基于因子分析法的科技期刊引文综合评价指标研究

目的 建立科技期刊引文综合评价指标函数,希望能对科技期刊引文综合评价工作提供参考意见。方法 选用IF、IF5、h指数、SJR、ES和SNIP为具有代表性的核心引文评价指标,通过对WoS数据库和Scopus数据库共有的1881种医学类期刊的这六大指标数值的因子分析。结果 找出对它们起支配作用的潜在影响因素：公因子F₁（平均影响力因子）和F₂（整体影响力因子）。在权衡这两个因素的基础上,构建了综合引文评价指标函数。结论 通过实例（选取专业期刊和综合期刊为样本）验证该综合指标能较好地消除期刊载文量对期刊综合影响力评价的影响。

Exp loration of com prehensive evaluation indicators of scientific journals based on factor analysis

[Purpose] To establish a formula of comprehensive evaluation indicator for scientific journals’citation w ith an attempt to offer some suggestions for comprehensive citation evaluation of scientific journals.[Methodology] We performed a factor analysis on the values of impact factor（IF）,5-year impact factor（IF5）,h index,SCImago journal rank（SJR）,Eigenfactor score（ES）and source normalized impact per paper（SNIP）of 1881 medical journals from WoS and Scopus databases.[Findings] We extracted two potential factors（also named principle components）influencing the six indicator values：F₁ named average impact factor and F₂ named overall impact factor.A formula of comprehensive evaluation indicator was constructed by weighing the two factors.[Conclusions] W ith special and comprehensive journals as samples,the comprehensive indicator was proved empirically being able to elim inate the adverse effect of published document number on the evaluation of scientific journal impact.
