Come join us at the poster session at ICTIR 2025 to discuss:
- Axioms for Retrieval-Augmented Generation https://t.co/eDmCHt07fc
- Learning Effective Representations for Retrieval Using Self-Distillation with Adaptive Relevance Margins https://t.co/8gt8EAUpBQ

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.

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)

[Jack McKechnie @JackMcK1999]

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! *

🏆 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 🙌

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 https://t.co/M3gpeuaLlx

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

[Glasgow IR Group @ir_glasgow]

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 https://t.co/X3Mm6MhmVO

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.

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 https://t.co/mpC8zN0rHO and paper at https://t.co/R0L8S9RfQ5

[Jack McKechnie @JackMcK1999]

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.
