The development of network and information technology has brought changes to the information environment. The sources of information are becoming more diverse, and intelligence acquisition will be more complicated. The intelligence reflected by different dimensions of scientific and technologi-cal ( S&T) data will have their own focuses. It has become inevitable to carry out the multi-dimen-sional research of S&T frontier, which is also a current research hotspot. This paper uses quantita-tive and qualitative research methods to conduct research and analysis of S&T frontier detection from three dimensions including S&T research projects, S&T papers and patents, and proposes related re-search methods and development tools. This work analyzes the S&T frontiers in the field of artificial intelligence and draws conclusions based on the analysis results of real and effective S&T data in three dimensions.
