一种新的微博热点话题传播关键博主发现

New Identification Method on Critical Bloggers of Micro blog Hot Topics Diffusion

在微博热点话题的传播过程中,部分微博用户在传播网络中担当着非常重要的角色,能够促进信息更快和更广地传播。针对微博核心用户,首先提出了采用HITS算法的改进算法来识别微博热点话题传播过程中出现的关键博主;其次还构建了微博热点话题传播的关键节点网络;最后,通过实验分析验证了算法的有效性。研究结果表明:经过改进的WeiboHITS算法可以有效地识别微博传播网络的关键节点,关键节点的合理有效布局有助于构建规模更大的传播网络。

In Micro Blog hot topic propagation, Part of the Micro Blog users occupy a crucial position in the Micro Blog network, they make information spread faster and wider. Based on this kind of core users, an improved HITS al- gorithm was proposed to identify the critical bloggers of Micro Blog hot topic propagation. Then we built up Micro Blog topic network transmission of critical nodes. At last, through the experiment, an analysis verified the validity of the algorithm. The research results show that： the improved Weibo-HITS algorithm can effectively identify the key nodes. Reasonable and effective key node layout helps build a broader scale communication networks.
