Topic identification and hotspot analysis in field of water conservancy informatization based on patent data
摘要
Abstract
Patents in water conservancy informatization represent the application and outcomes of information technology in the water sector,playing a crucial role in water engineering management and informatization development.Using patent data as the research object,this study proposed a patent-based analysis framework to statistically analyze key factors such as application trends,geographical distribution,and technological fields.Additionally,the LDA(Latent Dirichlet Allocation)topic model was employed to identify themes and hotspots in water conservancy informatization patents,revealing the technical structure and development trajectory of this field in China.The study provided vital insights to standardize academic construction in water conservancy informatization and promote orderly development.The LDA model categorized the patents into six application domains:hydraulic equipment,engineering construction,data monitoring,water conservancy warning,information management,and scheduling analysis.The findings reveal that patents in the information management category are numerous and steadily increasing,indicating promising technological prospects,whereas the water conservancy warning category shows lower activity,highlighting it as a weak area requiring greater investment in technical planning within this domain.关键词
