3种引文规范化指标RCR、CNCI和JNCI的相关性研究

Study on Correlations Among Three Standardized Evaluation Indices:RCR,CNCI and JNCI

[目的/意义]引文规范化指标作为一种新兴的评价指标,考虑了多种因素对论文引用的影响,从而在学术成果评价方面展示了较为突出的优势。研究不同引文规范化指标的关联性对于学术论文评价具有重要的意义。[方法/过程]本文选取InCites数据库中2018—2022年10种不同学科领域的论文作为研究样本,对这些论文的3种规范化指标(相对引用率RCR、学科规范化引文影响力CNCI和期刊规范化引文影响力JNCI)进行相关性分析,并对比分析了其中3个代表性学科领域的论文发表国家和研究机构的规范化指标。[结果/结论]研究结果表明,在这10种学科领域中,RCR、CNCI和JNCI指标两两之间呈现正相关;对于大多数学科领域,RCR与CNCI指标之间以及CNCI与JNCI指标之间相关程度均较高,而RCR与JNCI指标之间的相关程度相对较低;在不同学科领域中,国家或研究机构所对应的RCR和CNCI均值能够反映其在学科领域中的学术水平和学术影响力。本文的研究从一定程度上揭示了RCR、CNCI和JNCI指标在不同学科领域中评价论文学术影响力的差异和关联性。

[Propose/Significance]As an emerging type of citation evaluation index,the standardized evaluation index considers the influences of multiple factors on the paper citations,and therefore exhibits the remarkable advantage in the evaluation of academic achievements.It is of great significance for the evaluation of academic papers to investigate the correlations among different standardized evaluation indices.[Method/Process]In this paper,papers in ten academic areas from the InCites database in 2018—2022 were selected as the research samples,and the correlation analyses for relative citation ratio(RCR),category normalized citation impact(CNCI)and journal normalized citation impact(JNCI)of these papers.The study further made comparative analyses on the RCR and CNCI of papers from different countries and research institutes was further made.[Result/Conclusion]The results show that in ten academic areas,there exist a positive correlation among three indices.For most of areas,both RCR vs CNCI and CNCI vs JNCI have the strong positive correlations,while the RCR vs JNCI has a relatively weak correlation.For different academic areas,the average RCR and CNCI of country or research institution can reflect its academic level and academic influence.The current study to a certain extent revealed the differences and correlations among RCR,CNCI and JNCI in the evaluation of the academic influence of papers in different academic areas.
