摘　　要：电子邮件给人们带来极大便利,但垃圾邮件的日益泛滥,也给人们带来了极大的不便和危害。传统的邮件过滤方法的过滤精度较低,不能很好满足需要。文中提出了一种基于向量空间模型的电子邮件过滤系统,并对向量空间模型进行了改进:采用字作为文本向量的特征表示,并且在字频向量的特征提取时采用了一种新的特征提取函数,从而提高了邮件分类的精度,达到了较好的过滤垃圾邮件的目的。While the E-mail brings the great facility to people,but the increasing unsolicited bulk E-mail,also brings great inconvenience and danger to people.The filtering precision of methods used by traditional mail filters is relatively low,can't well satisfy the demand of filtering.This paper has proposed a kind of E-mail filter system based on vector space model with word as the characteristic of text vector,adopting a kind of new feature function whendrawing word frequency vector to increase the filtering precision,and has improved the vector space model and achieved better filtration of unsolicited bulk E-mail.
