- KurzfassungAbstract
We examine the complexity and expressivity of the combination of the Description Logic ALCQI with a terminological formalism based on cardinality restrictions on concepts. This combination can naturally be embedded into C^2, the two variable fragment of predicate logic with counting quantifiers. We prove that ALCQI has the same complexity as C^2 but does not reach its expressive power.
There is also an extended technical report.
