In this paper, we create a text filtering model based on VSM. In this model,Web text mming is an efficient technique,which discoveres valuable and potential knowledge from those unstructured texts. In this paper,we use VSM as the description of Web text and give a feature subset algorithm which is based on the Genetic Algorthm. This algorithm can greatly improve the efficiency of dealing with Web texts and give much better way to classify and cluster the texts. Our experiments show that this method is active well in feature dimension reduction.展开更多
