Local closed world reasoning with description logics under the well-founded semantics
An important question for the upcoming Semantic Web is how to best combine open world ontology languages, such as the OWL-based ones, with closed world rule-based languages. One o...

Decidability Under the Well-Founded Semantics
The well-founded semantics (WFS) for logic programs is one of the few major paradigms for closed-world reasoning. With the advent of the Semantic Web, it is being used as part of r...

Queries to Hybrid MKNF Knowledge Bases through Oracular Tabling
An important issue for the Semantic Web is how to combine open-world ontology languages with closed-world (non-monotonic) rule paradigms. Several proposals for hybrid languages all...
