Planning at the Intention Level

Intentions enable an agent to achieve long-term goals. When an agent wishes to achieve an intention, it uses actions to bring it about.In this paper we investigate the relationship between intentions and actions. We begin by describing previous work involving a responsive agent capable of coherence-based belief revision. We then describe the implementation and testing of a system capable of representing and manipulating high level intentions. The implications of planning at the intention level are then discussed. We conclude that the architecture we put forward facilitates the development of agents which are able to plan pro-actively while still being able to cope with variation in the environment.
