Abstract
Systems and methods that identify and extract information from articles are described. In one embodiment, a search engine implements a method comprising receiving a plurality of articles, and identifying at least a first article as a shopping article. The method can further comprise receiving a search query for an item, selecting the first article as associated with the search query, and identifying a first attribute associated with a first item relevant to the search query from the first article based at least in part on the search query.
