dc.description.abstract© 2021 National Research Nuclear University. All rights reserved.The technology of constructing and visualizing a semantic image of the full text of the document represented by the ontology as a system of three systems is offered: Functional, conceptual and terminological. Objects and connections of the functional system correspond to the names of entities and relations extracted from the text; to objects of the conceptual system-descriptors of the thesauri of subject areas. The problem of the variable representation of entities at the sign level is solved using the rules for the formation of phrases of different lengths. Functional relationships are classified according to the taxonomy of functional relationships and are used to construct aspect projections of ontologies. As the data model of the ontology, a labeled directed graph is used, which includes nodes and arcs of different types, which makes it possible to formalize operations on ontologies. Constructing a display of set elements of ontology into graph elements in such way that elements of different sets of different systems are distinguishable, recognizable and depicted in different ways, allows to implement the principle of correspondence of the graphic image with the semantics of the visualized data. Based on the search tasks typology, metaphors for visualizing the ontology graph are proposed: The "pathfinding" metaphor, characterized by the construction of a directed chain of facts, and the "neighborhood analysis" metaphor, which is characterized by the study of the environment (context) of a fact. The technology and software for the construction and variant visualization of the ontology graph have been developed. Examples of using the proposed models for information retrieval through document texts are given.
