Summary form only given. Though search on the World-Wide Web has focused mostly on unstructured text, there is an increasing amount of structured data on the Web and growing interest in harnessing such data. Moreover, structured data is starting to play a greater role in many of the social movements enabled by the Web, such as citizen participation in government. The paper describes several current projects at Google whose overall goal is enable people to create and share structured data on the Web and to leverage structured data in Web search. The author describes the system for crawling millions of "deepweb" sites, that offer access to high-quality data through HTML forms and the WebTables and Octopus Systems that leverage structured data in HTML tables and lists on the surface web and enable users to piece together multiple data sets. Finally, Fusion Tables is a recently launched data-management service that lets users create and visualize structured and easily and emphasizes the ability to collaborate with other data owners.
