PROBLEM-SOLVING STRATEGIES FOR OPEN INFORMATION-SYSTEMS

Open information systems based on the open intelligent information sys tems architecture require appropriate strategies for problem solving. The problem solving strategies are the inferencing and control strateg ies that should exist in a knowledge-based type environment. The paper outlines the necessary strategies. The proposed strategies essentiall y augment the existing problem solving strategies, such as backward ch aining, forward chaining and mixed chaining. The strategies are implem ented in Prolog, and demonstrated using a prototype case.
