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.
Supported by the grants N N206 3982 33 and N N206 399334 from the Polish Ministry of Science and Higher Education.
