| 摘 要： | 基于微博话题传播过程,提出了一种新的用户影响力分析方法.该方法首先结合微博信息传播机制,构建信息推送网和信息转发网;其次,基于上述网络建立话题传播网模型并提出CTDN构建算法;最后,以该模型为基础设计并实现了一种用户影响力排序算法TD-InfluenceRank,该算法在迭代计算用户影响力时通过考虑节点间的信息传播,使影响力更多地转移给关系密切的节点.实验结果表明,以TD-InfluenceRank算法为核心的用户影响力分析方法,能够有效提高话题传播中用户影响力分析的准确性.

| Abstract: | A new method of user influence analysis is proposed based on topic diffusion in microblog. It first constructes the information pushing network(IPN) and information forwarding network (IFN), based on which it builds the topic diffusion network(TDN) model and puts forward its constructing algorithm named CTDN. Based on TDN model, it also designs and implements a user influence ranking algorithm named TD Influence Rank, which considers the information dissemination between nodes when calculating user influence iteratively, so that more influence can be transferred to nodes with close ties. Experimental results indicate that the proposed method can improve effectively the accuracy of user influence analysis in topic diffusion. |
