Expert system building tools based on dynamically updated knowledge

The paper presents a developed software tool that includes software systems Prolog, JavaScript, Python, as well as database management systems PostgreSQL and MySQL.With the help of the created integrated development environment, experimental versions of specialized expert systems in the field of education and health care were developed. In the field of education, a prototype of an expert system focused on the support of the discipline "development and analysis of requirements for the creation of a software product" was created. This prototype of the expert system should provide an opportunity for students to build various software systems based on the formulated requirements and rules from the knowledge base of the expert system, taking into account the specifics of the relevant subject areas. In the field of health care, a prototype of an expert system focused on supporting the processes of vaccination of patients has been created. The knowledge base of the expert system includes clinical characteristics of patients, as well as a set of rules governing the decision - making processes for vaccines.
