面向继续医学教育的多模态围产保健知识图谱构建研究

Construction of Multimodal Perinatal Health Care Knowledge Graph towards Continuing Medical Education

目的/意义将多模态知识图谱应用于围产保健继续医学教育,以提高医护人员围产保健服务质量。方法/过程结合北京协和医院围产保健继续教育项目学员需求和课程主要特点构建顶层本体,对本体类、关系和属性进行设计和定义,利用不同粒度教学资源表示教学内容,利用Protégé软件构建围产保健知识图谱概念层和实例层。基于团队自主研发的医学知识服务平台MedKaaS,实现多模态实体进一步交互式构建,以及围产保健课程知识的可视化、检索和问答。结果/结论该多模态知识图谱实现了围产保健课程内容的语义化整合,有助于学员直观和有针对性地学习围产保健知识。

Purpose/Significance Using multimodal knowledge graph in perinatal health care continuing medical education is conducive to improving the quality of perinatal health care service for medical staff.Method/Process The top-level ontology is constructed based on the needs of students of perinatal health care continuing education project in Peking Union Medical College Hospital and the main characteristics of the courses,the classes,relationships and attributes are designed and defined,and different granularity teaching resources are used to represent the teaching content.The Protégésoftware is used to construct the instances of perinatal health care knowledge graph.Based on MedKaaS developed by our team,the further interactive construction of multi-modal entities,visualization,retrieval and question and answer of perinatal health care course knowledge are realized.Result/Conclusion The multimodal knowledge graph realizes the semantic integration of perinatal health care course content,and helps students learn perinatal health care knowledge intuitively and optionally.
