【摘要】 针对热点主题发现是在聚类算法的基础上实现的特点,将改进后的蚁群聚类算法引入到该研究中,同时提出类别关注度(CAD)的概念,以此来判定类别的热门程度并区分出热门类别和冷门类别,在此基础上抽取热点主题集。实验结果表明改进后的蚁群聚类算法对热点主题的发现有一定的效果,对其他仿生优化聚类算法的引入有借鉴意义。更多还原

【Abstract】 For the hot topics found is based on the clustering algorithm,this paper introduces the improved ant colony clustering algorithm,and raises Class Attention Degree(CAD) concept in order to determine the class of hot level and to distinguish popular categories as well as unpopular categories.Meanwhile,hot topic set is erxtracted on this basis.Experimental results show that the improved ant colony clustering algorithm has in certain effects to the hot topics found.更多还原
