经纪人机器人:分析Twitter上高影响力事件期间的自动活动

Broker Bots: Analyzing automated activity during High Impact Events on Twitter

Sudip Mittal, Ponnurangam Kumaraguru

摘要:

Twitter现在是一个成熟和广泛流行的新闻媒体。无论是普通的玩笑还是对波士顿马拉松爆炸案、2014年2月美国冰暴等高影响力事件的讨论,人们使用Twitter来获取更新。Twitter机器人今天已经变得非常普遍和可接受。Twitter机器人为这些用户提供了一种在Twitter上执行某些任务的方法,这些任务既简单又结构重复。在高影响力事件期间,这些Twitter机器人往往提供时间关键和全面的信息。我们介绍了机器人如何参与讨论,并在高影响力的事件中增强它们。我们确定了2013年高影响事件中的机器人:波士顿爆炸,2014年2月美国冰暴,华盛顿海军基地枪击案,俄克拉荷马州龙卷风和飓风菲林。我们通过手动注释所有此类帐户来识别顶级推特用户中的机器人。然后,我们研究他们的活动,并提出许多重要的见解。我们确定了这些事件期间机器人对信息扩散的影响,以及它们如何倾向于从各种来源向不同用户聚合和代理信息。我们还分析了他们的推文,列出了在高影响事件期间机器人和非机器人(正常或人类帐户)之间的重要区别特征。我们还展示了机器人如何慢慢地从传统的基于API的帖子转向IFTTT,dlvr.it等网络自动化平台。使用标准的机器学习,我们提出了一种方法来在高影响事件期间实时的识别机器人/非机器人。这项研究还通过比较2013年高影响事件的数据与2011年类似事件的数据,研究了机器人场景的变化。最后,我们还深入分析了2013年波士顿马拉松爆炸事件中活跃的Twitter机器人。

英文摘要:

Twitter is now an established and a widely popular news medium. Be it normal banter or a discussion on high impact events like Boston marathon blasts, February 2014 US Icestorm, etc., people use Twitter to get updates. Twitter bots have today become very common and acceptable. People are using them to get updates about emergencies like natural disasters, terrorist strikes, etc. Twitter bots provide these users a means to perform certain tasks on Twitter that are both simple and structurally repetitive. During high impact events these Twitter bots tend to provide time critical and comprehensive information. We present how bots participate in discussions and augment them during high impact events. We identify bots in high impact events for 2013: Boston blasts, February 2014 US Icestorm, Washington Navy Yard Shooting, Oklahoma tornado, and Cyclone Phailin. We identify bots among top tweeters by getting all such accounts manually annotated. We then study their activity and present many important insights. We determine the impact bots have on information diffusion during these events and how they tend to aggregate and broker information from various sources to different users. We also analyzed their tweets, list down important differentiating features between bots and non bots (normal or human accounts) during high impact events. We also show how bots are slowly moving away from traditional API based posts towards web automation platforms like IFTTT, dlvr.it, etc. Using standard machine learning, we proposed a methodology to identify bots/non bots in real time during high impact events. This study also looks into how the bot scenario has changed by comparing data from high impact events from 2013 with data from similar type of events from 2011. Lastly, we also go through an in-depth analysis of Twitter bots who were active during 2013 Boston Marathon Blast.
