摘　　要：得益于信息化技术的快速发展和医疗信息系统的普及,医学数据库中积淀了海量的医学事实,如患者临床诊疗事件以及医学专家共识等.如何从医学事实中提炼出知识,进而对其管理和合理利用,是推进诊疗自动化和智能化的关键.知识图谱作为一种新型的知识表示工具,能够有效地挖掘和组织大规模医学事实中的信息,受到医疗领域从业人员的广泛关注.然而,现有医疗知识图谱普遍存在规模小、限制多、可扩展性差等问题,面向医学事实的知识表达能力有限.为此,提出一种双层医疗知识图谱架构,通过对英文患者诊疗事件和中文专家共识进行信息抽取,构建得到一个跨语言、多模态、动态更新、可拓展性强的10亿级医疗知识图谱,可提供更加精准的智能医疗服务.Benefiting from the rapid development of information technology and the widespread adoption of medical information systems,a vast amount of medical knowledge has been accumulated in medical databases,including patient clinical treatment events and medical expert consensus.It is crucial to extract knowledge from these medical facts and effectively manage and utilize them,which can advance the automation and intelligence of diagnosis and treatment.Knowledge graphs,as a novel knowledge representation tool,can effectively mine and organize information from abundant medical facts and have received extensive attention in the medical field.However,existing medical knowledge graphs often suffer from limitations such as small scale,numerous restrictions,poor scalability,and so on,leading to a limited ability to express knowledge from medical facts.To address these issues,this proposes a bilayer medical knowledge graph architecture and employs information extraction techniques on both English patient clinical treatment events and Chinese medical expert consensus to construct a billion-scale medical knowledge graph that is cross-lingual,multimodal,dynamically updated,and highly scalable,aiming to provide more accurate,intelligent medical services.

关 键 词：医学事实 医疗知识图谱 双层知识表示 信息抽取 知识融合
