Radicalisation processes take place in a field of tension between the actor and the outside world. External reactions and circumstances can have a supportive but also a rather negative and escalating effect on the dynamics of group development, depending on how they are perceived. Radical groups often react to circumstances in the outside world, incorporate them into their own discourse and provide their followers with a processed interpretation of them. This can be observed particularly well on social media. Within the scope of a thematic content analysis, we analysed how external circumstances were received within the community and what influence they had on the dynamics of the group Millatu Ibrahim.

Policymakers have invested considerable effort and research funding to understand the role of the Internet in radicalisation processes and attack planning. This includes approaches to identify radicalisation or “weak signals” for terrorist intentions in online behaviour. As a result, security authorities have become increasingly interested in approaches to computer science including Artificial Intelligence. Nevertheless, what results have research efforts thus far yielded? Can computer science prove useful? And what are the possibilities and limitations of automated tools?
