不同水平特征因子与文献计量指标的关系研究

Eigenfactor Score and Other Informetrics Indicators at Different Levels

为研究不同特征因子分值条件下,其与其他文献计量指标的关系,基于JCR 2009年电气电子期刊数据,采用分位数回归进行研究。结果表明,对于特征因子分值较低的期刊,论文影响分值、总被引频次与特征因子呈较低正相关,即年指标与特征因子无关,5年影响因子、被引半衰期与特征因子呈较低的负相关。载文量只在特征因子分值较低时与它呈正相关关系,其他情况无关。对于特征因子分值较高的期刊,论文影响分值与特征因子呈较高的正相关,即年指标与其呈较高的负相关,其他情况特点不明显。研究发现,特征因子分值的引入有利于期刊提高学术质量,但对于其他学科的情况有待进一步研究。

This paper studies eigenfactor score（ES） and other informetrics indicators at different levels based on quantile regression and data of electrical ＆ electronics engineering JCR 2009 from Thomson Reuters. The results show that when the eigenfactor score is at lower level, article influence score and total cites has lower correlations with ES, immediacy index has no correlations with ES, 5-Year impact factor and cited half-life have little negative correlation with ES. Articles only has correlation with ES when the eigenfactor score is at lower level. When the eigenfactor score is at higher level, article influence score has lower correlation with ES, immediacy index has little negative correlation with ES. Eigenfactor score helps to enhance the quality of academic journals. The correlation of ES to other informetircs indicators needs to be studied further more.
