基于微博社交网络的信息传播分析

Analysis of Information Propagation in Social Networks

微博作为重要的社交媒体,越来越受到人们的重视。同传统的网络媒体相比,微博的信息传播呈现出数据量大、及时、快速等特点。主要研究微博信息传播树的分析技术,提出了两种微博信息传播树的生成算法:基于转发关系的微博信息传播树的生成算法和一种快速的微博信息传播树的生成算法。通过实验,对这两种算法的性能进行了对比,并分析了传播树的节点分布情况。

A growing number of people are paying attention to the microblog, which is an important tool in social media. Comparing with conventional network media, the information propagation on mieroblog presents some new features such as the big volume of data, rapidity, and timeliness. This paper mainly discusses the methods to analyze information propagation trees, and puts forward two algorithms to generate the trees： a generating algorithm based on reposting relations, and a fast generating algorithm. By experiments, the paper compares the performance of the two algorithms and analyzes the distribution of nodes in the propagation trees.
