Structured Queries Over Web Text

The Web contains a vast amount of text that can only be queried using simple keywords-in, documentsout search queries. But Web text often contains structured elements, such as hotel location and price pairs embedded in a set of hotel reviews. Queries that process these structural text elements would be much more powerful than our current document-centric queries. Of course, text does not contain metadata or a schema, making it unclear what a structured text query means precisely. In this paper we describe three possible models for structured queries over text, each of which implies different query semantics and user interaction.
