Abstract:

[Purposes] This paper discusses the bibliometric characteristics, the evaluation, and applications of Journal Citation Indicator (JCI). [Methods] We first introduced the concept, calculation method, and bibliometric characteristics of JCI and then carried out the empirical research with data in InCites-JCR. [Findings] The citation time window, document type, and cited frequency adopted in the calculation of JCI are more reasonable than those for the calculation of impact factor. Moreover, the cited frequency is normalized to discipline, publication time, and document type so that it is more reasonable for the evaluation of the impact of academic journals, especially the evaluation of journals in different disciplines. [Conclusions] JCI is superior to impact factor in the impact evaluation of academic journals, which is more applicable to interdisciplinary evaluation and more objective for assessing the development of Chinese scientific journals.

摘要：

【目的】 探讨期刊引证指数(Journal Citation Indicator,JCI)的文献计量学特征及评价应用。【方法】 系统梳理JCI设计理念及相关理论,从InCites-JCR采集相关数据,对JCI进行实证研究。【结果】 与影响因子相比,JCI对引证时间窗口、文献类型、被引频次计数方法等设计更加合理,并且对被引频次按照学科、出版年和文献类型进行了标准化处理,能够更加合理地用于学术期刊影响力评价,尤其是期刊的跨学科评价。【结论】 JCI应用于学术期刊影响力评价具有明显的优越性,其设计体现了跨学科评价理念,能够较为客观地反映我国科技期刊的发展情况。
