A presentation by Clément Bénesse, PhD and Martin Lestra, PhD (Opsci.ai). This event is part of the Digital Governance Research Colloquium hosted by the Centre for Digital Governance.
Informational chaos has become prominent on social networks. Content is produced in large volumes and circulates at high speed. This is an ideal environment for disinformation narratives to migrate through various platforms, cultures and languages. In order to better identify, dissect and counter disinformation, PROMPT rests on three main ideas: that rhetorics are central to narrative spread; that there is no magic wand to detect disinformation, but rather a number of features that can help the community to act; that AI, and LLMs in particular can be mobilised to conduct qualitative analysis at scale. PROMPT incorporates AI in a two-pronged innovative approach. First, by using a double-funnel that disentangles misinformative signals through a variety of filters, before aggregating relevant information for fact-checkers and others (OSINTers and activists, etc.). Second, and thanks to this specific architecture, by deploying what is called an "agentic pipeline" to automate relevant tasks while curbing associated costs (e.g compute). With this, PROMPT provides a multilingual and platform-agnostic tool for the community engaged in the fight against disinformation.
Clément Bénesse, PhD currently leads the research department at Opsci.ai. He holds a doctorate in mathematics from the University of Toulouse III, specializing in sensitivity analysis and algorithmic fairness. He was a post-doc at the computer science laboratory at the Université du Québec à Montréal (UQÀM) and the law laboratory at the University of Ottawa, developing expertise in responsible artificial intelligence. His research interests revolve around trustworthy AI – eXplainability, Algorithmic Fairness, Privacy, Finetuning... – and its usage for a better society, including Disinformation Detection and Alignment of LLMs to social values.
Martin Lestra, PhD coordinates the EU-funded PROMPT pilot project at Opsci.ai. He holds a PhD in political science from the European University Institute. He has led several international cooperation projects at the intersection between data and public policy at the OECD, the University of Toulouse III and in the private sector.
