摘要：

目的 分析Web of Science(WoS)数据库中信息科学与图书情报学论文的文献级别用量指标(使用次数)与被引频次的分布情况及两者之间的相关性,以揭示论文使用与被引的规律及相关关系。方法 收集2013—2015年WoS数据库收录的信息科学与图书情报学领域被引频次TOP 5%、使用次数TOP 5%论文的数据,分析文献类型以及被引频次和使用次数在不同年度的情况及相关性。结果 被引频次TOP 5%、使用次数TOP 5%以及两者重合文献的主要类型均为Article。2013—2015年发表的论文的使用次数(180 d)和被引频次均差异显著(P值均小于0.05),前者逐年增加,后者逐年减少;使用次数、使用次数(180 d)和被引频次弱相关(P值均小于0.05);各年度中除2015年外均有相关性。结论 引文时间窗口期越长,论文被引频次越高,一定时间内学者们更倾向于使用较新的文献;揭示了论文使用与被引之间的相关性,这种相关性和引文时间窗口期有关。

Abstract:

[Purposes] This paper aims to analyze the distribution and correlation between usage count and citation frequency of li-teratures of information science and library science which are searched in Web of Science (WoS) database, in order to reveal the regularity and the relation between them.[Methods] We searched the citation frequency and the usage count of TOP 5% literatures of information science and library science which were published from 2013 to 2015 in WoS. We analyzed literature types, citation frequency and usage count in different years and their correlation.[Findings] It shows that the article is the main literature type in the citation frequency TOP 5%, usage count TOP 5% and overlapping literatures. Usage count (180 days) and citation frequency have significant differences among 2013—2015 (both P<0.05). The usage count increases every year, and annual performance of the citation frequency is in the contrary. There are weak associations between usage count and usage count (180 days) with the citation frequency. In addition to 2015, there are correlations in 2013 and 2014.[Conclusions] It reveals that the longer the citation time window of citation is, the higher the citation frequency is. Scholars tend to use more new literatures in 180 days. In addition, it also reveals that there is the correlation between citation frequency and usage count, and the correlation is related to the time window of citation.
