Equality−Friendly Well−Founded Semantics and Applications to Description Logics
- Abstract:
-
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 particular, we provide a WFS for the recent Datalog family of ontology languages, which covers several important description logics (DLs). To do so, we generalize Datalog by non-stratified nonmonotonic negation in rule bodies, and we define a WFS for this generalization via guarded fixed point logic. We refer to this approach...
