When is Naive Evaluation Possible?
Summary: Shows naive evaluation yields certain answers iff queries are monotone under a semantics-induced ordering (equivalently preserved by appropriate homomorphisms). Presents a relation-based framework for many incompleteness semantics (incl. CWA) and identifies FO classes beyond UCQs that admit naive evaluation. (summarized by gpt-5-mini on Feb 09 2026)
