The Call for Papers for #INLG2026 is out! 🗓️ Submit by July 15 (AoE) 💍 ARR commit by August 5 🆕 Squibs welcomed (raising an issue without needing to solve it) 🆕 Non-archival track for work in progress ——— 📍Utrecht, NL — Oct 17–21, 2026, right before EMNLP 2026.inlgmeeting.org/calls.html

New paper w/ UK AISI: Millions of people now use AI to help them write and communicate. In three experiments (14k participants, 3m+ human ratings) we show that AI writing assistance systematically distorts writer personas – their perceived beliefs, personality, and identity. 🧵

A dream come true. A conference in a train museum. What will the breaks be like? Choo Choo! 🚂🚂

Would you realize if the book you were reading was AI? What if it was humanized to remove AI-speak? We find that even without using stylistic cues (e.g., word choice or sentence structure) narrative choices alone give AI fiction away!

Patients ask LLMs medical questions — but how they phrase it matters more than it should. Our new preprint explores how different phrasings of patient health questions can lead to inconsistent conclusions, even with the same evidence. [1/6] Full Paper: arxiv.org/abs/2604.05051

📢 The workshop on Insights from negative results will be back at EMNLP'26! Your most-insightful failures can be submitted in 4 pages by June 25. It's also possible to commit short papers reviewed through ARR. insights-workshop.github.io/2026/cfp

Yay. Finally a conference next to my house! Hope to see many of the #NLProc #NLP community there 🤗

Survey-style tests developed for humans may not predict how LLMs actually behave. Our #EACL2026 paper shows they can even be misleading when measuring racism and sexism! Check out the paper 👇🏼

🥁🥁🥁 Newly out from us today in Science Advances: “Biased AI Writing Assistants Shift Users’ Attitudes on Societal Issues”. Large Language Models are providing users with autocomplete writing suggestions on many platforms. Could these suggestions shift users’ own attitudes? (spoiler: YES) (1/7)

Can LLMs figure out who you are from your anonymous posts? From a handful of comments, LLMs can infer where you live, what you do, and your interests; then search for you on the web. New 📄 w/ @SimonLermenAI, @joshua_swans, @AerniMichael, Nicholas Carlini, @florian_tramer 🧵

our paper on data mixing for LMs is out! while building Olmo 3, we saw gaps between data mixing literature and real practice 🐠choosing proxy size, # runs, sampling, regression, constraints.. 🐟data shifts during LM dev: can we reuse past experiments? Olmix tackles them all!

If you're attending #EMNLP2025, we'll be presenting virtually in Gather Session 1 on Nov 5 at 4pm PT. Come say hello! w/ the wonderful: @mellymeldubs.bsky.social Anna Preus, @mariaa.bsky.social Paper: arxiv.org/abs/2510.16713 Code/Data: github.com/darthbhyrava/wisp Dash: poetry.darthbhyrava.com

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. 👇🧵

New opinion paper out with Esther Ploeger (Aalborg University): We Need to Measure Data Diversity in NLP — Better and Broader at #EMNLP2025 (main) aclanthology.org/2025.emnlp-m...

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

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 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

The #ACL2025 #ACL2025NLP feed is up and running! It matches both hashtags and any posts from or mentions of @aclmeeting.bsky.social Pin it to your home 📌 and enjoy! bsky.app/profile/did:...

Who's presenting on subjectivity in annotation (human label variation, learning from disagreement, perspectivism) at #ACL2025? papers by e.g. @liweijiang.bsky.social @tiancheng.bsky.social @gabriellalapesa.bsky.social @romanklinger.de keynote @verenarieser.bsky.social link to full list below ⤵️

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

How come the @aclmeeting.bsky.social underline page was set to release July 20 last Friday and now promises access only on the 24th? Access to papers and videos remains evasive less than a week before the conference.

Do LLMs represent the people they're supposed simulate or provide personalized assistance to? We review the current literature in our #ACL2025 Findings paper and investigating what researchers conclude about the demographic representativeness of LLMs: osf.io/preprints/so... 1/

#ic2s2 I’ll be talking about this paper in one hour in Vingen 1+2!

#ic2s2 I’ll have a poster (#21) today on 𝐭𝐡𝐞 𝐢𝐦𝐩𝐚𝐜𝐭 𝐨𝐟 𝐠𝐞𝐧𝐞𝐫𝐚𝐭𝐢𝐯𝐞 𝐀𝐈 𝐨𝐧 𝐬𝐨𝐜𝐢𝐚𝐥 𝐦𝐞𝐝𝐢𝐚 ✌🏼

Join my talk on #ChildObjectification on TikTok at #IC2S2 today at 2:30 PM (📍 Social Good & Ethics). I built classification models to detect objectifying language and found: 10% of comments refer to appearance, 3% are objectifying. Models struggle with this task, with #RoBERTa outperforming GPT-4.

Wanna do some authorship attribution? Chances are what tokenizer you use matters. Tokenization is Sensitive to Language Variation, probably, more investigation necessary... 📄 ACL Findings paper: arxiv.org/pdf/2502.15343 🧑‍🏫 @dongng.bsky.social @davidjurgens.bsky.social and myself See you at ACL!

I'm at #ICML2025 this week in Vancouver. My co-authors and I are presenting two posters at the Tokenization Workshop on Friday tokenization-workshop.github.io. The first is on how much data is useful in training a tokenizer arxiv.org/abs/2502.20273.

How can we praise a technology when it is problematic for a large portion of our society? What does it say about the value of being a woman? If it's okay that this injury will happen but we going to bring it on the market anyway. My interview @newsweek.com & Marni Rose McFall tinyurl.com/ye22xda6

I'll be at ICML next week for the Tokenization Workshop @tokshop.bsky.social presenting two papers: "Evaluating Morphological Alignment of Tokenizers in 70 Languages" and "BPE Stays on SCRIPT: Structured Encoding for Robust Multilingual Pretokenization". Check out the paper threads below!

🚨 NEW WORKSHOP ALERT 🚨 We're thrilled to announce the first-ever Tokenization Workshop (TokShop) at #ICML2025 @icmlconf.bsky.social! 🎉 Submissions are open for work on tokenization across all areas of machine learning. 📅 Submission deadline: May 30, 2025 🔗 tokenization-workshop.github.io

PhD thesis submitted ✅

(1 ) *Insults Welsh language* (2) *Excitedly studies increased use of less than socially acceptable Welsh in Welsh participants*

What encoding error is this? It cant be the language I spent five years learning. Tokenizers, we stand no chance

📢 Closing this week! 📢 Supervised by @zeerak.bsky.social and starting Sept 2025, the project will examine the ethical implications of natural language processing. Apply now ▶️ edin.ac/40PAXEq

First step, identify all English variation and collect texts representing it. No biggie

It's great to read old methods sections. Pretend to be a lost shopper and secretly study language. Thanks Labov.

When I say my name, people start speaking French to me, although my French is basic. That also happens with AI systems. We wrote a whole paper on that, testing across models for presumed cultural identity based on names w/ Siddhesh Pawar @rnv.bsky.social @iaugenstein.bsky.social
