The Spam Filtering Technology Based on SVM and D-S Theory

The development of spam techniques and rapid increase of spam amount poses a severe challenge to anti-spam technologies. Given the limitation of classification based on mail body textual content, this paper focuses on designing the spam discrimination model based on SVM and D-S theory, which uses SVM with probability to classify e-mail, according to the features of mail headers and mail body respectively, and uses D-S Theory to judge the combination result. Experimental result indicates that the proposed model can improve the accuracy of spam identification.
