The Complexity of Why-Provenance for Datalog Queries
Summary: Data- and complexity-theoretic analysis of why-provenance for Datalog queries, filling a literature gap with a sharp dichotomy. Recursive (even linear) Datalog why-provenance is intractable; non-recursive cases are highly tractable. (summarized by gpt-5-nano on Feb 09 2026)
