| Abstract: | Research purpose]Based on the multi-dimensional measurement of the characteristics of research frontiers,the frontier topics of science and technology are identified,and the relationship and evolution between science and technology frontier topics are analyzed.Research method]Firstly,topics of papers and patents are mined.Based on the characteristics of frontier topics,four indexes including novelty,growth,influence and interdisciplinary are used to identify science and technology frontier topics.Secondly,the topic pairs with evolutionary relationship are identified by the methods of topic similarity calculation and topic filtering,and the evolution process of research frontier topics are analyzed by using the visualization tool.Research conclusion]Taking solid oxide fuel cell as an example,four science frontier topics including the solid oxide fuel cell stack research and four technology frontier topics including composite electrode materials research are identified,and in this field science research and technology research promote each other,presenting a double spiral development. |
