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