Abstract
This paper applies case-based reasoning method to emergency decision-making research field, and mainly researches case representation and case retrieval method. At first, this paper analyzes character of coal mine emergency rescue work, and describes the coal mine accident case using frame representation. Then this paper adopts the secondary retrieval strategy based on clustering analysis, and designs comprehensive similarity algorithm based on two-layer construct combining structure similarity calculation and attribute similarity calculation. At last, the paper uses retrieval algorithm to show the application of case-based reasoning in emergency decision-making research field taking coal mine gas accident cases as examples.
