摘　　要：介绍了一种基于本体的服务发现组件设计方法,将基于本体的元数据和基于本体的查询结合起来,提高了基于OGC标准的网络地理服务发现的查询效率和准确性。An ontology-based component for geographic information discovery that solves the semantic heterogeneity problems of current query capabilities and improves the query efficiency and preciseness is introduced. A test case which is from the area of pollution of the environment shows that the request can be efficiently supported through subsumption reasoning.
