Rule based interactive Chinese spam filtering method

Abstract

The invention relates to a rule based interactive Chinese spam filtering method. The method comprises a first step of extracting a Chinese spam filtering rule from Chinese spam samples; a second step of training by use of an improved genetic algorithm to obtain an optimum weight distribution of the rule; a third step of intensifying interaction between a user and a server, collecting and analyzing false negative and false positive information that are fed back by the user; and a fourth step of regulating the weight of a sensitive rule in time through an incremental learning method. In the method, the rule weight distribution is trained by use of the improved genetic algorithm, the false negative and false positive information is collected through interaction between the user and the server, and the rule weight is corrected by use of the incremental learning method according to an analysis result, so that false positive rate and false negative rate are lowered, and the filtering adaptivity is improved. The interactive filtering method reduces misjudgement and has a better filtering effect while guaranteeing that identification rate of spam is not lowered. The incremental learning method lowers the retraining frequency, makes weight updating faster, and improves the overall performance of a filtering system.

Description

technical field [0001] The invention relates to the technical field of the Internet, and specifically discloses a rule-based interactive Chinese spam filtering method. Background technique [0002] E-mail has always been one of the most important applications of the Internet. The early design of e-mail system was based on a basic assumption that the sender is credible, so the security of the e-mail system was rarely considered. With the rapid development of the Internet, the e-mail system is becoming more and more popular, followed by more and more serious security problems, the most important of which is the flood of spam, most mailboxes receive a large number of emails every day Spam brings huge loss and inconvenience to the society, collective and individual. How to effectively prevent spam has become the most serious problem facing the current mail system. [0003] People have tried every means to fight against spam, such as black and white list technology, filtering t...

AI Technical Summary

Problems solved by technology

Although SpamAssassin was designed with multi-language compatibility in mind, due to the huge difference between Chinese and English languages, its actual effect of filtering Chinese spam is not satisfactory

At the same time, it has no interaction between the user and the server on the correctness of the judgment, and lacks a mechanism for timely handling of wrong judgments
