摘要:

【目的】采用H指数和二八法则基于文献的被引频次来划分出期刊文献的核心区,为科研工作者提供一种把握研究热点的新方法。【方法】以WoS中收录的84种的图书情报学期刊15592篇文献为研究样本,并采用H指数和二八法则基于文献的被引频次来划分出期刊文献的核心区。【结果】采用二八法则划分文献核心区,其核心区文献量占总文献量为6.12%~48.61%,均值为33.81%;而采用H指数划分文献核心区,其核心区文献量占总文献量为0.56%~26.09%,均值为7.80%。对学科采用二八法则划分文献核心区,其核心区文献量占总文献量80%的文献量为38.05%;采用H指数划分文献核心区,其核心区文献占总文献量为0.67%。核心区文献篇均被引频次为H指数划分大于二八法则划分。【结论】采用H指数划分期刊文献核心区比二八法则更具集中趋势,故而H指数能更好地划分出期刊文献核心区。

Abstract:

[Purposes] This paper uses H-index and the 20/80 principle based on citations to find the core of journals and provide a new method to find research hotspot for scientists.[Methods] The Stratification mechanism for scientific journals in academ ic dimension is an objective phenomenon,and high cited papers often have the trend of concentration.This paper takes15592 papers of 84 journals of Information Science and Library Science(LIS)from WoS as a case,and uses H-index and the 20/80 principle based on citations to find nucleus of journals.[Findings] The results show thatnucleus of journals’ articles takes6.12% ~48.61%in the total articles of journals and the average is33.81%by 20/80 principle;the nucleus of journals’ articles is0.56% ~26.09%and the average is 7.80%by H-index.The nucleus of journals;articles is 38.05%by 20/80 principle and the nucleus of journals’ articles accounting for the total articles of all LIS journal is 0.67%by H-index.The average citations of nucleus papers found by H-index aremore than those found by 20/80 principle.[Conclusions] The nucleus of journals found by H-index ismore concentrated than that found by 20/80 principle,so the H index may be better to find the nucleus of journals than 20/80 principle.
