摘要： 基于半监督概念聚类技术,提出一种改进的领域本体图中文文本分类算法。根据领域本体图结构模型,创建中文文本分类的本体学习框架,利用HowNet字典实现术语提取并建立中文术语-术语关系映射。依据术语间的权重连接关系,设计二分类关系的KLSeeker本体中文文本分类算法,并通过基于概念聚类的本体图半监督学习,实现中文文本的精确分类。实验结果表明,与基于非负张量分解的中文文本分类算法相比,该算法具有更高的分类精度。

Abstract: This paper proposes an improved Chinese text classification algorithm by Domain Ontology Graph(DOG)based on semi-supervised concept clustering.According to the DOG structure model,the ontology learning framework of Chinese classification is created,and then the HowNet dictionary is used to extract the word disambiguation,and then the Chinese term-term relationship mapping is established.Based on the weight connection between the terms of the binary classification relationship,here designs the KLSeeker ontology Chinese text classification algorithm.It realizes accurate classification of Chinese text through DOG semi-supervised learning.Experimental results show that the proposed algorithm has a higher classification accuracy compared with the Chinese text classification algorithm based on non-negative tensor decomposition ontology concepts.
