Foreign submarine sonar research topic analysis based on LDA model
This study utilized the Science Citation Index to retrieve 1 108 international publications closely related to the topic of"submarine sonar"as its data source.By employing Latent Dirichlet Allocation(LDA)topic modeling tech-niques,six core themes were precisely identified:sonar technology and applications,sonar and robotics,sonar detection sys-tems and applications,underwater communication and navigation,sonar technology in anti-submarine warfare,and sonar and artificial intelligence.Based on these themes,we conducted a systematic classification,summarization,and in-depth analysis of the original data.This research aims to provide researchers in related fields with a means to quickly grasp the develop-mental trajectory of the field by thoroughly analyzing the current research focus and trends in international literature.This ef-fort not only helps Chinese researchers accurately pinpoint future research directions but also actively promotes the advance-ment of China's submarine sonar technology and the development of its maritime power strategy.
