On the structure of the Common Digital Space of Scientific knowledge ontology

Abstract

The work is a development of the research conducted by the authors in the field of creating a Common Digital Space of Scientific Knowledge (CDSSK). The CDSSK is a digital information structure aggregating heterogeneous polythematic information related to scientific knowledge and including a set of subspaces related to various thematic scientific areas. The sources of the CDSSK content are existing information systems, such as the Great Russian Encyclopedia, the Unified Catalog of Geographical Names, the National Electronic Library, etc. A distinctive features of the CDSSK are (a) data support in a structure that complies with the rules of the semantic WEB, and (b) the ability to process a wide range of polythematic queries and provide the ability to navigate through heterogeneous resources using semantic links between them. The real design of the CDSSK should begin with the formation of the ontology of space as a whole and its individual subspaces. In this paper, a hierarchical structuring of the CDSSK ontology is proposed. Such elements as "subspace", "class of objects", "object", "attributes of an object", three types of relations of objects and attributes (universal, quasi-universal and specific) are distinguished and defined. the concepts "reference books" and "dictionaries" of the CDSSK are introduced. Reference books contain information about attributes and their relationships and are used in the processes of content formation and implementation of search and navigation logic; dictionaries contain specific values of attributes and relationships. The formalization of these elements representations is proposed, which makes it quite simple to add, as necessary, new attributes and relationships between objects.
