知识图谱与h指数分析方法比较研究——以我国军事医学高被引论文分析为例

Mapping knowledge domains and h-index in analyzing high-cited articles on Chinese military medicine:a comparative analysis

目的比较知识图谱与h指数两种分析方法间的差异,寻找分析我国军事医学高被引论文的最佳策略。方法基于Java平台的知识图谱分析软件CiteSpaceⅡ和h指数分析方法。结果本文通过对《中国图书馆分类法》有关条目的分析,制定相应的检索策略,编辑在CNKI数据库中检索军事医学类论文的检索式,得出了2000～2009年我国军事医学类的高被引论文。分别用两种方法分析了高被引论文的关键词和关键作者,并由此得出我国军事医学研究的高水平领域和著名作者,以及新的研究热点。结论知识图谱分析更具优势但仍需与h指数结合使用。

Objective To compare the mapping knowledge domains and the h-index and to find the best method for analyzing high-cited articles on Chinese military medicine. Methods CiteSpace Ⅱ was running on Java platform. Results The searching language for articles about military medicine in CNKI was edited. High-cited articles from 2000 to 2009 were identified. High-cited key-words and high-cited authors by the two methods were analyzed to find some high-level domains, some famous authors and some new domains of military medicine in China. Conclusion Mapping knowledge domains are superior to h-index. The two methods should be used together.
