The man, the myth, the legend Thomas Jänich presenting another excellent Glasgow IR Group paper: "Fair Exposure Allocation using Generative Query Expansion" at this year's ECIR2025 #IR4GOOD track (work w/ graham mcdonald and Iadh Ounis)

The last remaining members of the group at the closing of the #ir4good track and the #ecir2025 workshops. As we bid farewell to the charming and warm Lucca, it’s time to start new journeys including heading back to the sunny and green Glasgow!

🚨 New Pre-Print! We show that in-context learning can steer LLM rankers to satisfy multiple objectives at once, relevance and fairness/diversity, without any parameter updates. Work done jointly with Nilanjan Sinhababu from IIT Kharagpur and Debasis Ganguly. 🧵 Below!

Full details in our paper. I'd love to discuss broader applications of this work in Padua at #SIGIR2025 in July, so reach out! In the meantime, have a read! ➡️ arxiv.org/abs/2505.17736

🚨 New Pre-Print! You've just added your 600th model to your negative mining pool and filtered all false negatives. Does any of this even matter when we can apply distillation? In this work with Debasis Ganguly and Sean MacAvaney, we explore data selection in modern ranking. 🧵 Below
