探索流式社交媒体数据变化对社会网络分析的影响

Exploring the effect of streamed social media data variations on social network analysis

Derek Weber, Mehwish Nasim, Lewis Mitchell, Lucia Falzon

摘要:

为了研究在线社交网络(OSN)活动对现实世界离线事件的影响,研究人员需要访问OSN数据,其可靠性对社会网络分析具有特殊意义。这不仅关系到任何收集的数据集的完整性,而且关系到从这些数据集构建有意义的社会和信息网络。在这个多学科的研究中,我们考虑的问题,从OSN数据构建传统的社交网络,然后提出了几个测量案例研究,显示在收集的OSN数据的变化如何影响社会网络分析。为此,我们开发了一个系统的COM的方法,我们应用于五对并行数据集收集从Twitter的四个案例研究。我们发现,使用不同工具收集的几个数据集存在相当大的差异,这些差异会显著改变后续分析的结果。我们的研究结果为计划收集在线数据流以推断社交网络的研究人员提供了一套指导方针。

英文摘要:

To study the effects of Online Social Network (OSN) activity on real-world offline events, researchers need access to OSN data, the reliability of which has particular implications for social network analysis. This relates not only to the completeness of any collected dataset, but also to constructing meaningful social and information networks from them. In this multidisciplinary study, we consider the question of constructing traditional social networks from OSN data and then present several measurement case studies showing how variations in collected OSN data affects social network analyses. To this end we developed a systematic com parison methodology, which we applied to five pairs of parallel datasets collected from Twitter in four case studies. We found considerable differences in several of the datasets collected with different tools and that these variations significantly alter the results of subsequent analyses. Our results lead to a set of guidelines for researchers planning to collect online data streams to infer social networks.
