A spatial awareness case-based reasoning approach for typhoon disaster management

Knowledge learning from similar historical cases is critical for emergency decision making against typhoons. Case-based reasoning technology is increasingly adopted to find the appropriate disaster cases matched to current typhoons. However, the matching results is not satisfying. The reasons are that the typhoon disaster case repository is lacking in a unified and comprehensive specification and that the important spatial attributes of cases are often overlooked or simply described. Based on the investigation of practical typhoon cases, a novel approach is proposed to define the case with explicit and comprehensive spatial multi-elements. With the spatial analysis function and the data management capabilities of GIS, the spatial awareness CBR method is discussed. Lastly, a framework of applying the prosed method to Guangdong Emergency Platform System for testifying is introduced.
