Abstract

The goal of this study was to investigate the dynamics of two journals indicators (Cited Half-life and Citing Half-life) in the case of incomplete or inaccuracy data in the Journal Citation Reports. A detailed analysis of these data for the CdHL and CgHL indicators for 1997–2018 was performed. The previously formulated similarity hypothesis on journal distribution by half-life period was clarified. Methods for determining the weighted average values of half-life indicators were developed in detail. The test of the similarity hypothesis had identified the time frame within which its objectivity was certain. Results of our study revealed that the dynamics of half-life indicators were positive; moreover, and these dynamics are much more pronounced for permanently retentive journals, i.e., journals that were present in the JCR during the entire 22-year study period.

在期刊引文报告中数据不完整的情况下，科学期刊的半衰期计算

摘要

这项研究的目的是调查两种期刊指标（被引半衰期和被引半衰期）在“期刊引文报告”中数据不完整或不准确的情况下的动态。对1997-2018年CdHL和CgHL指标的这些数据进行了详细分析。阐明了先前针对半衰期分配期刊制定的相似性假设。详细开发了确定半衰期指标加权平均值的方法。对相似性假设的检验已经确定了确定其客观性的时间范围。我们的研究结果表明，半衰期指标的动态是积极的。而且，对于永久保留期刊，这些动态更为明显，例如，
