Objective To investigate the status quo and hot spots of studies on international artificial intelligence in the new century. Methods The hot spots of studies on international artificial intelligence were revealed by literature statistical analysis and key words co-occurrence analysis using the TDA software. Results The number of literatures on international artificial intelligence tended to increase, ranked first in USA and 6th in China. The major research fields of artificial intelligence were computer science, engineering, automation and control system, and the main hot spots of studies on artificial intelligence were genetic algorithms, neural networks and machine learning. Con- clusion Studies on international artificial intelligence in the new century involve a number of subjects. The hot spots of studies on international artificial intelligence are focused on the access to knowledge, expression of knowledge and solutions for problems, with the neural networks, genetic algorithms and machine learning most concemed.
