Map of Science

ETO's Map of Science collects and organizes the world’s research literature, revealing key trends, hotspots, and concepts in global science and technology.

Map of Science includes hundreds of millions of scholarly publications from around the world, organized into over 91,000 research clusters. Filter clusters by scientific discipline, emerging tech subject, predicted growth or other characteristics to pinpoint research trends and hotspots. The Map runs on bibliometric data from our merged academic corpus.

ETO is a project of the Center for Security and Emerging Technology at Georgetown University. Map of Science is maintained by CSET’s data team.
