The Sahelian NLP challenge
Why generic LLMs fail here.
Tone & diacritics
In Hausa and Zarma, a wrongly marked tone changes the meaning. Scrapers flatten these subtleties.
Agglutinative morphology
BPE and WordPiece split morphemes into meaningless 1–2 character fragments.
Real-world code-switching
Local syntax, Arabic vocabulary, French terminology. Only a speaker who is also an engineer can label without noise.
