Adaptive Software System Based on Ontological Approach for People With Cognitive Impairments

Abstract

The paper presents a method of creating an adaptive software system to help people with cognitive impairments, based on the use of an ontological model of the subject area. The specifics of creating software tools to help people with cognitive impairments are analysed. The features of using the ontological approach for the formation of adaptive functionality and graphical interface are revealed and their advantages over traditional methods are analysed. It was found that when using this method, there is no need to recompile and fully deploy the software system in the event of a change in business logic. An ontological model of the subject area has been designed, which will make it possible to customize the system for the needs of a particular user. The architecture of a software system based on an ontological model of the subject area is proposed, which takes into account the possibility of personalizing the components of the system and the user interface without the need to re-deploy the system. The process of adaptation of a mobile application based on data about health disorders of the user using an ontological model of the subject area is disclosed. The result of the research is the development of a software system that implements the proposed adaptation process and allows to modify a mobile application for the needs of a specific user, using an ontological model of the subject area.
