Abstract

This paper describes the design and the implementation of an aided diagnostic system based on a domain ontology and an expert system. A mono ontology obtained from multiple CCOs (Canonical Conceptual Ontologies) constitutes the knowledge base of the Expert System. The NCCO (Non Canonical Conceptual Ontology) are defined and used for realising inter-CCO mapping and to express the relationships between the COO. An expert system JESS (Java Expert System Shell) is integrated with the ontology. Knowledge inference is then possible to solve maintenance cases by given adequate diagnoses to given symptoms. The second aspect of the paper focuses on the possible enhancement and evolution of the developed ontology in order to take into account new maintenance cases. The complete system is developed following a J2EE (Java 2 Enterprise Edition) architecture.

基于领域本体的汽轮机诊断系统采用J2EE技术实现
本文介绍了一个基于领域本体和专家系统的辅助诊断系统的设计与实现。由多个规范概念本体(CCOs)组成的单一本体构成了专家系统的知识库。定义了非规范概念本体(Non - Canonical Conceptual Ontology, NCCO),用于实现cco之间的映射和表达COO之间的关系。将专家系统JESS (Java expert system Shell)与本体集成。然后,知识推理可以通过对给定症状给出适当的诊断来解决维护案例。本文的第二个方面侧重于开发的本体可能的增强和演变,以便考虑新的维护案例。整个系统是按照J2EE (Java 2 Enterprise Edition)架构开发的。
