基于WoS和Scopus数据库的期刊评价指标研究

Research on Periodical Evaluation Index Based on WoS and Scopus Database

本文选取被WoS数据库和Scopus数据库同时收录的21种中国材料类期刊作为研究对象,分别统计各期刊2015年的被引频次、载文量、IF、IF5、ES、SJR、H指数和SNIP,研究WoS数据库和Scopus数据库的引文评价核心指标对期刊评价的相关性和差异性,为构建科技期刊综合评价指标体系提供参考。结果表明:SJR、H指数、SNIP、被引频次、IF、IF5和ES七个指标两两之间都具有显著的相关性,其中SJR、IF和IF5之间的相关性最高。SJR排名、H指数排名、SNIP排名、IF排名、IF5排名、ES排名之间差异不显著。Scopus数据库和WoS数据库评价期刊时具有可比性和可替代性。

In this paper, 21 kinds of Chinese materials journals included in the WoS database and Scopus database were selected as the research objects, the cited frequency, loading volume, IF, IF5, ES, SJR, H index and SNIP were respectively counted, the relevance and difference of the periodical evaluation was studied by citation evaluation core indexes of WoS database and Scopus database to provide reference for the construction of comprehensive evaluation index system of sci-tech periodicals. The results showed that there were significant correlations among SJR, H index, SNIP, cited frequency, IF, IF5 and ES, and the correlation among SJR, IF and IF5 was the highest, and the difference among SJR ranking, H index ranking, SNIP ranking, IF ranking, IF5 ranking, ES ranking was not significant.Scopus database and WoS database are comparable and replaceable when evaluating journals.
