OA publications in Vietnamese E&T Universities

This study analyzes trends, research domains, and emerging themes in open access publishing at Vietnamese universities specializing in engineering and technology. Based on a bibliometric analysis of Scopus-indexed publications from 2013 to 2023, the study aims to identify key characteristics of open access publishing and its role in enhancing research dissemination and collaboration in Vietnam. The findings indicate a sharp increase in the number of open access publications after 2018. The three most prominent subject areas are Engineering, Computer Science and Agricultural-Biological Science. The research topics covered in open access publications are diverse, including climate change, biodiversity, sustainable development in Vietnam, machine learning, deep learning, materials science, biomedical engineering, ect. The analysis is limited to English-language publications indexed in Scopus. Nevertheless, the results offer a clear and valuable overview of the current state of open access publishing within Vietnam's engineering and technology universities. They also suggest pathways for improving research accessibility, increasing visibility, and strengthening international collaboration through open access strategies.
