SPROUT² 是一个查询应答系统，允许用户对网页中嵌入的表格、Google Fusion 表以及可从 Google Squared 的答案中提取的不确定表进行结构化查询。该服务的核心是 SPROUT，它是一个概率数据库查询引擎。该演示允许用户编写和提出他们选择的临时查询，还可以沿着预先安排的场景（例如电影演员和导演、生物质设施或利用公司数据库）浏览系统的功能。
SPROUT² 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.
