Paraconsistent Reasoning for Expressive and Tractable Description Logics
Abstract. Four-valued description logic has been proposed to reason with description logic based inconsistent knowledge bases, mainly ALC. This approach has a distinct advantage th...

Expressive ABox Reasoning with Number Restrictions, Role Hierarchies, and Transitively Closed Roles
We present a new tableaux calculus deciding the ABox consistency problem for the expressive description logic ALCNHR+ . Prominent language features of ALCNHR+ are number restricti...

RACER System Description
RACER implements a TBox and ABox reasoner for the logic SHIQ. RACER was the first full-fledged ABox description logic system for a very expressive logic and is based on optimized s...

Classifying Description Logics
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...

Decision Procedures for Expressive Description Logics with Intersection, Composition, Converse of Roles and Role Identity
In the quest for expressive description logics for real-world applications, a powerful combination of constructs has so far eluded practical decision procedures: intersection and ...
