摘　　要：针对当前航海书表内容实体数据建库工作面临的数据量大、人员有限、信息融合难度高等现实问题,在分析航海书表资料内容现状的基础上,结合当前航海书表实际生产流程,设计了三套实体数据库构建方案,并在分析各个方案优缺点的基础上,总结了各个方案的适用条件以及目前情况下的最优方案。经分析,该最优方案能够在目前有限的资源投入情况下,以现有和未来一定时期内规划的人力和设备资源,在不影响正常产品生产任务的基础上,完成航海书表实体数据库的构建工作。According to the realistic problems during the construction work of navigational publications’ entity database, such as large volume of data, limited staff, and difficulty of information fusion etc., this paper designs three construction methods, which are based on the contents and the production process of navigational publications. Then, these methods’ advantages and disadvantages are analyzed. The applicable conditions are summarized and the optimal method is finally proposed for this situation at present. After analysis in this paper, the optimal method can construct the entity database with limited resources and the normal production tasks of navigational publications will also not be affected.
