Postdoc @rug.nl with Arianna Bisazza. Interested in NLP, interpretability, syntax, language acquisition and typology.

I’m very happy to share that my latest paper on the 𝐚𝐜𝐪𝐮𝐢𝐬𝐢𝐭𝐢𝐨𝐧 𝐨𝐟 𝐯𝐞𝐫𝐛 𝐦𝐞𝐚𝐧𝐢𝐧𝐠, tested on models trained under CDL data vs ADL data , has been accepted for an 𝐨𝐫𝐚𝐥 𝐩𝐫𝐞𝐬𝐞𝐧𝐭𝐚𝐭𝐢𝐨𝐧 at the upcoming edition of 𝐂𝐨𝐠𝐒𝐜𝐢, which will take place at the end of July in Rio de Janeiro.💃

👀 Look what 🎅 has broght just before Christmas 🎁: a brand new Research Master in Natural Language Processing at @facultyofartsug.bsky.social @rug.nl Program: www.rug.nl/masters/natu... Applications (2026/2027) are open! Come and study with us (you will also learn why we have a 🐮 in our logo)

Natural Language Processing

How do you build Large Language Models? How do humans experience Natural Language Processing (NLP) applications in their daily lives? And how can we...

📢Out now in NEJLT!📢 In each of these sentences, a verb that doesn't usually encode motion is being used to convey that an object is moving to a destination. Given that these usages are rare, complex, and creative, we ask: Do LLMs understand what's going on in them? 🧵1/7

New work to appear @ TACL! Language models (LMs) are remarkably good at generating novel well-formed sentences, leading to claims that they have mastered grammar. Yet they often assign higher probability to ungrammatical strings than to grammatical strings. How can both things be true? 🧵👇

Screenshot of a figure with two panels, labeled (a) and (b). The caption reads: "Figure 1: (a) Illustration of messages (left) and strings (right) in toy domain. Blue = grammatical strings. Red = ungrammatical strings. (b) Surprisal (negative log probability) assigned to toy strings by GPT-2."

I'm in Suzhou to present our work on MultiBLiMP, Friday @ 11:45 in the Multilinguality session (A301)! Come check it out if your interested in multilingual linguistic evaluation of LLMs (there will be parse trees on the slides! There's still use for syntactic structure!) arxiv.org/abs/2504.02768

With only a week left for #EMNLP2025, we are happy to announce all the works we 🐮 will present 🥳 - come and say "hi" to our posters and presentations during the Main and the co-located events (*SEM and workshops) See you in Suzhou ✈️

🌍Introducing BabyBabelLM: A Multilingual Benchmark of Developmentally Plausible Training Data! LLMs learn from vastly more data than humans ever experience. BabyLM challenges this paradigm by focusing on developmentally plausible data We extend this effort to 45 new languages!

I'll be in Vienna only from tomorrow, but today my star PhD student Marianne is already presenting some of our work: BLIMP-NL, in which we create a large new dataset for syntactic evaluation of Dutch LLMs, and learn a lot about dataset creation, LLM evaluation and grammatical abilities on the way.

Marianne de Heer Kloots@mdhk.net · last yr.

Next week I’ll be in Vienna for my first *ACL conference! 🇦🇹✨ I will present our new BLiMP-NL dataset for evaluating language models on Dutch syntactic minimal pairs and human acceptability judgments ⬇️ 🗓️ Tuesday, July 29th, 16:00-17:30, Hall X4 / X5 (Austria Center Vienna)

The BLiMP-NL dataset consists of 84 Dutch minimal pair paradigms covering 22 syntactic phenomena, and comes with graded human acceptability ratings & self-paced reading times. 

An example minimal pair:
A. Ik bekijk de foto van mezelf in de kamer (I watch the photograph of myself in the room; grammatical)
B. Wij bekijken de foto van mezelf in de kamer (We watch the photograph of myself in the room; ungrammatical)

Differences in human acceptability ratings between sentences correlate with differences in model syntactic log-odds ratio scores.

Ik snap niet dat hier niet meer ophef over is: Het binnenhalen van Amerikaanse wetenschappers wordt betaalt door Nederlandse academici geen inflatiecorrectie op hun salaris te geven. 1/2
