GIS Information Organization Based on Semantic Geospatial Web
People typically use geographic names instead of coordinates to find geographic information on the web through a search engine.But the current keyword-based web search engines are poorly adapted to help people find information that relates to a particular geographic name,because they dont incorporate the geospatial semantic during the search process.The Semantic Web is a new semantic-based information-retrieval environment.We propose the information organization framework of the GIS semantic data according to the architecture of the Semantic Web,that is,the ontology,the metadata and the data source.Then we deal with the organization of the semantic data based on the three-layered framework respectively.As a focus,we present a novel method to disambiguate geographical name based on the ontology of the place.
