Query processing of OWL-DL ontologies is intractable in the worst case, but we present a novel technique that in practice allows for efficient querying of ontologies with large Aboxes in secondary storage. We focus on the processing of instance retrieval queries, i.e., queries that retrieve individuals in the Abox which are instances of a given concept C. Our technique uses summarization and refinement to reduce instance retrieval to a small relevant subset of the original Abox. We demonstrate… CONTINUE READING
