QFix: Diagnosing Errors through Query Histories
Summary: QFix diagnoses data-quality errors by tracing how queries affected data to derive explanations and repairs. Formalizes query-based diagnosis, provides exact diagnosis/repair methods, optimizations, a tunable accuracy–performance tradeoff to scale to large logs.
