NormAd: A Framework for Measuring the Cultural Adaptability of Large Language Models (2025.naacl-long)
Copied to clipboard
| Challenge: | Large language models (LLMs) are widely used and engage millions of users from diverse contexts and cultures. |
| Approach: | They propose an evaluation framework to assess LLMs’ cultural adaptability by measuring their ability to judge social acceptability across varying levels of cultural norm specificity. |
| Outcome: | The proposed model shows stronger adaptability to English-centric cultures over those from the Global South. |
AdaPT: A Set of Guidelines for Hyperbolic Multimodal Multilingual NLP (2024.findings-naacl)
Copied to clipboard
| Challenge: | Euclidean space is used for training neural models and performing arithmetic operations, but many data types have complex geometries and cannot be captured in the Euclidesan space. |
| Approach: | They propose a set of guidelines for initialization, parametrization, and training of neural networks that can be generalized over existing neural network training methodologies. |
| Outcome: | The proposed framework outperforms Euclidean methods on three tasks over 12 languages and modalities on a variety of domains. |

| Challenge: | Existing methods for multilingual entity linking are limited by textual contexts and limited resources. |
| Approach: | They propose a testbed system for multilingual multimodal entity linking using BBC news articles paired with corresponding images in five languages. |
| Outcome: | The proposed system improves accuracy for entities with ambiguous textual contexts and models with weak multilingual abilities. |
