ARCHITECTURES FOR 2ND GENERATION KNOWLEDGE-BASED SYSTEMS

This chapter deals with the concept and examples of structured knowledge based systems. First, an evaluation of the first generation knowledge representations is summarized. Second, the role of deep knowledge is commented together with the knowledge structuring approaches based on the knowledge level specification of an agent and the task based approach for symbolic representation. Third, several knowledge architectures are commented since SOAR, for general problem solving to the physical behavior representation architectures. Finally, two architectures developed by the author to deal with flood management problems are presented as examples of real world knowledge based systems with complex structure.
