| Abstract: | Purpose/Significance]In order to improve the comprehensiveness and accuracy of the identification of emerging technology topics,it is necessary to enrich data source information.This research proposes a composite emerging technology topic identification method on the basis of patent,paper and public opinion information.It is expected to provide a reference for the research on the topic identification methods of emerging technologies at the micro level.Method/Process]Firstly,using the LDA model to extract candidate emerging technology topics.Then,choosing the final emerging technology topics by theme screening indicators.Finally,the emerging technology topic is predicted by using CRITIC method.Result/Conclusion]In the experiment,intelligent connected vehicle is taken as an example.The experiment successfully identifies one emerging technology:multi-sensor fusion information technology.The experimental results are consistent with the industry analysis,indicating that the multi-indicator emerging technology topic identification method from the multi-source information perspective can effectively target multiple sources. |
