M defined by equation (6) and select the action for which the conditional risk is minimum. If more than one action minimizes R(ai |x), a tie-breaking criterion can be used. 4 A Three-Way Decision Approach to Email Spam Filtering In the naive Bayesian spam filter, an incoming email is classified as legitimate if the posterior odds ratio exceeds a certain threshold value. In our approach, 32 B. Zhou, Y. Yao, and J. Luo a pair of threshold values is used to make a three-way decision of an incoming email.

Consequently, we use SVM as a machine-learning algorithm to be applied to the chosen features. 3% for the last feature set. Based on the accuracy of the three experiments, unigram features outperform the other two types. Even though it is significantly better than the third one, its difference with the second feature set merits a discussion. Here, we would like to point out parameters – other than the accuracy of the results – which should be considered in choosing the list of features. The number of features is one of the main parameters.
