Abstract
A growing body of research suggests that an individual's willingness to fight and die for groups is rooted in the fusion of personal and group identities, especially when the group is threatened, violence is condoned, and the group's enemies are dehumanised or demonised. Here we consider whether the language used by extremists can help with early detection of these risk factors associated with violent extremism. We applied a new fusion-based linguistic violence risk assessment framework to a range of far-right extremist online groups from across the violence spectrum. We conducted an R-based NLP analysis to produce a Violence Risk Index, integrating statistically significant linguistic markers of terrorist manifestos as opposed to non-violent communiqués into one weighted risk assessment score for each group. The language-based violence risk scores for the far-right extremist groups were then compared to those of non-extremist control groups. We complemented our quantitative NLP analysis with qualitative insights that contextualise the violence markers detected in each group. Our results show that the fusion markers combined with several other variables identified across the different online datasets are indeed indicative of the real-world violence level associated with the relevant groups, pointing to new ways of detecting and preventing violent terrorism.
期刊介绍:
Terrorism and Political Violence advances scholarship on a broad range of issues associated with terrorism and political violence, including subjects such as: the political meaning of terrorist activity, violence by rebels and by states, the links between political violence and organized crime, protest, rebellion, revolution, the influence of social networks, and the impact on human rights. The journal draws upon many disciplines and theoretical perspectives as well as comparative approaches to provide some of the most groundbreaking work in a field that has hitherto lacked rigour. Terrorism and Political Violence features symposia and edited volumes to cover an important topic in depth. Subjects have included: terrorism and public policy; religion and violence; political parties and terrorism; technology and terrorism; and right-wing terrorism. The journal is essential reading for all academics, decision-makers, and security specialists concerned with understanding political violence.
