摘要： 近年来国际上提出一种基于社会化网络的Altmetrics文献计量法,该方法能较准确地反映文献的社会影响力,并能弥补基于引用的传统文献计量方法时效性差、评价指标不全面、评价具有马太效应等缺陷。为在国内学术环境下实现Altmetrics方法的研究和应用,通过融合基于引用的传统指标与基于社会化网络的Altmetrics指标,对国内学术网络环境下的指标数据源进行统计和计算,结合Delphi赋权法和主成分分析赋权法求得各项影响力指标的权重因子,从而得到适应于国内学术环境的ALS综合计量模型。实验结果表明,主客观赋权法能互相弥补缺陷且所得结果更接近于真实情况,通过ALS综合计量模型求得的文献排名与传统引用量排名基本一致。

Abstract: In recent years,international researcher proposes an Altmetrics metrology method based on social network,which can accurately reflect social impact of literature and compensate the defects of traditional citation-based method that exists inherent defects of timeliness poor evaluation,non-comprehensive,and Matthew effect,etc..In order to realize the research and application of Altmetrics method in the domestic academic environment,this paper uses citation-based traditional index and social network-based Altmetrics index.Through the statistics and calculation of metrics sources in domestic academic network environment,and the integrated use of the Delphi and Principle Component Analysis(PCA) weighting method to get the weight factor of each influence factor,and then it designs an integrated literature metrology model suitable for domestic academic environment.The results show that,the subjective and objective weighting method can make up the defect and the result is closer to the real situation,the citation ranking calculated by ALS integrated metrology model is basically consistent with that by traditional citation-based method.
