The Use of Certainty Factor (CF) in the Design of an Expert System to Diagnose Atherosclerosis

Introduction

Atherosclerosis, a disease characterized by a buildup of plaque on the arterial wall, is a serious health problem that can cause stroke and heart disease. Early detection is the key to preventing and handling this disease. Expert systems, computer programs that mimic the process of thinking of human experts, offer innovative solutions to help the diagnosis of Atherosclerosis. This study focuses on the development of an expert system based on Certainty Factor (CF) to diagnose Atherosclerosis. This system uses production rules to represent expert knowledge about this disease, connecting the symptoms experienced by patients with the possibility of atherosclerosis. The CF is used to calculate the level of trust in diagnosis based on the symptoms entered by the user.

The Importance of Certainty Factor (CF) in Expert Systems

Certainty Factor (CF) was chosen because of its ability to deal with uncertainty in decision making. In the context of the diagnosis of the disease, information obtained from patients is often incomplete or uncertain. CF allows the system to consider the level of trust of each symptom and calculate the overall level of trust in the diagnosis. This is particularly important in the diagnosis of atherosclerosis, where symptoms can be subtle and easily misinterpreted.

The Role of Expert Systems in Atherosclerosis Diagnosis

Expert systems can help identify atherosclerosis risks in the early stages, when symptoms are still mild or not clearly visible. This is a significant advantage over traditional diagnostic methods, which often rely on more overt symptoms. Additionally, expert systems can be accessed easily, thus allowing more people to get an initial diagnosis. This is particularly important in rural or underserved areas, where access to medical care may be limited. Furthermore, expert systems are available 24 hours a day, 7 days a week, so patients can get a diagnosis at any time.

The Design of the Expert System

The expert system designed in this study uses the forward chaining method, which moves from the initial facts (symptoms) to conclusions (diagnosis). This method is particularly well-suited for the diagnosis of atherosclerosis, where symptoms can be complex and multifaceted. The system uses production rules to represent expert knowledge about this disease, connecting the symptoms experienced by patients with the possibility of atherosclerosis. The CF is used to calculate the level of trust in diagnosis based on the symptoms entered by the user.

System Implementation

The expert system was implemented using Delphi 7.0 programming language. This language was chosen because of its ease of use and flexibility, making it an ideal choice for developing expert systems. The system was designed to be user-friendly, with a simple and intuitive interface that allows patients to enter their symptoms and receive a diagnosis.

The Benefits of the Expert System

The expert system offers several benefits over traditional diagnostic methods. Firstly, it can help identify atherosclerosis risks in the early stages, when symptoms are still mild or not clearly visible. This is a significant advantage over traditional diagnostic methods, which often rely on more overt symptoms. Secondly, the system can be accessed easily, thus allowing more people to get an initial diagnosis. This is particularly important in rural or underserved areas, where access to medical care may be limited. Finally, the system is available 24 hours a day, 7 days a week, so patients can get a diagnosis at any time.

Conclusion

Expert System Based Certainty Factor For diagnosis of atherosclerosis offers innovative solutions to increase early detection of disease. The use of the forward chaining method and Certainty Factor allows the system to produce accurate and reliable diagnoses based on symptoms entered by the user. This system is expected to help increase awareness and access to the diagnosis of atherosclerosis, so as to help reduce the risk of stroke and heart disease.

Future Directions

Future research should focus on refining the expert system to improve its accuracy and reliability. This can be achieved by incorporating more data and knowledge about atherosclerosis, as well as by testing the system with a larger and more diverse population. Additionally, the system should be made more user-friendly, with a simpler and more intuitive interface that allows patients to easily enter their symptoms and receive a diagnosis.
