This paper reports on considerations and steps towards standardization [2] of the collaborative learning environment. This standardization will extend and widen the field of applications possible within the collaborative learning paradigm, and will make possible the usage of the fruits of years of research and individual implementations of the concept of collaborative learning, from our own lab...

To support learners during collaborative problem solving, developing a deeper understanding of collaborative dialogue is essential. This paper focuses on one important aspect of collaborative dialogue: expressions of uncertainty. In a study of undergraduate novice computer science students working in pairs, we observed that the students who produced the lowest quality solutions expressed uncert...

We have developed a novel methodology combining hierarchical task networks with traditional dialogue trees that both partially automates dialogue authoring and improves the degree of dialogue structure reuse. The key to this methodology is a lightweight utterance semantics derived from collaborative discourse theory, making it a step towards dialogue generation based on cognitive models rather ...

This paper addresses the challenge and potential of online higher and continuing education, of fostering and promoting, in a global perspective across time and space, democratic values working for a better world. Such values include mutual political and intercultural understanding, collaboration, and tolerance to cultural and ethical diversity, and they are mediated through collaborative dialog...

We report on the development of a prototype dialogue game for FCO-IM. Dialogue games are systems for executing controlled conversations. As part of an ongoing effort to analyze and support collaborative modeling processes by means of dialogue games, we created a dialogue game prototype for essential parts of the FCO-IM modeling process. The project was exploratory in nature, but results suggest...

This paper presents the current status of the research in the Higgins project and provides background for a demonstration of the spoken dialogue system implemented within the project. The project represents the latest development in the ongoing dialogue systems research at KTH. The practical goal of the project is to build collaborative conversational dialogue systems in which research issues s...

We present a taxonomy for classifying speech overlap in natural language dialogue. The scheme classifies overlap on the basis of several features, including onset point, local dialogue history, and management behavior. We describe the various dimensions of this scheme and show how it was applied to a corpus of remote, collaborative dialogue. Moving forward, this will serve as the basis for a co...

This paper applies Dynamic Syntax (Kempson et al., 2001) to dialogue modelling, and provides a characterisation of production that is relative to a converse process of tree growth which constitutes a parse check. As evidence for this approach, we place it in a psycho-linguistic perspective, using it to model (i) the parsing/production of elliptical expressions, (ii) dialogue properties such as ...

Collaborative control is a teleoperation system model based on human–robot dialogue. With this model, the robot asks questions to the human in order to obtain assistance with cognition and perception. This enables the human to function as a resource for the robot and help to compensate for limitations of autonomy. To understand how collaborative control influences human–robot interaction, we pe...
