1. A method for unsupervised determination of relational information from a corpus of text, comprising the steps of: (a) employing a first module that develops a heuristic model configured for extracting relationships from text, each relationship comprising a tuple; (b) employing a second module that uses an extractor and the heuristic model to automatically discover and extract a plurality of tuples from the corpus of text, wherein the extractor provides the plurality of tuples by tagging at least a portion of words within the corpus of text with each tagged word's most probable part of speech, without parsing the corpus of text and without generating a parse tree; and (c) providing one or more of the unparsed tuples in response to a query.
