国际健康信息研究主题的演化路径分析

基于WoS核心集检索健康信息领域研究性文献4 023篇，以关键词为分析单元，共词分析和聚类分析为方法，SciMAT为工具，识别不同时期的研究主题及其演化路径。研究发现国际健康信息的研究始于1923年，早期发展迟缓、主题少、热度低；后期呈多样化发展。各时期研究主题变化大，演化关系复杂，在两个研究方向上呈现4条演化路径：健康信息查询和健康素养是主要知识脉络，将持续成为研究热点；公共健康和健康信息技术早期受关注程度低，演化过程不稳定，2008年后受关注程度升高，研究地位上升，成为研究热点和有发展潜力的基础研究方向。

Analysis of Themes Evolutions of International Research Papers on Health Information

Based on WoS,the paper collected a total of 4023 research papers related to health information.By selecting keywords as the units of analysis,co-word analysis and cluster analysis as methods,SciMAT as the knowledge mapping tool,this paper identified research topics and their evolution paths in different periods.Research demonstrated that the study of international health information began in 1923,with slow development,a few research topics and less attention in the early stage.Then the research turned to diversification.Research topics changed greatly in the different periods and evolutionary relationships were complex.Research also revealed four evolution paths on two different research directions.Evolution paths of health information seeking and health literacy were important and would continue to be hot topics.Evolution paths of public health and health information technology received less attention with unstable evolutionary processes in the early stage.After 2008,topics of the two paths received widespread attention and high research status,which became research hotspots and the basic research direction with development potential.
