一种基于本体的地理多维语义信息组织方法

Method of organizing geographic multidimensional semantic information based on ontology

针对地理信息元数据的语义关联特性和多维特性,提出了一种组织地理信息的方法。基于本体论描述不同地理信息元数据之间的语义关联特性;在此基础上,通过维层次编码量化在本体中所描述的层次结构;通过X树组织和检索处理后的多维数据,最后给出应用实例,说明理论的可用性。

This paper presents a method of organizing and retrieving information of multidimensional and semantic geographic metadata.Firstly,ihe paper describes the semantic relationship among different geographic metadata with ontology.Then it encodes /he hierarchical information in the ontology. ~ith dimensional hierarehical coding,and moreover it organizes and retrieves multidi- mensional data using X-tree.Finally,this paper provides a case to show the method is practical.
