Research on Geographic Information Services Semantic Annotation Based on OGC
摘要
Abstract
As geographic information services increase dramatically,it makes more difficult to discover,integrate and utilize them for us-ers. Also,users cannot obtain the objective data really needed. So,how to get the necessary GIS data service automatically,quickly and ac-curately is a challenge which needs to be solved urgently in geographic information semantic search field. However,much more service search is still based on the keyword matching. Semantic ambiguity and semantic deficiency bring out that users cannot get the really nee-ded service. In this paper,the semantic annotation method and workflow of OGC ( Open Geospatial Consortium) Web Service ( OWS) capability files is generated,and a prototype system based on semantic annotation is designed and developed. It is verified that semantic annotation method can enhance the precision ratio and recall ratio of OWS discovery.关键词
