Identification of Emerging Technologies Based on Overlapping Community
Identifying emerging technology themes based on patent data is beneficial for accurately grasping future technology trends.This article creates a patent citation network to reflect the degree of technological clustering,develops an initial community through the citation network clustering based on the Louvain community discovery algorithm,and designs an overlapping community discovery algorithm of core-edge label propagation to obtain the overlapping patent dataset.Taking the overlapping patent dataset as a candidate emerging technology,it establishes an emerging technology identification index system to judge the patents of emerging technologies in the candidate set,and performs topic mining.This study suggests that:combining Louvain algorithm with core-edge label propagation algorithm can obtain high-quality overlapping communities;based on overlapping communities,multi-dimensional metrics,and LDA model,emerging technology topics can be accessed more comprehensively and accurately.
