SOME FEATURES OF THE CONSTRUCTION
OF ONTOLOGIECAL DOMAIN MODELS

Introduction. The paper discusses the features of building ontological models of subject areas. A comparative analysis of the most well-known logical theories of the formalization of these models and the corresponding tools for the construction and use of ontologies is performed. An example of using the developed information technology based on the standards and recommendations of the W3C consortium is given.

Purpose.Consideration of the most well-known tools for the formal description of domain ontologies, their comparative analysis and the choice of a formal language and ontoeditor for practical use.

Methods. The methods and models used in the work are based on the information technologies of the Semantic Web, focused on the development and use of domain ontologies. Ontologies are the basic components of these technologies for both research and the creation of large projects, including commercial ones. The use of methods of system-ontological analysis revealed the advantages and disadvantages of various formal and informal descriptions of ontologies. Of the informal models, the CRF model was considered, and the formal models, the Frame model and the OWL model. It also compares the characteristics of these models with a set of descriptive logics.

Results. Information technology has been developed to enable the construction of ontologies of subject areas, including the outline design stage, the input information input into the computer, the formal description of the project, and the practical use of ontologies.

Conclusion. The formalization of the definition of the domain ontology is briefly considered; a comparative analysis of known models of ontologies, such as CRF, Frame and OWL, is performed. Their advantages and disadvantages are noted, and it was concluded that when developing large ontologies, all three indicated models should be used. At the initial stage – a CRF-model for automating the construction of the structure of domain concepts and their semantic consistency.At the stage of input and formalization – a model of Protйgй-frames.And at the stage of ontology use – the OWL-model with the mechanisms of inquiries and reasoning. At the same time, ontology sharing implies its placement on the Semantic Web. The article gives an example of building and using owl-ontology for a certain construction company.
