4th Workshop on

Description of the Workshop

The workshop on Knowledge and Reasoning in Practical Dialogue Systems will focus on adaptivity in dialogue systems. We encourage both papers presenting successful adaptive dialogue systems as well as papers on potential drawbacks (or challenges).

This is the fourth workshop on Knowledge and Reasoning in Practical Dialogue System. The first workshop was organised at IJCAI-99 in Stockholm, the second workshop took place at IJCAI-2001 in Seattle, and the third workshop was held at IJCAI-2003 in Acapulco.

The current workshop includes research in three main areas: dialogue management, adaptive discourse planning, and automatic learning of dialogue policies. Probabilistic and machine learning techniques have significant representation, and the main applications are in robotics and information-providing systems.

The workshop notes contain 12 papers that address these issues from various view-points. The papers provide stimulating ideas and we believe that they function as a fruitful basis for discussions and further research.

Who should attend

This workshop aims at bringing together researchers and practitioners that work on the development of communication models that support robust and efficient interaction in natural language, both for commercial dialogue systems and in basic research.

It should be of interest also for anyone studying dialogue and multimodal interfaces and how to coordinate different information sources. This involves theoretical as well as practical research, e.g. empirical evaluations of usability, formalization of dialogue phenomena and development of intelligent interfaces for various applications, not excluding such areas as Robotics.

The workshop will encourage the participation of both system builders and theoretically oriented researchers, thus creating a forum for discussion across vocational and disciplinary borders. While taking practical applications and implemented dialogue systems as our point of departure, we emphasize the potential contributions of theoretical and empirical research: applications are the best testbeds for evaluating the usefulness and originality of theories and ideas.

Workshop format

The workshop will be kept small, with a maximum of 40 participants. Preference will be given to active participants selected on the basis of their submitted papers.

Each paper will be given ample time for discussion, more than what is customary at a conference. As said above, we encourage contributions of a critical or comparative nature that provide fuel for discussion. We also invite people to share their experiences of implementing and coordinating knowledge modules in their dialogue systems, and integrating dialogue components to other applications.
