摘要:

由引文索引(Scopus,Google Scholar和Web of Science)检索的h指数用于衡量科学家的科学表现和研究影响力研究,基于科学家的出版物和引文数量。它也很容易获得,可用于科学家的业绩衡量和招聘决定。本研究的目的是调查这三个引文数据库,即Scopus,Google Scholar和Web of Science基于一组高被引研究人员(诺贝尔奖获得者科学家)的h指数的输出和结果之间的差异。本研究采立意抽样方法收集资料。结果表明,Scopus、Google scholar和Web of Science 3个数据库的h指数存在显著性差异,其中Google scholar h指数大于其他2个数据库的h指数。研究还表明,基于Google Scholar和Scopus的h指数之间存在显著的正相关关系。Scopus、Google Scholar和Web of Science的引文索引对科学家h指数的评价有一定的参考价值,但也存在一定的局限性。

英文摘要:

h-index retrieved by citation indexes (Scopus, Google scholar, and Web of Science) is used to measure the scientific performance and the research impact studies based on the number of publications and citations of a scientist. It also is easily available and may be used for performance measures of scientists, and for recruitment decisions. The aim of this study is to investigate the difference between the outputs and results from these three citation databases namely Scopus, Google Scholar, and Web of Science based upon the h-index of a group of highly cited researchers (Nobel Prize winner scientist). The purposive sampling method was adopted to collect the required data. The results showed that there is a significant difference in the h-index between three citation indexes of Scopus, Google scholar, and Web of Science; the Google scholar h-index was more than the h-index in two other databases. It was also concluded that there is a significant positive relationship between h-indices based on Google scholar and Scopus. The citation indexes of Scopus, Google scholar, and Web of Science may be useful for evaluating h-index of scientists but they have some limitations as well.
