Come join us at the poster session at ICTIR 2025 to discuss: - Axioms for Retrieval-Augmented Generation #merker_2025b" target="_blank" rel="nofollow noopener">webis.de/publications.h… - Learning Effective Representations for Retrieval Using Self-Distillation with Adaptive Relevance Margins #gienapp_2025b" target="_blank" rel="nofollow noopener">webis.de/publications.h…

Honored to win the ICTIR Best Paper Honorable Mention Award for "Axioms for Retrieval-Augmented Generation"! Our new axioms are integrated with ir_axioms: github.com/webis-de/ir_ax… Nice to see axiomatic IR gaining momentum.

Go to stall 091 if you want to check out the poster of this @ir_glasgow work by @DanielTian97 called "Am I on the Right Track?" #SIGIR2025 (done w/t @JinyuanF, @debforit, @mengzaiqiao and @craig_macdonald)

It's a busy day for @DanielTian97! After his earlier presentation, he's now presenting his poster that studies the search behaviour of agentic rag using QPP. *Go to poster 91 and have a chat! * @ir_glasgow #SIGIR2025

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. 📄 #gienapp_2025a" target="_blank" rel="nofollow noopener">webis.de/publications.h…

🏆 Our paper "GINGER: Grounded Information Nugget-Based Generation of Responses", co-authored with @krisztianbalog, won the Best Short Paper Award at #SIGIR2025! Grateful to the community for the recognition 🙌 Check out the code & poster here: github.com/iai-group/ging…

Want to know how to make bi-encoders more than 3x faster with a new backbone encoder model? Check out our talk on the Token-Independent Text Encoder (TITE) #SIGIR2025 in the efficiency track. It pools vectors within the model to improve efficiency dl.acm.org/doi/10.1145/37…

Huge congratulations to @macavaney on receiving the prestigious ACM SIGIR Early Career Researcher Award in the research category! This well-deserved recognition highlights the excellence & impact of his work in the IR community 👏🎉#sigir2025 Cc @GlasgowCS @UofGlasgow @ACMSIGIR

@LukasGienapp presents "The Viability of Crowdsourcing for RAG Evaluation" at #SIGIR2025 The paper is available at: #gienapp_2025a" target="_blank" rel="nofollow noopener">webis.de/publications.h…

Now it’s @MrParryParry presenting the reproducibility efforts of a large team of researchers in relation to the shelf life of test collections #sigir2025

A comprehensive and nicely delivered tutorial by @macavaney et al. on learned sparse retrieval methods and their applications across various tasks. Slides and other materials are available via the link shown in the last image. #SIGIR2025

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 github.com/webis-de/light…

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.

Today, Harry Scells @hscells from University of Tübingen is giving an #IRTalk entitled "Quantifying and Applying Green IR". Details: samoa.dcs.gla.ac.uk/events/viewtal… @GlasgowCS @ir_glasgow

At 15:00 on 28th April, Harry Scells @hscells from University of Tübingen will give an #IRTalk entitled "Quantifying and Applying Green IR". Details: samoa.dcs.gla.ac.uk/events/viewtal… @GlasgowCS @ir_glasgow

Yesterday I presented our #ECIR2025 paper "An Investigation of Prompt Variations for Zero-shot LLM-based Rankers", with @shuoqi_sun @ShengyaoZhuang @dylan_wangs. Yes, it was in a church! Slides at ielab.io/files/guido-20… and paper at arxiv.org/abs/2406.14117

Now it's workshop time here at #ECIR2025! @andrew_parry is kicking things off at the QPP++ workshop presenting his work (w/ @H1iReimer, Simon Ruth, @maik_froebe, @hscells) on Corpora Performance Prediction. @ir_glasgow @glasgowcs
