结合集成影响指标(I3)和h指数构成I3型多变量指标框架,获得发文矢量X=(X1,X2,X3)和引文矢量Y=(Y1,Y2,Y3)、集成发文指数I3X=X1+X2+X3和集成引文指数I3Y=Y1+Y2+Y3等多变量指标。实证研究显示:整体h核分布适用于评价学者,h核指数X1和Y1适用于评价大学的核心影响力,集成指数I3X和I3Y适合替代期刊影响因子JIF。多变量指标为学术评价提供了结合I3和h指数优势的多维视角,可丰富学术评价测度。图5。表4。参考文献18。附表3。
英文摘要:

    Since Garfield introduced the journal impact factor (JIF) and set up citation analysis,some scientometric indicators have been applied to academic evaluations. Then Hirsch proposed the h-index,which was rapidly accepted by the scientific community. This promoted the development of quantitative academic indicators. However,both JIF and h-index have their advantages and disadvantages. The Integrated Impact Indicator (I3) and the h-index can be combined into the I3-type framework,yielding the publication vectorX=(X1,X2,X3) and the citation vector Y=(Y1,Y2,Y3),the publication score I3X=X1+X2+X3 and the citation score I3Y=Y1+Y2+Y3,and alternative indicators,which could be developed to extend academic evaluation.

    The vector X and the score I3X represent the relative frequencies of the publications,while the vector Y and the score I3Y denote the relative frequencies of the citations. The h-based I3-type multivariate indicators provide multidimensional indicators:X1 measures publication score in the h-core (X1 and Y1 combination may measure core impact power); X2 measures publication score in h-tail; Yh=Y1+Y3 measures citation score in h-core; Y2 measures citation score in h-tail; I3X does total publication score,and I3Y does total citation score.

    The empirical studies reveal that the h-core distribution is suitable to evaluate scholars,and the X1 and Y1 are applied to measure core impact power of universities,and I3X and I3Y are alternatives of journal impact factor (JIF). The multivariate indicators provide a multidimensional view of academic evaluation with using the advantages of both the h-index and I3.

    The publication vector X=(X1,X2,X3) and the citation vector Y=(Y1,Y2,Y3) with their elements,as well as the publication score I3X=X1+X2+X3 and the citation score I3Y=Y1+Y2+Y3,contribute multivariate indicators for academic evaluation. 5 figs. 4 tabs. 18 refs. 3 attached tabs.
