Presenting this today at #ACL2025NLP!

Come to Board 26 in Hall 5X to talk about the relationship between community notes and fact-checking and the future of content moderation 🔎

If you are attending #ACL2025, come and check out our cool poster on Wednesday at 11 am!

(Oh yeah, I forgot to announce that the paper got accepted to the main proceedings of #ACL2025, oops)

CopeNLU will give five paper presentations and one invited talk at #ACL2025NLP this week ⤵️

🚨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

Show Me the Work: Fact-Checkers' Requirements for Explainable Automated Fact-Checking The pervasiveness of large language models and generative AI in online media has amplified the need for effective automated fact-checking to assist fact-checkers in tackling the increasing volume and ...

We did interviews with N=10 fact-checkers:

not sure if it's what you're looking for as it's HCI (we tried to highlight direct implications for NLP/ML research though!) 😇

Fact-checking agencies have come under intense scrutiny in recent months regarding their role in combating misinformation on social media.

Check our new work on making natural language explanations more faithful to a model’s reasoning. We combine GNNs + highlight explanations to improve faithfulness!

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! 💫🇩🇰

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

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