Given a sentence such as, “I am not skiing today,” why does Extractor select “skiing” as a key phrase instead of “not skiing”?
The intention of Extractor is to capture the main topics that are discussed in the input document. Extractor does not attempt to convey exactly how these topics are discussed. For example, if a document discusses legal issues concerning guns, Extractor might suggest the key phrase “gun law”. This key phrase does not indicate whether the document supports strict legal control of guns or it is against any government involvement in gun control. The design of Extractor was based on a study of how authors use key phrases. We have examined several thousand documents with key phrases supplied by their authors. None of the key phrases we have seen so far include the word “not”.
