy assessing the structural complex...

In this paper, I examine the role of intentional and informational structure in enabling a system to generate coherent multi-sentential texts in interactive settings. I review the plan-based model of discourse generation that I and my colleagues have developed, and examine the role of the speaker's communicative plans in generating expository text in an interactive environment. I provide exampl...

A multimodal analytic framework is introduced to contribute to a discourse-oriented study of the creation of visual information. While much visually based research focuses on the image artifact, an ongoing study seeks to shed light on the phenomenon of image creation as a communication practice. This requires a content analytic methodology capable of addressing issues related to modalities of e...

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...

This talk will present results from recent work that uses language and discourse to capture social dynamics during collaborative interactions. I will introduce group communication analysis (GCA), a novel approach for detecting emergent learner roles from the participants’ contributions and patterns of interaction. This method makes use of automated computational linguistic analysis of the seque...

This volume explores the relationship between gender and language through the analysis of discourse in interaction. Some chapters compare the discourse of females and males; others analyze interaction among fe­ males. All the analytic chapters both provide model analysis of conversa­ tional interaction and make significant theoretical contributions to the literature on gender and language. Of t...

The purpose of the study was to analyze patterns of elementary school students' peer interaction in a computer-supported classroom. The problem addressed in the study was whether students representing different level of school achievement and gender would productively participate in progressive discourse. Technological infrastructure of the study was provided by the Computer-Supported Collabora...

We show that in modeling social interaction, particularly dialogue, the attitude of obligation can be a useful adjunct to the popularly considered attitudes of belief, goal, and intention and their mutual and shared counterparts. In particular, we show how discourse obligations can be used to account in a natural manner for the connection between a question and its answer in dialogue and how ob...
