Soundness Preserving Approximation for TBox Reasoning in R
Abstract. TBox reasoning in description logics is hard. For example, reasoning in SROIQ (i.e. OWL2-DL) is N2EXPTIME-complete; even with R, a fragment of SROIQ supporting ALC GCIs a...

Towards Soundness Preserving Approximation for ABox Reasoning of OWL2
ABox Reasoning in large scale description logic (DL) knowledge bases, e.g. ontologies, is important for the success of many semantic-enriched systems. Performance of existing appro...
