Tày-Vietnamese Parallel Dataset

The Tày–Vietnamese Parallel Dataset is a low-resource bilingual corpus designed for machine translation research. It consists of sentence-level aligned Tày and Vietnamese text pairs, manually curated and validated to ensure semantic accuracy. The dataset supports research on neural machine translation and cross-lingual learning for under-resourced languages.

Dataset Statistics

• —Number of sentence pairs: 20,600
• —Average sentence length (Tày): 7.50 tokens
• —Average sentence length (Vietnamese): 5.46 tokens

Limitations

• —Limited data size due to the low-resource nature of the Tày language
• —Coverage is limited to everyday communication and usage topics

Contributions

All authors contributed equally to the construction, preprocessing, and validation of the dataset.
