AfriQA is the first cross-lingual question answering (QA) dataset with a focus on African languages. The dataset includes over 12,000 XOR QA examples across 10 African languages, making it an invaluable resource for developing more equitable QA technology.

The train/validation/test sets are available for all the 10 languages.

Supported Tasks and Leaderboards

  • question-answering: The performance in this task is measured with F1 (higher is better) and Exact Match Accuracy.
