Then we demonstrate a generic search strategy that can be used to construct a representative dataset of bibliographic records of a domain of research. Next, progressively synthesized co-citation networks are constructed and visualized to aid visual analytic studies of the domain's structural and dynamic patterns and trends. Finally, trajectories of citations made by particular types of authors and articles are presented to illustrate the predictive potential of the analytic approach.Findings: The evolution of the science mapping research involves the development of a number of interrelated specialties. Four major specialties are discussed in detail in terms of four evolutionary stages: conceptualization, tool construction, application, and codification. Underlying connections between major specialties are also explored. The predictive analysis demonstrates citations trajectories of potentially transformative contributions.Research limitations: The systematic review is primarily guided by citation patterns in the dataset retrieved from the literature. The scope of the data is limited by the source of the retrieval, i.e. the Web of Science, and the composite query used. An iterative query refinement is possible if one would like to improve the data quality, although the current approach serves our purpose adequately. More in-depth analyses of each specialty would be more revealing by incorporating additional methods such as citation context analysis and studies of other aspects of scholarly publications.Practical implications: The underlying analytic process of science mapping serves many practical needs, notably bibliometric mapping, knowledge domain visualization, and visualization of scientific literature. In order to master such a complex process of science mapping, researchers often need to develop a diverse set of skills and knowledge that may span multiple disciplines. The approach demonstrated in this article provides a generic method for conducting a systematic review.Originality/value: Incorporating the evolutionary stages of a specialty into the visual analytic study of a research domain is innovative. It provides a systematic methodology for researchers to achieve a good understanding of how scientific fields evolve, to recognize potentially insightful patterns from visually encoded signs, and to synthesize various information so as to capture the state of the art of the domain.展开更多
目的分析国内外糖尿病运动在护理领域的研究现状,讨论当前研究热点和发展趋势。方法采用文献计量学研究方法,检索CNKI(China National Knowledge Infrastructure,中国知网)和Web of Science(简称WOS)核心合集数据库中自建库以来至2021年...目的分析国内外糖尿病运动在护理领域的研究现状,讨论当前研究热点和发展趋势。方法采用文献计量学研究方法,检索CNKI(China National Knowledge Infrastructure,中国知网)和Web of Science(简称WOS)核心合集数据库中自建库以来至2021年1月9日以“糖尿病”和“运动”为关键词的文献,导入Cite Space 5.7.R1可视化软件进行文献聚类和计量分析。结果国内外糖尿病运动研究文献发文量总体呈上升趋势;国内外高产作者总发文量分别为161篇和313篇,占比24.85%和3.67%,且尚未形成优质的核心作者群和研究团队;机构主力仍是医院临床科室、医学院和体育学院,尚未推动学科交叉进一步纵深发展,合作欠缺;分析发现关键词主要关注糖尿病类型、运动方式和结局指标,有氧和抗阻运动的个性化方案探索一直作为糖尿病不同群体的关注热点。结论未来研究可进一步开展针对糖尿病运动个性化方案的构建和相关知识的宣教,同时关注其发展机制,加强团队合作。展开更多
