A social network model for construction safety knowledge sharing
Due to the complicated and complex working environments, construction site still presents high accident rate, which is causing serious project delay and cost overrun. Abundant studies have focused on cause and effect on fatalities or safety training system, and so on. Most of them on this issue have been emphasized the necessity and utilization of information, rather than how to exchange, share and transfer safety data efficiently in the construction industry. With this regard, this paper proposes the Social Network System for Sharing Construction Safety & Health Knowledge (SNSS), which utilizes state-of-the-art of semantic wiki web and ontology construction technologies for better communication and representation for construction safety information. The SNSS is developed on the basis of Safety Semantic Wiki Template (SSWT), which consists of the following three modules: 1) A Safety information module (SIM) which upload common accident and hazard information for sharing; 2) A Safety knowledge module (SKM) where the safety information is refined, confirmed and transferred to safety knowledge; 3) A Safety dissemination module (SDM) which allows its users to monitor, manage and retrieve safety information and knowledge easily. The SNSS is tested by a scenario of using falling accident information by which the potentials and limitations of the system were addressed. The study emphasizes the potential applicability and benefits of social network system that could be utilized to enhance communication among participants in the construction industry.
