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.

The Map of Science includes over 130 million scholarly publications from around the world, algorithmically organized into over 116 thousand research clusters. These clusters are groups of papers that cite each other a lot - typically because they share other things in common, such as subject matter, language of publication, or other important characteristics. By filtering clusters according to growth over time, key topics, countries, and other characteristics, you can quickly pinpoint scientific trends and communities.
