Scientific Research Status in Vietnam during the period 2019-2023 and Directions for Medical Research

Abstract

This study analyzes the trend of scientific publication in Vietnam in the period 2019-2023, focusing on the relationship between the number of publications, the number of citations, and the JNCI (Journal Normalized Citation Impact) index. Data were collected from the InCites database of Web of Science, then processed and analyzed to extract results of important scientific significance. One of the analysis results shows that, although a few research institutions have a low number of publications, their JNCI index is high. On the contrary, most of the units exhibit a higher number of publications, albeit with a lower JNCI index. The research method combines traditional statistical tools and modern clustering algorithms such as K-means clustering and DBSCAN. In addition, word cloud techniques are used for visual illustration, which aids in a deep analysis of each research group’s characteristics. The results show that institutions with international collaboration and publications in journals in groups Q1 and Q2 have significantly higher levels of influence, as demonstrated by the number of citations and superior JNCI index. In particular, the fields of medicine and health sciences stand out due to international attention and the urgency of research in the context of the COVID-19 pandemic. These findings emphasize the role of international collaboration strategies and publications in prestigious scientific journals to enhance the quality and influence of Vietnamese scientific research on the world stage.
