An Algorithm of Chinese Keys Matching Used in Filtering Junk Mail

根据垃圾邮件过滤技术的现状,分析了常用的传统关键词匹配算法的弱点。

According to the technology status of filtering junk mail, the traditional keys matching algorithm in common use is analyzed and its weakness is pointed out.On the basis of traditional keys matching algorithm,an improved keys matching algorithm is proposed.This algorithm splits Chinese key into single words,scans the target text and finds out all formats derived from the original key.The target text is matched with the derived keys then.Moreover,this algorithm improves the flexibility and efficiency of key matching,and it can be applied in monitoring of forum articles,short message,and other filtering domains.
