基于本体的应急救援知识库构建及其应用

针对专家系统在应急救援领域应用中存在的知识表示及推理等问题,采用基于本体的知识表示方法与基于Jena的规则推理引擎,参考简单知识工程方法论与Jena规则语法建立一个高速公路应急救援本体与推理规则,实现本体知识库的推理。将该知识库应用于高速公路应急救援系统中,结果表明其具备解决实际问题的能力;有利于领域知识的共享与重用;促进了专家系统在高速公路应急救援领域的发展。

Construction and Application of Ontology-based Knowledge Base for Emergency Rescue

Ontology-based knowledge representation approach and Jena-based reasoning engine are proposed for solving the problems about knowledge representation and reasoning exiting in expert system for emergency rescue.Emergency rescue ontology and some inference rules are built by Simple Knowledge-Engineering Methodology and Jena Rule Syntax,and the reasoning for ontology knowledge base is realized.The proposed ontology is applied in an expressway emergency rescue system,the result shows that this knowledge base is of the ability to solve the practical problem;it is helpful for the sharing and reuse of expressway emergency rescue domain knowledge;and it stimulates the development of expert system in the domain of expressway emergency rescue.
