A Model of Task-Oriented Communication Based on Principles of Rational Action and Interaction
This paper presents a simple rule-based approach to express the rational behind physical actions and communicative acts by formally reconstructing the behavior of the agents involved on the basis of their mental states. The model of rational action and interaction is grounded on four principles comprising the concepts of mental initiative, physical activity, purposeful selection, and cooperation, which are expressed as inference rules. It is shown how the adequacy of a communicative act for achieving a certain task-oriented goal can be derived by deductive and abductive use of these rules, given a suitable environment in terms of the competence and the propositional attitudes of the agents involved. Finally, the potential of extending this basic model is sketched out.
