Spam filter for short message
短信过滤系统设计分析*

This paper proposed a content-based spam filter embedded in mobile phones.It used the balanced Winnow algorithm as the kernel classifier in the system,since the algorithm could classify texts faster,better and what's more,it allowed on-line setting.The Winnow classifier was suitable for systems which had limited resources and needed to be renewed at intervals.Then implemented a series of experiments to prove the good performance of the system,and analyzed the method from many aspects.This paper gave a statistic support for the information filters using balanced Winnow.
