Abstract: Text filtering is the procedure of retrieving documents relevant to the requirements of specific users from a large-scale text data stream. This paper introduces a text filtering system merging topic classification based on vector space model and sentiment classification based on support vector machine. The experimental results show this method has high classification precision and recall.
