We combine the modal logic S5 with the description logic (DL) ALCQI. In this way, we obtain a multi-dimensional DL, S5ALCQI, whose purpose is reasoning about change. S5ALCQI is ca...
This paper describes our current activities to supply extended reasoning support to knowledge engineers who are building terminologies using Description Logics (DL) reasoners. The...
We tackle the problem of defining a well-founded semantics (WFS) for Datalog rules with existentially quantified variables in their heads and negations in their bodies. In partic...
Abstract. Developing a good formalism and an efficient decision procedure for the instance checking problem is desirable for practical application of description logics. The data c...
