Material is the foundation of engineering construction, and materials service safety assessment is an important issue for public security. The data required for materials service safety assessment have the characteristic of multi-source and geographic related. According to this characteristic and the demand of service safety assessment, ontology-based materials service safety assessment system (OMSA) is proposed to provide a unified semantic model based on ontology and a visual assessment tool based on GIS for materials service safety assessment. Ontology building, ontology-based semantic query, and GIS are the key technologies for design and realization of safety assessment system. Thereby, the combination of these technologies may take respective advantages for materials service safety assessment, and latent semantic information of material service performance data can be explicitly shown in the visual GIS environment. |
