A Decidable Extension of SROIQ with Complex Role Chains and Unions

Journal of Artificial Intelligence Research. 2013. Vol. 47. P. 809-851.
Mosurovic M., Krdzavac N., Graves H., Zakharyaschev M.

We design a decidable extension of the description logic SROIQ underlying the Web Ontology Language OWL 2. The new logic, called SR+OIQ, supports a controlled use of role axioms whose right-hand side may contain role chains or role unions. We give a tableau algorithm for checking concept satisfiability with respect to SR+OIQ ontologies and prove its soundness, completeness and termination.
