• Abstract
  • The number of publications in biomedicine and life sciences
  • has rapidly grown over the last decades,
  • with over 1.5 million papers now published every year.
  • This makes it difficult to
    • keep track of new scientific works and
    • to have an overview of the evolution of the field as a whole.
  • Here we
    • present a 2D atlas of the entire corpus of biomedical literature, and
    • argue that it provides
      • a unique and
      • useful overview
    • of the life sciences research.
  • We base our atlas on the abstract texts of
  • 21 million English articles from the PubMed database.
  • To embed the abstracts into 2D, we use
    • a large language model PubMedBERT, combined with
    • t-SNE tailored to handle samples of our size.
  • We use our atlas to study
    • the emergence of the Covid-19 literature,
    • the evolution of the neuroscience discipline,
    • the uptake of machine learning, and
    • the distribution of gender imbalance in academic authorship.
  • Furthermore, we present an interactive web version of our atlas that
    • allows easy exploration and
    • will enable further insights and facilitate future research.
