Abstract
social media became a fertile soil for various threats, extremism, and
radicalization. This challenged policy-makers, researchers and
practitioners. Preventing such extreme activities from happening becomes
an ultimate priority at local and global scale. This paper introduces a
new intertwine between radicalization and natural language processing
capable of estimating the risk score of individuals based on their
social media activities. The system uses a hybridized ERG22+ and VERA-ER
model, which classifies individuals as high or low risk radicalization
profile. The developed system was tested and validated on the Video
Comments Threat Corpus dataset and Twitter pro-ISIS fanboys datasets
where it achieves 95.1% and 64.9% accuracy, respectively.
