| With the development of Internet,Electronic mail has already became one of important tools for communication , At the same time it has taken us a lot of conveniences , the growing Spam have generated a lot of damage to economics and people's lives, ,the problems it takes has also became more and more terrible. Therefore, it is meanful to research and design a Spam Filtering with high efficiency. Nowadays.the technologies of Spam filtering are based on Internet. As a new technology, Grid has advantage in computing resource sharing. The thesis adopt this Grid technology which can make full use of Grid rescoures to distribute the classification of mail in the terminal nodes to some spare nodes and finally summarize the results of classification to key nodes through Grid, It can improve the accuracy and efficiency .we can realized that it is meanful in theory and valulable in practical to research the technology of Spam filtering based on Grid.The thesis firstly outline the concept of Spam, Analyze and compare the Spam filtering technology based on IP address ,rules and statistic.and described the technology of Chinese text splitter in the treatment of Chinese mail text ,Introduce the application of the method of bayes in Spam filtering technology, and comparize some normal ways of feature extraction words.and then induced some relavant concepts of Grid Service Architecture, technology of Grid ,and finally propose a Bayes algorithm based on Grid environment,and realize a Spam filtering system based on Grid. |
