A Comprehensive Analysis of the Pillar Anesthesiology Research. (A) Bar chart depicting each topic's most relevant preprocessed words along with their c-TF-IDF scores. (CS: Clinical Science, BS: Basic Science). (B) 2D plot illustrating the relationships between similar abstracts and their corresponding topics after dimensionality reduction of abstract embeddings using UMAP; colors denote topics as shown in 3A, while light grey denotes abstracts that have not been assigned to any topic. (C) Hierarchical clustering presenting the topics divided into two major clusters; the hierarchy is generated using the topic-term matrix (c-TF-IDF matrix), where smaller distances between c-TF-IDF representations indicate higher similarity between the topics.
