Abstract:Recently, artificial intelligence is generally considered to be one of the technology to subvert the future, so that the research on artificial intelligence in various scientific and technological institutions has reached an unprecedented heat. In this study, we analyze the application time, geographical distribution and patentee of patent data by patent measurement based on the patent data in the field of artificial intelligence which is included in the Derwent Innovations Index (DII) , and show the distribution of R D strength in the field of artificial intelligence. Besides, we use the information visualization software, CiteSpace, to draw the knowledge map which shows the key technology, technical hotspot and frontier in the field of artificial intelligence. Finally, we analyze the development trend of artificial intelligence.
