On the First-order Expressibility of Computing Certain Answers to Conjunctive Queries over Uncertain Databases
Summary: Characterize when CERTAINTY(q) is FO-expressible for Boolean conjunctive queries over key-violating (uncertain) databases, giving a necessary syntactic condition for queries without self‑join. For acyclic CQs the condition is also sufficient, yielding a decision procedure and a constructive FO‑rewriting (hence AC0).
