[目的/意义]识别并预见新兴技术,为企业和政府带来技术先发优势,及时把握技术发展趋势。[方法/过程]本研究采用BERTopic的主题建模方法获取领域主题分布,依据主题向量的余弦相似度合并论文和专利主题,实现新兴主题的识别。[结果/结论]运用BERTopic主题建模方法结合指标评价,能够实现新兴主题与新兴术语的有效识别。以新能源汽车领域为例开展实证研究,使用划分验证期和资料验证法 2 种方式进行验证,在识别出的 16 项主题中有 12 项通过验证,证实了本研究方法的有效性。
Research on Emerging Technology Topic Identification Based on BERTopic
[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.
