Hausa STEM Reasoning with Cultural Context
Abstract
We present the first large-scale bilingual Hausa-English STEM reasoning dataset with deep cultural adaptation, containing 2,640 high-quality question-answer pairs translated from the STEM-Reasoning-Complex dataset. Our work introduces the "Shehin Malamin Kimiyya" (The Wise Scholar of Science) translation framework, which transforms Western scientific concepts into culturally-embedded Hausa explanations using systematic… See the full description on the dataset page: https://huggingface.co/datasets/Tushe/hausa-stem-reasoning-with-cultural-context.stem-reasoning-ccbysa-010
