The invention relates to the technical field of spatial information service, in particular to a semantic description method for a remote-sensing information processing service based on domain ontology. The method comprises the following steps of: determining the composition of a domain ontology of a remote-sensing information processing service; respectively establishing a remote-sensing information processing service classification ontology, a remote-sensing information ontology, a service quality ontology and a service safety ontology by using an ontology modeling tool, and expressing the domain ontology by using an OWL language; determining the semantic description content of the remote-sensing information processing service; expanding a semantic description model of an OWL-S service; and forming a semantic description model of the remote-sensing information processing service based on the domain ontology. By being combined with the domain characteristics of the remote-sensing information processing service, the method establishes the domain ontology of the remote-sensing information processing service and expands the OWL-S by using the domain ontology to form the semantic description model of the remote-sensing information processing service based on the domain ontology, thereby overcoming defects in the semantic description of the remote-sensing information processing service by the OWL-S in aspects of service quality, service safety and domain knowledge.
Description
technical field [0001] The invention relates to the technical field of spatial information services, in particular to a semantic description method for remote sensing information processing services based on domain ontology. Background technique [0002] From the late 1990s to the present, service-oriented architecture, as a distributed information system architecture, has been gradually introduced into various application fields including the field of spatial information science. As the mainstream implementation technology of service-oriented architecture, Web service technology has greatly promoted the sharing, interoperability and integration of spatial information in the form of services. At the same time, with the rapid development of earth observation technology, a large amount of remote sensing data and various remote sensing information processing functions are distributed on the Internet in the form of services, providing information sharing and interoperability amo...
