AfriSUD: A Dependency Treebank Collection for Evaluating Models on African Languages

arXiv:2606.12708v1 Announce Type: new Abstract: Despite their linguistic diversity and global significance, African languages remain underrepresented in research and resources to support NLP. We aim to bridge this gap by introducing AfriSUD, the first large-scale collection of syntactically annotated treebanks for nine diverse African languages spanning major language families and regions across Sub-Saharan Africa. Using the Surface-Syntactic Universal Dependencies (SUD) framework, our community-led effort provides high-quality, native-speaker verified data that capture typological key feature

Why this matters
Why now

The increasing focus on AI development and the recognized dependency on data from a limited set of languages are driving efforts to diversify linguistic resources for NLP.

Why it’s important

This initiative addresses a critical gap in AI's global applicability by enabling better NLP models for a large and diverse linguistic population, impacting future AI development and market access.

What changes

The availability of high-quality, large-scale linguistic data for African languages will improve the performance and fairness of AI models in these regions, fostering local AI innovation and reducing reliance on foreign-developed models unsuited for local contexts.

Winners
  • · African AI developers
  • · African language communities
  • · Global NLP researchers
  • · Companies seeking to expand AI services in Africa
Losers
  • · AI models without diverse training data
  • · Companies unable to adapt to linguistic diversity
Second-order effects
Direct

AfriSUD provides foundational data for developing more effective and inclusive natural language processing models for African languages.

Second

Improved NLP capabilities will accelerate the development of AI applications tailored to African markets and cultural contexts, potentially fostering local tech ecosystems.

Third

This could contribute to the development of 'sovereign AI' capabilities within African nations, reducing dependency on models trained predominantly on Western or Asian linguistic data.
