Abstract: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.......
