Contents

The volume of research literature on critical care has experienced exponential growth over the past two decades, rendering traditional bibliometric methods inadequate for analyzing such vast datasets. This necessitates the employment of machine learning (ML) and natural language processing (NLP) techniques to investigate research trends and uncover knowledge gaps. In this study, we utilized uniform manifold approximation and projection (UMAP) and the BERTopic algorithm to explore the differences and similarities between open-access database studies and traditional intensive care studies. Our objective is to identify existing knowledge gaps and explore ways in which they can complement each other.
