| Domain ontology construction is an important development trend of engineeringproduction, which is an engineering, detailed, standardized and documented process.Compared with the general software, domain ontology emphasis on sharing, reusing,which appears in order to provide a unified semantic integration between differentsystems, so the engineering is more obvious. A variety of domain ontologyconstructions contain degrees of absorption among the software engineering opinions.However, compared with the previous software development, the domain ontologyconstruction more emphasis on evolutionary, and apply the methodology to guide theprocess. Based on the actual situation that high-speed railway knowledge is constitutedby multidisciplinary, this thesis research the definition, expressing, application status ofdomain ontology, and based on formal concept analysis domain ontology engineeringapplications, a domain ontology construction method is put forward based on theCategory table and thesauri high-speed railway, and by this method construct ahigh-speed railway professional ontology and preliminarily consolidated into a unifiedhigh-speed railway domain ontology, formed the basic framework of the high-speedrailway domain ontology, and described that in the language form. The thesis followsthe guiding ideology of engineering, standardization, normalization, detailed, explicitthe basic principles, phasing, and the practical application of the new domain ontologyconstruction, and built the specific process domain ontology at the theoretical andoperational level.Domain ontology results have shown a strong practical application, especially inthe field of high-speed railway ontology construction。 Establish a knowledge of theactual situation in the field of high-speed railway professional institutions and theirpreliminary mergering, on this basis, the initial realization of EMU fuselage built-inhigh-speed rail knowledge and labeling as a development environment. |
