| Abstract: | Introduced the basic process of text categorization and several basic categorization methods such as naive Bayes and K nearest neighbor algorithm. Then it presented cover based constructive neural networks, and compared it with NB and KNN. Experimental resuits showed that this algorithm had better classification capability and it was fit for dealing with large- scale task of text categorization, accordingly it could overcome the disadvantage of traditional text categorization. |
