Common digital space of scientific knowledge as an integrator of polythematic information resources

The goals, objectives, and structure of the ontology of the Common Digital Space of Scientific Knowledge (CDSSK) are considered. The CDSSK is an integrated information structure that combines state scientific information systems presented on the Internet (the Great Russian Encyclopedia, the National Electronic Library, the State Catalog of Geographical Names, etc.) with industry information systems, databases, and electronic libraries (MathNet, Socionet, Scientific Heritage of Russia, etc.). CDSSK can be considered as an information basis for solving artificial intelligence problems. The article presents the unified structure of the CDSSK ontology developed at the Joint Supercomputer Center of the Russian Academy of Sciences and its modeling on an example of ten subject classes and eight auxiliary classes of objects of the CDSSK universal subspace.
