Foundations of Uncertain-Data Integration
Summary: Extends LAV data integration to uncertain sources, with two settings and a containment framework using views over a mediated uncertain database. Proves global consistency-checking is intractable, identifies a polynomial case, and defines correct answers for uncertain LAV rather than traditional certain answers.
