Abstract
Abstract The invention is directed to a system that can easily generate determination conditions and determine a plurality of similar junk electronic mail pieces based on one determination condition. An electronic mail determination system comprises a junk electronic mail determination processing section ( 2 ) for determining whether or not a given electronic mail piece through an input section ( 1 ) is junk based on the determination condition stored in a junk electronic mail determination condition storage section ( 3 ), an estimated junk electronic mail storage section ( 6 ) for storing the electronic mail piece if the electronic mail piece is determined junk by the junk electronic mail determination processing section, and a junk electronic mail exemplification learning section ( 7 ) for analyzing content information of the electronic mail piece stored in the storage section ( 6 ) for extracting a feature amount to determine that electronic mail is junk and adding the extracted feature amount to the junk electronic mail determination condition storage section as a junk electronic mail determination condition. A keyword vector is used as the determination condition.
