摘要
当前学界关于论文的标准化评价指标多从学科角度分类,忽视论文主题的多样性且每一主题概率不同等问题.文章在CNCI(Category Normalized Citation Impact,学科规范化影响力)指标基础上,结合主题模型、引文分析等方法提出构建可横向比较的普适性指标GTNI(General Topic Normalized Citation Impact,基于主题模型的论文标准化影响力),以提高学术论文评价的科学性.GTNI是对论文每一主题被引进行标准化并综合而获得的指标.通过理论分析、指标构建、实证研究和对比检验,表明GTNI指标在论文影响力评价方面具有较好的效果,且具有应用前景.
Abstract
At present,the normalized evaluation indicators of papers are classified from the perspective of disci-pline,ignoring the diversity of topics and the different degrees of topics involved.Based on the index of CNCI(Cat-egory Normalized Citation Impact),combining with the methods of topic model and citation analysis,this paper proposes to construct a cross-comparable General Topic Normalized Citation Impact(GTNI),in order to improve the scientific evaluation of academic papers.GTNI is an indicator that is normalized and synthesized for each topic in a paper.Through theoretical analysis,indicator construction,empirical study and comparative test,it shows that GTNI has a good effect in the paper impact evaluation,and has a variety of application prospects.
