针对民航突发事件领域本体非分类关系的语义查询扩展问题，提出一种面向领域本体非分类关系的语义相关度计算方法。该方法在数据属性方面，提出基于属性类型和属性值的语义相关度计算方法；在对象属性方面，针对查询词与本体概念或实例存在多种对象属性问题，提出基于对象属性的语义相关度计算方法，并结合领域本体在民航突发事件案例的语义查询过程给出了该方法的实现效果分析。该方法不仅有效地提高了语义查询的准确率和查全率，也为民航突发事件的应急决策提供了更好的方法支持。%Aiming at the problem of semantic query expansion in regard to non-classification relationships of civil aviation emergency domain ontology (CAEDO),we proposed a semantic relevancy calculation method for the non-classification relationships of domain ontology. In this method,on the aspect of data properties,we proposed a semantic relevancy calculation method which is based on the property type and property value;on the aspect of object properties,aiming at the problem that there are multiple object properties in query words and ontology concept or example,we proposed the object property-based semantic relevancy calculation method.Furthermore,in combination with the semantic query process of domain ontology in civil aviation emergency cases,we gave the analysis of the implementation effect of the method. The method not only effectively improves the precision and the recall of semantic query,it also provides better methods support for emergency decision-making in regard to civil aviation emergencies as well.
