A Computational Model of Dialogue Initiative in Collaborative Discourse

This paper presents a model of dialogue initiative within a collaborative discourse. The importance of varying initiative between participants is validated both in theory and in experiments. For example, it was found that one initiative setting algorithm was up to 50% better than if initiative is random. Furthermore, a method for varying levels of initiative between participants is presented which relies on a relatively simple user model.
