This repository contains the code associated with the paper Thai Nested Named Entity Recognition Corpus presented at ACL2022(findings).

This work presents the first Thai Nested Named Entity Recognition (N-NER) dataset. Thai N-NER consists of 264,798 mentions, 104 classes, and a maximum depth of 8 layers obtained from news articles and restaurant reviews, a total of 4894 documents. Our work, to the best of our knowledge, presents the largest non-English N-NER dataset and the first non-English one with fine-grained classes.

To get started, install the library:

pip install thai_nner

First, download the necessary resources (models, datasets, and pre-trained language models) from here and use the convert_model2use.py script to prepare it.

python convert_model2use.py -i 0906_214036/checkpoint.pth -o model.pth

import os
os.environ['CUDA_VISIBLE_DEVICES'] = "0"
from thai_nner import NNER

nner = NNER("model.pth")
tags = nner.get_tag("วันนี้วันที่ 5 เมษายน 2565 เป็นวันที่อากาศดีมาก")
print(tags)

• Python Library Demo
• Functionality Testing

python train.py --device 0,1 -c config.json

python test_nne.py --resume [PATH]/checkpoint.pth
