中文摘要:
      目的: 对国外医学领域知识库研究现状进行可视化分析,了解国外知识库研究热点,为学者今后开展医学领域知识库相关研究提供参考。方法:通过PubMed纳入国外知识库研究,采用书目共现分析系统(BICOMS-2)分析软件对发表时间、期刊、作者和主题词进行提取和整理,并生成作者和主要主题词共现矩阵,利用NetDraw绘制网络关系图,并利用gCLUTO 对主要主题词进行聚类分析。结果:国外医学领域第1篇知识库研究发表于1953年,直至2004年共计发表8篇,自2005年起文献年发表量开始上升,至2016年达到高峰。共有930种期刊刊载知识库相关文献,载文量超过50篇的共计16种期刊,其累计载文量达43.59%。共有25 961位学者参与知识库研究,发文量超过10篇的作者仅21位(0.08%),且作者间合作关系。纳入文献共包含4 050个主题词,通过对主要主题词聚类发现3个研究主题。结论:国外医学领域知识库研究关注度呈上升趋势,但研究学者间缺乏合作,研究主题较为局限,作者间需加强合作,进一步探索研究医学领域知识库的广度与深度。
英文摘要:
      Objective:To make visual analysis of the researches on foreign knowledge bases and obtain the research hot spots in the foreign medical field, so as to provide reference for researchers to carry out related research in the future. Methods: PubMed was searched to obtain the foreign researches on knowledge bases studies.The BICOMS-2 analysis software was used to extract the publication time, journals, authors, and medical subject headings (Mesh), and the co-occurrence matrix of the authors and Mesh was generated. NetDraw was used to draw a network diagram and gCLUTO was used to make cluster analysis. Results: The first foreign knowledge bases research in the field of medical health was published in 1953 and a total of 8 studies have been published before 2004. From 2005, the number of studies began to increase and reached the peak in 2016. A total of 930 journals published relevant researches of knowledge bases and 16 journals have published more than 50 studies, which published 43.59% studies. 25 961 researchers took part in the researches of the knowledge bases, and only 21 (0.08%) authors published more than 10 studies, and there was no cooperation between the authors. There were 4 050 Mesh in included studies, 3 research topics were drawn through cluster analysis based on the Mesh. Conclusion: More and more researchers focus on the knowledge bases in the foreign medical field. However, there is not enough cooperation among researchers, at the same time, there is the limitation of the research topics. The authors should strength the cooperation and explore the breadth and depth of the researches in the future.
