Research on the Normalized Impact Index of Per Paper Based on Topic Model——A New Paper Normalized Impact Indicator GTNI
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.
