The paper describes a recently-created Twitter corpus of about 6,000 tweets, annotated for hate speech against immigrants, and developed to be a reference dataset for an automatic system of hate speech monitoring. The annotation scheme was therefore specifically designed to account for the multiplicity of factors that can contribute to the definition of a hate ...

Social media systems allow Internet users a congenial platform to freely express their thoughts and opinions. Although this property represents incredible and unique communication opportunities, it also brings along important challenges. Online hate speech is an archetypal example of such challenges. Despite its magnitude and scale, there is a significant gap in understanding the nature ...

Common approaches to text categorization essentially rely either on n-gram counts or on word embeddings. This presents important difficulties in highly dynamic or quickly-interacting environments, where the appearance of new words and/or varied misspellings is the norm. A paradigmatic example of this situation is abusive online behavior, with social networks and media platforms struggling to ...

However, the biggest threats might not originate in men’s groups’ activities. A big threat currently comes from Internet trolls’ responses to individuals who engage in hate‐provoked and hate‐provoking attacks on women as women. This ...

To address this gap, in-depth interviews were conducted with ten Canadian former right-wing extremists who were involved in ...

This article argues that similarities between jihadism and far-right radicalism are increasing, particularly with regard to the spectacularisation of violence. Spectacularisation means representing and performing violence in the form of a show, for instance through live-streaming, with a renewed emphasis on captivating symbols and much less attention paid to the ideological foundations on which the ...

The Islamic State of Iraq and ash-Sham (ISIS) continues to use social media as an essential element of its campaign to motivate support. On Twitter, ISIS’ unique ability to leverage unaffiliated sympathizers that simply retweet propaganda has been identified as a primary mechanism in their success in motivating both recruitment and “lone wolf” attacks. The ...

Reciprocal radicalisation is the theory that extremist organisations are connected and feed on one another’s rhetoric and actions to justify violent escalation. Recent empirical work has suggested that reciprocal radicalisation is a good deal more subtle than is often assumed, and is nuanced by organisational, social and political context. This study seeks to apply the ...

We present two studies of online ephemerality and anonymity based on the popular discussion board /b/ at 4chan.org: a website with over 7 million users that plays an influential role in Internet culture. Although researchers and practitioners often assume that user identity and data permanence are central tools in the design of online communities, we ...
