    • 摘要: 随着医疗大数据时代的到来,知识互联受到了广泛的关注.如何从海量的数据中提取有用的医学知识,是医疗大数据分析的关键.知识图谱技术提供了一种从海量文本和图像中抽取结构化知识的手段,知识图谱与大数据技术、深度学习技术相结合,正在成为推动人工智能发展的核心驱动力.知识图谱技术在医疗领域拥有广阔的应用前景,该技术在医疗领域的应用研究将会在解决优质医疗资源供给不足和医疗服务需求持续增加的矛盾中产生重要的作用.目前,针对医学知识图谱的研究还处于探索阶段,现有知识图谱技术在医疗领域普遍存在效率低、限制多、拓展性差等问题.首先针对医疗领域大数据专业性强、结构复杂等特点,对医学知识图谱架构和构建技术进行了全面剖析;其次,分别针对医学知识图谱中知识表示、知识抽取、知识融合和知识推理这4个模块的关键技术和研究进展进行综述,并对这些技术进行实验分析与比较.此外,介绍了医学知识图谱在临床决策支持、医疗智能语义检索、医疗问答等医疗服务中的应用现状.最后对当前研究存在的问题与挑战进行了讨论和分析,并对其发展前景进行了展望.

       

      Abstract: With the advent of the medical big data era, knowledge interconnection has received extensive attention. How to extract useful medical knowledge from massive data is the key for medical big data analysis. Knowledge graph technology provides a means to extract structured knowledge from massive texts and images.The combination of knowledge graph, big data technology and deep learning technology is becoming the core driving force for the development of artificial intelligence. The knowledge graph technology has a broad application prospect in the medical domain. The application of knowledge graph technology in the medical domain will play an important role in solving the contradiction between the supply of high-quality medical resources and the continuous increase of demand for medical services.At present, the research on medical knowledge graph is still in the exploratory stage. The existing knowledge graph technology generally has several problems such as low efficiency, multiple restrictions and poor expansion in the medical domain. This paper firstly analyzes the medical knowledge graph architecture and construction technology for the strong professionalism and complex structure of big data in the medical domain. Secondly, the key technologies and research progress of the three modules of knowledge extraction, knowledge expression, knowledge fusion and knowledge reasoning in medical knowledge map are summarized. In addition, the application status of medical knowledge maps in clinical decision support, medical intelligence semantic retrieval, medical question answering system and other medical services are introduced. Finally, the existing problems and challenges of current research are discussed and analyzed, and its development is prospected.
