【摘要】：[目的/意义]比较JCR新增期刊评价指标影响因子百分位与SNIP的跨学科评价效力。[方法/过程]以SCI收录的4种学科为基础,对学科内和学科间的各期刊影响因子百分位和SNIP做Spearman等级秩相关分析,同时将4种学科的期刊按JCR分区分组,即Q1区组、Q2区组、Q3区组和Q4区组,对各组期刊的影响因子百分位和SNIP分别做Spearman等级秩相关分析。[结果 /结论]影响因子百分位与SNIP在学科内呈显著正相关(均为P=0.000),相关系数平均为0.826。影响因子百分位与SNIP在学科间亦呈显著正相关,相关系数为0.817(P=0.000)。分组比较结果示,在Q1区组、Q2区组和Q4区组影响因子百分位和SNIP均呈显著正相关(均为P0.05),但在Q3区组,影响因子百分位和SNIP不相关(P=0.185)。使用影响因子百分位与SNIP在学科内及学科间的期刊排序均是一致的;但在跨学科评价中,在影响力较大的一半期刊中,影响因子百分位与SNIP的期刊排序结果一致性更强,在影响力最小的1/4期刊中,影响因子百分位与SNIP的期刊排序结果也一致,在影响力中等偏下的一部分期刊中,影响因子百分位与SNIP的期刊排序没有相关性。
[Abstract]:Objective / significance: to compare the percentile of influence factors of JCR new periodical evaluation index with the effectiveness of interdisciplinary evaluation of SNIP. [method / process] Spearman rank correlation analysis was made on the percentiles of influence factors and SNIP of each journal within and between disciplines based on the four disciplines included in sci. At the same time, the journals of four subjects were grouped according to JCR. Q1, Q2, Q3 and Q4, respectively. Spearman rank correlation analysis was performed on the percentile of influencing factors and SNIP in each group. [results / conclusion] significant positive correlation was found between the percentile of influencing factors and SNIP (P < 0. 000), the average correlation coefficient was 0. 826. There was also a significant positive correlation between the percentile of influencing factors and SNIP among subjects, and the correlation coefficient was 0.817 ~ 0.000. The results showed that there was a significant positive correlation between the percentile of influencing factors and SNIP in Q1 / Q2 and Q4 groups (both P0.05A), but in Q3 group, there was no correlation between the percentile of influencing factors and SNIP (P0. 185). Using the percentile of influence factor is consistent with the ranking of journals within and among subjects by SNIP, but in the half of the journals with greater influence, the results of ranking of periodicals with influence factor are more consistent with those of SNIP, but in the cross-disciplinary evaluation, the results of periodical ranking are more consistent between the percentile of influence factors and those of SNIP. In the least influential quarter of journals, the percentile of influence factor is the same as the ranking result of SNIP, but there is no correlation between the percentile of influence factor and the ranking of SNIP in some journals with moderate influence.
