People are puzzled about how to get the knowledge that they need in the huge amount of information from Internet nowadays. The application of Web mining technology is a way to solve this problem. In this paper,the Web Content Mining(WCM), the Web Structure Mining(WSM) and the Web Usage Mining(WUM) are discussed from their contents, research status and development direction. The WCM consists of Web Information Extraction(Web IE) and Web Information Retrieval(Web IR). The process of Web IE includes vector expressing, character extracting, character reducing and text mining. As to Web IR, it is described from the principle, classification and latest achievement of the search engine. The algorithms and processes of WSM and WUM are also introduced in the paper.
