本文首先提出主题本体树层次结构的主题结构模型,并研究了基于主题本体树的层次主题检测技术.在真实新闻数据上的仿真实验表明,该方法能从文本流中有效检测层次主题,实验表明三种测度中混合对称测度效果更好.
This paper puts forward the hierarchical structure tree theme ontology theme structure model,and based on the theme ontology tree level theme detection technology,and finally presents the simulation experiment.In the real news of data simulation experiment results show that this method can detect effectively flow from text hierarchical theme,in addition,three measure mixed symmetrical measure the effect is better.Finally,the research field is discussed.
