Marine Ecological Knowledge Management System Based on Ontology Repository

This paper researches semantic retrieval and ontology rule reasoning for marine ecological knowledge management system. Upper ontology plays a critical role in ontology development by giving developers a guideline to view the target domain. By fixing a viewpoint of device-function, we present a domain upper ontology for marine ecosystem, and then construct marine ecology ontology and ontology repository. Based on constructed marine ecology ontology repository, authors design and develop marine ecological knowledge management system, which implements main functions include marine ecological knowledge navigation, term query, knowledge retrieval and ecological crisis early warning. Marine ecology ontology application system provides users a semantic support platform for marine scientific research and cooperation, and it also verifies the rationality and feasibility of ontology modeling method and validity of constructed marine ecology ontology.
