| In this paper, an intelligent search engine system for marine geographic information based on knowledge map is established. vue+element-ui framework is adopted to design the front display layer, and nine subject query methods including disciplines, institutions, personnel, literature, information, data, models, terms and place names are designed. Use the springboot framework to build a back-end service layer for users, project design, modification, and management. On the basis of building the system, data collection and map construction are carried out. Firstly, multi-modal information related to marine geography such as literature, documents, maps and data is retrieved by selenium, and then the knowledge map is constructed and stored by using neo4j map database and Mysql relational database. Finally, some search examples are selected to experiment and verify the system. The experimental results show that the system can be well applied to the accurate query of professional information of marine geography. |
