relational databases to support DAML+OIL semantics. We design DLDB, a lightweight knowledge base system that has the capability of DAML+OIL inference and supports semantic web queries. Making use of the FaCT DL reasoner [Horrocks, 00], DLDB has been successfully implemented on a common RDBMS: Microsoft Access. It can process, store and query ...

Abstract : We present DLDB, a knowledge base system that extends a relational database management system with additional capabilities for DAML+OIL inference. We discuss a number of database schemas that can be used to store RDF data and discuss the tradeoffs of each. Then we describe how we extend our design to support DAML+OIL entailments. The most significant aspect of our approach is the ...

A practical SPARQL query often embeds several filters, which require comparisons between RDF results of different types. The type of RDF resources needs to be dynamically determined in the translation. In this paper, we propose an effective approach to support SPARQL queries over relational databases, with the above challenges in mind.

In this paper we describe Racer, which can be considered as a core inference engine for the semantic web. The Racer inference server o#ers two APIs that are already used by at least three di#erent network clients, i.e., the ontology editor OilEd, the visualization tool RICE, and the ontology development environment Protege 2.
