What you should know about this indicator

  • CSET sources the data on the number of articles and citations from the Merged Academic Corpus (MAC), which includes over 260 million academic articles.
  • Articles are marked as AI — related using an automated system.
  • Articles are linked to countries based on the authors’ listed organizations. If at least one author is from an institution in a country, the article counts for that country.
  • If authors are from multiple countries, the article counts once for each country, but only once per country even if there are multiple authors from the same place.
  • For example, an article with authors from both the U.S. and Japan counts once for each.
Number of articles - All
English- and Chinese-language scholarly publications related to the development and application of AI. This includes journal articles, conference papers, repository publications (such as arXiv), books, and theses.

Sources and processing

This data is based on the following sources

The research data in CAT (Country Attributes and Topics) is derived from ETO's Merged Academic Corpus (MAC), which contains detailed information on over 270 million scholarly articles worldwide. CAT uses only AI-related articles from the MAC. Articles are attributed to countries based on the author organizations listed in each article's metadata. An article is attributed to a country if it lists at least one author affiliated with an organization in that country.

The top ten authors for each country are identified based on the number of citations to articles they released while affiliated with institutions in that country. CAT classifies articles into AI subfields using subject assignment scores in the MAC. Articles are assigned to up to three subfields based on their scores.

CAT includes patent data from 1790 Analytics and Dimensions, and it counts AI-related patent families, including patent applications and granted patents. Patents are attributed to the country where they are filed, not necessarily the inventor's nationality. CAT also uses Crunchbase data to identify AI-related companies based on various criteria and includes investment metrics for these companies.

The data in CAT is updated at least once a quarter, with plans for more frequent updates in the future.
