| Abstract(in English) | In this paper, we discuss the methods of email filtering, to assign emails to the appropriate folders based on the user's classification strategy. Our contribution is to focus on the E-mail field with comparative study of email filtering in the framework of text filtering based on Naive Bayes. Although most previous works deal with email by the conventional text filtering method as the same way, email has the different characteristics comparing with other kinds of texts such as news and web pages so on. Characteristics of email are assumed as (1) the small number of terms included in it, and (2) its structure of fields. Considering these characteristics, we propose the methods to deal with email structure, estimate the term probability and the feature selection using the term weighting method to make the text filtering based on Naive Bayes optimized for email filtering. The experiment on a huge mail archive, the ENRON corpus, shows that the methods using Jeffreys Perks low improved about 10% of prediction accuracy for variety of known feature selection methods. |
