Crossed H-Index: uma ferramenta para investigar a autopromoção acadêmica em periódicos na base do Google Acadêmico

Abstract

This research presents a refined version of the bibliometric H-Index from Google Scholar Metrics (GSM) without self-citations, the Crossed H-Index. The process of extracting the author’s self-citations consists of comparing the names of the authors of the articles that compose the H-Index with the names of the authors of the publications that cites them, and verifying whether the citation of an article is from the same journal in which the article is published. A technological solution was implemented in order to democratize the consultation of the Crossed H-Index, available on the website: http://palmas.uft.edu.br/crossed-h-index. This work also has an analysis of the self-citations of 522 journals in the area of knowledge of Applied Social Sciences, in the subarea of Urban and Regional Planning/Demography. Of these, 64 journals obtained a reduction in their H-index, in relation to the Crossed H-Index, greater than the sum of the mean (13.89%) with the standard deviation (11.48%) in relation to the evaluated group. These 64 journals indicate a possible abuse of self-citations, considering that the impact of self-citations on their H-Index is beyond the standard of journals in the same group of knowledge area.
