Structural Transformations in meta-Associative Graphs and Ontologies Built on their Basis

This article is devoted to the application of ontologies for the creation of structured and unified data models that facilitate the effective management and adaptation of cyber-physical systems. An object-oriented approach to ontological engineering is considered and its effectiveness for managing cyber-physical systems and improving their flexibility is substantiated. As a basis for ontological engineering, meta-associative graphs are proposed as a tool for representing systemic relationships, with the ability to perform structural transformations necessary for the adaptation and modification of ontological structures in dynamically changing conditions. The importance of flexibility and dynamics of meta-associative graphs in the context of constantly evolving cyber-physical systems is emphasized and the importance of applying an integrated approach to ontological engineering to achieve a high degree of adaptability and responsiveness of systems is demonstrated. An approach to the development of software and tool environments that ensure the implementation of ontological engineering capabilities based on meta-associative graphs is described. An example of the environment used for the Electronic University project is considered, as well as an example of the application of the attributive expansion operation within this environment.
