Chinese RoBERTa-Base Model for NER
Model description
The model is used for named entity recognition. It is fine-tuned by UER-py, which is introduced in this paper. Besides, the model could also be fine-tuned by TencentPretrain introduced in this paper, which inherits UER-py to support models with parameters above one billion, and extends it to a multimodal pre-training framework.
You can download the model either from the UER-py Modelzoo page, or via HuggingFace from the link roberta-base-finetuned-cluener2020-chinese.
How to use
You can use this model directly with a pipeline for token classification :
>>> from transformers import AutoModelForTokenClassification,AutoTokenizer,pipeline
>>> model = AutoModelForTokenClassification.from_pretrained('uer/roberta-base-finetuned-cluener2020-chinese')
>>> tokenizer = AutoTokenizer.from_pretrained('uer/roberta-base-finetuned-cluener2020-chinese')
>>> ner = pipeline('ner', model=model, tokenizer=tokenizer)
>>> ner("江苏警方通报特斯拉冲进店铺")

Training data
CLUENER2020 is used as training data. We only use the train set of the dataset.
Training procedure
The model is fine-tuned by UER-py on Tencent Cloud. We fine-tune five epochs with a sequence length of 512 on the basis of the pre-trained model chinese_roberta_L-12_H-768. At the end of each epoch, the model is saved when the best performance on development set is achieved.
python3 finetune/run_ner.py --pretrained_model_path models/cluecorpussmall_roberta_base_seq512_model.bin-250000 \

--output_model_path models/cluener2020_ner_model.bin \

Finally, we convert the pre-trained model into Huggingface's format:
python3 scripts/convert_bert_token_classification_from_uer_to_huggingface.py --input_model_path models/cluener2020_ner_model.bin \
--output_model_path pytorch_model.bin \
