Autocitação de periódico no índice-h5 de periódicos Ibero-Americanos
Palavras-chave:
Bibliometria, Google Scholar Metrics, Periódicos Ibero-americanos, Autocitação de periódicoResumo
Este estudo analisa a autocitação de periódicos a partir do índice-h5. Foi utilizada a ferramenta bibliométrica Gsm_hdata para identificar 4049 periódicos ibérico-americanos indexados simultaneamente no Latindex e no Google Scholar Metrics. As autocitações foram identificadas, as taxas de autocitação por país e área de pesquisa foram calculadas e o índice-h5 foi recalculado sem autocitações (índice-hs5). Quase 40% dos periódicos não registraram autocitações, especialmente aqueles com índice-h5 menor que 5. A taxa média geral de autocitação foi de 3,6%. Entre os 1859 periódicos mais citados e com pelo menos uma autocitação, a taxa foi de 4,8%, taxa inferior à de pesquisas baseadas no Fator de Impacto. Periódicos de Engenharia, de Ciências Exatas e Naturais e de Ciências Agrárias apresentaram as maiores taxas de autocitação, enquanto periódicos de Ciências Sociais e Humanas as mais baixas. Periódicos com taxas excessivas (outliers) foram identificados em todas as áreas. Estes resultados sugerem que a exclusão prévia de autocitação de periódicos no cálculo do h5-índice não é necessária. No entanto, é recomendado monitorar periódicos com taxas excessivas para evitar distorções nos procedimentos de avaliação de impacto baseados no h5-índice do Google Scholar Metrics.
