我国能力验证项目研究热点可视化分析

为掌握我国能力验证工作的发展脉络和研究现状,采用文献计量和知识图谱的可视化分析法,选取1999—2017年国内公开发表的能力验证工作研究论文5145篇,使用Origin、统计产品与服务解决方案软件(SPSS)和中国知网(CNKI)计量可视化分析系统,从发文数量、作者、机构、基金等方面对该领域的研究论文进行分析,基于共词技术构建高频关键词共词矩阵,并对矩阵进一步聚类分析和多维尺度分析。分析结果认为能力验证研究热点集中在两大主题,分别为:能力验证项目实施过程,包括样品的均匀性稳定性检测和结果的评价;能力验证项目在实验室质量控制和管理中的作用。其中能力验证项目实施过程属于目前的重点和热点。所进行的研究对了解我国能力验证项目的发展动态,推动我国能力验证项目的深化和国际化将产生重要的意义。

Visualization map analysis of research hotspots in proficiency testing in China

In order to master the development process and research status of proficiency testing in China, the visualization analysis of bibliometrics and knowledge graph was adopted. The selected 5145 research papers about proficiency testing were published in 1999-2017. The software Origin, Statistical Products and Services Solutions (SPSS) and metrological visualization analysis system of China National Knowledge Infrastructure (CNKI) were used to analyze these papers in terms of quantity, author, organization and fund. The co-word matrix of high-frequency key words was constructed based in co-word technique followed by further clustering analysis and multidimensional scaling analysis. The analysis results suggested that the research hotspots in proficiency testing were focused on two topics: (1) the implementation process of proficiency testing, including the homogeneity and stability tests of sample as well as the evaluation of results; (2) the role of proficiency testing in quality control and management of laboratory. Among them, the implementation process of proficiency testing belonged to the research emphasis and hotspot at present. It had important significance to understand the development trend of proficiency testing in China and promote its deepening and internationalization in future.
