Understanding the Roots of Radicalisation on Twitter

In an increasingly digital world, identifying signs of online extremism sits at the top of the priority list for counter-extremist agencies. Researchers and governments are investing in the creation of advanced information technologies to identify and counter extremism through intelligent large-scale analysis of online data. However, to the best of our knowledge, these technologies are neither based on, nor do they take advantage of, the existing theories and studies of radicalisation. In this paper we propose a computational approach for detecting and predicting the radicalisation influence a user is exposed to, grounded on the notion of ’roots of radicalisation’ from social science models. This approach has been applied to analyse and compare the radicalisation level of 112 pro-ISIS vs.112 “general" Twitter users. Our results show the effectiveness of our proposed algorithms in detecting and predicting radicalisation influence, obtaining up to 0.9 F-1 measure for detection and between 0.7 and 0.8 precision for prediction. While this is an initial attempt towards the effective combination of social and computational perspectives, more work is needed to bridge these disciplines, and to build on their strengths to target the problem of online radicalisation

Contextual Semantics for Radicalisation Detection on Twitter

Much research aims to detect online radical content mainly using radicalisation glossaries, i.e., by looking for terms and expressions associated with religion, war, offensive language, etc. However, such crude methods are highly inaccurate towards content that uses radicalisation terminology to simply report on current events, to share harmless religious rhetoric, or even to counter extremism. Language is complex and the context in which particular terms are used should not be disregarded. In this paper, we propose an approach for building a representation of the semantic context of the terms that are linked to radicalised rhetoric. We use this approach to analyse over 114K tweets that contain radicalisation-terms (around 17K posted by pro-ISIS users, and 97k posted by “general” Twitter users). We report on how the contextual information differs for the same radicalisation terms in the two datasets, which indicate that contextual semantics can help to better discriminate radical content from content that only uses radical terminology.The classifiers we built to test this hypothesis outperform those that disregard contextual informatio

Jihadi terrorism and the radicalisation challenge: European and American experiences

Osama bin Laden’s demise in May 2011 marked only the symbolic end of an era. By the time of his killing, he no longer represented the Robin Hood icon that once stirred global fascination. Ten years after the 11 September 2001 attacks, jihadi terrorism has largely lost its juggernaut luster. It now mostly resembles a patchwork of self-radicalising local groups with international contacts but without any central organisational design - akin to the radical left terrorism of the 1970s and the anarchist fin-de-siècle terrorism. This volume addresses two issues that remain largely unexplored in contemporary terrorism studies. It rehabilitates the historical and comparative analysis as a way to grasp the essence of terrorism, including its jihadi strand. Crucial similarities with earlier forms of radicalisation and terrorism abound and differences appear generally not fundamental. Likewise, the very concept of radicalisation is seldom questioned anymore. Nevertheless it often lacks conceptual clarity and empirical validation. Once considered a quintessential European phenomenon, the United States too experiences how some of its own citizens radicalise into terrorist violence. This collective work compares radicalisation in both continents and the strategies aimed at de-radicalisation. But it also assesses if the concept merits its reputation as the holy grail of terrorism studies

Critical Reflections on De-Radicalisation in Indonesia

Since 9/11 western and non-western governments have implemented counter-counter terrorism and de-radicalisation programs to “inoculate Muslim populations” and de-radicalise those deemed as radicalised through securitization and “moderate Islam”. The Indonesian government and civil society organizations have attempted to address radicalisation by setting up counter-radicalisation and de-radicalisation programs. This paper will critically reflect on the Indonesian de-radicalisation programs. It will first critically discuss the terms radicalisation and de-radicalisation. Then critically assess the Indonesian de-radicalisation programs. In the final section, the author suggests that Indonesia needs to introduce humanitarian activities to make the de-radicalisation programs more effective and overcome labelling and stigmatization.  

Addressing Radicalisation into the Classroom - A New Approach to Teacher and Pupil Learning

This article examines one response to the UK Governments directive that radicalisation and extremism should be tackled in all UK secondary schools. The small scale study, which is set in the broader literature of teaching often difficult PHSE topics to young people in secondary school and also the use of simulations as tools for learning in the classroom, analyses the responses of teachers to being trained with and using ‘Zak’ a bespoke research based simulation on the radicalisation process. An analysis of the teacher’s’ responses indicated that it was recognised that the principales of adults manipulating children, whether for sexual gratification or radicalisation, are considered to be very important topics for staff working with young people in school settings to address. It was also recognised as to be a flexible learning tool which enabled various pathways to be explored with young people in lessons to explore and raise issues regarding many aspects of e- safety, not just radicalisation. Additionally, the teachers remarked that the social media ‘Facebook’ format of the simulation was appreciated by the young people and this appeal resulted in their immersion with it as a teaching aid. Also of significance was how the ‘Zak’ package was delivered into schools with the staff reporting that the inter-professional training delivered by specialist police trainers and the accompanying materials enhanced the learning and confidence of the teachers on this multi-faceted and complex topic

Exploring the pathway from radicalisation to disengagement : comparison of dissonances experienced by a Jihadi foreign fighter and a right-wing extremist

The aim of our article is to analyse the disengagement process of a Swiss returnee from Syria and the emergence of dissonances during his involvement with the Islamic State (IS) and to compare this evolution to the pathway of a right-wing extremist willing to leave the violent extremist group Blood & Honour. Although the contexts of these extremist groups are very different, a number of elements – as the ideology based on hate, the groups’ internal pressure and the affinity for violence – are quite similar. The disengagement process of both extremists is analysed by means of reconstructive methods and the theory of cognitive dissonance (Festinger 1957), as well as by the current state of research on disengagement processes. This serves as a theoretical framework. The findings show that comparing their pathway to defection reveals a number of parallels: the experiences within the extremist groups, especially violent acts against group members, increased their dissonances and provided a trigger to an opening process and ultimately the attempt to opt out of the group

The Internet as Ideological Battleground

Recent global events that have brought to light the use of new technologies by terrorist groups have focused attention on the role of the internet in the radicalisation of vulnerable individuals and groups towards a violent extremism. In 2007, the case of Abdul Basheer, a law graduate in Singapore arrested for attempting to join the Taliban in Afghanistan drew attention to the use of the Internet as a source of inspiration and information for would be terrorists. More recently Sydney man Belal Khazaal became the first person to be convicted on the charge of making a document connected with assisting in a terrorist act after using material already available on the internet to develop his own publication The Rules of Jihad - Short Judicial Rulings and Organisational Instructions For Fighters And Mujahideen Against Infidels . Both cases point to the developing role of the Internet in the process of radicalisation and suggest that the Internet has become an important tactical tool in the terrorists’ repertoire. The role of the Internet in radicalisation and the extent to which it contributes to the process through which latent beliefs translate into violent actions is not fully understood. However, with the developing strand of terrorism studies that deals with the diffusion of intent as an integral component of counter terrorism efforts has come an understanding of terrorism as a battle of words and ideas. Nowhere is this more evident than on the internet

Jihadi video and auto-radicalisation: evidence from an exploratory YouTube study

Large amounts of jihadi video content on YouTube along with the vast array of relational data that can be gathered opens up innovative avenues for exploration of the support base for political violence. This exploratory study analyses the online supporters of jihad-promoting video content on YouTube, focusing on those posting and commenting upon martyr-promoting material from Iraq. Findings suggest that a majority are under 35 years of age and resident outside the region of the Middle East and North Africa (MENA) with the largest percentage of supporters located in the United States. Evidence to support the potential for online radicalisation is presented. Findings relating to newly formed virtual relationships involving a YouTube user with no apparent prior links to jihadists are discussed
