Ontology-supported processing of clinical text using medical knowledge integration for multi-label classification of diagnosis coding

This paper discusses the knowledge integration of clinical information extracted from distributed medical ontology in order to ameliorate a machine learning-based multi-label coding assignment system. The proposed approach is implemented using a decision tree based cascade hierarchical technique on the university hospital data for patients with Coronary Heart Disease (CHD). The preliminary results obtained show a satisfactory finding. Keywords-component; medical ontology, diagnosis coding, knowledge integration, machine learing, decision tree.
