METHOD AND SYSTEM FOR IDENTIFYING SIGNIFICANT TOPICS OF A DOCUMENT

摘要

A "domain-general" method for representing the "sense" of a document includes the steps of extracting a list of simplex noun phrases (16) representing candidate significant topics in the document, clustering the simplex noun phrases by head (18), and rankiing the simplex noun phrases (20) according to a significance measure to indicate the relative importance of the simplex noun phrases as significant topic of the document. Furthermore, the output can be filtered in a variety of ways, both for automatic processing and for presentation to users.
