Nu-BDI: Norm-aware BDI Agents

Systems of autonomous and self-interested agents interacting to achieve individual and collective goals may exhibit undesirable or unexpected properties if left unconstrained. Using deontic concepts of obligations, permissions and prohibitions to describe, what must, may and should not be done, norms have been widely proposed as a means of defining and enforcing societal constraints. Recent efforts to provide norm-enabled agent architectures that limit plan choices suffer from interfering with an agent’s reasoning process, and thus limit autonomy more than is required by the norms alone. In response, in this paper we describe an extension of the BDI architecture which enables normative reasoning, providing agents with a means to choose and customise plans (and their constituent actions), so as to ensure compliance with norms.
