基于本体的应急案例相似度算法研究

Research on Arithmetic of Similarity of Emergency Case Baseon Ontology

文章分析了当前案例相似度和语义相似度,提出了针对应急案例语义相似度计算方法。该方法可以定量地分析OWL所描述概念、特性之间的相似度,为应急案例库语义查询中的扩充概念集和查询结果排序打下基础,进一步提高应急决策支持系统的效率。

The current arithmetic of the calculation of similarity of the case and semantic were analyzed, and a new method used to calculate the case of emergency events semantic similarity was put forward. In this way , the similarity of the concept and characteristic decribed by Owl were quanthqcationaUy analyzed;the concept collection of the semantic query of emergency case database could be enlarged and the order of the result of the semantic query of emergency case database could be given, and the efficiency of Emergency Decision Support System was improved.
