Abstract
An automatic abstract generation system including a document structure analyzer is described. From a document, the system extracts a text st ructure representing rhetorical relations among sentences and sentence chunks. The system evaluates sentence importance based on the analyze d structure and decides which sentence should be discarded from an abs tract. It also attempts to generate an abstract consistent with the or iginal text by replacing connective expressions.Generated abstracts we re evaluated from two points of view: the cover rate of key sentences; and the quality as document presentation media. Both experimental res ults proved the generated abstracts to be valid.
