Spam Filtering With Several Novel Bayesian Classifiers

Free registration required

Executive Summary

This paper presents spam filtering with three novel bayesian classification methods: Aggregating One-Dependence Estimators (AODE), Hidden Na?ve Bayes (HNB), Locally Weighted learning with Na?ve Bayes (LWNB). Other four traditional classifiers: Na?ve Bayes, k Nearest Neighbor (kNN), Support Vector Machine (SVM), C4.5 are also performed for comparison. Four feature selection methods: Gain Ratio, Information Gain, Symmetrical Uncertainty and ReliefF, are used to select relevant words for spam filtering. Results of experiments on two corpora show the promising capabilities of bayesian classifiers for spam filtering, especial for that of AODE.
