Construction and Application of Marine Rescue and Salvage Knowledge Graph
Aiming at the problem that the knowledge system in the field of Marine Rescue and Salvage(MRS) is scattered and the massive case data cannot be effectively mined and utilized,through the detailed analysis on rescue and salvage acci-dent cases and standard specification documents,five types of accident objects,nineteen scenarios,and key rescue and sal-vage capabilities required for each scenario are obtained. Based on the relationship between these scenarios and capacity re-quirements,the top-down and bottom-up combination is used to construct the internal entity and attribute graph of MRS. The data is structured and mapped to the design graph,and the construction and application of the knowledge graph is real-ized by combining the decision recommendation rules. The research results show that the MRS knowledge graph can effec-tively carry out the retrieval and query of the rescue and salvage knowledge,the visualization of knowledge display and infor-mation statistics,and the recommendation of auxiliary decision-making schemes,which provides a more systematic and in-telligent support tool for operations in related fields.
