Abstract

We give the first ExpTime (optimal) tableau decision procedure for checking satisfiability of a knowledge base in the description logic \(\mathcal{ALC}\), not based on transformation that encodes ABoxes by nominals or terminology axioms. Our procedure can be implemented as an extension of the highly optimized tableau prover TGC [12] to obtain an efficient program for the mentioned satisfiability problem.
