🚨 New paper alert!

🇯🇵🤔 Why are all LLMs Obsessed with Japanese Culture? On the Hidden Cultural and Regional Biases of LLMs 🇯🇵🤔

👉 We find that LLMs show strong regional preferences, often disproportionately favoring certain countries, such as Japan. 🇯🇵

If your research is around metaphor detection and interpretation, this article is for you! It introduces Meta4XNLI, the first parallel dataset for Natural Language Inference (NLI), in both English
and Spanish: https://t.co/GAmhTKtbQU #NLProc

Our weekly seminars are back! 🎉
We welcomed @eli_sanba and @joseba_fdl from the University of the Basque Country.
Elisa Sanchez-Bayona discussed Automatic Metaphor Processing, and Joseba Fernandez de Landa Aguirre spoke on instructing LLMs for low-resource languages.

📅 Tue, 29/07 10:30-12:00 Hall 5 (54)
Joint work w/ @ragerri @Hitz_zentroa
See you there!

I am happy to announce that our latest work on Visually Augmented Language Models has been accepted in #COLING2025

We present Blind-VaLM, a simple approach removing the need for explicit images to visually augment an LM, while still achieving strong performance on VLU and NLU.

[Irune Zubiaga @iruzubiaga]

🚨Happy to share that our paper “A LLM-Based Ranking Method for the Evaluation of Automatic Counter-Narrative Generation" has been accepted at #EMNLP2024 Findings! 🎉

Congrats to all coauthors! @Aitor57 @ragerri

today, im excited to release a repository that implements llama3 from scratch -- every matrix multiplication from attention across multiple heads, positional encoding and every other layer in between has been carefully unwrapped & explained. have fun :)

Can you imagine having all the evidence of data contamination gathered in one place?

📢As part of the CONDA workshop, we present the Data Contamination Evidence Collection, a shared task on reporting contamination.

Do LMs struggle to understand the meaning of metaphorical expressions? We tested if LMs correctly perform NLI between a premise and a hypothesis when the inference depends on a metaphor. Results suggest that LMs perform worse when metaphors affect the inference in the NLI task.

[Elisa Sanchez-Bayona @eli_sanba]

Do LMs correctly interpret metaphor? We present Meta4XNLI! The first EN-ES pallalel dataset annotated for metaphor detection and interpretation via NLI; joint work w/ @ragerri @IxaGroup @Hitz_zentroa

Are LMs able to mark which words in a sentence are not literal?  We developed a series of multilingual, cross-lingual and cross-domain experiments to evaluate their capabilities in the task of metaphor identification.

[Leshem (Legend) Choshen 🤖🤗 @LChoshen]

Methapor dataset with some twists
They annotated Spanish 117K tokens (3.6K sentences) for being metaphoric or not

🟦new dataset
🟦2-10% of sentences have a metaphor🤨
🟦Cross lingual - SoTA on Spanish, and they didn't even multitask
