Abstract
A method and system for characterizing the content of a document is disclosed. The method and system comprise identifying a plurality of discourse referents in the document, dividing the document into topically relevant document segments, and resolving co-referentiality among the discourse referents within, and across, the document segments. The method and system also comprises calculating salience values for the discourse referents based upon the resolving step, and determining topic stamps for the document segments based upon the salience values of the associated discourse referents. Finally the method and system comprise providing summary-like abstractions, in the form of capsule overviews of each of the segments derived from its topic stamps. In so doing, a capsule overview is derived for the entire document, which will depict the core content of an average length article in a more accurate and representative manner than utilizing conventional techniques.
