Mesa : A Search Engine for Querying Web Tables

The volume of structured data on the Web has grown considerably in the recent past. In contrast to unstructured (textual) documents, which can be searched through simple keyword-based interfaces, the presence of structure enables rich queries to be posed against Web data. In this paper we present a search engine designed for querying structured information sources on the Web and show how our system can support on-the-fly, complex queries over content published in hundreds HTML tables.
