摘要：

【目的】为了有效地检测期刊过度自引,更好地遏制操纵影响因子的行为。【方法】以食品科技SCI来源期刊为例,运用SPSS作箱形图筛选出过度自引的期刊,采用理论分析与比较分析法,探讨了2年自被引率作为期刊过度自引检测指标所具有的优势。【结果】与自被引率相比,2年自被引率的离散程度更大,更利于识别过度自引,对过度自引更加敏感、反应速度更快,更利于在第一时间内检测到过度自引的期刊。【结论】2年自被引率可以作为一种更好的定量指标用于检测期刊过度自引。

Abstract:

[Purposes]This paper aims to effectively detect excessive self-citation of academ ic journals and restrain the behavior of manipulating the impact factor.[Methods]The author screened out journals having excessive self-citation from SCIsource journals of food science and technology according to SPSS box plot,and discussed the advantages of the two-year self-cited rate as the excessive self-citation detection index through the theoretical analysis and comparison analysismethod.[Findings]Compared to the self-cited rate, the two-year self-cited rate has larger dispersion degree, is preferable to identify excessive self-citation, is more sensitive to excessive self-citation, and has higher response speed, so that it ismore beneficial to successful detection of journals w ith excessive self-citation.[Conclusions]The two-year self-cited rate is a preferable quantitative index for detecting excessive self-citation of academ ic journals.
