[目的/意义]基于论文被引频次8个区段百分位数排序(percentile rank 8,PR8)赋分,尝试构建新的跨学科期刊评价指标:期刊PR8指数(journal index for PR8,JIPR8),并检验JIPR8的跨学科期刊评价效果。[方法/过程]选择JCR中8个学科301种期刊作为研究对象,分别计算每种期刊的JIPR8,并与其他几个跨学科期刊评价指标进行比较,检验JIPR8跨学科期刊评价的敏感度和稳定性,以及与其他跨学科期刊评价指标的相关性。[结果/结论]在选择的所有指标中,8个学科301种期刊JIPR8的变异程度最低,说明其用于跨学科期刊评价的稳定性最好;不同分区期刊(Q1、Q2、Q3和Q4)JIPR8的组间差异性较为明显,仅次于期刊影响因子百分位(journal impact factor pencentile,JIFP),表明其对优秀和一般期刊的区分度较好。认为JIPR8是一个非常理想的跨学科期刊评价指标。
[PURPOSE / Significance] Based on the percentile rank 8 (PR8) rankings of the eight cited citations, an attempt was made to construct a new interdisciplinary journal evaluation index: journal index for PR8 (JIPR8) And examined the impact of JIPR8’s interdisciplinary journals evaluation. [Method / Procedure] Select 301 journals of 8 disciplines in JCR as the research object, calculate JIPR8 of each journals separately and compare with other several interdisciplinary journals to evaluate the sensitivity and stability of JIPR8 interdisciplinary journals evaluation Sexuality, and relevance to other interdisciplinary journals. [Results / Conclusion] Of all the selected indicators, JIPR8 was the lowest in 301 journals of 8 disciplines, indicating that JIPR8 had the best stability for interdisciplinary journals. Different sub-journals (Q1, Q2, Q3 and Q4) JIPR8 showed more obvious differences between groups, second only to the journal impact factor pencentile (JIFP), indicating a good distinction between excellent and general journals. JIPR8 is considered as a very ideal interdisciplinary journal evaluation index.
