Application Of Semantic Web Technology In Port Logistics

With the rapid development of global economic integration,more than 90% of the goods in global trade rely on port logistics to achieve transshipment.Port logistics has also become a major national strategy of our country.With the development of information technology,the mode of port logistics has been constantly changing,and the development mode has gradually moved closer to informatization.However,corresponding problems have also arisen.The knowledge resource data in port logistics is complex and huge,and it is difficult and cumbersome for users to obtain relevant knowledge resources,and the existing retrieval model cannot well identify and deal with the problems of users with semantic requirements.How to efficiently integrate and utilize knowledge resources in port logistics and provide users with high-quality knowledge resource retrieval services has become one of the hotspots in the construction of port logistics informatization.This article through to the study of the knowledge resource management retrieval of the port logistics,port logistics knowledge resources retrieval of user requirements,selection of port logistics accounted for the largest container business as the research object,the semantic web technology is introduced into the container of knowledge resources retrieval,build the container business knowledge resource ontology model,and analyze the relevant data,and specific applications,Through the introduction of the related entities case,using the ontology construction tool Protege,according to the container of the latest standards and global service center of the container on the logistics business of relevant data,using the ontology modeling language,to build a package with SPARQL query language and Jena reasoning technology of port container logistics knowledge resources question answering system,The intelligent management of domain knowledge resources based on ontology is realized.Users can quickly retrieve container-related knowledge resources in port logistics and promote the construction of port logistics information through the independent question and answer of semantic information.
