一种基于映射机制的水利信息资源检索方法

Water conservancy information retrieval method based on mapping mechanism

在水利信息资源元数据统一检索过程中,针对水利信息资源元数据模式的多样性导致的语义不一致和用户资源视图展示需求不一致的问题,文中提出一种双重映射机制,通过语义关系映射解决不同类型元数据语义不一致的问题,通过视图关系映射解决用户资源视图按需配置问题。文中设计与实现的两种关系映射模型灵活高效、可扩展性强,有效地解决了上述两种问题。

To solve semantic inconsistency and user view resource display inconformity problem,which caused by the diversity of the metadata schema in the discovery process of water conservancy resource,this paper proposes a dual-mapping mechanism. The mechanism solves the semantic inconsistency issue of different types of metadata by semantic relation mapping and solves the on-demand configuration of user resource view issue through view relation mapping. It designs and implements two efficient,flexible and expansible relation mapping models,which effectively solve the existing problems of water conservancy data.
