An approach to manage large inheritance networks within a DBS supporting nested relations

Abstract

When developing large scale knowledge-based systems concepts are required for handling large knowledge bases as well as for guaranteeing the integrity of the knowledge base contents In this paper we present an approach for managing structured inheritance networks in an andvanced database system. Actually, we develop concepts for handling a KL-ONE like formalisms in an extended relational database system supporting nested relations. Of special importance is the handling of the general graph structure provided by KL-ONE like formalisms within the tree structure offered by nested relations. The described approach is oriented towards the specific requirements which have to be met in a natural language processing environment.
