Magnanville, 13 June, 2016, around 8pm: policeman, Jean-Baptiste Salvaing has been stabbed to death outside his home. Forcing his way into the house, the attacker murders Jessica Schneider, who also worked for the police, by cutting her throat. The couple’s three year-old son is taken hostage by the killer, Larossi Abballa. Prior to a three hour stand-off with police negotiators, Aballa turns to social media to broadcast and justify his actions, dedicating them to his ‘Emir’ Abu Bakr Al-Baghdadi (Hume et al 2016). It is the first time a terrorist has used a live-streaming service in the midst of an attack. It is unlikely to be the last.

From Tweeter to Terrorist: Combatting Online Propaganda When Jihad Goes Viral

This Thesis contributes by proposing a method for identifying users believed to be at risk of radicalisation on social media, by utilising the social media networks of already radicalised individuals and a set of indicators derived from related work on radicalisation. In addition, this Thesis provides a new to the field, in-depth analysis of the personality traits of Twitter users at risk of radicalisation and how they may differ from ordinary users. The results show that the proposed data collection and annotation scheme is able to successfully identify individuals at risk of radicalisation, yielding an inter-annotator agreement, measured by Cohen’s Kappa, of 0.83. The analysis of the predicted personality traits shows that users at risk of radicalisation have common profiles for agreeableness and conscientiousness. When comparing the predicted traits to that of ordinary, non-radical Twitter users, the predictions show a marginal difference in distribution for agreeableness, openness, and conscientiousness, indicating a certain difference in personality between the two domains.

On this week’s blog, Professor Gabriel Weimann discusses his new book, published this month, From Theatres to Cyberspace: The Media and Terrorism which examines changing arenas of terrorist communication with a particular focus on emerging trends in the use of social media.
