Social media is a modern person’s digital voice to project and engage with new ideas and mobilise communities—a power shared with extremists. Given the societal risks of unvetted content-moderating algorithms for Extremism, Radicalisation, and Hate speech (ERH) detection, responsible software engineering must understand the who, what, when, where, and why such models are necessary to protect user safety and free expression. Hence, we propose and examine the unique research field of ERH context…

Detecting Potential Warning Behaviors of Ideological Radicalization in an Alt-Right Subreddit

This work uses a variety of text analysis methods to investigate the behavioral patterns of a radical right-wing community on Reddit over a 6-month period until right before it was banned for violation of Reddit terms of service and finds that this community showed aggregated behavioral patterns that aligned with past literature on warning behaviors of individual extremists in online environments.

Positing the problem: enhancing classification of extremist web content through textual analysis

Advances in techniques for classifying data collected by the Terrorism and Extremism Network Extractor (TENE) webcrawler are reported on, indicating that the use of the data enrichment through application of Posit analysis affords a greater degree of match between automatic and manual classification than previously attained.
