A Resolution Procedure for Description Logics with Nominal Schemas

We present a polynomial resolution-based decision procedure for the recently introduced description logic \(\mathcal{ELHOV}_{n}(\sqcap)\) , which features nominal schemas as new language construct. Our algorithm is based on ordered resolution and positive superposition, together with a lifting lemma. In contrast to previous work on resolution for description logics, we have to overcome the fact that \(\mathcal{ELHOV}_{n}(\sqcap)\) does not allow for a normalization resulting in clauses of globally limited size.
