Computer science Nowadays, metabolic pathway prediction is the focus of numerous drug discovery researches and is central to the stage of many biopharmaceutical and genomic companies. The identification and validation of drug targets depends critically on knowledge of the metabolic pathways in which potential target molecules operate within cells. To understand the cellular function, most scientists and biologists study parts of metabolic pathways that contain various types of pathways and large volume of knowledge including genes, enzymes, chemical compounds, and reactions that interlinked with each other. Thus, in order to provide better access to relevant knowledge, the knowledge of metabolic pathway should be conceptualized and formalized using appropriate knowledge representation technique.

To enhance the efficiency in predicting metabolic pathways, Problem Solving Method approach is proposed to perform the ontology inference by providing the reasoning component to solve the prediction problem of metabolic pathways.
