单篇论著学术迹与影响矩比较研究

A Comparative Study of Academic Trace and Impact Torque on Single Publication

本文对新近提出的学术迹和影响矩指标应用于单篇论著的评价效果进行比较研究,以JASIST 2005—2014年间发表的25篇高被引论文和ASTROPHYSICAL JOURNAL 2011—2014年间发表的24篇高被引论文为两个样本集,研究学术迹和影响矩相对于总被引数和h指数等学术评价指标的异同,发现各指标排序既具有一定相关性,也呈现出一定独立性,说明这些指标均有独立存在价值,而学术迹和影响矩能提供更全面的测度信息。图3。表6。参考文献25。附录2。

There have been many academic indicators, but few indicators can be applied to appraise single publication, in which counting total citations becomes the simplest approach. Recently, academic trace and impact torque have been proposed and applied, where academic subjects such as authors and institutes are considered, and academic objects particularly single publications are also concerned. In the article, authors compare and analyze the effects of academic trace and impact torque in the applications for single publications, on which further related studies are expected. The authors focus on comparing academic trace and impact torque, with referring to total citation and citing h-index. The academic trace originates from mathematical trace of academic matrix and is determined by 5 parameters： total citing papers P, citing h-index h, totalciting citations C, uncited citing papers Pz and citations in hcore Ch. The impact torque refers to physical torque, which is defined as the multiply of impact author-force A and impact time-span D. Two datasets 25 highly cited papers in JASIST 2005-2014 and 24 highly cited ones in ASTROPHYSICAL JOURNAL 2011-2014 are used to compare the effects of academic trace and impact torqueand to reveal their correlations and differences. It is concluded that academic trace and impact torque possess independences and correlations in comparing with pure citations and citing h-index. When the total citations and citing h-index cannot differentiate the impacts of single publica- tions, academic trace and impact torque provide better differentiation. On overall effects, academic trace and impact torque work better than pure citations and citing h-index, and academic trace works better than impact torque. Comparing with pure citations and citing h-index, the new indicators, academic trace and impact torque, display both independences and correlations and thus supply rich measuring information and new appraising view for application. 3 figs. 6 tabs. 25 refs. 2 appendixes.
