摘　　要：在舆情信息扩散网络结构基础上,从信息传播过程和扩散质量出发,综合考虑信息扩散广度、扩散速度、扩散深度三个评价维度,构建WSD-Rank扩散影响力度量模型,并对关键节点的分布规律及形成内因进行解析。实验结果表明,相比于粉丝数、转发/评论数、PR值等指标,该模型能直接、全面、准确的评价节点扩散影响力。Based on information diffusion network of public opinion, from the perspective of information transmission process and diffusion quality, this paper proposes a WSD-Rank influential evaluation model taking transmission width, speed and depth into consideration. Simultaneously, this paper analyzes the distribution law and the mechanism on the formation of key nodes. The results illustrate that new model is more direct, overall and accurate than models using indicators like followers, retweet-Num, reply-Num, and the pagerank.
