The evolution of the ISIS' language: a quantitative analysis of the language of the first year of Dabiq magazine

In this article we investigate the evolution of ISIS by analysing the text contained in Dabiq, the official ISIS’ internet magazine in English. Specifically, we used a computerized text analysis pro-gram LIWC (Linguistic Inquiry and Word Count) to investigate the evolution of the language of the first 11 Issues of Dabiq.

Scholars suggested that the majority of newly recruited jihadists prefer ISIS to other jihadist groups (Karmon, 2015; Klausen, 2015; Peresin, 2015; Peresin & Cervone, 2015; Turner, 2015)and journalists reported that existing members of al-Qaeda even abandoned the group to join ISIS (Dilanian, 2015; Miller, 2014). Moreover, a 2015 report from the International Centre for the Study of Radicalisation and Political Violence based at London King’s College stated that the number of jihadist foreign fighters in Syria
