Application of the ontological approach when designing a medical mobile Аpp

This paper examines the design of a mHealth-class mobile application that allows to follow the recommendations for vaccine prevention and promotes the prevention of infectious diseases. However, despite the openness and availability of information in this area, there is a lack of objective and reliably verified information. The article proposes a project for a medical mobile application for recording vaccinations. Which will take into account the data of the national schedule of preventive vaccinations and a number of indicators, individual for each child (age, well-being of the child, allergy susceptibility, temperature, time of previous vaccination, etc.). Based on which the vaccination schedule should be formed «for a particular child» and, if new data are entered, corrected and/or shifted. As a model of knowledge representation, we choose the ontological approach, which allows presenting a coherent system of concepts of the subject area under study. The main tasks of the medical BR are as follows: informational support for parents (maintaining a current national schedule of preventive childhood vaccinations, information about existing vaccines and their manufacturers, possible allergic reactions, etc.); creating a scene reflecting the individual characteristics of the child; maintaining a hierarchy of classes of concepts, individual instances and properties of these concepts. In the course of the study, an ontology developed by using the Protégé ontology editor, a comparative analysis of available analogues performed on the market, and a detailed list of functional requirements that a vaccination accounting application must meet was developed.
