摘要
将共引分析法、共词分析法与战略坐标相结合揭示学科主题演变.通过引文共引聚类描述普通外科学领域研究的历史,借助战略坐标的思想,绘制"引文战略坐标图",从而进一步了解各研究热点的新颖度和关注度;通过主题词共现聚类发现普通外科学领域当前的研究热点,并在此基础上进行战略坐标分析,揭示各热点研究的发展阶段,以期为该学科专业人员和科研管理人员决策提供参考.
Abstract
Co-citation analysis, co-word analysis and strategic coordinates are combined to make known the subject theme evolu-tion. The research history of general surgery is described by eo-citation eluster analysis, citation strategic diagram is pictured by the theory of strategy coordinates to learn more about the novelty and attention of each hot topic. The present research focused on general surgery that would be found by co-words cluster analysis, and stages of development about each topic are discussed by strategic coordinates based of cluster results. It is helpful to provide a decision-making reference for professionals and managers.
