Recent research has shown a substantial active presence of bots in online social networks (OSNs). In this article, we perform a comparative analysis of the usage and impact of bots and humans on Twitter—one of the largest OSNs in the world. We collect a large-scale Twitter dataset and define various metrics based on tweet metadata. Using a human annotation task, we assign “bot” and “human” ground-truth labels to the dataset and compare the annotations against an online bot detection tool for evaluation. We then ask a series of questions to discern important behavioural characteristics of bots and humans using metrics within and among four popularity groups. From the comparative analysis, we draw clear differences and interesting similarities between the two entities.

Twitter 上机器人和人类的大规模行为分析

最近的研究表明,在线社交网络 (OSN) 中存在大量活跃的机器人。在本文中,我们对世界上最大的 OSN 之一的 Twitter 上的机器人和人类的使用和影响进行了比较分析。我们收集了一个大规模的 Twitter 数据集,并根据推文元数据定义了各种指标。使用人工注释任务,我们将“机器人”和“人类”真实标签分配给数据集,并将注释与在线机器人检测工具进行比较以进行评估。然后,我们提出一系列问题,以使用四个受欢迎群体内部和之间的指标来辨别机器人和人类的重要行为特征。从比较分析中,我们得出了两个实体之间的明显差异和有趣的相似之处。
