Types of Dialogue

There are various ways to classify dialogues (or their parts), e.g., according to the mode/channel (spoken, written, multimodal, etc.), media (telephone, face-to-face, etc.), expertise of the participants (asymmetrical: expert-novice or symmetrical), domain (travel, cooking, home-device operation, mathematics, electronics, etc.). We adopt a classification according to the communicative task that the dialogue participants try to accomplish through their interaction. We are interested in a comparison along various dimensions, such as the following:

• Similarities and differences w.r.t. dialogue phenomena, main challenges
• Dialog move taxonomies
• Distribution of information/knowledge needed to accomplish the task
• Requirements on dialogue and task modelling
