BRIGHTER: BRIdging the Gap in Human-Annotated Textual Emotion Recognition Datasets for 28 Languages (2025.acl-long)

Copied to clipboard

Challenge: Emotion recognition is an umbrella term for several NLP tasks, but most work on high-resource languages has focused on low-resourced languages.
Approach: They propose to use emotion recognition to describe perceived emotions in 28 different languages and across several domains to identify and annotate the datasets.
Outcome: The proposed datasets cover low-resource languages from Africa, Asia, Eastern Europe, and Latin America, with instances labeled by fluent speakers.
AfriHate: A Multilingual Collection of Hate Speech and Abusive Language Datasets for African Languages (2025.naacl-long)

Copied to clipboard

Challenge: Hate speech and abusive language are global phenomena that need sociocultural background knowledge to be understood, identified, and moderated.
Approach: They propose to use a multilingual dataset to collect hate speech and abusive language in 15 African languages to help improve model performance.
Outcome: The proposed datasets are based on tweets annotated by native speakers familiar with the regional culture and show that they perform well in low-resource settings.
AfriMTE and AfriCOMET: Enhancing COMET to Embrace Under-resourced African Languages (2024.naacl-long)

Copied to clipboard

Challenge: Recent advances in machine translation (MT) have focused on scaling multilingual machine translation models and evaluation data to hundreds of languages, including multiple under-resourced languages.
Approach: They propose to use n-gram matching metrics to measure progress in multilingual machine translation to 13 typologically diverse African languages to create high-quality human evaluation data with simplified MQM guidelines.
Outcome: The proposed metrics have a higher correlation with human judgments than n-gram matching metrics such as BLEU and METEOR.
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.
