AI Technical Summary

Technical Problem

In the field of maritime search and rescue, existing case-based reasoning methods suffer from several problems, including difficulty in accurately matching the heterogeneous features of historical cases from multiple sources, insufficient semantic understanding due to reliance on keyword matching in traditional case retrieval, and a lack of dynamic adaptation mechanisms for case attribute weight allocation. These issues affect search and rescue efficiency and decision-making accuracy.

Method used

A multi-dimensional attribute similarity calculation method is adopted. By preprocessing the case information to be processed and the historical case dataset, including standardization, missing value handling, noise reduction and unified format processing, and combining specialized similarity calculation models of time, space, numerical, enumeration and text attributes, the most similar historical search and rescue experience to the current case is identified.

Benefits of technology

It enables rapid response and precise decision support for maritime emergencies, improves search and rescue efficiency, reduces risks and losses, and provides intelligent and professional technical support.

Abstract

The application discloses a data processing method and device for assisting decision-making of maritime search and rescue, and the method comprises the following steps: acquiring to-be-processed case information and historical case data sets; preprocessing the to-be-processed case information and the historical case data sets to obtain preprocessed case information and preprocessed historical case data sets; and processing the preprocessed case information and the preprocessed historical case data sets to obtain a target case information set. It can be seen that, by using the multi-dimensional attribute similarity calculation method, the most similar historical search and rescue experience to the current case can be accurately identified, the most optimal matching case considering five types of attributes, i.e., time, space, value, enumeration and text, is obtained, the maritime sudden accident can be quickly responded and accurately decided, the search and rescue efficiency is improved, the risk is reduced, the personnel casualty and property loss are reduced, and intelligent and professional technical support is provided for the maritime search and rescue work.
