The ever-increasing use of the internet by terrorist groups as a platform for the dissemination of radical, violent ideologies is well documented. The internet has, in this way, become a breeding ground for potential lone-wolf terrorists; that is, individuals who commit acts of terror inspired by the ideological rhetoric emitted by terrorist organizations. These individuals are characterized by their lack of formal affiliation with terror organizations, making them difficult to intercept with traditional intelligence techniques. The radicalization of individuals on the internet poses a considerable threat to law enforcement and national security officials. This new medium of radicalization, however, also presents new opportunities for the interdiction of lone wolf terrorism. This dissertation is an account of the development and evaluation of an information technology (IT) framework for detecting potentially radicalized individuals on social media sites and Web fora. Unifying Collective Action Framing Theory (CAFT) and a radicalization model of lone wolf terrorism, this dissertation analyzes a corpus of propaganda documents produced by V several, radically different, terror organizations. This analysis provides the building blocks to define a knowledge model of terrorist ideological framing that is implemented as a Semantic Web Ontology. Using several techniques for ontology guided information extraction, the resultant ontology can be accurately processed from textual data sources. This dissertation subsequently defines several techniques that leverage the populated ontological representation for automatically identifying individuals who are potentially radicalized to one or more terrorist ideologies based on their postings on social media and other Web fora. The dissertation also discusses how the ontology can be queried using intuitive structured query languages to infer triggering events in the news. The prototype system is evaluated in the context of classification and is shown to provide state of the art results. The main outputs of this research are (1) an ontological model of terrorist ideologies (2) an information extraction framework capable of identifying and extracting terrorist ideologies from text, (3) a classification methodology for classifying Web content as resonating the ideology of one or more terrorist groups and (4) a methodology for rapidly identifying news content of relevance to one or more terrorist groups

The case of a civil society actor on Twitter entering a securitized discourse on terrorism illustrates the transformative theoretical potential that emerges from new forms of communication online. Through a qualitative analysis of tweets from the Average Mohamed profile, the potential to change a negative narrative of violent extremism operating within a securitised discourse of Islamic terrorism, is discussed in an online context. The arguments forming from this analysis offers a new approach to studying online counter narratives by linking a theoretical framework of securitisation and de-securitisation to recent political efforts Countering Violent Extremism (CVE) and Preventing Violent Extremism (PVE). Through the inclusion of a civil society Twitter account as an illustrative case, this paper explores how social media can challenge existing assumptions of who can be a de-securitising actor within security theory by blurring the lines between political and societal sectors in a securitised threat from Islamic terrorism. If and how a civil society actor can loosen the dichotomous discursive relationship between Self/Other relations within a contemporary discourse on terrorism becomes relevant for a theoretical discussion by presenting an argument suggesting that online CVE polices are more effective within the sphere of ‘normal’ politics rather than within the realm of securitization. This theoretical perspective offers an analytical framework including a wide range of actors involved in counter narratives policies which is useful for further CVE research.

„Inspire“ ist ein hochprofessionell gestaltetes Magazin, das bis zu viermal im Jahr von AlQaida im Internet publiziert wird. Das Magazin wird in englischer Sprache veröffentlicht und enthält neben Bombenbauanleitungen im Stile des Do-It-Yourself Trends auch Artikel über die Unterdrückung von Muslimen, Koraninterpretationen oder Erfahrungsberichte aus dem Leben von sogenannten Gotteskriegern. In der vorliegenden Studie wird das Magazin aus einer sozialkonstruktivistischen und wissenssoziologischen Perspektive heraus analysiert, um den Inhalt von „Inspire“ auf Deutungsrahmen hin zu untersuchen. Mit dem Methodenmix aus semantischer Netzwerkanalyse und qualitativer Bild- und Textanalyse wird das Datenmaterial deskriptiv sowie qualitativ-rekonstruktiv erschlossen. Am Ende der Arbeit steht die Rekonstruktion der im „Inspire Magazine“ abgebildeten Deutungsrahmen und ihrer Zusammensetzung zu einem extremistischen Weltbild. Die Bestandteile des Weltbildes wurden in acht Dimensionen unterteilt, sodass dezidierte Aussagen über Zielgruppe und Mobilisierungsmechanismen möglich wurden. Darüber hinaus konnte theoretisch fundiert herausgearbeitet werden, wie das Weltbild konstruiert wird, nämlich über das Freund-Feind Schema, Mechanismen der Unterdrückung, das Bilden einer kollektiven Identität und das Nutzen der Vulnerabilität von Adoleszenz. Diese vier Ansatzpunkte bilden eine mögliche Erklärung für Selbstradikalisierungsprozesse über das Internet.

Acute crisis events ranging from natural disasters to terrorist incidents now tend to generate an almost immediate response from social media users. This is especially pronounced on Twitter, due to that platform’s specific affordances as a particularly open and real-time medium. While analyses of such events have increased over recent years, we still understand relatively little about the way in which audiovisual materials relating to such crises are circulated and what they contribute to processes of witnessing. This is important, however, in an increasingly visual age when audiovisual material tends to be more widely viewed and shared than plain-text updates, and thus has a greater potential to influence viewers’ interpretations of an event. To address this gap in our understanding, this article investigates the distribution dynamics of audiovisual content on Twitter in the immediate aftermath of terror attacks in Paris and Brussels. Results point to the importance of broadening conceptualisations of conflict-related visuals and the ongoing relevance of affective content in such material. Furthermore, this article argues that contexts of time and space are crucial to consider, as is the role that individual actors – both human and non-human – play in disseminating such content.

Terrorism is a highly irregular form of crime where multiple factors combine to create circumstances that are unique to each case of involvement, or attempted involvement, in terrorist violence. Yet, there are commonalities in the way in which efforts to become involved unfold as processes, reflected as sequential developments where different forces combine to create conditions where individuals seek to plan acts of violence. The best way to frame this involvement is through analytical approaches that highlight these procedural dimensions but are equally sensitive to the nuances of each case. Analysing pre-arrest media usage of convicted terrorists, this paper focuses on the ways in which belief pathways and operational pathways interact in five distinct cases of terrorist involvement in the UK in what are termed ‘process narratives’.

This article argues that the Islamic State’s cyber jihad, fully launched in 2014, is currently undergoing a regression that is demonstrated by the weakening of its quality, coverage and effectiveness. Comparing the character, major forms and popularity of Daesh’s releases from 2014 and 2015 with its most up-to-date productions, one can notice evident alterations signaling the long-awaited, but limited as yet, impairment of the “Caliphate’s” propaganda machine, composed of such specialized cells as the Amaq News Agency, al-Furqan Media, al-I’tisam Foundation, al-Himmah Library, or the al-Hayat Media Center. This transition is caused by a multitude of factors, with both offline and online origins.
