When a reasoning system encounters a contradiction like p&q=>false, it may try to eliminate it by retracting some belief that supports either p or q.

The model is implemented as a service of an agent programming shell we have created for enterprise integration. Keywords: credibility, retraction cost, conflict management, cooperative information systems, enterprise integration. 1.0 Introduction When a reasoning system encount...
