We present a multi-context focused sequent calculus whose derivations are in bijective correspondence with normal natural deductions in the propositional fragment of the intuitioni...
Hybrid logics are a principled generalization of both modal logics and description logics. It is well-known that various hybrid logics without binders are decidable, but decision p...
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...
Abstract. We present the first terminating tableau calculus for basic hybrid logic with the difference modality and converse modalities. The language under consideration is basic m...
