A Filtering Method Against Junk Mail Using Boosting Algorithm

To heighten the accuracy and effectiveness of filtering junk mail, this paper presents a mail filtering method based on filtering mail contents. The junk mail filter was constructed using Boosting algorithm. Referring to the evaluation index adopted in such fields as text classification and information retrieval, the evaluation system of presented junk mail filter was also established. The experiment and performance evaluation were implemented. Results show that, compared with traditional Bias algorithm, the performance of filtering method using Boosting algorithm is obviously superior to the method using traditional Bias algorithm.
