Domain ontology can be used to extend the user’s retrieval words and index domanin knowledge. According to the actual situation of high-speed railway domain that is comprised by different professional fields, this paper puts forward a construction methodology of domain ontology based on thesaurus and thematic words of high-speed railway that is built by the experts. This paper details the construction principles for professional field ontology and the merger method for professional field ontologies. Guided by this method, we build various professional field ontology of high-speed railway, and then they are preliminary merged into one unified domain ontology of high-speed railway. Now the domain ontology of high-speed railway is used in semantic retrieval system for high-speed railway knowledge and it improve the recall and precision of system.
