Workshop program

Applications utilizing spoken natural language interaction are becoming increasingly common, mainly due to the development of speech technology. Apart from speech recognition and speech synthesis, however, these systems require dialogue capabilities that would allow users to be engaged in a natural and efficient interaction.

For the sake of robustness and portability current practical dialogue systems tend to rely on simple models for dialogue management (e.g. state transition diagrams or dialogue grammars) and simple representations (if any) of domain or task knowledge (e.g. frames) and for certain applications, such as information retrieval from a database, these models actually appear to be sufficient. On the other hand, dialogue models developed within AI tend to emphasize the relation between utterances and speakers' goals and plans, the importance of being able to reason about other agents' beliefs and intentions, and the need for domain knowledge and discourse representation for resolving anaphoric and deictic references. Somewhere in between we also find proposals that either augment the simpler dialogue models with generic and specific domain knowledge, or restrict the role of plan inference to specific situations. The workshop aims at studying the need for knowledge and reasoning in dialogue systems from theoretical and practical perspectives. Besides the innovative aspect of research, an emphasis is also laid on the importance of implemented dialogue systems as test-beds for evaluating the usefulness of theories and ideas, and on improvements in practical system abilities supporting a more natural and efficient interaction. We primarily seek contributions which discuss one or more of the following issues:


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.
According to IJCAI rules, all workshop attendees must register for the main conference.

Workshop format

Ample time is allowed for commenting on the papers and open group discussion, thus ensuring time for discussions that go beyond ordinary conference style commenting. The workshop is intended to be a genuinely interactive event and a forum where new ideas and insights can take form via the collaboration of experts with diverse backgrounds. Demonstration of software could be organised as part of the main IJCAI conference.

Program comittee
