Well-Founded Semantics for Extended Datalog and Ontological Reasoning
Summary: Extend well-founded semantics to Datalog+/- with negation under the unique-name assumption, enabling nonmonotonic ontological reasoning over existential-rule ontologies. Prove decidability for guarded Datalog+/- under WFS and give tight complexities: PTIME data, 2-EXPTIME combined for Boolean CQs. (summarized by gpt-5-mini on Feb 09 2026)
