Abstract:
Interposing a backward chaining reasoner between a knowledge base and a query manager yields an architecture that can support reasoning in the face of frequent changes. However, such an interposition of the reasoning introduces uncertainty regarding the size and effort measurements typically exploited during query optimization. This paper presents an algorithm for dynamic query optimization in such an architecture. Experimental results confirming its effectiveness are presented.
