The growing penetration of online social networks (OSNs) has emerged as a strong operational tool for spreading online radicalization by adding intensity and acceleration to the operations of radical groups. The efficiency of ways and methods proposed to measure the dynamics of radicalization are limited by the availability of models for modeling the intricacies of human dynamics and heterogeneous time varying interactions. Most of the developed algorithms and tools mainly focus on the static network structures and tend to ignore the “origin” of a new radical idea or propagation of a “weak” topic which might find its relevance in the security domain later on with the passage of time. In this article we propose a mathematical model for measuring dynamic propagation of radicalization in OSNs using Discrete Time Markov Chains by discretizing the continuous time domain. We also discuss our experimental results obtained through the information network of Twitter. The approach presented here is scalable and can easily be extended for modeling diffusion of general topics in OSNs.

Radicalisation has gained some unusual prominence in the academic
circles; maintaining a generic existence not only in the political sector. And with the
advent of the Information Communication Technology (ICT), radicalisation has
begun to have some virtual dimension even in the remotest of human communities.
This study seeks to mobilise a universal awareness on the collective urgency to oppose
Online Radicalisation (a radicalisation that happens through the internet) due to its
propensity to engendering conflicts. It also aims at identifying the principal cause of
online radicalisation and steer a clear course for a practical reversal in the systems of
online radicalisation.

Radical milieus have been described as specific social environ¬ments whose culture, narratives, and symbols shape both individuals and groups, and the social networks and relationships out of which those individuals and groups develop and emerge. Researcher Peter Waldmann and his co-authors attribute distinct and independent qualities to these environments, portraying them as social entities in their own right, that is, a collective of people sharing certain perspectives and a unitary identity: a “subculture” or a “community.” This does not mean that conflict is absent between any given radical milieu and the violent extremist or terrorist group(s) that emerges from within it. Milieus have their own interests that lead them not just to interact with, but oftentimes to criticise and sometimes even confront their violent offshoots. Perhaps most importantly, Waldmann’s conception of radical milieus appears not merely to have social relationships as a core characteristic, but necessitates, implicitly or explicitly, face-to-face interaction amongst the members of any given milieu.

Social media has become the milieu of choice to radicalize young impressionable minds by terrorist organizations such as al Qaeda and the Islamic State. While a plethora of research exists on the recruitment and propaganda efforts by terrorist organizations there is limited number of quantitative studies that observe the relationship of gender and the involvement in online radical milieus. This current research will build upon prior studies through the comparative analysis of 750 unique Twitter accounts supporting the IS and the affiliates of al-Qaeda that were non-randomly sampled between January and September of 2015. The research aimed to address the questions of: 1) whether women that are involved in pro-jihadist communities on Twitter post substantively different amounts of content than men, 2) whether women that are involved in pro-jihadist communities on Twitter post substantively different content than their male counterparts and, 3) whether the gender disparity in level and type of involvement on Twitter differ amongst the supporters of different jihadist organizations. This study found that, while pro-jihadist communities on Twitter continue to be dominated by male participation, female supporters of the IS are more active and post more violent content than women that support any other organization. The intragroup differences found amongst the female supporters suggests that group ideology, recruitment and
propaganda strategies play a role in the level of involvement of women in radical milieus.

Following America’s “War on Terror,” al-Qaeda and its affiliates became highly decentralized in terms of organizational and media operations. Though mass media outlets continue to play a significant role in drawing attention to al-Qaeda’s transnational campaign, Salafi Jihadists have recently begun to rely on new media for purposes of legitimization and promotion. The Internet serves as a suitable platform for these groups’ media objectives since it is inherently anonymous and absent of censorship. Most importantly, the Internet facilitates al-Qaeda in reaching a global audience, which is made evident by the growing amount of Salafi Jihadist media that is translated or created for English speakers. The latter change may seem paradoxical to the groups’ anti-Western sentiment, but it underscores an important shift in al-Qaeda’s recruitment strategies. The proliferation of English content promoting the Salafi Jihadist cause may imply that al- Qaeda is shifting its attention towards the Muslim diaspora in the West with the intent to recruit, radicalize, and promote acts of terror.
This study analyzed a variety of online publications that were disseminated by al- Qaeda and similar Salafi Jihadist groups. The sample included speech and video transcripts, digital magazines, and articles that were analyzed for the intent to radicalize readers through the employment of Albert Bandura’s eight mechanisms of moral disengagement. The analysis provided substantial support for the latter claim, indicating that many of the digital publications disseminated by Salafi Jihadist groups are intended to both radicalize and recruit readers through the promotion of moral disengagement.

The increasing complexity and emergence of Web 2.0 applications have paved way for threats arising out of the use of social networks by cyber extremists (Radical groups). Radicalization (also called cyber extremism and cyber hate propaganda) is a growing concern to the society and also of great pertinence to governments & law enforcement agencies all across the world. Further, the dynamism of these groups adds another level of complexity in the domain, as with time, one may witness a change in members of the group and hence has motivated many researchers towards this field. This proposal presents an investigative data mining approach for detecting the dynamic behavior of these radical groups in online social networks by textual analysis of the messages posted by the members of these groups along with the application of techniques used in social network analysis. Some of the preliminary results obtained through partial implementation of the approach are also discussed.
