Abstract

© 2018 IEEE. The paper presents an Alert Mechanism for analysing and detecting National Security threats using Social Media posts as the primary source of information. This mechanism is meant to be an early warning system that can identify situations where a critical mass of individuals feel attracted towards a disruptive cause, based on emotions and Human Security aspects, which may lead to societal tipping points. Comprehensive experiments on real-world events related to disruptive and non-disruptive cases demonstrate both the robustness and effectiveness of the proposed mechanism.
