At #EMNLP2026 LUHME today, I spoke about Explainable & Robust Automatic Fact Checking. AI-assisted fact-checking needs more than accurate verdicts: it needs evidence, faithful explanations, and effective uncertainty communication. isabelleaugenstein.github.io/slides/2026_... #NLProc #XAI

Good morning from Budapest! ☀️ CopeNLU is at #EMNLP2026 with papers on knowledge, culture & bias in LLMs, among others, plus a LUHME keynote. Come say hi to @iaugenstein.bsky.social @apepa.bsky.social @sekh-copenlu.bsky.social @saravera.bsky.social, Siddhesh, Dawar & Philip! 📍 Where to find us ⤵️

I'm in Europe, and next week I'll be in Malmö (for #AIES until Weds) & Copenhagen speaking at the Pioneer Center for AI on Thurs www.aicentre.dk/events/20261... Thank you @gretawarren.bsky.social & @iaugenstein.bsky.social for hosting me! If you are around and want to chat/catch up, do reach out!

🚨 Last chance -- closing in two days: call for a postdoc position on mechanistic interpretability and AI reasoning in our @copenlu.bsky.social lab ⤵️ @aicentre.dk #NLProc #XAI #academicjobs

People use LLMs to answer subjective, culturally situated questions. Most benchmarks ask whether the answer is correct, but they overlook the framing features (eg, insider positioning) 📄 New #EMNLP'26 paper: "Not What, But How: A Communicative Audit of LLM Response Framing"

Our paper on measuring epistemic diversity in LLMs is accepted to #EMNLP2026! We find that diversity has improved, though LLM output is much less diverse than Web search, especially for non-English. Paper: arxiv.org/pdf/2510.04226 Code/data: github.com/dwright37/ll... #NLProc @copenlu.bsky.social

Excited to share that our work, "BiasGym: A Simple and Generalizable Framework for Analyzing and Removing Biases through Injection", was accepted at the EMNLP 2026 (Findings). 📄 Paper (Updated): arxiv.org/pdf/2508.08855 💻 Code: github.com/copenlu/Bias...

Excited to share that our work, "Multi-Step Knowledge Interaction Analysis via Rank-2 Subspace Disentanglement", was accepted at the EMNLP 2026 (Findings). Huge thanks to my amazing PhD supervisors: @iaugenstein.bsky.social, and @apepa.bsky.social! See you all in Budapest 🇭🇺!

How do people use images to spread misinformation online?🖼️ We developed a taxonomy, analysed 27k posts from X in 7 languages & found: 🔹Slanted framing of real images is more common than deepfakes and doctored images 🔹Vaccine misinfo borrows credibility via news screenshots arxiv.org/abs/2608.29681
