Semantic web enabled intelligent geospatial web services

Abstract

The paper introduces the semantic Web technologies into the fields of geospatial web services to research the three questions: Establishing a service-oriented geo-ontology model(SOGM) and extending OWL-S ontology to describe the semantics of geospatial web services; Designing a four constraints matching algorithm to discovery the large size geospatial web services quickly and efficiently; Designing a heuristic algorithm basing on weighted Graph Plan to compose atomic geospatial web services exactly. An experiment on remote sensing is conducted to validate the proposed approaches. The result indicates that the proposed approaches are valid for realizing intelligent geospatial web services. © 2011 Springer-Verlag Berlin Heidelberg.
