特征因子实证研究——以生物学和经济学外文期刊为例

Empirical Study of Eigenfactor —Taking the Case Study of the Biology and Economics of Foreign Periodicals

JCR中收录的期刊范围近8 000余种,很多期刊几乎不引用其他学科的期刊,也不被其他学科的期刊引用,因此基于全部期刊范围的特征因子分值不利于不同学科的期刊比较,尤其是那些封闭性较强的学科。因此,在特征因子模型和算法的基础上,以2008-2010三年JCR收录的生物学和经济学的外文期刊为例,在学科范围内利用自编软件计算出它们的特征因子值,,探析期刊排名变化产生的原因和影响因素,验证小学科期刊特征因子在生物学和经济学期刊内的有效性。

JCR journals included nearly 8 000 species, many journals hardly cited journals in other disciplines, nor cited journals in other disciplines, Therefore, based on the characteristics of the entire range of journals factor scores is not conducive to compare journals in different disciplines, especially those who closed strong discipline. Therefore, this article on the basis of the Eigenfactor factor model and algorithm, taking the cited data of biology and economics periodicals JCR collected , making use of the software to calculate their Eigenfactor within the scope of subject,discusses the causes of journal rankings change, verifying the effectiveness of Eigenfactor in little discipline journal within the biology and economics journals.
