Abstract:

We present a novel mechanism for the detection and resolu- tion of conflicts within norm-regulated virtual environments, populated by agents whose behaviours are regulated by explicit obligations, permis- sions and prohibitions. A conflict between norms arises when an action is simultaneously prohibited and obliged or prohibited and permitted. In this paper, we use first-order unification and constraint satisfaction to detect and resolve such conflicts, introducing a concept of norm cur- tailment. A flexible and robust algorithm for norm adoption is presented and aspects of indirect conflicts and conflicts across delegation of actions between agents is discussed.
