Our new paper in #PNAS (bit.ly/4fcWfma) presents a surprising finding—when words change meaning, older speakers rapidly adopt the new usage; inter-generational differences are often minor. w/ Michelle Yang, ‪@sivareddyg.bsky.social‬ , @msonderegger.bsky.social‬ and @dallascard.bsky.social‬👇(1/12)

Huge congratulations to Dr. @vernadankers.bsky.social for passing her viva today! 🥳🎓 It's truly been an honour sharing the PhD journey with you. I wasn’t ready for the void your sudden departure left (in the office and in my life!). Your new colleagues are lucky to have you! 🥺🥰

A blizzard is raging through Montreal when your friend says “Looks like Florida out there!” Humans easily interpret irony, while LLMs struggle with it. We propose a 𝘳𝘩𝘦𝘵𝘰𝘳𝘪𝘤𝘢𝘭-𝘴𝘵𝘳𝘢𝘵𝘦𝘨𝘺-𝘢𝘸𝘢𝘳𝘦 probabilistic framework as a solution. Paper: arxiv.org/abs/2506.09301 to appear @ #ACL2025 (Main)
