Cleaning Uncertain Data with Quality Guarantees

Summary: Proposes PWS-quality, an ambiguity metric for probabilistic databases under possible-world semantics. Develops polynomial-time optimal cleaning to maximize PWS-quality by probing uncertain objects; efficient evaluation for independent and ranking queries, with practical heuristics.
