At @aclmeeting? Today (Monday, 28.07) at the 11:00 poster session, I'll present my final PhD paper: "TabVer: Tabular Fact Verification with Natural Logic". Joint work with the amazing @vlachos_nlp. Drop by to say hi :) Paper link📚:
arxiv.org
Fact verification on tabular evidence incentivises the use of symbolic reasoning models where a logical form is constructed (e.g. a LISP-style program), providing greater verifiability than fully...

@pietro_lesci is finishing his PhD soon, and on the job market :) so hire him if you want someone who thinks outside the box!
This lead author (@pietro_lesci) has the most creative NLP papers. He adapts methods typically used for observational studies and the results are always so cool

A string may get 17 times less probability if tokenised as two symbols (e.g., ⟨he, llo⟩) than as one (e.g., ⟨hello⟩)—by an LM trained from scratch in each situation! Our #acl2025nlp paper proposes an observational method to estimate this causal effect! Longer thread soon!

🔥 We teach LLMs to say how confident they are on-the-fly during long-form generation. 🤩No sampling. No slow post-hoc methods. Not limited to short-form QA! ‼️Just output confidence in a single decoding pass. ✅Better calibration! 🚀 20× faster runtime. arXiv:2505.23912 👇
