Research on enhancing the effectiveness of the Chinese text automatic categorization based on ICTCLAS segmentation method

The article proposed a method that suggest a way to replace some lower category identification capacity items from the ICTCLAS segmentation result by drawing the feature items that owns a better category identification capacity from the 2-gram segmentation result to improve the classification effect of ICTCALS segmentation method. By using KNN categorization algorithm and Naive Bayes text categorization method, it proved this way worked well on FuDan university corpus. And it also analyzed the reason why the method was relatively noneffective on the Sogou laboratory corpus through the test.
