摘要
学术界虽然重视期刊论文到达被引峰值的时间,但一直不以该时间计算影响因子。文章分析了这种现象产生的原因,并对影响因子与5年影响因子评价时存在对越早的论文越重视,时效性差,隐含权重不合理等问题进行了分析。在此基础上提出2年时间影响因子与5年时间影响因子的概念,采用中国知网(CNKI)引文数据库,基于CSSCI图书馆情报与文献学期刊的研究结果表明:时间影响因子与影响因子尽管排序有一定的差异,但其统计学特征、数据分布、相关度等与影响因子相似度较高。时间影响因子时效性高,计算权重更合理,可以用来代替影响因子与5年影响因子进行学术期刊评价。
Although academia attaches importance to the time when journal articles reach the citation peak,the time is not used to calculate the impact factor.This paper explores the causes of this phenomenon,and analyzes the problems such as the more attention to the earlier paper,poor timeliness and unreasonable hidden weight when evaluating the impact factor and the five-year impact factor.Therefore,the paper proposes the concept of two-year time impact factor and five-year time impact factor.Taking the CSSCI journal of library information and philology as an research object and based on the citation data of CNKI,the research shows that although there is a some sequence difference between the time impact factor and the impact factor,their statistical characteristics,data distribution,correlation and other factors have higher similarity with the impact factor.The time impact factor has high timeliness and the calculation weight is more reasonable,which can be used to replace the impact factor and the five-year impact factor for academic journal evaluation.
