This paper analyzed the widely used Nave Bayes filtering model based on risk minimization in spam filtering.With definition of the new risk factor,it put forward a new Nave Bayes filtering model based on line geometry division(LGDNBF).The new risk factor described risk of decisionmaking more precisely,and made LGDNBF extendible.The test result demonstrates that LGDNBF has better performance than traditional Nave Bayes filtering model based on risk minimization.
