Query-Oriented Data Cleaning with Oracles

Summary: QOCO: query-oriented data cleaning via edits to the DB driven by domain-expert oracle crowds, to improve query results. NP-hardness of minimizing interactions, heuristics, and a prototype with experiments on correcting incorrect and missing tuples. (summarized by gpt-5-nano on Feb 09 2026)
