Ontology is playing an increasingly important role in knowledge management and Semantic Web. This study presents a novel ontology construction mechanism to extract domain ontology from existing Information System (IS) for constructing ontology-based knowledge management system. The IDEF5 ontology capture method is utilized to extract concepts, terms and statements from IS developing technology documents such as E-R diagram, data dictionary etc, which act as a starting point for ontology refinement and validation. Non-taxonomic relations and concept attributes can be generated from E-R diagram.
