We just released "German Commons", the largest openly-licensed German text dataset for LLM training: 154B tokens with clear usage rights for research and commercial use. https://t.co/FWmDdd4p2j

Honored to win the ICTIR Best Paper Honorable Mention Award for "Axioms for Retrieval-Augmented Generation"!
Our new axioms are integrated with ir_axioms: https://t.co/T6i9S324Fh
Nice to see axiomatic IR gaining momentum.

Happy to share that our paper "The Viability of Crowdsourcing for RAG Evaluation" received the Best Paper Honourable Mention at #SIGIR2025! Very grateful to the community for recognizing our work on improving RAG evaluation.

Thank you @cadurosar for shout-out of Lightning IR in the LSR tutorial at #SIGIR2025

If you want to fine your own LSR models, check out our framework at https://t.co/X3Mm6MhmVO

[Maik Fröbe @maik_froebe]

Do not forget to participate in the #TREC2025 Tip-of-the-Tongue (ToT) Track :)

The corpus and baselines (with run files) are now available and easily accessible via the ir_datasets API and the HuggingFace Datasets API.

Our paper on self-distillation for training bi-encoders got accepted at #ICTIR2025! By exploiting pretrained encoder capabilities, our approach eliminates expensive teacher models and batch sampling while maintaining the same effectiveness.

Due to many requests, ReNeuIR @ #SIGIR2025 paper deadline has been extended to June 10!!!

[ReNeuIR Workshop @ ACM SIGIR 2026 @ReNeuIRWorkshop]

The fourth edition of ReNeuIR @ #SIGIR2025 is back!! Check https://t.co/cFaPXT7H7E to see what we have in mind this year! Paper submission deadline: May 20, 2025.

What an honor to receive both the best short paper award and the best paper honourable mention award at #ECIR2025. Thank you to all the co-authors @maik_froebe @hscells @ShengyaoZhuang @bevan_koopman @guidozuc @bennostein @martinpotthast @matthias_hagen 🥳

📢 Our paper "The Viability of Crowdsourcing for RAG Evaluation" has been accepted to #SIGIR2025 ! We compared how good humans and LLMs are at writing and judging RAG responses, assembling 1800+ responses across 3 styles, and 47K+ pairwise judgments in 7 quality dimensions. 🧵➡️

@DeepLcom After the recent update, it is possible anymore to resize the window to one-column layout. Why? This was the only viable way of working fast on small screens...

[Damiano Spina 🦋@damianospina.com @damiano10]

Not leaving quite yet, but I’m finding my Bluesky feed less noisy and more enjoyable.

@martinpotthast created a starter pack with some members of the IR community, which we hope it keeps growing!

ReNeuIR at #SIGIR2024: 61 systems evaluated within our shared task initiative. Submissions are still open!

[Maik Fröbe @maik_froebe]

Evaluating generative retrieval systems that directly return generated texts with references is an interesting research problem for the coming years. Now we have Niklas Deckers at #SIGIR2024 presenting perspectives on "Evaluating Generative Ad Hoc IR". https://t.co/3sACw1Ui9s

[Joel Mackenzie @joelmmackenzie]

On Thursday, we're running the #reneuir workshop at #sigir2024. The workshop will have two amazing keynote speakers (@ZhuyunDai and Qi Chen) as well as a number of original and invited talks, plus a shared poster session. Please come along!
