遥感信息聚焦服务的多层次语义约束模型

Hierarchical Semantic Constraint Model for Focused Remote Sensing Information Services

  • 摘要: 针对遥感信息服务中用户需求语义的复杂性,数据维度语义的丰富性,传感器语义的多样性,遥感信息处理语义的错综复杂性和遥感信息传输语义的时变性,从用户语义约束、数据语义约束、处理服务功能语义约束和处理服务质量语义约束等4个不同层次,建立多层次语义约束模型。

     

    Abstract: The challenge of remote sensing information service is complex in user demand,rich in data dimension,diversified in sensor types,complicated in processing and time-varying in network,which makes intricate in semantics.Therefore,we propose a hierarchical semantic constraint model as a uniform semantics description model with four levels including user semantic constraints,data semantic constraints,process service function semantic constraints,and process service quality semantic constraints.These constraints act role of establishing the connection between user semantics and data services and processing services,and of the basic of semantic reasoning in service discovery,selection,and composition.
