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.
