Description

This paper analyses several common algorithms for spam filtering and shows the advantages and disadvantages of these algorithms for spam filtering. Each algorithm is only suitable for filtering specific spam. Some algorithms are suitable for Chinese, and some algorithms perform well in English. In a lot of spam, it is not reliable and inefficiency to using a single algorithm to separate out spam. Thereby, in order to improve the accuracy and efficiency of spam filtering, composite intelligent algorithm, which integrates and improves the existing algorithms by utilizing the advantages of previous algorithms and avoiding their shortages, is proposed. Moreover, an intelligent method that it has the ability of self-learning by using the contents of the e-mails is introduced. Finally, the outcome of experiment shows that the intelligent method achieves a better efficiency and performance.
