Research on high-speed railway ontology integration method based on semantic relationships

The high-speed railway area is composed of several different domains, such as operation management, signal and communication, traction power supply, infrastructure, EMU, passenger service and so on, and the normal integration approach is not applicable. In order to integrate multiple majors domain ontology, this article, takes the high-speed railway area as researching and applying object, analyzes composition of technical systems and withdraws three integrated relations-material, energy and information. On that basis, we establish relationships between the various sub-areas. Finally, the article proposed a method, which based on the ontology view integration method, to construct ontology integration view in high-speed railway, and integrated the EMU ontology and traction power supply ontology. The ontology integration method on high-speed railway area in this article can be used in other similar technical areas which consist of several major domains; it has reference significance to the research towards the integration of information resources and information services composition.
