Excited to present at #CLEF2025 #Touché Lab (Session 2) shared task "Advertisement in RAG"🇪🇸! @webis.de 🗓️Sept 9 (Tue) ⏲️5:20PM (CEST) / 11:20AM (EST) 📍Florentino Sanz Room 🧠https://arxiv.org/abs/2507.00509 Join us for insights on #RAG + advertising!

Some exciting news! 🤗 After 3 amazing years at TREC, the Tip-of-the-Tongue (ToT) shared task will be a core task at NTCIR-19 in 2026. The new track will focus on tip-of-the-tongue information needs in English and East Asian languages. More details coming soon. See you all in Tokyo next year!

Gentle reminder 📢 All run submissions for the Tip-of-the-Tongue (ToT) Track are due next week Wednesday (Aug 27). More info: trec-tot.github.io/guidelines #TREC2025 #TRECToT #TREC2025ToT

This year's TREC Tip of the Tongue (ToT) track will be amazing! Based on our rigorous experiments on synthetic ToT query generation presented at #SIGIR2025, we extended the track to open domain ToT queries. We provide codes for baseline systems, and submissions are due by August 27th!

To Eun Kim just presented the work on "Tip of the Tongue Query Elicitation for Simulated Evaluation" at #SIGIR2025. The approach will be used in the #TREC2025 Tip-of-the-Tongue track, and we had some sweets at the poster :) The paper is available online: dl.acm.org/doi/10.1145/...

Hello TREC-ToTers! We have released the test queries for the TREC 2025 Tip-of-the-Tongue (TREC-ToT) Track. Please see the guidelines for more information: trec-tot.github.io/guidelines. Run submission deadline will tentatively be in August. #TREC2025 #TRECToT #TREC2025ToT Please spread the word!

❓How do LLMs respond to fair ranking in RAG? 🤩 See how fair ranking boosts downstream utility while promoting fairer attribution of cited sources. Catch our oral presentation at #ICTIR2025! #SIGIR2025 @841io.bsky.social

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. More details are available at: trec-tot.github.io/guidelines

🖋️ Curious how writing differs across (research) cultures? 🚩 Tired of “cultural” evals that don't consult people? We engaged with interdisciplinary researchers to identify & measure ✨cultural norms✨in scientific writing, and show that❗LLMs flatten them❗ 📜 arxiv.org/abs/2506.00784 [1/11]

Hello TREC-ToTers! 👋🏽 Excited to announce the release of TREC 2025 Tip-of-the-Tongue (TREC-ToT) Track guidelines: trec-tot.github.io/guidelines. We will release test queries in July and run submission deadline will be in August. #TREC2025 #TRECToT #TREC2025ToT Please register to participate:

Ever trusted a metric that works great on average, only for it to fail in your specific use case? In our #NAACL2025 paper (w/ @841io.bsky.social), we show why global evaluations are not enough and why context matters more than you think. 📄 aclanthology.org/2025.finding... #NLP #Evaluation (🧵1/9)

🚨New Breakthrough in Tip-of-the-Tongue (TOT) Retrieval Research! We address data limitations and offer a fresh evaluation method for these complex queries. Curious how TREC TOT track test queries are created? Check out this thread 🧵 and our paper 📄: arxiv.org/abs/2502.17776

Did you know? Gestures used to express universal concepts—like wishing for luck—vary DRAMATICALLY across cultures? 🤞means luck in US but deeply offensive in Vietnam 🚨 📣 We introduce MC-SIGNS, a test bed to evaluate how LLMs/VLMs/T2I handle such nonverbal behavior! 📜: arxiv.org/abs/2502.17710

Heading to #NeurIPS2024 to present our ‘Fair RAG’ paper at the #AFME2024 workshop! Let's talk about RAG, Information Retrieval, and Fairness. Honored that our paper was selected as one of the Top 5 Spotlight Papers! 🎉 Let’s connect and chat! Paper: arxiv.org/abs/2409.11598

Slides are up! I presented on "Presentation & Consumption in the context of REML" The full deck is here. There's a lot of gems if you're interested in this space! retrieval-enhanced-ml.github.io/sigir-ap2024...

Those who are attending #SIGIRAP2024, come by and learn how retrieval can enhance ML models!

Creating a 🦋 starter pack for people working in IR/RAG: go.bsky.app/88ULgwY I can’t seem to find everyone though, help definitely appreciated to fill this out (DM or comment)!

Mat is not on 🦋—posting on his behalf! It's time to revisit common assumptions in IR! Embeddings have improved drastically, but mainstream IR evals have stagnated since MSMARCO + BEIR. We ask: on private or tricky IR tasks, are rerankers better? Surely, reranking many docs is best?

Time for a starter pack on information retrieval: go.bsky.app/MXPJoTn

Hey all! I started a second starter pack with people who didn't make the first one, please let me know if you'd like to be added: go.bsky.app/JgneRQk

I'm keeping track of people at the CMU Language Technologies Institute here: go.bsky.app/NhTwCVb. Follow along!
