Concepts of a Pyramidal Model for Assessing Internet-based Terrorist Propaganda

The Internet provides a borderless environment to interact and communicate with each other, not only for legitimate purposes but also to spread radicalization, propaganda, brainwashing and for online recruitment. Due to the large amount of daily data generated, and especially the different levels of radicalization of the users, make it difficult to define countermeasures against such phenomenon. In this context, the paper introduces the concepts of using a pyramidal model, to support the detection of terrorist propaganda, as well as its categorization by allocating it to different level of radicalization. After the description of the model, the main advantages in terms of intervention prioritization and application of targeted countermeasures are discussed.
