| 摘 要： | 为了模拟信息在微博环境中的传播情况,根据微博用户行为(发布、关注、转发和评论等)和微博内容,提出一种融合用户行为和内容的微博用户影响力算法。通过对微博用户行为的分析,得到行为因子数据,进而计算出用户影响力的权值。利用微博用户内容建立词共现矩阵,继而运用狄利克雷分配(LDA)模型进行潜在主题分布的识别,通过KL(Kullback Leibler)散度的方法得到用户之间的相似性,最后结合用户影响力权值,得到用户的影响力。实验表明,此算法较为有效。

| Abstract: | . In order to simulate the propagation of information in microblog environment, a microblog user influence algorithm based on user behavior(post, follow, forward and comment)and content is presented. Behavior factor data can be obtained through the analysis of the behavior of microblog user, and then the user influence weight can be calculated. The word co-occurrence matrix is established using the microblog content, and then LDA(Latent Dirichlet Allocation) is used to identify the potential topic distribution. KL (Kullback Leibler) divergence is applied to obtain the similarity between users, the user influence is finally acquired based on use influence weight. Experiments show the effectiveness of this algorithm. |
