[Purpose/significance] The research on the method of identifying research fronts has been the focus of scholars, this paper aims to analyze the advantages and disadvantages of existing research fronts identifying methods, establish a relatively reasonable research fronts identifying method model, and quickly and efficiently aid R&D managers and policy makers to identify research frontiers. [Method/process] Based on summarizing the related concepts about research fronts and the characteristic of research fronts, it defines the connotation of research front and proposes two indexes of research fronts ages and authors number with the concern for identifying research fronts. Then it builds a feasible method about identifying research fronts based on keywords co-occurrence, and applies in LED. [Result/conclusion] The result indicates that the method not only can effectively identify research fronts but also track the generation, growth, decline, and disappearance of research fronts.
Key words： keywords co-occurrence; research front; research area analysis
