Abstract: Content filtering in network security is a new subject. At present, the research on content filtering technique focuses on examining and analyzing key words. This method brings the lower filtering precision. This paper founds a content filtering model based on vector space model that improves the filtering precision. And, the model keeps a better balance between the filtering precision and instantaneity.
