A CBR approach to predicting demand for waterway transportation emergency resources was worked out in this paper. Firstly,through analyzing the scope of waterway transportation emergency events and history cases of maritime accidents in the main channel of Yangzte river,characteristic attributes the cases were extracted,which can both ensure integrity of cases and improve the retrieval efficiency,and frame-based representation of cases was defined. Characteristics of emergency resources demand in waterway transportation emergency were also discussed. And then,a method of calculating the similarity with different attribute values was introduced. Weight values of attributes were determined. The K-nearest neighbor method was adopted to calculate the overall similarity,so as to solve the resource prediction problem. Finally, example analysis demonstrates that resource demand can be predicted by means of this method.
