Human-robot collaboration may fail due to conflicts in beliefs or plans between cooperating partners, or due to robot errors. Dialogue is an intuitive way to resolve such conflicts due to miscommunication. The research demonstrated here explores the notion of using argumentation-based dialogue for human-robot interaction. The demonstration presents a proof-of-concept prototype of a logic-based ...

Curry I. Guinn Alan W. Biermann Department of Computer Science Duke University Durham, North Carolina 27706 ABSTRACT This paper presents a model of collaborative discourse which integrates problem-solving, discourse, and con ict resolution. Experimental evidence obtained from an implementation of this theory demonstrates the e ectiveness of the con ict resolution methods within the model. 1. Mo...

We describe a dialogue system that works with its interlocutor to identify objects. Our contributions include a concise, modular architecture with reversible processes of understanding and generation, an information-state model of reference, and flexible links between semantics and collaborative problem solving.

What would you say if your refrigerator told you, " You're having some friends round for hot chocolate later. Maybe you should order two cartons of milk " ? Of course, in Spoken Dialogue Technology, Michael McTear will not give an answer to the question of whether talking to domestic appliances makes sense, but he indicates that even a normal household, for instance, may offer a wide field of a...

We implemented and evaluated a collaborative lecture module in an ITS that models the pedagogical and motivational tactics of expert human tutors. Inspired by the lecture delivery styles of the expert tutors, the collaborative lectures of the ITS were conversational and interactive, instead of a polished one-way information delivery from tutor to student. We hypothesized that the enhanced inter...

BACKGROUND In order to facilitate the collaborative design, system dynamics (SD) with a group modelling approach was used in the early stages of planning a new stroke unit. During six workshops a SD model was created in a multiprofessional group. AIM To explore to which extent and how the use of system dynamics contributed to the collaborative design process. METHOD A case study was conduct...

This article reports on experiences with collaborative interface agents using spoken dialogue to collaborate with users working with graphical user interface applications. Collaborative interface agents provide users with the means to manage tasks and leave many of the details to the agent. The article presents four different collaborative agents and associated applications. It reports on lesso...

We describe a BDI (Belief, Desire, Intention) goal-oriented architecture for a conversational virtual companion embodied as a child’s Toy, designed to be both entertaining and capable of carrying out collaborative tasks. We argue that the goal-oriented approach supports both structured conversational activities (e.g., story-telling, collaborative games) as well as more “free-flowing” engaging d...

Motivational aspects are core to successful knowledge sharing and collaborative learning experiences. However, it still remains one of the great challenges to overcome motivational barriers when it comes to introducing information systems for collaborative learning at the workplace. In the context of an international research project we have taken motivational aspects into account during the de...
