【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。
【Objective】 In order to effectively detect excessive self-introduction periodicals, to better control the manipulation of the impact of factor behavior. 【Method】 Taking SCI source journals of food science and technology as an example, SPSS was used to select over-self-cited periodicals, and theoretical and comparative analysis methods were used to explore the two-year self-cited rate as the index of excessive self-citation in periodicals The advantages. 【Result】 Compared with self-cited rate, the two-year self-quoted rate is more discrete, more conducive to the identification of excessive self-citation, more sensitive to excessive self-citation and faster response, which is more conducive to detecting excessive in the first time Self-cited periodicals. 【Conclusion】 Two-year self-cited rate can be used as a better quantitative index to detect excessive self-introduction of periodicals.
