Design and Accomplishment of Web Information Filter and Monitor System in Campus Network

Aiming at the information conditions and the applications in campus network, a system for Chinese Web information filter and E-mail monitor is designed and implemented. The composing modules, arithmetic model and key technique of the system are described. The architecture of WinPcap-the kernel of datagram capturing technique is analysed, and the approaches to realize are showed. A mending vector space model, brought forward in the filtering system, is shown effective and doable by the experiments.
