学术期刊机构指数AAI与影响力关系研究——以图书馆情报文献学期刊为例

Research on the Relationship between AAI and Influence of Academic Journal——Taking Library and Information Science Journals for Example

[目的/意义]研究机构指数(Author Affiliation Index)与主要文献计量指标关系具有重要意义,可以进一步推进机构指数的应用。[方法/过程]本文以图书馆情报与文献学期刊CSSCI期刊为例,基于中国知网CNKI引文数据库,计算出各期刊的机构指数,并采用相关系数、偏最小二乘法对其与影响因子、h指数、被引次数的关系进行了分析。[结果/结论]研究发现:机构指数与影响因子正相关但拟合优度不高,与h指数、被引频次不相关,说明机构指数能够提供除期刊影响力以外的其他信息;机构指数具有较好的统计学评价指标特征,可以作为期刊评价指标;机构指数的相关研究有待进一步加强。

[Purpose/Significance]AAI(Author Affiliation Index),a bibliometric indicator proposed by American scholars but lack utilization in China,is necessary to study its characteristics and the relationship of bibliometrics indexes.[Method/Process]Based on the database of CNKI(China National Knowledge Infrastructure),this paper,taking the CSSCI journal of Library and Information Sciences for example,calculated the AAI of each journal and analyzed the relationship between AAI,impact factor,h-index and citation frequency through the method of correlation coefficient and partial least square.[Result/Conclusion]The study showed that:AAI was positively related to the impact factor but had a low fitting degree,and was not related to the h-index and the frequency of citations.It explaind that the AAI could provide other information than the journal influence;the AAI had the better statistical evaluation index characteristics which could be used as evaluation indicators for periodicals;the relevant research on AAI needed to be further strengthened.
