James P. Gleeson, Tomokatsu Onaga, Peter Fennell, James Cotter, Raymond Burke, David J. P. O'Sullivan

AI总结:

该研究通过分析Twitter上的信息级联,验证了分支过程假设的近似合理性,对比发现有限注意力模型优于独立级联模型,且分支过程解析结果与实证统计特征匹配良好,为社会信息传播研究提供了有效工具。

摘要:

本文对基于Twitter的信息级联开展了详细分析,证实分支过程假设近似成立。借助分支过程框架,研究对比了不同的智能体间传播模型,得出结论:有限注意力模型比更常用的独立级联(independent cascade)模型能更好地复现数据的相关特征。研究还表明,分支过程的既有及全新解析结果与实证信息级联的重要统计特征匹配度良好,由此证明分支过程描述对于理解社会信息传播具有重要作用。

英文摘要:

A detailed analysis of Twitter-based information cascades is performed, and it is demonstrated that branching process hypotheses are approximately satisfied. Using a branching process framework, models of agent-to-agent transmission are compared to conclude that a limited attention model better reproduces the relevant characteristics of the data than the more common independent cascade model. Existing and new analytical results for branching processes are shown to match well to the important statistical characteristics of the empirical information cascades, thus demonstrating the power of branching process descriptions for understanding social information spreading.
