Usage
本项目开源在实体识别项目:nerpy,可支持bertspan模型,通过如下命令调用:
>>> from nerpy import NERModel
>>> model = NERModel("bertspan", "shibing624/bertspan4ner-base-chinese")
>>> predictions, raw_outputs, entities = model.predict(["常建良,男,1963年出生,工科学士,高级工程师"], split_on_space=False)
entities: [('常建良', 'PER'), ('1963年', 'TIME')]

This model does not have enough activity to be deployed to Inference API (serverless) yet. Increase its social
visibility and check back later, or deploy to Inference Endpoints (dedicated)
instead.
