Knowledge Management in Construction Health and Safety Based on Ontology Modeling

Knowledge management in construction health and safety is an intensive process involving different stakeholders. However, this domain's information is still fragmented and stored in various disordered formats that require systematic structure for reusing and sharing. This study aims to develop a domain ontology, HSM-Onto (Health and Safety Management-Ontology), to construct health and safety knowledge and improve health and safety management decision making. The HSM-Onto could implement the organization, storage and reuse of construction health and safety knowledge. It comprises two primary domain knowledge contexts, including construction project context and risk context. Based on the conducted analyses, the findings show that the HSM-Onto's health and safety knowledge sharing is effective and equips health and safety employees with sound recommendations for decision making.
