New corpus tackles NLP challenges for Vietnam's minority languages

By PulseAugur Editorial · [2 sources] ·

Researchers have developed CKTN, a new corpus and benchmark designed to address the scarcity of natural language processing resources for minority languages in Vietnam, specifically Cham, Khmer, and Tay-Nung. The corpus, containing 44,367 documents and 24 million subword tokens, highlights how existing multilingual encoders struggle with these languages due to differences in script and standardization. A novel script-aware adaptation method, involving vocabulary augmentation and calibrated replaced-token pretraining, was developed to improve model performance and reduce fragmentation, leading to stronger classification results.
