To interact effectively, agents must enter into commitments. What should an agent do when these commitments conflict? We describe Coco, an approach for reasoning about which specific commitments apply to specific parties in light of general types of commitments, specific circumstances, and dominance relations among specific commitments. Coco adapts answer-set programming to identify a maximalsetofnondominatedcommitments. It provides a modeling language and tool geared to support practical applications.

Secure collaboration requires the collaborating parties to apply the
right policies for their interaction.  We adopt a notion of
conditional, directed norms as a way to capture the standards of
correctness for a collaboration.  How can we handle conflicting norms?
We describe an approach based on knowledge of what norm dominates what
norm in what situation.  Our approach adapts answer-set programming to
compute stable sets of norms with respect to their computed conflicts
and dominance.  It assesses agent compliance with respect to those
stable sets.  We demonstrate our approach on a healthcare scenario.
