Core Viewpoint - The article emphasizes the importance of technological innovation in driving high-quality development of the marine economy, highlighting the implementation of a three-year action plan by the Beihai Bureau to enhance marine industry data mining capabilities and improve economic monitoring and evaluation [3][4]. Group 1: Technological Innovation and Data Integration - The Beihai Bureau has initiated a three-year action plan focused on technological innovation to support high-quality development in marine industries, resulting in significant achievements in integrating technology, industry, and business innovation [3]. - The project aims to overcome challenges in identifying and classifying marine economic activities by utilizing multi-source heterogeneous data and intelligent algorithms, transitioning from manual assessment to intelligent recognition [4][6]. - A dual-driven model of "external collection + internal governance" has been established to address data fragmentation, enhancing data coverage and real-time capabilities for effective marine economic monitoring [6][10]. Group 2: Data Mining and Quality Control - The marine industry data mining technology has developed a dual-track recognition mechanism with a "marine attribute feature word library" and a "marine national economic industry code library," facilitating efficient identification of marine economic activity units [8][9]. - A total of 1,440 feature words have been extracted to create the marine attribute feature word library, which aids in classifying marine-related industries and improving monitoring efficiency [9]. - Quality control measures have been implemented to ensure data accuracy, maintaining a model error rate below 1%, resulting in a comprehensive directory of over 3 million marine-related units across the country [10]. Group 3: Future Applications and Development - The article outlines plans to leverage digital technology for enhanced marine governance, aiming to improve decision-making capabilities and expand the application of marine economic big data for precise governance [13]. - A "1+4+N" visualization platform is being developed to support various service scenarios, enhancing the ability of marine enterprises to innovate and grow [12]. - Continuous updates to the marine attribute feature word library and the establishment of industry standards for data mining are planned to further improve data quality and usability [12].
