- Reposted by Danny To Eun Kim🎭 How do LLMs (mis)represent culture? 🧮 How often? 🧠 Misrepresentations = missing knowledge? spoiler: NO! At #CHI2026 we are bringing ✨TALES✨ a participatory evaluation of cultural (mis)reps & knowledge in multilingual LLM-stories for India 📜 arxiv.org/abs/2511.21322 1/10

- as AI increasingly supports shopping and ads, it’s worth remembering that retrieval often shapes who gets exposure in final generated output. in a recent paper, @teknology.bsky.social uses methods from fair ranking to assess and address exposure bias in downstream generation. 841.io/doc/fairrag....

- Reposted by Danny To Eun KimSome 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!
- Reposted by Danny To Eun KimGentle 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

- Reposted by Danny To Eun KimEver 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
- 👅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.
- 🤔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).

- Reposted by Danny To Eun KimMat 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?
