主　　题：geospatial information service link detection capability matching OWL-S ontology reasoning 

摘      要：Finding the right spatially aware web service in a heterogeneous distributed environment using criteria such as service type,version,time,space,and scale has become a challenge in the integration of geospatial information services.A new method for retrieving Open Geospatial Consortium(OGC)Web Service(OWS)that deals with this challenge using page crawling,link detection,service capability matching,and ontology reasoning,is described in this *** major components are distributed OWS,the OWS search engine,the OWS ontology generator,the ontology-based OWS catalog service,and the ontology-based multi-protocol OWS *** results show that the execution time of this proposed method equals only 0.26 of that of Nutch’s *** addition,the precision is much ***,this proposed method can carry out complex OWS reasoning-based *** is being used successfully for the Antarctica multi-protocol OWS portal of the Geo-Information Web Service Portal of the Polar.
