Communicative Principles And Utterance Planning

The paper discusses utterance planning in information-seeking dialogues and advocates a view of gradual speci cation of the communicative goal. In Constructive Dialogue Management, the set of beliefs that is intended to be communicated to the user is re ned with regard to communicative principles so that the utterance is relevant and appropriate in the context. Communicative principles describe rational and cooperative action, and they provide a uniform basis for planning by determining the appropriate continuation of the dialogue as well as the contextually relevant realisation of the goal. With their help the generation gap between what to say and how to say it can be bridged.
