A natural language processing–driven map of the aging research landscape
Figure 5. Temporal evolution of BoA research clusters. (A) UMAP of vectorized documents distributed in decades. (B) Evolution of BoA cluster proportions, each line represents the 5-year moving average of each cluster proportion (1975-2023). (C) Mean publication year of the documents in each cluster. (D) Cosine similarity trend analysis across clusters, results represent the slope of the 5-year moving average of the changes in cosine similarity within each cluster (1975-2023).
