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).

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?

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

An overview of the work “Research Borderlands: Analysing Writing Across Research Cultures” by Shaily Bhatt, Tal August, and Maria Antoniak. The overview describes that We survey and interview interdisciplinary researchers (§3) to develop a framework of writing norms that vary across research cultures (§4) and operationalise them using computational metrics (§5). We then use this evaluation suite for two large-scale quantitative analyses: (a) surfacing variations in writing across 11 communities (§6); (b) evaluating the cultural competence of LLMs when adapting writing from one community to another (§7).

🖋️ 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❗

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.

A ven diagram showing that the recall and robustness, each of which has many different conceptions, interest when thinking about recall as "totality" and robustness as "worst-case performance". It's in this intersection that lexicographic recall (lexirecall) lives.

Yes! Thats exactly the case of TOT retrieval for academics :)

These approaches powered the TREC 2024 TOT track test queries and will continue into the 2025 track (trec-tot.github.io).

🔗Human query collection interface with visual stimuli set: github.com/kimdanny/hum...

⚡️Multi-Domain Coverage
Combining both methods allows TOT query evaluation in multiple domains. We tested simulated evaluation in Movie, Landmark, and Person domains. Moreover, we build a broader, more inclusive TOT test collection.

Human TOT query elicitation interface

Solution2️⃣: Human-Elicitation
We designed an interface with visual prompts to induce a TOT state in human participants. Their queries closely match authentic TOT queries and captures genuine TOT experiences in a controlled setting.

System rank correlation as a validation method for synthetic TOT queries.

Solution1️⃣: LLM-Elicitation
We built a TOT user simulator to produce synthetic queries. Results show high system rank correlation and linguistic similarity compared to real queries. This scalable simulated evaluation method overcomes data scarcity by simulating new queries on demand.

🤔Why the Problem?
TOT query data collection relies heavily on community question answering websites (e.g., Reddit). This causes data availability issues and domain bias (most TOT queries end up being about movies or books).

👅Tip-of-the-Tongue (TOT) search is a complex form of known-item search, shaped by the expression of partial recall, personal context, and uncertain memories. However, TOT research has long been hindered by the scarcity of high-quality TOT queries.

Tip of the Tongue Query Elicitation for Simulated Evaluation Tip-of-the-tongue (TOT) search occurs when a user struggles to recall a specific identifier, such as a document title. While common, existing search systems often fail to effectively support TOT scena...

🚨New Breakthrough in Tip-of-the-Tongue (TOT) Retrieval Research!

We address data limitations and offer a fresh evaluation method for these complex queries.

Figure showing that interpretations of gestures vary dramatically across regions and cultures. ‘Crossing your fingers,’ commonly used in the US to wish for good luck, can be deeply offensive to female audiences in parts of Vietnam. Similarly, the 'fig gesture,' a playful 'got your nose' game with children in the US, carries strong sexual connotations in Japan and can be highly offensive.

Did you know? Gestures used to express universal concepts—like wishing for luck—vary DRAMATICALLY across cultures?
