Method for automatically filtering junk mail and system thereof

Abstract

The invention relates to a method for automatically filtering junk mails and a system thereof. The method for automatically filtering junk mails comprises the following steps: S1, a client receiving mails; S2, performing word segmentation operation on the mail content; S3, performing sample classification by using naive Bayes; S4, calculating the occurrence probability of each category under the occurrence condition of the item; if the mail is a normal mail, sending the mail to a client; and if the mail is a junk mail, cleaning the mail. According to the method, the probability probe of the Bayesian theorem is adopted for judgment. The types of the to-be-classified items are calculated by learning the mail word set samples through Bayesian classification, and the junk mail is finally intercepted according to calculation processing results, so that the effect is very obvious, the junk mail harassment frequency is greatly reduced, and the optimal user experience is provided for users.

Description

technical field [0001] The invention relates to the technical field of mail filtering methods, and more particularly to a method and a system for automatically filtering spam.
