Method and system for indentifying 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 representing candidate significant topics in the document, clustering the simplex noun phrases by head, and ranking the simplex noun phrases according to a significance measure to indicate the relative importance of the simplex noun phrases as significant topics of the document. Furthermore, the output can be filtered in a variety of ways, both for automatic processing and for presentation to users.
