【目的】 介绍国外新型智能引用分析系统Scite(Smart Citation),探讨近年出现的引用分析变化,为我国科技期刊评价提出依据和建议。【方法】 通过介绍Scite的工作原理和主要功能,使用案例分析不同学科、不同期刊的Scite指数(Scite Journal Index,SJI)。【结果】 不同学科期刊引文质量差异很大,自然科学期刊SJI比社会科学高;在自然学科中,医学期刊SJI比数学、物理和化学低;与世界顶级期刊相比,中国期刊表现欠佳。SJI与被引频次呈负相关。【结论】 Scite基于引文语境分析引用的新模式更科学合理,对我国科技期刊评价有一定的启示和帮助。
[Purposes] This paper introduces the new foreign smart citation analysis system Scite and discusses the new changes in citation analysis in recent years, which is expected to lay a basis and provide suggestions for the evaluation of scientific journals in China. [Methods] The working principle and main functions of Scite were introduced and the Scite indexes (SJIs) of different disciplines and different journals were analyzed based on case analysis. [Findings] The quality of citations is different among journals of different disciplines. The SJIs of journals on natural sciences are higher than those on social sciences. For natural sciences, medical journals see a lower SJI than journals on mathematics, physics, and chemistry. The total cites of Chinese journals are lower than those of world top journals. SJI is negatively related to cited frequency. [Conclusions] Scite, which analyzes citations based on the context, is more scientific and reasonable, and has certain enlightenment to the evaluation of scientific journals in China.
