Abstract
A semantic vector is generated for a search term based upon a global frequency of other, closely related terms within a corpus that is used to compute the semantic vector relative to the search term. The semantic vector is used in connection with a textual search engine, responsive to a user query comprising a search term, to promote any of documents and sites within results returned to the query by the search engine that contain other, closely related terms that strongly correlate with the search term.
