My Thesis is about developing an expert systems as an intelligent system or Artificial Intelligence(AI) system. I used CLIPs and java codes for my expert system that allows a patient or user to book an appointment with a specific doctor based on the patient's or user's symptoms. I used Java for my source code to create an android mobile application that helps the user book the appointment. In this android application, the expert system will select the type of doctor using the user's symptoms preferences. All the database collected in the android application from the users, I use firebase database to manage and protect the database. The main goal of the thesis is to use the knowledge of Expert systems or AI to reduce over crowdedness and reduces the spread of the COVID-19 virus, and also make medical attention much easier.
