It may not be uncommon for emerging areas of science, especially those related to rapid technological change in society, to take off quickly, but even by these standards the growth of artificial intelligence (AI) has been impressive. Together with robotics, as these charts show, AI represents an increasingly important part of research volume at various levels.
across the field
The number of AI and robotics papers published in the 82 high-quality science journals in the Nature Index (count) has been increasing year-on-year – resembling an exponential growth curve. A similar increase is also occurring in journals and proceedings not included in the Nature index, as shown by data from a database of measures of research publications.
Five countries — the United States, China, the United Kingdom, Germany and France — accounted for the largest share of AI and robotics in Nature’s index from 2015 to 2021, with the United States leading the pack. China saw the largest percentage change in annual share (1,174%) among the five countries.
The intrusion of AI and robotics
As the field of AI and robotics research continues to grow in its own right, leading institutions such as Harvard University in the United States have increased their stake in this area since 2015. But such leading firms have also seen an expansion in their overall index ratio. A partnership represented by research in AI and robotics. One possible explanation for this is that AI and robotics are expanding into other fields, creating interdisciplinary AI and robotics research.
