This study investigated the comparative effects of audio-visually prompted collaborative dialogue on the listening comprehension development of symmetrical, asymmetrical, and asymmetrical teacher-fronted EFL learner groups. Besides, it explored the attitude of the participants of the groups concerning the effectiveness of collaborative dialogue for their listening comprehension improvement. The...

This paper argues that developments in collaborative e-learning dialogue should be based on pedagogically sound principles of discourse, and therefore, by implication, there is a need to develop methodologies which transpose — typically informal — models of educational dialogue into cognitive tools that are suitable for students. A methodology of ‘investigation by design’ is described which has...

Dialogue systems need to be able to understand a user’s communicative intentions, reason with those intentions, form their own communicative intentions, and realize those intentions with actual language to be uttered to the user. Oftentimes in dialogue systems, however, what these communicative intentions actually correspond to is never clearly defined. We propose a descriptive model of dialogu...

Collaborative design is an iterative process of selecting and evaluating solutions under potentially conflicting requirements, a concept central to Building Information Modelling (BIM) implementation. Previous research has shown that design can be better understood via computational argumentation-based dialogue. We suggest that in BIM context different types of dialogue should be considered and...

This report is about the state of the art in dialogue management. We first introduce an overview of a multimodal dialogue system and its components. Second, four main approaches to dialogue management are described (finite-state and frame-based, information-state based and probabilistic, plan-based, and collaborative agent-based approaches). Finally, the dialogue management in the recent dialog...

This paper pursues a formal analogy between natural language dialogue and collaborative real-world action in general. The analogy dependson an analysis of two aspects of collaboration that figure crucially in language use. First, agents must be able to coordinate abstractly about future decisions which cannot be made on present information. Second, when agents finally take such decisions, they ...

We present the results of a study in which we contrast alternative forms of collaborative learning support in the midst of a collaborative design task in which students negotiate between increasing power and increasing environmental friendliness. Our research question is whether interactive instructional support in collaborative learning environments is more effective when it is offered as soli...

We present a formal model of agent collaborative problem solving and use it to define a novel type of dialogue model. The model provides a rich structure for tracking dialogue state and supports a wide range of dialogue, including dialogue which contributes to interleaved planning and execution of domain goals.
