基于BERTopic的新兴技术主题识别研究
Research on Emerging Technology Topic Identification Based on BERTopic
摘要
Abstract
[Purpose/significance]Identifying and foreseeing emerging technologies,bring technological first-mover ad-vantages to enterprises and governments,and grasp technological development trends in a timely manner.[Method/process]This study uses BERTopic's topic modeling method to obtain domain topic distribution,and merges paper and patent topics based on the cosine similarity of topic vectors to identify emerging topics.[Result/conclusion]Using the BERTopic topic modeling method combined with index evaluation can effectively identify emerging topics and emerg-ing terms.Taking the field of new energy vehicles as an example to carry out empirical research,using two methods:di-vided verification period and data verification method,12 of the 16 identified topics passed the verification,which ver-ified the effectiveness of this research method.关键词
