Abstract:

Concerning of the importance of equipment fault knowledge base construction and the insufficiency of existing fault knowledge representative methods, ontology is adopted to construct equipment fault knowledge base. After the analysis of the relationship between ontology and knowledge base and the characteristics of equipment fault knowledge, the structure of equipment fault knowledge base is proposed. Then a construction method of knowledge base is put forward and its detailed process and the key technology of ruledbased reasoning are elaborated. All the work achieves the construction of ontology based equipment fault knowledge base. This research provides a method and a technical route for the construction of other domain knowledge base.
