摘　　要：中医辨证是中医临床立法、处方、用药的基础和前提。中医电子病历缺乏高质量语料,模型训练容易欠拟合,且四诊信息的症状表达形式存在较大差异,限制了网络模型对复杂症状的识别能力。针对上述问题,通过对四诊信息多通道的分开处理,以及人工构建的小规模知识图谱对模型训练进行知识的增强,提出了融合知识图谱的多通道中医辨证模型。实验结果表明,基于中医电子病历数据集,提出的模型在P@1指标、P@3指标、P@5指标上相比基线模型分别提高3.51%、3.38%、3.32%,相比其他网络结构模型也有不同程度的提高,验证了所提模型对中医辨证具有显著效果。Chinese Medicine syndrome differentiation is the basis and premise of Chinese Medicine clinical legislation,prescription and medication.Due to the lack of high-quality corpus of electronic medical records of Chinese Medicine,the model training is prone to underfitting,and the symptom expression forms of the four diagnostic information are quite different,which limits the recognition ability of the network model to complex symptoms.Aiming at the above problems,a multi-channel Chinese Medicine syndrome differentiation model integrating knowledge graphs was proposed by separately processing the multi-channels of the four diagnostic information and enhancing the knowledge of the model training by artificially constructed small-scale knowledge graphs.The experimental results show that based on the Chinese Medicine electronic medical record data set,the proposed model is 3.51%,3.38%,and 3.32%higher than the baseline model in terms of P@1,P@3,and P@5,respectively.Compared with other network structures,the model has also been improved to varying degrees,which verifies that the proposed model has a significant effect on Chinese Medicine syndrome differentiation.
