Research on Chinese Key Words Mining with Malicious Jamming in English

With the rapid development of World Wide Web, the Web malicious attackers have taken the initiative jamming in Chinese to transform the form of the key words to be avoided being mined by the software existed. So how to filter the unhealthy Web page quickly and effectively has become the main content of the Web security. Because of the limitation of traditional rigid strings matching on the key words mining in Chinese, people have turned to research flexible string matching. Based on the Zhou-Zhang algorithm and the technique of key words mining in Chinese, this paper designed and realized a key words mining system about malicious jamming in English. The details in the design of the program and the realization of the process are introduced. The experiments prove that more than 98% of the key words about malicious jamming in English in the document could be mined and then be judged whether it is healthy by this system accurately.
