| 摘 要： | 对于中文文本分类问题，提出一种新的Bagging方法。这一方法以决策树C4.5算法为弱分类器，通过实例重取样获取多个训练集，将其结果按照投票规则进行合成，最终得到分类结果。实验证明，这种算法的准确率、查全率、F1值比C4.5、kNN和朴素贝叶斯分类器都高，具有更加优良的性能。

| Abstract: | Aiming at the problem of Chinese text classification,a new method of Bagging is developed.The decision tree C4.5 is selected as the weak classifier and multiple training sets are gained through re-sampling instance.Then,the outputs are combined by voting and the final classification results are obtained.The experimental results show that the classifier based on the C4.5Bagging gets higher precision,recall,F-measure and better performance than C4.5,kNN and Naive-Bayse. |
