Which countries and universities are leading on AI research?

China has been producing almost twice as many papers on artificial intelligence as the next highest-placed country in terms of publication volume for the field, a data analysis for Times Higher Education has shown.

Data from Elsevier’s Scopus database provided to THE illustrate China’s huge drive on research in the area, with researchers in the nation notching up just over 41,000 publications from 2011 to 2015.

However, although China scored high in terms of volume, it was only 34th in terms of field-weighted citation impact (which allows for differences in citations according to subject and year), suggesting that most of the papers were not of the same quality as those coming from the US (fourth for citation impact), for instance.

Leading the world on this measure was Switzerland, with a citation impact score of 2.71, followed by Singapore (2.24) and Hong Kong (2.00), although all three of these produced fewer than 2,500 publications on AI over the time frame.

Looking at individual institutions that published more than 500 times on AI shows that only one in China – the Institute of Automation, Chinese Academy of Sciences – had a citation impact above the world average of 1.

The list ranked by citation impact is topped by the Massachusetts Institute of Technology with a score of 3.57. This is way ahead of the rest of the chasing pack, including Carnegie Mellon University and Nanyang Technological University, Singapore.
