Large knowledge based systems: an efficient approach

The authors propose an architecture for an integrated data/knowledge-based system (KBS) centered on a global data/knowledge dictionary and directory. The process of developing a KBS based on Prolog implementation schemes was studied an an architecture proposed which allowed the extensional (fact) portion of the knowledge base to exceed the KBS-resident system´s memory. Under this architecture approach, the extensional portion of the knowledge base was integrated with the databases into a combined data/knowledge based system
