URank: Formulation and Efficient Evaluation of Top-k Queries in Uncertain Databases
Summary: URank formulates top-k queries over uncertain databases using possible-worlds semantics. It fuses score-based and probability-based ranking via a new processing framework atop existing query engines, enabling efficient search for meaningful top-k results.
