基于PageRank的机构科研影响力评价

摘要

The paper puts forward the method for evaluation on the scientific influence of institution based on PageRank algorithm,configures the initial weight of each institution based on the problems of dividing equally the webpage weight number in the classical PageRank algorithm and cited frequency of the application chapter,constructs the network matrix cited by institution through the citation situation of medical SCI papers published by partial colleges and universities in 2015,respectively calculates the PageRank values of institution when self-citation is excluded or included,and conducts comparative analysis on the sequence of cited frequency indicators of the institution as well as H index.This method can be used to evaluate scientific influence of institution from two dimensions of quality and quantity.%提出基于PageRank算法的机构科研影响力评价方法,针对PageRank经典算法中存在的平分网页权值问题,应用篇均被引频次来配置利用各机构的初始权重.应用2015年部分高校发表的医学类SCI论文的被引用情况构建机构引用网络矩阵,分别计算去除自引和包含自引的机构PageRank值,与机构被引频次及H指数的排序进行对比分析.该方法可同时从质量和数量两个维度评价机构科研影响力.
