MasakhaNER: Named Entity Recognition for African Languages (2021.tacl-1)

Copied to clipboard

Challenge: (2020) African languages are underrepresented in existing natural language processing datasets, research, and tools due to lack of datasets and reproducible results.
Approach: They propose to create a dataset for named entity recognition (NER) in ten African languages.
Outcome: The results of the first large dataset for named entity recognition (NER) in ten African languages are released to inform future research on African NLP.
IrokoBench: A New Benchmark for African Languages in the Age of Large Language Models (2025.naacl-long)

Copied to clipboard

Challenge: Large language models (LLMs) are limited to a few high-resource languages . many low-resourced languages are evaluated only on basic text classification tasks .
Approach: They propose to use IrokoBench to evaluate 17 low-resource African languages . they use human-translated benchmark datasets to evaluate zero-shot, few-shot and translate-test settings .
Outcome: The proposed model performs well in English and French, but the highest performing model perform poorly in proprietary models.
INJONGO: A Multicultural Intent Detection and Slot-filling Dataset for 16 African Languages (2025.acl-long)

Copied to clipboard

Challenge: Slot-filling and intent detection tasks are well-established tasks in Conversational AI, but current benchmarks for these tasks rely on evaluations of low-resource languages and translations from English benchmarks.
Approach: They propose to use a multilingual, open-source benchmark dataset for 16 African languages with utterances generated by native speakers across diverse domains.
Outcome: The proposed dataset compares multilingual transformer models and prompting large language models (LLMs) with the English language.
