Decoding Antisemitism

An AI-driven Study on Hate Speech & Imagery Online

The three-year pilot project “Decoding Antisemitism”, carried out by a research team at the Centre for Research on Antisemitism (ZfA, TU Berlin) in collaboration with King’s College London, examines antisemitism in the comments sections of leading media within the political mainstream.

The fifth Discourse Report analyses online comments in reaction to statements of rapper Kanye West, to 2022 FIFA World Cup in Qatar, and to the Israeli legislative elections. In addition, it presents an evaluation of existing tools for the automated detection of hate speech and presents an innovative approach based on transfer learning.

The fourth Discourse Report investigates two major international events: the Russian invasion of Ukraine and an eruption of terrorist violence in Israel in early 2022. It also examines four national case studies which illustrate the adaptability of contemporary anti-Jewish prejudice.

The third Discourse Report sheds light on the differences and similarities of antisemitic responses – particularly Holocaust distortion – to two discourse events in France and Germany: the anti-health pass demonstrations and the prosecution of former concentration camp personnel.

The second Discourse Report presents the definitional basis of our analyses and for the first time provides comprehensive insights into our corpus analyses relating to Great Britain, France and Germany – with a focus on the escalation phase in May 2021, the vaccine rollout in Israel and three independent case studies.
The first Discourse Report provides insight into the methodological approaches and the nature of antisemitic hate speech in selected online discourse spaces in Germany and the UK.
