Ontology-Based Model of Mobile Knowledge Service for the Inspection of Construction Project

Applying mobile knowledge service into construction project inspections meets the inspection workers´ knowledge demands of mobility and personality, enhances the efficiency of inspection works, and reinforces the pragmatic value of knowledge management in construction project business. User and task contexts are been paid more attentions in order to provide personalized knowledge service in mobile knowledge service. The hierarchy architecture of context ontology can be built simply and availably by ontology theories which study conceptual entities and connections among them in certain areas. The context ontology model of knowledge service in construction inspection describes the relationships between users and tasks, and the registration model of knowledge service is presented according to mobility and personality of project inspections. The OWL is used to delineate models of context ontology and knowledge service registration, which not only simplify the context expression, but also increase the validation and extensibility of knowledge registration services, and more sensibly reflect the adaptability and feasibility of ontology.
