A New Approach Based on Logistic Equation for Spam Filtering
WU Cheng-yong · Journal of Inner Mongolia University · 2010
Along with the widespread use of internet,spam is becoming a threat against the system security.Feature extraction technology is an essential part of spam filtering,which directly affects the spam filtering precision.A new approach has been presented by analyzing the three influence factors used to denote the significance of feature items.The way of common feature extraction technology to generate the value of the feature items is discussed.This new approach combined the factors to show the feature's ability to filter spams,using the Logistic equation directly calculated from the combination of factors to denote the value of feature,then select the feature according to the value.The experimental results show that the new approach is superior in feature selection.
