Abstract

We present and discuss some novel and somewhat surprising complexity results for a basic but significant fuzzy description logic (DL) which extends the classical \(\mathcal{ALC}\) language. In particular we show that checking the consistency of a concept or a KB in fuzzy DLs has a complexity which jumps from linear-time to EXPTIME-complete, while the subsumption problem is always (at least) as hard as in crisp DLs.
