Ontology for design, application and support of scientific and engineering data portals

In the article the description of the development of an ontological model for semantic research portals is given. They are a new class of semantic portals focused on working with scientific and educational knowledge. Such portals allow supporting educational processes and processes of obtaining scientific knowledge in applied domains. The domain has been described by using problem-oriented models. Developing ontology includes: defining the end-user and application scenarios of ontology; the definition of requirements to the model; determination of the possibility of reusing existing ontologies; verification of the ontological model on the basis of competence issues. The existing models: VIVO, TEACH, FOAF, BIBO were utilized in the development of the described ontology model. The developed ontology model consists of several modules: module description of the user; a module for description of data sources; a module of the training resource; module for description of search results. A novelty of the approach lies is the way that domain knowledge is derived from open sources, taking into account the interests of the users of the portal and stored in the ontological model. The possibility of new portals is shown by the example of the portal developed for the ITMO University.
