Detecting of Research Front Topic in Artificial Intelligence Based on SciVal.

The era of intelligence marked by artificial intelligence is coming. Accurate judgment of research front in AI can influence the policy orientation of AI technology. Based on Scopus database, artificial intelligence related papers between January 1, 2012 and July 1, 2018 were retrieved. SciVal analysis tool was used to identify research fronts in artificial intelligence. The results showed that four research fronts are determined according to the value of topic prominence. Based on the distribution of high-frequency keywords in the four research frontiers, and combined with the relevant literature of artificial intelligence research, the key research contents contained in each front topic were analyzed. United States still rank first in terms of both applied and basic research.
