The paper presents a prototype system HD-Rules (Hybrid integration of Description Logic and Rules) that integrates normal clauses under the wellfounded semantics with ontologies sp...

Fuzzy Description Logics have been proposed in the literature as a way to represent and reason with vague and imprecise knowledge. Their decidability, the empirically tractable an...
Effective systems for expressive description logics require a heavily-optimised subsumption checker incorporating a range of optimisation techniques. Because of the correspondence...
We describe a method for characterizing the expressive power of description logics. The method is essentially model-theoretic in nature, and it is applied to obtain expressiveness...
