垃圾邮件过滤系统的设计

伴随着电子邮件的广泛使用,垃圾邮件日益泛滥,严重影响了人们正常的工作、学习和生活。如今新型的垃圾邮件变化多端,使得传统的、单一的垃圾邮件过滤方法对新型垃圾邮件已经无能为力。针对这一难题,介绍了当前已经应用于垃圾邮件过滤领域主流的3种垃圾邮件过滤技术。通过详细分析各种技术的优缺点,对黑白名单过滤技术、基于规则的过滤技术和贝叶斯过滤技术进行整合,从而建立了一个分层次的垃圾邮件过滤系统模型,并对该过滤系统进行了性能分析。

Design of Spam Filtering System

Along with wide application of e-mail nowadays,a large number of spam flood into people's life and bring catastrophe to their work and study.Now new spam is changeable which makes traditional and single method for anti-spam powerless.In response to this problem,three popular spam filtering technologies were introduced,which have been implemented on spam filtering field.After analyzing their advantages and disadvantages,The white and black lists technology,Rule-based filtering technology and Bayesian filtering technology to make the best use of the advantage of these algorithms were integrated.Consequently a layered spam filtering system model was set up,and the performance analysis of the system was made.
