There are many types of complicated data in the information ocean. How to acquire useful knowledgequickly from the information ocean is the very difficult. The Text Mining based on Web is the new research fieldwhich can solve the problem effectively. In this paper, we present a structure model of Text Mining and research thecore arithmetic - Classification arithmetic. We have developed the Text Mining system based on Web and appliedit in the modern long-distance education. This system can automatically classify the text information of education fieldwhich is collected from education site on Internet and help people to browser the important information quickly andacquire knowledge.展开更多
