PDQ: Proof-driven Query Answering over Web-based Data
Summary: PDQ introduces proof-driven query planning over Web-based sources, generating plans from proofs that a query is answerable. Constraint-, access-, and cost-aware, it rewrites expensive queries via source relations, respects access restrictions, and selects low-cost plans from known costs.
