Co-authors: @Yminglai @Vikas_NLP_UA @msurd — thank you! See you in Suzhou, Nov 4–9. 🙏 #EMNLP2025 (6/6)

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/s…

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

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

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

Today (4/25, 11am EST)! In our final CS Colloquium of this series, @msurd shares how combining symbolic rules with neural models leads to more explainable information extraction. #NLP #ExplainableAI @KCSciences_UML @uarizona see details👉 ow.ly/fZL250BGU4M

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

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.🧵

Our new paper in Findings of NAACL 2025, with Vlad Negru, @robert_nlp, @CameliaLemnaru, 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

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 opinionated about the software stack. The software stack I personally use changes every few weeks. There are many good alternatives to these choices, and if you pick a preferred software stack and become familiar with its components, you’ll be able to develop more quickly. But as an illustration, here’s my current default: - Python with FastAPI for building web-hosted APIs: I develop primarily in Python, so that’s a natural choice for me. If you’re a JavaScript/TypeScript developer, you’ll likely make a different choice. I’ve found FastAPI really easy to use and scalable for deploying web services (APIs) hosted in Python. - Uvicorn to run the backend application server (to execute code and serve web pages) for local testing on my laptop. - If deploying on the cloud, then either Heroku for small apps or AWS Elastic Beanstalk for larger ones (disclosure: I serve on Amazon’s board of directors): There are many services for deploying jobs, including HuggingFace Spaces, Railway, Google’s Firebase, Vercel, and others. Many of these work fine, and becoming familiar with just 1 or 2 will simplify your development process. - MongoDB for NoSQL database: While traditional SQL databases are amazing feats of engineering that result in highly efficient and reliable data storage, the need to define the database structure (or schema) slows down prototyping. If you really need speed and ease of implementation, then dumping most of your data into a NoSQL (unstructured or semi-structured) database such as MongoDB lets you write code quickly and sort out later exactly what you want to do with the data. This is sometimes called schema-on-write, as opposed to schema-on-read. Mind you, if an application goes to scaled production, there are many use cases where a more structured SQL database is significantly more reliable and scalable. - OpenAI’s o1 and Anthropic’s Claude 3.5 Sonnet for coding assistance, often by prompting directly (when operating at the conceptual/design level). Also occasionally Cursor (when operating at the code level). I hope never to have to code again without AI assistance! Claude 3.5 Sonnet is widely regarded as one of the best coding models. And o1 is incredible at planning and building more complex software modules, but you do have to learn to prompt it differently. On top of all this, of course, I use many AI tools to manage agentic workflows, data ingestion, retrieval augmented generation, and so on. DeepLearning.AI and our wonderful partners offer courses on many of these tools. My personal software stack continues to evolve regularly. Components enter or fall out of my default stack every few weeks as I learn new ways to do things. So please don’t feel obliged to use the components I do, but perhaps some of them can be a helpful starting point if you are still deciding what to use. Interestingly, I have found most LLMs not very good at recommending a software stack. I suspect their training sets include too much “hype” on specific choices, so I don’t fully trust them to tell me what to use. And if you can be opinionated and give your LLM directions on the software stack you want it to build on, I think you’ll get better results. A lot of the software stack is still maturing, and I think many of these components will continue to improve. With my stack, I regularly build prototypes in hours that, without AI assistance, would have taken me days or longer. I hope you, too, will have fun building many prototypes!

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

Sunsets in Arizona are something else (no Photoshop):

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.

Announcement #1: our call for papers is up! 🎉 colmweb.org/cfp.html And excited to announce the COLM 2025 program chairs @yoavartzi @eunsolc @RanjayKrishna and @AdtRaghunathan

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
