SPROUT2: A Squared Query Engine for Uncertain Web Data

Summary: SPROUT2 is a squared query engine for uncertain web data, enabling probabilistic queries over web tables, Google Fusion Tables, and Google Squared-derived uncertain tables. The demo centers SPROUT for ad-hoc structured querying and scenario-driven tours (movies, biomass facilities, corporate data), illustrating end-to-end probabilistic querying across heterogeneous sources.
