Center node: "the rise of jihadist propaganda on social networks"
  Abstract: Using a dataset of over 1.9 million messages posted on Twitter by about 25,000 ISIS sympathizers, we explore how ISIS makes use of social media to spread its propaganda and recruit militants from the Arab world and across the globe. By distinguishing between violence-driven, theological, and sectarian content, we trace the connection between online rhetoric and key events on the ground. To the best of our knowledge, ours is one of the first studies to focus on Arabic content, while most literature focuses on English content. Our findings yield new important insights about how social media is used by radical militant groups to target the Arab-speaking world, and reveal important patterns in their propaganda efforts.
