Knowledge sharing and cases retrieval are two principal issues in case-based decision support systems.For decision-making in maritime rescue command,this paper adopts Web Ontology Language to represent crisis situations and maritime rescue domain knowledge.Case-based planning process using description logics reasoning for maritime rescue is presented.Representation and reasoning on average situations and the corresponding rescue methods during rescuing grounding or stranding ships are exemplified.The result shows that classifying crisis situations in terms of semantic domain knowledge,with description logics reasoner,could in advance locate the specified case base to be retrieved and help to select reasonable rescue methods,which improve retrieval efficiency and practicability of rescue planning.
