Building a Knowledge Base of Bridge Maintenance Using Knowledge Graph

To effectively manage the heterogeneous and discrete knowledge of bridge maintenance domain, this study adopts graph technology to build a base maintenance, called (BMKG). The BMKG uses an ontology as organization representation framework database storage tool. facilitate construction BMKG, hybrid method combining top-down approach bottom-up is proposed. Firstly, domain (BMDO) coded with Protégé represented in Web Ontology Language. Secondly, rule reasoning are implemented on BMDO order automatically complete missing relations or attribute values. Thirdly, adopted perform consistency check BMDO. Lastly, model stored Neo4j through data format conversion, thus completing BMKG. applied typical scenario demonstrate its application value. Results show that proposed can create realize transformation from into interconnected knowledge. Knowledge offers novel idea domain.
