We describe an innovative approach to social media analysis, combining corpus linguists and statistical methods to measure the resonance of Daesh's propaganda to a sample population (Eqypt). The findings from this research effort demonstrate that: (1) Daesh's messaging is measurable and distinct from other Salafi groups, such as the Egyptian Muslim Brotherhood; (2) while Daesh’s messaging generally do not resonate with Egyptians, its uptake increased in Upper Egypt and the Sinai regions during 2014; and (3) this method can be applied more broadly to measure the spread of violent extremist messaging across regional populations over time.
