How can explainable AI empower fact-checkers to tackle misinformation? 📰🤖

We interviewed fact-checkers & identified explanation needs & design implications for #NLP, #HCI, and #XAI.

Excited to present this work with

🚨New pre-print 🚨

News articles often convey different things in text vs. image. Recent work in computational framing analysis has analysed the article text but the corresponding images in those articles have been overlooked.
We propose multi-modal framing analysis of news: arxiv.org/abs/2503.20960

We did interviews with N=10 fact-checkers:

I'm extremely grateful to all the fact-checkers and journalists who volunteered to be interviewed and for the insightful conversations at #GlobalFact11 (see you at #GlobalFact12?)

Thanks too, to all @copenlu.bsky.social for providing such a welcoming and supportive research environment! 💫🇩🇰
