Clinicalnerpt Diagnostic

🚀 葡萄牙语临床命名实体识别 - 诊断

本诊断命名实体识别（NER）模型是 BioBERTpt 项目 的一部分，该项目训练了 13 个临床实体模型（与 UMLS 兼容）。所有来自 “pucpr” 用户的 NER 模型均基于巴西临床语料库 SemClinBr，从 BioBERTpt(all) 模型开始，经过 10 个训练周期，并采用 IOB2 格式进行训练。

示例文本

• 排尿期尿道膀胱造影，排尿后残余尿量显著。
• 检查时，仅在冲击部位出现轻度充血。

    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.",
