New #ICML2026 paper: "On Effectiveness and Efficiency of Agentic Tool-calling and RL Training".

⚠️The methodology for measuring and improving tool-calling capabilities is fragile. We break down our analysis along two critical axes: (1) effectiveness; and (2) efficiency. 👇

Thanks @suchirsalhan for your seminar today, we loved hearing about your work on BabyLM!

I'm really excited to be delivering a seminar at @SheffieldNLP on Tuesday about my research on Small and Human-Scale Language Modeling! Thanks @_joestacey_, @_gucciiiii, Marco Valentino and @nikaletras for the invite!

[Xi Wang @wangxieric]

Today, in our @SheffieldNLP seminar series, we welcome Sean MacAvaney @macavaney from @TerrierTeam at University of Glasgow to give a talk entitled "Re-thinking Re-ranking".

[Constantinos Karouzos @ckarouzos]

Thrilled to see such a fantastic breakdown of our latest paper on output diversity collapse in post-training (with @Xingwei__Tan, @nikaletras, @SheffieldNLP)! 🚀

@neural_avb did a phenomenal job summarizing our work. Check it out below! 👇

Thanks very much to @sandropezzelle for your brilliant seminar about whether language processing in LLMs reflects human cognitive mechanisms.

[Nikos Aletras @nikaletras]

When we adapt LLMs to other languages using unlabeled target language data, they tend to lose their core instruction-following and reasoning abilities.

🚨 New #ACL2026 paper w/ @_gucciiiii, T. Morishita & @AlineVillav on how to mitigate this catastrophic forgetting 👇

[Nikos Aletras @nikaletras]

Our heart @SheffieldNLP will always be with *ACL, but we've also started getting serious about IR. Great to see our group's efforts in bridging #NLProc & search reflected so clearly in #SIGIR2026.

Special shout out to @wangxieric, @drmarkstevenson et al for leading this 👇

[Nikos Aletras @nikaletras]

LLMs are great at outputting step-by-step reasoning, but is that text actually driving their conclusions, or is it just post-hoc rationalisation? How can we improve the faithfulness of LLM reasoning?

My talk at the #EACL2016 FEVER wrkshp aimed to probe a dialogue on this 🧵👇

[Joe Stacey @_joestacey_]

Excited to share my first postdoc paper with @SheffieldNLP ! 🤩

In this work we argue that supervised uncertainty quantification (UQ) needs better evaluation

Congrats to @tylerl404 on passing his #PhD #viva on Assessing Phonetically and Phonologically Motivated Language Understanding. Thanks to supervisors Prof @chenghua_lin and Prof Rob Gaizauskas and viva examiners Dr @bjoernross (Edinburgh) and Dr @zhengyuan_nlp (Sheffield)!

[Sheffield NLP @SheffieldNLP]

We’re excited to share our latest papers accepted at @aclmeeting, @SIGIRConf, and beyond 🎉

From LLM reasoning and evaluation to multilingual NLP and fact-checking, there’s a lot we’ve been working on!
