One of the advantages in using CBR in this project is that the expert system will have a substantial expert knowledge in the knowledge based. Moreover, it tries to mimic one of the method for doctors to diagnose their patients as reasoning with cases is important in medical practice of all kinds.
The doctor is trained to use facts, knowledge and hands-on experiences.
They were trained by studying real life cases so that later they will be able to recognize disorders or common combinations of disorders, how the disorders were treated and later make inferences (drawing a conclusion).
In CBR research, there are many approaches for modeling the prior and making inferences.
The most common approaches in CBR are statistically-oriented, model-based, planning/design-oriented, exemplar-based, and adversarial or precedent-based.
In this work, we used statistical-oriented approach by using the Naïve Bayes for making inference.
