Security informatics and intelligence computation plays a vital role in detecting and classifying terrorism contents in the web. Accurate web content classification using the computational intelligence and security informatics will increase the opportunities of the early detection of the potential terrorist activities. In this paper, we propose a modified frequency-based term weighting scheme for accurate ...

Dr Prucha discusses how to understand ‘Islamic State’ narratives by analysing their media output. The lecture was organised by VOX-Pol partner institute, International Centre for the Study of Radicalisation (ICSR) and held at King’s College London on 6 July 2015. It focuses on the symbiotic relationships between ideology, media content and strategic action, and on ...

The present study applies Social Learning (Differential Association) Theory to the explanation of political violence, focusing on exposure to extremist content through new social media (NSM) and controlling for key variables derived from rival theories. Data are gathered using (a) a paper-and-pencil study among high school students, and (b) a web survey targeting youths between ...

The purpose of this paper is to explore the role of interest groups in the formation of online echo chambers and to determine whether interest groups’ use of social media contributes to political polarization. This study used a content analysis of nearly 10,000 tweets (from 2009 to 2014) by the Brady Campaign to Prevent Gun ...

A fundamental idea from physics is that macroscopic transitions can occur as a result of an escalation in the correlated activity of a many-body system’s constituent particles. Here we apply this idea in an interdisciplinary setting, whereby the particles are individuals, their correlated activity involves online search activity surrounding the topics of social unrest, and ...

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 ...

Foreword-The standard media image of violent extremism may seem to be far from the ordinary work of the Swedish Media Council. While extremism is often described in dramatic terms of terrorism, attacks and riots, the Council’s work concerns more everyday things, such as age limits for cinema films and media awareness teaching in pre-school.

The capture of Mosul in the summer of 2014 by the self-styled ‘Islamic State’ appears today much more than a significant military event in the complex scenario of the Middle-East and in the tangled situation of Iraq and Syria. Close observers were not surprised. The establishment of the ‘Islamic State’ has characterized most of the ...

Research surrounding radicalization to and use of violence among extremist and terror groups has expanded over the last decade. There are still fundamental questions that must be addressed, particularly regarding the role of the Internet in radicalisation and recruitment as well as general technological skill within extremist groups. Few studies have considered this issue, especially ...

Lone-wolf terrorism is a threat to the security of modern society, as was tragically shown in Norway on July 22, 2011, when Anders Behring Breivik carried out two terrorist attacks that resulted in a total of 77 deaths. Since lone wolves are acting on their own, information about them cannot be collected using traditional police ...
