一种改进的微博用户影响力评价算法

Improved User Influence Evaluation Algorithm of Microblog

微博用户的影响力研究是微博社区研究的一个热点。以新浪微博为研究对象,构建了用户活跃度和历史关注度两个评价指标,引入微博传播能力这一因子,提出了一种基于传统的PageRank算法的改进算法(user influence rank)模型,通过实验与传统算法进行对比,验证了该算法的有效性和准确性。

The Influence of microblog users is a hotspot in community research. Based on Sina mi- croblog platform, through two indicators of activity of users and historical attention, a user influence assessment system is constructed, the factor of the spread ability of the microblogs is introduced, the idea of traditional PageRank algorithm is used to improve a new influence ranking algorithm （User Influence Rank）. Compared through experiments with traditional algorithm, the proposed algorithm is effective.
