摘要
地理信息资源间丰富的关联关系可以为智能化资源检索提供知识基础,但由于地理信息资源多源异构的特点,资源之间普遍缺乏关联。目前虽然有研究已经考虑到资源间的关联关系,但因关联关系的抽象性,使得其认知效率不高,因此,需要对关联关系的可视化进行深入研究。本文通过挖掘资源之间的关联关系,使其应用于地理信息资源的检索中,其中关联关系的可视化设计是研究的重点,在此基础上设计地理信息资源可视化平台。
Rich relationship between geographic information resources can provide knowledge base for intelligent retrieval, but due to the characteristics of multisource and heterogeneous between geographic information resources, resulting inlacking connection between resources. Current researches are already considering the relationship between the resources, but due to theabstractnessof correlation which makes its cognitive efficiency is low, so we need to conduct the thorough research to the relationship of visualization. In this paper, we mine the relationship betweenresources, and make its application in the geographic information resources retrieval. The design of the visualization ofrelationship is the key of the research, anddesign geographic information resources visualization platform.
