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.
