领域前沿识别方法综述

Purpose/significance] This paper summarized the advantages and disadvantages of various recognition methods of frontier researches by comparing and analyzing these methods, and suggested improvements for future researches.[Method/process] Firstly, it reviewed the literatures related to research frontiers at home and abroad, and identified relevant concepts of the research frontier. Then, the paper analyzed the main exsited research methods for the identification of research frontiers. Comparing with the traditional identification methods, this paper emphasized the summary of recognition methods of transformative research frontiers. Finally, this study summarized the main problems existed in the frontier identification methods, and put forward suggestions for improving the research frontier identification methods.[Result/conclusion] In terms of conceptual meanings, this paper distinguished research hotspots, emerging researches and research frontiers in the dimensions of time and innovation. According to the different levels of innovation, research frontiers can be divided into conventional research frontiers and transformative research frontiers. In terms of identification methods, different methods have their own applicable scenes. In the future, it is necessary to further dig out the measurement features of the "research frontier", especially the semantic associations among topics and the fusion of multiple relations should be focused on, as well as the feature mining of the early signs of "transformation research frontier", and then constructing corresponding recognition and prediction methods.
