QOCO: A Query Oriented Data Cleaning System with Oracles
Summary: QOCO uses user-defined query-driven materialized views as triggers to surface still-missing or erroneous data. It crowdsources domain expertise (oracles) to diagnose/root-cause fixes, with pruning to minimize questions, demonstrated on a World Cup games database. (summarized by gpt-5-nano on Feb 09 2026)
