The Map of Science includes hundreds of millions of scholarly publications from around the world, algorithmically organized into over 91,000 research clusters. These clusters are groups of papers that cite each other a lot and feature similar text in their titles and abstracts — typically reflecting shared subject matter, language of publication, or other important characteristics. By filtering clusters according to growth, key topics, countries, and other characteristics, users can quickly pinpoint scientific trends and communities. The Map of Science — originally launched in October 2021 and updated in April 2026 — is maintained by CSET’s data team and free to all on our Emerging Technology Observatory.
