煤矿事故案例本体知识库的构建及推理研究

Research on construction and reasoning of coal mine accident case ontology knowledge base

针对煤矿事故案例知识组织、共享和再利用不足等问题,将本体引入事故案例知识管理中,研究基于本体的事故案例知识库的构建和推理技术。通过分析事故案例知识构建了事故知识表示元组和事故案例元本体。在此基础上,按照知识库模型和构建方法分别构建了事故案例本体库和规则库,从而完成知识库的构建。以瓦斯事故为例实现了基于煤矿事故案例知识库的知识推理应用。研究结果表明,利用所构建的煤矿事故案例知识库能够较好地进行知识组织和知识的自动推理,提高了煤矿事故案例知识的共享和重用。

In order to solve problem of insufficient knowledge organization,sharing and reuse of coal mine accident cases,the ontology was introduced into knowledge management of accident cases,and construction and reasoning technology of the ontology-based accident case knowledge base were studied.Based on analysis of the accident case knowledge,accident knowledge representation model and accident case body model were constructed.According to knowledge base model and construction method,the coal mine accident case ontology and rule base were constructed respectively,thus the knowledge base was constructed.Knowledge reasoning application based on the knowledge base of mine accident case was realized with gas accident as an example.The research results show that using the knowledge base of coal mine accident case can achieve the knowledge organization and knowledge automatic inference,and can greatly improve sharing and reuse of the mine accident case knowledge.
