Abstract

The high prevalence of respiratory diseases in Indonesia has driven the government to implement various policies, such as strengthening primary healthcare services and promoting early detection programs, in order to reduce the morbidity and mortality associated with these diseases. As a solution to support early diagnosis, this study compares two approaches, namely Ontology and Certainty Factor (CF) Algorithm to diagnose respiratory disease symptoms. The method used involves the implementation of Ontology as a structured representation of medical knowledge, where relationships between symptoms, diseases, and other clinical concepts are formally defined to enable semantic reasoning. In parallel, the Certainty Factor (CF) approach is applied to incorporate expert knowledge by quantifying the degree of confidence or belief in a particular diagnosis based on observed symptoms. The results of the experiment show that both approaches are able to identify respiratory diseases, but with different results. Ontology is superior when compared to the CF algorithm. The CF algorithm is highly dependent on the accuracy of the certainty value provided by experts, making it susceptible to subjectivity. Meanwhile, the ontology approach produces a more consistent diagnosis because it is based on a systematic information structure. Based on these findings, Ontology is recommended as a more stable alternative for respiratory disease diagnosis support systems.
