Khmer Part of Speech Tagging with XLM RoBERTa
This model is a fine-tuned version of xlm-roberta-base on the khPOS dataset. It achieves the following results on the evaluation set:
- Loss: 0.1063
- Precision: 0.9512
- Recall: 0.9526
- F1: 0.9519
- Accuracy: 0.9735
Model description
The original paper achieved 98.15% accuracy while this model achieved only 97.35% which is close. However, this is a multilingual model so it has more tokens than the original paper.
Intended uses & limitations
This model can be used to extract useful information from Khmer text.
