Automatic Correction of Writing Anomalies in Hausa Texts
Wali, Ahmad Mustapha, Nisioi, Sergiu
Hausa texts are often characterized by writing anomalies such as incorrect character substitutions and spacing errors, which sometimes hinder natural language processing (NLP) applications. This paper presents an approach to automatically correct the anomalies by finetuning transformer-based models. Using a corpus gathered from several public sources, we created a large-scale parallel dataset of over 450,000 noisy-clean Hausa sentence pairs by introducing synthetically generated noise, fine-tuned to mimic realistic writing errors. Moreover, we adapted several multilingual and African language-focused models, including M2M100, AfriTEVA, mBART, and Opus-MT variants for this correction task using SentencePiece tokenization. Our experimental results demonstrate significant increases in F1, BLEU and METEOR scores, as well as reductions in Character Error Rate (CER) and Word Error Rate (WER). This research provides a robust methodology, a publicly available dataset, and effective models to improve Hausa text quality, thereby advancing NLP capabilities for the language and offering transferable insights for other low-resource languages.

Bill Gates warns that China, other powers will fill void if U.S. cuts foreign aid
One of Bill Gates' Arizona-based investment firms, Belmont Partners, just purchased close to 25 thousand acres of land in Tonoph, Arizona for $80 million dollars to develop a "smart city!" Veuer's Chandra Lanier has the story. Bill Gates visiting an agricultural facility in Adama, Ethiopia, that processes, cleans, bags and ships white pea beans, red kidney beans, and chickpeas grown in Ethiopia to European markets. Tech pioneer Bill Gates thinks the U.S. can keep its historically influential role as a global leader. But for a second year in a row, he cautioned that the nation risks losing its geopolitical clout if the Trump administration succeeds in slashing foreign aid, as proposed Monday in a new federal budget that prioritizes a jump in military spending. Last year, the White House tried to reduce foreign aid by one-third, but Congress did not approve the cuts.
