Abstract

Abstract: It aims to analyze journal self-citation in Ibero-American journals from the h5-index of the Google Scholar Metrics. The bibliometric tool Gsm_hdata was used to identify 4049 Ibero-American journals indexed simultaneously in Latindex and Google Scholar Metrics. Self-citations were identified, self-citation rates by country and research area were calculated, and the h5-index was recalculated without self-citations (hs5-index). No self-citations were identified in almost 40% of the journals, especially those with an h5-index lower than 5. The overall average self-citation rate was 3.6%. Among the 1859 most cited journals with at least one self-citation, the rate was 4.8%, lower than that of research based on the Impact Factor. Journals of Engineering, Exact and Natural Sciences, and Agricultural Sciences had the highest self-citation rates, while Social Sciences and Humanities journals presented the lowest. Journals with excessive rates (outliers) were identified in all areas. These results suggest that the prior exclusion of journal self-citations in the calculation of the h5-index is not necessary. However, monitoring journals with excessive self-citation rates is recommended to avoid distortions in impact assessment procedures based on h5-index of Google Scholar Metrics.

伊比利亚-美洲期刊h5指数的期刊自引

摘要:利用Google Scholar Metrics的h5指数分析伊比利亚-美洲期刊的期刊自引情况。使用文献计量工具Gsm_hdata识别在Latindex和Google Scholar Metrics中同时被索引的4049种伊比利亚-美洲期刊。确定自引，计算按国家和研究领域划分的自引率，并重新计算不含自引的h5指数(hs5-index)。近40%的期刊没有发现自我引用，尤其是那些h5指数低于5的期刊。总体平均自引率为3.6%。在被引次数最多且至少有一次自引的1859种期刊中，自引率为4.8%，低于基于影响因子的研究。工程、精确与自然科学、农业科学期刊的自引率最高，而社会科学和人文科学期刊的自引率最低。在所有领域都发现了高比率(异常值)的期刊。这些结果表明，在计算h5指数时不需要预先排除期刊自引。然而，建议监测自引率过高的期刊，以避免基于Google Scholar Metrics的h5-index影响评估程序的扭曲。
