Extraction and validation of scientific data for the identification of publications in open access journals

This work aims to identify articles published in open access journals registered in the Lattes Platform curricula. Currently, the curricular data from the Lattes Platform has been the source of several studies that adopt bibliometric metrics to understand scientific evolution in Brazil. However, when registering a publication in a curriculum, only basic information from the magazine is informed. Therefore, to quantify the publications made in open access journals, a strategy is proposed that uses data from the Directory of Open Access Journals, validating the publications and, thus, obtaining a process that allows identifying which publications were made in this communication format. Therefore, using the proposed methodology, which has a low computational cost, it was possible to quantify in an unprecedented way the publications of Brazilians in open access journals registered in the curricula of the Lattes Platform. In addition, having the authors' data of the publications, it was possible to understand how these authors are geographically distributed in the country, what their areas of operation are and how they have published the results of their research in open access. It is noteworthy that they are generally published in Portuguese and English. Over the last few years, the representativeness of publications in open access journals has increased.
