The article analyzes the architecture of electronic educational systems (EES) and the possibility of decomposition into subsystems according to the implementation of the functionality they perform. The types of connections and the possibility of interaction of subsystems are considered. The dynamic features of the EES architecture and the influence of factors that may arise during its operation are highlighted.
The types of agents and the interaction between them were studied to ensure the adaptive components of the work of knowledge assessment systems. The types of agents and their interaction with EES are considered in detail, examples are given. The working principles and interaction schemes of independent agents and agents united in groups have been studied, their interaction schemes are given. The effectiveness of combining agents into groups and the expediency of such an approach are highlighted.
The scheme of the work of an independent agent with an adaptive component and the influence of its work on the result and input data of other agents are shown. Weighting factors are added to each of the agents, which are responsible for adjusting the work of each of the input factors, which in turn form the overall result. The weighting factors are static elements that are based on expert data and are defined between 0 and 1.
Based on the agent approach, an adaptive quasi-static mathematical model has been developed, on which the adaptive component of information technologies for the analysis of the context of knowledge assessment systems will be based. The developed model is takes into account the dynamism of the architecture of knowledge assessment systems and includes management of the adaptive functions.
The developed agent model reflects an iterative process in time, the result of which consists of the sum of the results of the work of groups of agents over the entire range of knowledge evaluation. The model includes the possibility of emergency shutdown of the system in case of a corresponding command of the agent.
The main advantages of the designed model are universality, provision of an adaptive component, i.e., considering the dynamics of changes in parameters over time and the possibility of their rating. Such a model autonomizes the components of information technologies of context analysis in knowledge assessment systems, providing opportunities to change its own functionality and independent functioning.
