摘要
[目的/意义]通过对引文学科多样性和论文影响力之间相关关系进行分析,以探究学科交叉程度能否促进论文影响力的提升。[方法/过程]采集图书情报、医学信息学以及运筹管理三个学科领域2010-2017的论文元数据,分别用跨领域引用指数和香农熵量化学科多样性程度,采用论文总被引次数和年均被引次数表示论文学术影响力,用论文总使用次数和年均使用次数表示论文社会影响力;通过Spearman秩相关分析对引文学科多样性与论文影响力之间的关系进行研究。[结果/结论]医学信息学为三个学科中引文学科多样性最高的学科,三个学科的引文学科多样性随时间呈现增长趋势;跨领域引用指数与被引次数和使用次数相关关系极弱,而香农熵与被引次数和使用次数均具有较强的正相关,且在0.01置信度水平下均有统计学意义。
[Purpose/Significance]This paper analyzed the relationship between diversity of references and impact of paper to explore whether diversity of references can promote the improvement of impact of paper.[Method/Process]Firstly,the metadatas of papers in information science and library science,medical informatics,and operation research and management science ranging from 2010 to 2017 were collected.Secondly,Citation outside category and Shannon entropy were used to represent diversity of references,and citation counts and normalized citation counts were used to represent academic impact of paper.Moreover,usage and normalized usage were used to represent social impact of paper.Finally,the authors used Spearman rank correlation analysis to study the relationship between diversity of references and impact of paper.[Result/Conclusion]The results show that medical informatics is the discipline with the highest diversity of references among the three disciplines,and diversity of references in the three disciplines has an increasing trend.In addition,in the three disciplines,Citation outside category has a weak correlation with citation counts and usage of the paper,while Shannon entropy has a strong positive correlation with citation counts and usage of the paper,which shows statistical significance at the 0.01 level.
