摘要
应用共词分析和可视化综合分析方法,分析了我国神经病学领域的研究热点及发展变化。结果表明,高频词之间的共现网络关系可以反映学科领域的主题结构和热点,类团演变和类团地位分析,可以动态地反映研究热点和发展动向,综合分析词和类团则可以直观而全面地展现研究热点及发展。
The research hot spots and development in domestic neurology were analyzed by co-words analysis, visual analysis and the combination of them, which showed that the co-occurrence relation between high frequency words could display the structure and hot spots of subject headings in neurology, analysis of the cluster evolution and position could dynamically reveal the hot spots and development in neurology, and comprehensive analysis of words and their classes could directly and overall demonstrate the hot spots and development in neurology.
