ABSTRACT
In order to be able to prevent online radicalization phenomena, it is necessary to be familiar with the propaganda processes and describe a whole range of digital actions carried out by terrorist groups in cyberspace. The link between terrorism and the media has been known since the 19th century, but it’s the last decade that was particularly rich in terms of the Internet battle, and clearly the ISIS group has largely won the fight in the network.
If states want to resist and build tools for our next victories, it is necessary to develop a cross-disciplinary research approach in order to detect and characterize different types of terrorist discourse and then produce algorithms that would identify them and alert on their presence. Over the last three years, within the scope of a European project, PRACTICIES, several laboratories specializing in humanities and digital sciences worked together to produce models and technological tools related to the digital presence of the ISIS group. The chapter shows the result of a dialogue between the sociology, linguistics, communication sciences, computer engineering and artificial intelligence fields. The outcome has made it possible to produce a human–machine interaction model capable of reinforcing the instrumentation used by Internet companies, police and security services.
