摘要：In this paper, a systematic scheme of building semantic description of Geographic Processing Services (GPServices) based on ontology is proposed. According to the principle of ontology, GPServices taxonomy with multi-semantic-granularity is first built by extending taxonomy in ISO 19119. Then common semantics of GPServices instances are studied and summarized. After that, semantic associations between GPServices concepts, instances and properties of concepts and instances are analyzed and redefined based on Ontology Web Language (OWL) and Semantics Markup for Web Services (OWL-S). Finally, a model for GPServices semantics description is proposed by extending OWL-S. GPServices classification ontology and geographic information ontology is introduced to describe semantics of GPServices concepts and geographic information data in services parameters. GPService Quality ontology and GPService Security ontology are newly defined to represent GPServices instances semantics. With the proposed model, description of GPServices semantics can be built and express the meaning of GPServices to clients
