Abstract:
In order to improve precise rate and recall rate of Chinese text classifier, a improve bagging algorithm – attribute bagging is used in this paper. Document is represented by vector space model and Information Gain is used to select term features. Re-sampling attributes are used to get multiple training sets and the kNN is selected as individual classifier. The classifier result is attained by voting. Experiments show that the attribute bagging gets lower errors and better performance than bagging and kNN in Chinese text categorization.
