摘要：The problem of correlating and comparing the levels of the European and national qualifications framework and the potential of Semantic Web technologies for solving this problem were explored. We substantiated the need for creating models and methods, aimed at providing transparency of the European and national qualifications frameworks and the development of tools for implementing these methods.Authors proposed a reference model of the qualifications framework that formalizes knowledge of basic information objects relating to learning outcomes and their representation in the qualifications frameworks. The specific feature of this model implies using atomic competencies: semantics of information objects of different classes is formalized through a set of such atomic competences that are associated with different properties of these objects. This should provide for the automatic juxtaposing of these information objects on the level of knowledge. The methods of calculating measures of semantic proximity between information objects of different classes of ontological models, which corresponds to different problems, are proposed in the work. This allows identifying a similarity between learning outcomes, which are described with the use of descriptors of different qualification frameworks.Information regarding atomic competences is obtained from the national and European standards, qualifications frameworks, speciality descriptions, etc. They may be automatically supplemented via analysis of relevant information of Web-resources that contain semantic markup.The work considers in detail the mechanism of integration of the reference information model of competences with technological environment Semantic MediaWiki: ontology concepts and relationships are used for semantic markup of Wiki-pages as categories and semantic properties. This allows running a variety of semantic queries to the content of pages, relating to learning outcomes. Examples of such queries are given and their expressive power is analyzed.An example of using the ontological model of competences for improving semantic Web-search for the information for the purpose of supplementing and updating Wiki-pages was studied. The ontology potential in specification of information needs and the increased intersection of the obtained results is demonstrated with the example of the semantic search engine MAìPS.
