一种文本相似度与BERT模型融合的手术操作术语归一化方法

A Method for Surgery Term Normalization Based on Text Similarity and BERT Model

该文探究手术操作术语归一化方法的构建。首先,分析手术操作术语归一化数据集的特点;其次,调研术语归一化的相关方法;最后,结合调研知悉的技术理论方法和数据集特征,建立手术操作术语归一化模型。该文融合文本相似度排序+BERT模型匹配开展建模,在2019年中文健康信息处理会议(CHIP2019)手术操作术语归一化学术评测中,验证集准确率为88.35%,测试集准确率为88.51%,在所有参赛队伍中排名第5。

To explore the method for surgery term normalization,this paper proposes a method of combining text similarity and BERT model.The model scheme is the text similarity ranking+BERT sentence pair matching model.This paper also analyzes the characteristics of the normalized surgery terms,and provides the related methods of clinical term normalization.In the CHIP2019 surgical term normalization task,the accuracy of this method on the verification set is 88.35%,and the accuracy on the test set is 88.51%,and the system based on this method ranked 5 th among all participating teams.
