| 摘 要： | 为减少一词多义现象及训练样本的类偏斜问题对分类性能的影响，提出一种基于语义网络社团划分的中文文本分类算法。通过维基百科知识库对文本特征词进行消歧，构建出训练语义复杂网络以表示文本间的语义关系，再次结合节点特性采用K-means算法对训练集进行社团划分以改善类偏斜问题，进而查找待分类文本的最相近社团并以此为基础进行文本分类。实验结果表明，本文所提出的中文文本分类算法是可行的，且具有较好的分类效果。

| Abstract: | In order to reduce the polysemy phenomenon and the influence of the category deflect problem of training samples, a Chinese text categorization method was proposed on community division of semantic network. Firstly, disambigurtion was in progress through Wikipedia knowledge base, the complex network of text is built in order to represent the semantic relations between training texts. Then, in order to improve the problem of category deflect, the training samples is partitioned by the method of K-means which combined with the synthetic characteristics of network nodes. Finally, the text classification based on the nearest community of testing text is found out according to the nearest community. Results of experiments show that the algorithm proposed by this paper is feasible and can improve the effect of its classification. |
