| Abstract: |
| This page designs a Chinese web categorization system,with the same feature weight,feature selection and categorizing algorithm,based on Word-Segment categorization system and N-Gram categorization system.The experiment demonstrates that being based on N-Gram categorization system has the same effect as being based on Word-Segment categorization system,which is more effective in some aspects. |
| Key words: chinese web categorization N-Gram word-segment KNN |
