Title: Evaluation Of Approaches For Dimensionality Reduction Applied With Naive Bayes Anti-spam Filters
Author: Almeida T.A.

Abstract: There are different approaches able to automatically detect e-mail spam messages, and the best-known ones are based on Bayesian decision theory. However, the most of these approaches have the same difficulty: the high dimensionality of the feature space. Many term selection methods have been proposed in the literature. Nevertheless, it is still unclear how the performance of naive Bayes anti-spam filters depend on the methods applied for reducing the dimensionality of the feature space. In this paper, we compare the performance of most popular methods used as term selection techniques, such as document frequency, information gain, mutual information, ÷2 statistic, and odds ratio used for reducing the dimensionality of the term space with four well-known different versions of naive Bayes spam filter. © 2009 IEEE.
