摘要: 微博逐渐成为舆论传播的重要载体,网络舆情中的意见领袖在舆情传播过程中发挥着推动作用,挖掘微博中的意见领袖对于管理社交网络舆情十分必要。综合考虑微博用户在网络中的转发评论等行为,构建微博用户“转发-评论”双层网络,通过引入用户交互行为的影响力贡献因子以及权重因子挖掘用户的影响力,提出基于Hits改进算法构建微博用户影响力评估算法。实验结果表明,该模型的F-score综合指标得分优于PageRank算法、Hits算法,能够更加准确地识别微博社区话题中的意见领袖,有效计算微博用户的实际影响力,更加准确有效地识别出微博社区某一话题中的意见领袖,为社交网络治理及网络舆情管理等方面提供参考。

Abstract: Microblog has gradually become an important carrier of public opinion communication. The opinion leaders in online public opinion play a driving role in the process of public opinion communication. It is necessary to explore the opinion leaders in microblog for the management of social network public opinion. Considering microblog users' behaviors such as forwarding comments in the network, a two-layer network of microblog users' “forwarding comments”is constructed. By introducing the influence contribution factor and weight factor of users' interaction behavior to mine users' influence, a microblog users' influence evaluation algorithm based on Hits improved algorithm is proposed. The experimental results show that the F-score comprehensive index score of this model is better than PageRank algorithm and Hits algorithm. It can more accurately identify opinion leaders in microblogging community topics, effectively calculate the actual influence of microblogging users, and more accurately and effectively identify opinion leaders in a certain topic of microblogging community, which can provide reference for research on opinion leaders mining in social networks.

Key words: opinion leaders, comment network, forwarding network, Hits algorithm
