Africa Pharmacovigilance Adverse Drug Reactions Dataset
A curated, structured dataset of 71 detailed adverse drug reaction (ADR) reports across 26 African countries, addressing a critical gap in pharmacovigilance data representation for African populations in global drug safety research.
🌍 Why This Dataset Matters
Most pharmacovigilance datasets are dominated by Western populations, leaving a significant gap in understanding drug safety profiles for African patients —… See the full description on the dataset page: https://huggingface.co/datasets/Oduwo/Africa_Pharmacovigilance_Adverse_Drug_Reactions.mlb-lineup-reactions

comparia-votes: one of the largest message-level preference datasets in French
Origin of this data: what is compar:IA?
Compar:IA is a conversational AI comparison tool (a "chatbot arena") developed within the French Ministry of Culture with a dual mission:
To raise awareness about model pluralism, cultural and linguistic biases, and the environmental challenges of conversational AI.
To improve conversational AI in French by publishing alignment datasets in… See the full description on the dataset page: https://huggingface.co/datasets/ministere-culture/comparia-reactions.Test_Reactions
