Common Digital Space of Scientific Knowledge Ontology Structurization

The paper proposes the unified ontology structure model of the Common Digital Space of Scientific Knowledge (CDSSK). The CDSSK is a digital information structure aggregating heterogeneous information related to various aspects of scientific knowledge and acting as an integrator of national information systems with subject-specific scientific information systems, digital libraries, registers, etc. CDSSK provides data support in a structure that complies with the semantic Web rules and can be considered as an information basis for solving artificial intelligence problems. The CDSSK distinctive feature is the polythematic and heterogeneity of content elements with the ability to navigate through it’s space resources using semantic relations between them. Within the proposed model framework, a hierarchical structuring of the CDSSK ontology is carried out. Such elements as ‘‘subspace,’’ ‘‘class of objects,’’ ‘‘object,’’ ‘‘attributes of an object,’’ three types of pairwise relations of objects and attributes (universal, quasi-universal and specific) are distinguished and defined. Each structure of elements type is determined by a ‘‘reference book’’ of a unified type; specific values of attributes and relationships are contained in dictionaries of a unified structure. A class of ‘‘Formats’’ objects describing the rules for the formation of attributes and the relationships values is allocated. The proposed formalization of the CDSSK elements representations allows to simply add new types of objects, their pairwise attribute relationships, to the space, as needed.
