基于Hypergraph的突发事件情景案例表示与检索方法研究
Research on Method of Emergency Scenario Case Representation and Retrieval Based on Hypergraph
摘要
Abstract
[Research purpose]Emergencies have the features of scenario evolution.For emergency cases,we should not only describe the characteristics of a single scenario,but also describe the evolutionary relationship between different scenarios.[Research method]Based on the analysis of the evolution mechanism of emergency scenarios and the characteristics of scenario cases,the hypergraph theory is introduced and applied to the representation of emergency scenario cases,and the hypergraph model of emergency scenario chain is estab-lished.Based on this model,a two-stage retrieval strategy including scenario chain retrieval and scenario feature retrieval and the corre-sponding similarity calculation method are proposed.[Research conclusion]The model can effectively describe the complex evolution characteristics of emergency scenario cases and improve the quality and effect of case retrieval.关键词
