随着 Internet普及和应用 ,电子商务和企业上网已经成为一种发展趋势 .网络的安全日益引起人们的关注 .提供一定的手段 ,实时对网络中的信息进行监测具有十分重要的意义 .本文利用中文文档信息处理中特定分类文档特征向量提取技术 ,为信息过滤提供依据 ;并且从信息过滤系统结构、网络信息捕获、网络协议分析等方面对网络信息过滤系统 ( NIFS)

With the development of the network technology, especially the fast growing of Internet, ecommerce becomes a fashion of our age. The network security is more concernful, it is important to monitor the information in and out the network in real time. Through the research on the theory of the document's presentation and the method of the Chinese document processing, the eigenvector is extracted and used as the filtering rule. The paper discusses the basic theory and implementation methods of NIFS in detail, including the system architecture, network information capturing and network protocol analyzing.
