Base Claim:
1. A method for extracting quotations related to a product from a document, comprising: building a span query relevant to a feature associated with the product and a sentiment about the feature by: building syntactic templates from a lexicography relevant to the feature and the sentiment about the feature, wherein each syntactic template corresponds to multiple phrasings of the same meaning, and determining a first semantic template relevant to the syntactic templates; receiving a document; applying the span query to the document to generate a span query result, wherein the span query result includes a quotation from the document relevant to the feature and the sentiment about the feature, the quotation satisfying the first semantic template and including words within relative positions as constrained by the span query; and storing the span query result.
