Abstract

Objective. To analyze the visibility and online attention of scientific productions deposited in Brazilian Institutional Repositories, using altmetrics. Method. The study adopts a quantitative descriptive approach, analyzing the online visibility and attention of productions deposited in institutional repositories based on altmetric metrics. The research was conducted in two main stages: (i) mapping and selection of institutional repositories and (ii) data collection and altmetric analysis. Results. he distribution of the institutions that maintain the IRs is made up of 81 repositories linked to public universities, 44 to private institutions, 33 to public research institutions and 26 to Federal Institutes of Education, Science and Technology. However, only 11 of these repositories, corresponding to 42.3%, have attention data available in Altmetric Explorer. Conclusions. The analysis of online attention revealed significant disparities between the institutional repositories examined. UNESP's IR stood out with 86.5% of the total number of mentions in the corpus analyzed. The social network X (formerly Twitter) is the most used social network for sharing the publications made available by the IRs. The results show that although Brazilian institutional repositories play an important role in the dissemination of scientific knowledge, their online attention and visibility on social media is still limited.

She has been serving as Librarian-Documentalist at the Federal Institute of Minas Gerais (IFMG) since 2016 and has coordinated the IFMG Library Network since 2018. Responsible for the implementation, management, and evaluation of the IFMG Institutional Repository, developing policies for the visibility and preservation of scientific output. She previously worked as Librarian at the Fire Department Academy of Minas Gerais (2010–2016). She has consolidated experience in the following areas: academic library management; information literacy; marketing of information units; implementation and management of institutional repositories; web-based scientific metrics; preparation of libraries for evaluation processes conducted by the Brazilian Ministry of Education (MEC); scholarly communication; and open science. Her research focuses on the open science ecosystem, particularly on the use of alternative metrics (altmetrics) and webometrics to analyze engagement, impact, and visibility of Brazilian institutional repositories. She also conducts studies on indicators of scientific visibility, digital presence of repositories, social impact metrics of science, and online attention communities.
