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...

In this paper we introduce “clipping,” a new method of syntactic approximation which is motivated by and works in conjunction with a sound and decidable denotational model for...
