The final day at AoIR 2019 begins for me with a panel on social media bots, and the first speakers are Felix Münch and Ben Thies who present a paper that I have also contributed to; the slides are below. Social bots have become quite prominent in media coverage of social media in recent times, with particular focus on platforms like Twitter, but it is difficult to assess just how prevalent they are on such platforms, partly also because it is difficult to get a sense of the make-up of larger social media populations.
