AfrimBert-QA

Model Description

AfrimBert-QA is a fine-tuned version of amidblue/mBertKE trained on the amidblue/AfriQuAD dataset. It is designed for extractive question answering — both monolingual and cross-lingual — across African languages.

Supported Languages

The model covers 15 languages (14 African + English for cross-lingual QA) across East, West, Central and Southern Africa. Counts below are estimated from stratified sampling of the full 14,400-row AfriQuAD dataset.

East Africa

West Africa

Southern / Central Africa

Cross-Lingual

Summary

Note: Luhya (luy), Kalenjin (kln), and Gusii (guz) appear in the dataset's HF metadata tags but were not observed in the sampled rows — they may be present in very small quantities or as part of cross-lingual pairs.

Training Data

The model was trained on a combination of the following datasets:

• KENSQUAD — Kenyan extractive QA dataset
• AFRIQA — Pan-African QA benchmark
• Custom data — Additional data collected for languages not covered by AFRIQA and KENSQUAD

Quick start

from transformers import pipeline

qa = pipeline("question-answering", model="amidblue/AfrimBert-QA")

# Luo (monolingual)
context  = "Ji mang'eny ok winjre gi kaka chama mar ODM iriembo. Tinde nitie koko mang'eny e chama no."
question = "Chama mane ema ji oko hero kaka iriembo?"

result = qa(question=question, context=context)
print(f"Question : {question}")
print(f"Answer   : {result['answer']}")
print(f"Score    : {result['score']:.4f}  |  span [{result['start']}:{result['end']}]")
