BioBERTpt - 葡萄牙语临床和生物医学BERT

BioBERTpt - A Portuguese Neural Language Model for Clinical Named Entity Recognition 这篇论文包含了基于葡萄牙语的临床和生物医学BERT模型，初始化使用了BERT-Multilingual-Cased，并且在临床笔记和生物医学文献上进行了训练。

这个模型卡片描述了BioBERTpt（all）模型，它是将临床叙述和葡萄牙语生物医学文献结合起来的完整版本。

如何使用模型

通过transformers库加载模型：

from transformers import AutoTokenizer, AutoModel
tokenizer = AutoTokenizer.from_pretrained("pucpr/biobertpt-all")
model = AutoModel.from_pretrained("pucpr/biobertpt-all")

    abstract = "With the growing number of electronic health record data, clinical NLP tasks have become increasingly relevant to unlock valuable information from unstructured clinical text. Although the performance of downstream NLP tasks, such as named-entity recognition (NER), in English corpus has recently improved by contextualised language models, less research is available for clinical texts in low resource languages. Our goal is to assess a deep contextual embedding model for Portuguese, so called BioBERTpt, to support clinical and biomedical NER. We transfer learned information encoded in a multilingual-BERT model to a corpora of clinical narratives and biomedical-scientific papers in Brazilian Portuguese. To evaluate the performance of BioBERTpt, we ran NER experiments on two annotated corpora containing clinical narratives and compared the results with existing BERT models. Our in-domain model outperformed the baseline model in F1-score by 2.72{\%}, achieving higher performance in 11 out of 13 assessed entities. We demonstrate that enriching contextual embedding models with domain literature can play an important role in improving performance for specific NLP tasks. The transfer learning process enhanced the Portuguese biomedical NER model by reducing the necessity of labeled data and the demand for retraining a whole new model.",
