What if a single model could recognize an author's writing style no matter what language they wrote in? 🌍✍️ Our new #EMNLP2025 paper explores multilingual authorship representation, showing how training across 36 languages can sharpen stylistic signals and reduce topic bias.

Lot's of exciting work on linguistic style this year at #EMNLP2025 #EMNLP! Including work on machine-text detection, authorship representation and more

📣 with an open call to everyone to add style work that's missing

I have a new blog post about the so-called “tokenizer-free” approach to language modeling and why it’s not tokenizer-free at all. I also talk about why people hate tokenizers so much!

I successfully defended my PhD in Dutch fashion and required a PhD certificate in Latin. Thank you to the amazing people that got me here, a.o. @dongng.bsky.social and the ones I blur here.

Come join next Wednesday if you want to rant about society's love-hate relationship with LLMs!

one of the other entrances was closed off yesterday, increasing my commute from front door to office by another 10 minutes

Is this the Dutch budget cuts or does utrecht uni really not want me to come to the office? My highlight is the door that has been broken for weeks, with the only change being a laminated piece of paper saying I should enter uni maze through two other buildings.

Utrecht is back from #ACL2025! We had a blast.

I should have posted this before but here are some papers from people in our group that were presented at ACL.

I'm sadly not at #ACL2025, but the work on tokenization seem to continue to explode. Here are the tokenization related papers I could find, in no particular order. Let me know if I missed any.

Since people at #ACL2025 are very interested in tokenization, a reminder to join the discussion on discord set up by @mcognetta.bsky.social

Anyone tried the kiss the cook lunch place at #ACL2025?

I think accepted

I will present our #ACL2025 paper Tokenization is Sensitive to Language Variation in the poster session after Tuesday's keynote, 10.30 - 12.00 in Hall 4/5

@philipwitti.bsky.social will be presenting our paper "Tokenisation is NP-Complete" at #ACL2025 😁 Come to the language modelling 2 session (Wednesday morning, 9h~10h30) to learn more about how challenging tokenisation can be!

We are presenting this paper at #ACL2025 😁 Find us at poster session 4 (Wednesday morning, 11h~12h30) to learn more about tokenisation bias!

Im at #ACL2025 this week.

Happy to chat about measuring linguistic style, data diversity, creating synthetic data for analyzing (L)LMs, authorship attribution, paraphrases and tokenizers.

Let’s chat if you’re around

I love it.

I'll be attending ACL 2025 in Vienna! Looking forward to seeing people there!😊🇦🇹 We are going to present 'LLMs instead of Human Judges? A Large Scale Empirical Study across 20 NLP Evaluation Tasks' aclanthology.org/2025.acl-sho... #acl2025 #acl2025nlp

My fault for liking to prepare early in our last minute, deadline-driven community ...
