Steam Turbine Diagnostic System based on a Domain\ud Ontology Implemented using J2EE Technology

摘要

This paper describes the design and the\udimplementation of an aided diagnostic system based on a\uddomain ontology and an expert system. A mono ontology\udobtained from multiple CCOs (Canonical Conceptual\udOntologies) constitutes the knowledge base of the Expert\udSystem. The NCCO (Non Canonical Conceptual Ontology) are\uddefined and used for realising inter-CCO mapping and to\udexpress the relationships between the COO. An expert system\udJESS (Java Expert System Shell) is integrated with the\udontology. Knowledge inference is then possible to solve\udmaintenance cases by given adequate diagnoses to given\udsymptoms. The second aspect of the paper focuses on the\udpossible enhancement and evolution of the developed ontology\udin order to take into account new maintenance cases. The\udcomplete system is developed following a J2EE (Java 2\udEnterprise Edition) architecture.
