基于本体的列车运行调整知识库构建研究

The Construction of Train Operation Adjustment Based on Ontology

考虑到列车运行调整知识组织、共享和再利用不足等问题,将本体引入列车运行调整领域知识中,通过分析列车运行调整过程明确知识范围,提取其中主要要素构建知识表示元组。在此基础上,利用Protégé软件构建了基于本体的列车运行调整知识库,主要由列车运行调整知识本体、规则库和推理机三部分组成,并结合具体的实例展示了基于列车运行调整本体知识库的知识推理应用。结果表明利用本文所构建的列车运行调整本体知识库能够较好地进行列车运行调整领域知识的组织和推理,提升列车运行调整的实时效率和调度决策的合理性,为列车运行调整自动化的实现提供了新的方法和思路。

Considering the inadequate utilization of train operation adjustment knowledge,this paper firstly introduces the ontology into the domain knowledge of train operation adjustment,The scope of knowledge is identified by analyzing the process of train operation adjustment,then the main elements are extracted to construct a knowledge representation tuple.Based on the above,the protégésoftware is used to construct a train adjustment ontology knowledge base which is mainly composed of three parts:train operation adjustment knowledge ontology,rule base and inference engine.In addition,the knowledge reasoning application is demonstrated based on the train operation adjustment ontology knowledge base combined with specific examples.The train operation adjustment ontology knowledge base in this paper can better organize and reason about the train operation adjustment domain knowledge,improve the real-time efficiency of train operation adjustment and the rationality of dispatching decisions,and it provides new methods and ideas for the realization of train operation adjustment automation at the same time.
