Emerging Topic Recognition Based on Three-Dimensional Topic Feature Measurement
Recognizing emerging topics is conducive to monitoring the latest trends in development over time,providing valuable information support for researchers'topic selection and research managers'policy decisions.In this study,an emerging topic recognition method based on a three-dimensional topic feature measurement is proposed.First,topic model-ing is conducted using domain semantic knowledge from BERTopic,representing topics by documents as the basic unit.Next,a three-dimensional topic feature index framework based on time,reference,and correlation is constructed to identi-fy emerging topics.The feasibility and effectiveness of the proposed method are discussed through empirical studies,using domain data on text classification as examples.The findings reveal that using documents as the basic unit enhances the ex-ploration of topic features,the three-dimensional topic feature index framework demonstrates good adaptability and expan-sibility,and the proposed method can be generalized application in other domains.At the theoretical level,this work pro-vides a reference method for emerging topic recognition research.At the practical level,it can serve as a reference tool for scientific and technological intelligence analysis and domain development trend analysis.
