| Abstract(in English) | The volume of mass unsolicited electronic mail, often known as spam, has recently increased enormously and has become a serious threat to not only the Internet but also to society. This paper proposes a new spam detection method which uses document space density information. Although it requires extensive e-mail traffic to acquire the necessary information, an unsupervised learning engine with a short white list can achieve a 100% recall rate and 100% precision. A direct-mapped cache method contributes handling of over 12,500 e-mails per second. Experimental results, which were conducted using over 50 million actual e-mails, are also reported in this paper. |
