This study introduces an Ontological Comparison Approach that addresses the difficulties in finding appropriate substitute courses for graduating students if their first choices are not offered. Department heads have always had to manually compare courses across different departments, which is time-consuming and error-prone. Our method allows customers to specify desired matching percentages by measuring the degree of matching between course descriptions using sophisticated algorithms. This approach greatly simplifies the procedure and improves the speed and accuracy of finding suitable course substitutes. Additionally, the strategy is enhanced by an intuitive user interface that helps make well-informed decisions, addressing the challenges of choosing courses in the pivotal last stages of academic programs.
