Ontological model of information flows in a digital educational environment

Digitalization of education necessitates a formalized representation and systematic organization of information flows that ensure effective interaction of participants in the educational process in the digital educational environment (DEE). The aim of the study is to model information flows based on an ontological representation of the interaction of a decision maker (DM) and feedback. An ontological model has been developed that reflects key classes, instances with the identification of relationships between them and the semantics of information flows circulating between the DEE components. The article presents a decomposition of an instance of the "adaptive feedback algorithm" class of the ontological model of information flows. Digital tools operate in a single circuit of the educational environment, implementing a continuous cycle of assessment, analysis, feedback and correction. An instance of the "unified test question bank" class of the ontological model, including artificial intelligence technologies for the implementation of automated verification of free-form answers in the conditions of streaming learning, allows for variable and level assessment. Feedback implementation tools include LMS, social networks and a virtual information and communication assistant. The relationship of the tools supplemented in the DEE is shown in the ontological model when describing the information flows of the "DM – feedback" connection. The application of the model considered in the article will allow structuring and unifying the description of educational processes with the automation of the digital footprint analysis. The conclusion provides findings with the decomposition of the ontological model using the example of the knowledge assessment process in the context of digitalization and multithreading with the identification of relations in the form of prerequisites of instances of classes of the ontological model.
