目的/意义 提出基于国家标准的电子病历数据元抽取方法,以实现电子病历数据的细粒度共享.方法/过程 利用ALBERT、BiLSTM和CRF模型对电子病历进行序列标注,并根据标注结果生成一组候选数据元;针对每个候选数据元,采集其上下文信息并形成一个增强的键向量;计算该向量与标准向量之间的相似度,据此判断候选数据元是否有效.结果/结论 该方法F1值为90.32%,效果较好.
A Method for Extracting Data Elements from Chinese Electronic Medical Records
Purpose/Significance A method is proposed for extracting data elements from electronic medical records(EMR)based on national standards,helping to achieve fine-grained sharing of EMR data.Method/Process The ALBERT,BILSTM and CRF models are used to perform sequence labeling on EMR,and a set of candidate data elements based on labeling results are generated.For any can-didate data elements,the contextual information is collected to form an enhanced key vector.Then the similarity between the vector and the standard vector is calculated to determine whether the candidate data element is valid.Result/Conclusion The F1 value is 90.32%,indicating the proposed method has a good performance.
