基于本体的设备维护知识表示研究*

为满足设备维护领域知识数字化表示的需求，根据设备维护领域知识的特点，将本体引入到该领域的知识表示中。通过对设备维护资源构成的分析，以设备维护知识中维修经验知识表示为例，分析其概念和属性关联关系，设计了维护案例本体表示方法。采用OWL对维护案例本体进行统一的形式化描述和表示，较好地解决了维修经验知识的共享与重用难题。研究提出的维修经验知识表示方法已在某大机组群监测系统中得到成功应用。

Research on knowledge representation for equipment maintenance based on ontology

To meet the need of knowledge digitized representation in the field of equipment maintenance, according to the characteristics of equipment maintenance field knowledge, this paper introduced the concept of ontology to the knowledge representation of equipment maintenance. By analyzing the structure of equipment maintenance resources, analyzed taking the maintenance experience knowledge as a case and its concepts and property relationships. Designed the ontology representation method of maintenance case. Moreover, adopted the OWL to describe and express the maintenance case ontology formulations, which could solve the sharing and reuse of maintenance knowledge problem well. The knowledge representation method of maintenance experience which was brought forward in this paper had been successfully applied in a group monitoring system of machine union.
