SPROUT~2: A Squared Query Engine for Uncertain Web Data

摘要

SPROUT~2 is a query answering system that allows users to ask structured queries over tables embedded in Web pages, over Google Fusion tables, and over uncertain tables that: can be extracted from answers to Google Squared. At the core of this service lies SPROUT, a query engine for probabilistic databases. This demonstration allows users to compose and ask ad-hoc queries of their choice and also to take a tour through the system's capabilities along pre-arranged scenarios on, e.g., movie actors and directors, biomass facilities, or leveraging corporate databases.
