Structure analysis of an explanatory dictionary ontological graph

When working with large connected systems, it is important to present the data in a form that is easy to analyze and process. For that purpose an ontological graph is often used. In this paper, developed tools for constructing and analyzing an ontological graph of the connections in the Russian explanatory dictionary are described. The concepts of specificity of oriented graphs with a large number of loops, vertices and edges are introduced: the vertex hierarchy, word basin, basin shell and basin volume are determined. The statistical properties of ontological graph are investigated. © 2017, Springer International Publishing AG.
