ABSTRACT: GeoData Web service is an important way to achieve the
integration and sharing of heterogeneous geospatial data at present. However, due
to the complexity of GeoData and no sematic supporting Webservice discovery, it
is very hard for data users to accurately find the GeoData WebService they
really want. In order to make it easy for users to quickly and accurately find the
GeoData Web Service they want in semantic level, this article firstly, constructs
MetaData Ontololy, and uses MetaData Ontology to describe the related semantic
information for GeoData Web Service. Then it comes up with a new way of
computing the degree of semantic similarity among concepts based on Ontology.
Finally, it realizes the automatic discovery for GeoData Web Service based on
semantic matching. The experiment result shows that the way in this article can
dramatically improve the accuracy and intelligence of GeoData Web Service
discovery.
