🎉 We are incredibly excited to announce the Keynote Speakers for #EMNLP2026: Pascale Fung, Graham Neubig, and Anna Korhonen! See you in October in Budapest! 🔗 2026.emnlp.org/program/keyn...

For SHROOM-Visions, the hidden angle was benchmark obsolescence. Making the SHEEP dataset to answer that was a lot of work, but also a lot of fun 🐑
