Talk, Mechanisms of Domination?: State Sponsored Information and Media Ecosystems at 119th American Political Science Association Annual Meeting, Los Angeles, CA
In this work, we study the most prominent disinformation narratives being touted by the Russian government to English-speaking audiences. To do this we perform topic analysis using the large-language model MPNet on articles published by nine different Russian disinformation websites and the new Russian “fact-checking” website waronfakes.com. We then map Reddit comments to the topics being promoted by these disinformation websites.

Talk, University of Oxford, Oxford Internet Institute, Oxford, UK
In this work, firstly utilizing daily scrapes of 3,074 news websites (both mainstream and misinformation), the large-language model MPNet, and DP-Means clustering, we build a system to automatically isolate and analyze the narratives being spread within online ecosystems. Secondly, to understand the impact of AI-Written content, we present one of the first large-scale studies of the prevalence of AI-written articles within online news media.
