Recent developments in defining ontologies for a domain provide significant potential in model design, able to encapsulate the essence of the diagnostic semantic into concepts and to describe the key relationships between the components of the system being diagnosed. In this paper, a framework based on the knowledge space of the system is developed to guide the fault detection process and better automated...
Historically the railway industry has experienced considerable difficulty in effectively integrating RCM data. Previous work on information integration led to the implementation of a simple three tier architecture, where RCM data was collected from legacy systems, stored in a data repository (or warehouse) and processed using analysis tools. This paper discusses the history of RCM data integration...
This paper describes the application of a new knowledge representation standard to develop domain ontologies. It describes how Web Ontology Language (OWL) enables the capture of the semantics of railway RCM data structures to represent actual and historic asset RCM status information. This was achieved in the context of European railway integration, and in particular the InteGRail project, where the...
