We are in the heart of Tucson and one of 49 UNESCO Cities of Gastronomy. 1M people live in the Tucson metro area, and we are surrounded by saguaros and 4 mountain ranges. Saguaro National Park is in town. visittucson.org

Check out our new benchmark on Evaluating LMs as Synthetic Data Generators! Main findings: - LMs' ability to generate synthetic data varies - This is not necessarily correlated with problem solving ability - More data from cheaper models is often better than less from stronger

I just finished teaching an introduction to deep learning course based on our textbook. All content (book, slides, code) is available here: clulab.org/gentlenlp/

and it is like that with any sufficiently challenging NLP task. LLMs are way better than before, but not perfect, and cannot really be improved in an interesting way. frustrating. but we should focus on *other* opportunities they bring, not the old tasks in which we are stuck.

🚀 Registration for CLEF 2025 Labs is NOW OPEN! Don’t miss your chance to participate in this year’s CheckThat! Lab, where we tackle some of the most critical challenges in fact-checking and information verification. 🔥 Why Join CheckThat! Lab? This year, we bring you four

Over the break, I simplified the most common usage of our #nlproc library: clulab.org/processors/bas…

Using AI-assisted coding to build software prototypes is an important way to quickly explore many ideas and invent new things. In this and future posts, I’d like to share with you some best practices for prototyping simple web apps. This post will focus on one idea: being

Our new paper in Findings of NAACL 2025, with Vlad Negru, Robert Vacareanu, Camelia Lemnaru, and Rodica Potolea, proposes a new, softer take on Natural Logic, where alignment is generated through text morphing. This yields robust performance cross domain. arxiv.org/abs/2502.09567

We created SuperBPE🚀, a *superword* tokenizer that includes tokens spanning multiple words. When pretraining at 8B scale, SuperBPE models consistently outperform the BPE baseline on 30 downstream tasks (+8% MMLU), while also being 27% more efficient at inference time.🧵

I am truly humbled to receive this award. It represents everything I stand for. I consider it the apex of my career.

Today (4/25, 11am EST)! In our final CS Colloquium of this series, Mihai Surdeanu shares how combining symbolic rules with neural models leads to more explainable information extraction. #NLP #ExplainableAI Kennedy College of Sciences at UMass Lowell University of Arizona see details👉 ow.ly/fZL250BGU4M

This is actually a really solid context engineering template. Kudos, Anthropic

This is a good idea: 2025.emnlp.org/desk-rejection/

Now that school is starting for lots of folks, it's time for a new release of Speech and Language Processing! Jim and I added all sorts of material for the August 2025 release! With slides to match! Check it out here: web.stanford.edu/~jurafsky/slp3/

An important new EMNLP paper coming from our lab, with several nice and cool co-authors :)
