Firstly, the paper introduces the theory of Web mining, including the definition, the task and the categorization of Web mining. Secondly, it also introduces several pivotal technologies in WTMiner (Web Text Miner), including word segmentation, term extraction and categorization method. In word segmentation, it uses two-way searching and hashing operation by means of the first Chinese character in a string to accelerate its speed.Considering the slow training speed to SVM (support vector machine), it uses K-nearest neighbor SVM to reduce the number of training set, so increase the algorithms speed greatly. ;;;
