SJR指标:一种衡量期刊科学声望的新指标

The SJR indicator: A new indicator of journals' scientific prestige

Borja Gonzalez-Pereira, Vicente Guerrero-Bote, Felix Moya-Anegon

摘要:

本文提出了一种基于引文权重方案和特征向量中心性的期刊科学声望指标SJR,用于对Scopus等复杂异构的引文网络中的学术期刊进行排名。它的计算方法进行了描述,并在Scopus 2007数据集上实施该指标后的结果与一般和特定科学领域内的临时期刊影响因子进行了比较。结果表明,SJR指标和JIF分布拟合良好的幂律分布,这两个指标是强相关的,虽然也有重大变化的排名。有一个可观察到的一般趋势,可能表明,SJR指标值降低了某些JIF值,其引用率大于其科学影响力。

英文摘要:

This paper proposes an indicator of journals' scientific prestige, the SJR indicator, for ranking scholarly journals based on citation weighting schemes and eigenvector centrality to be used in complex and heterogeneous citation networks such Scopus. Its computation methodology is described and the results after implementing the indicator over Scopus 2007 dataset are compared to an ad-hoc Journal Impact Factor both generally and inside specific scientific areas. The results showed that SJR indicator and JIF distributions fitted well to a power law distribution and that both metrics were strongly correlated, although there were also major changes in rank. There was an observable general trend that might indicate that SJR indicator values decreased certain JIF values whose citedeness was greater than would correspond to their scientific influence.
