| 摘 要： | Classification algorithm is orc of the key techniques to affect text automatic classification system‘s performance, play an important role in automatic classification research area. This paper comparatively analyzed kNN. VSM and hybrid classification algorithm presented by our research group. Some 2000 pieces of Internet news provided by ChinalnfoBank are used in the experiment. The result shows that the hybrid algorithm‘s performance presented by the groups is superior to the other two allzorithms.

| Abstract: | Classification algorithm is one of the key techniques to affect text automatic classification system's performance, play an important role in automatic classification research area. This paper comparatively analyzed k-NN. VSM and hybrid classification algorithm presented by our research group. Some 2000 pieces of Internet news provided by ChinaInfoBank are used in the experiment. The result shows that the hybrid algorithm's performance presented by the groups is superior to the other two algorithms. |
