New Transformer Model Improves Tamil Spelling and Grammar Correction

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method for correcting spelling and grammar in Tamil, an agglutinative language with complex phonetic rules. Their approach uses progressively fine-tuned sequence-to-sequence transformers, specifically mT5-small and mBART-50 models, trained on a large synthetic corpus. This multi-stage training schedule targets different error types, from surface noise to contextual grammar and sandhi rules, significantly improving accuracy on a diagnostic set. The study also highlights a trade-off between sandhi recall and identity accuracy, and shows that a general Tamil-adapted instruction model performs poorly on this specialized task without task-specific supervision.

    Contextual Tamil Spelling and Grammar Correction Using Progressively Fine-Tuned Sequence-to-Sequence Transformers

    arXiv:2609.03273v1 Announce Type: new Abstract: Tamil spell and grammar correction is challenging because Tamil is an agglutinative low-resource language with rich verbal morphology, complex sandhi (phonetic transformation) rules at word boundaries, and a script of 247 distinct l…
