Abstract:

[Purposes] This paper aims to probe into the interdisciplinary research intensity of academic journals and articles and its relationship with academic impact. [Methods] This article took the articles in information science and library science included in Web of Science database in 2013 and the journals on which they were published as the research objects. The Brillouin index (BI) of each article and journal was calculated. The cited frequency was used to measure the academic impact of articles, while the impact factor, 5-year impact factor, eigenfactor, and article influence score were adopted to characterize the academic impact of journals. SPSS statistical software was employed to analyze the relationship between BI and cited frequency of articles and the relationship of BI with the evaluation indicators of journals. [Findings] The BI of articles is in a highly significantly positive correlation with the cited frequency. Journal BI is positively correlated with the total cites, impact factor, article influence score, non-self-citing impact factor, and other indicators of journals, especially the 5-year impact factor. [Conclusions] The stronger the interdisciplinary research intensity of articles and journals in information science and library science, the higher the academic impact.

摘要：

【目的】 探讨学术期刊和论文跨学科强度与学术影响力的关系。【方法】 选取Web of Science数据库中2013年Information Science and Library Science(图书情报学)论文及其所属期刊为研究对象,分别计算每篇论文的布里渊指数(Brillouin Index,BI),以被引频次表征论文的学术影响力,以影响因子、5年影响因子、特征因子及论文影响分值表征期刊的学术影响力,对BI与论文被引频次和期刊评价指标进行统计分析。【结果】 2013年图书情报学论文的BI和被引频次呈较强的正相关关系,差异有统计学意义。图书情报学期刊的BI与期刊总被引频次、影响因子、特征因子和论文影响分值均呈正相关,且与5年影响因子相关度最高。【结论】 图书情报学领域论文和期刊的跨学科性越强,越容易获得较高的影响力。
