Dialogue frames in agent communication

Sophisticated models of inter-agent communication are making increasing use of intuitive notions of persuasion and negotiation. In this paper, a formal characterisation is provided which not only clearly distinguishes persuasion from negotiation, but also introduces three other dialogue types, and sets all five in a coherent framework. The notion of a dialogue frame is introduced, and is used to explore the dialogue typology and one of its important features, the concept of functional embedding. The approach offers a number of substantial benefits, including (i) the provision of definitions for classes of communicative encounters, (ii) improvements in expressive capability, (iii) facilitating comparison between diverse multi-agent research, and in some cases, (iv) reducing computational cost.
