Purpose

This study distinguishes the academic influence of different papers published in journals of the same subject or field based on the modification of the journal impact factor.

Design/methodology/approach

Taking SSCI journals in library and information science (LIS) as the research object, the authors first explore the skewness degree of the citation distribution of journal articles. Then, we define the paper citation ratio as the weight of impact factor to modify the journal impact factor for the evaluation of papers, namely the weighted impact factor. The authors further explore the feasibility of the weighted impact factor in evaluating papers.

Findings

The research results show that different types of skewness exist in the citation distribution of journal papers. Particularly, 94% of journal paper citations are highly skewed, while the rest are moderately skewed. The weighted impact factor has a closer correlation with the citation frequency of papers than the journal impact factor. It resolves the issue that the journal impact factor tends to exaggerate the influence of low-cited papers in journals with high impact factors or weaken the influence of high-cited papers in journals with low impact factors.

Originality/value

The weighted impact factor is constructed based on the skewness of the citation distribution of journal articles. It provides a new method to distinguish the academic influence of different papers published in journals of the same subject or field, then avoids the situation that papers published in the same journal having the same academic impact.

加权影响因子:基于被引率的论文评价指标

目的

本研究根据期刊影响因子的修改,区分同一学科或领域期刊发表的不同论文的学术影响力。

设计/方法/方法

作者以SSCI期刊图书馆与信息科学(LIS)为研究对象,首先探讨期刊文章引文分布的偏度。然后,我们将论文引用率定义为影响因子的权重,以修改期刊影响因子对论文的评价,即加权影响因子。作者进一步探讨了加权影响因子在评价论文中的可行性。

发现

研究结果表明,期刊论文的引文分布存在不同类型的偏态。特别是,94% 的期刊论文引用是高度偏斜的,而其余的则是中度偏斜。与期刊影响因子相比,加权影响因子与论文被引频次的相关性更密切。它解决了期刊影响因子倾向于夸大低被引论文对高影响因子期刊的影响或弱化高被引论文对低影响因子期刊的影响的问题。

原创性/价值

加权影响因子是根据期刊文章引用分布的偏度构建的。它提供了一种新的方法来区分发表在同一学科或领域的期刊上的不同论文的学术影响,从而避免了在同一期刊上发表的论文具有相同学术影响的情况。
