中文摘要: 服务组合模型构建是空间信息服务组合中最关键的步骤,构建的自动化程度则是空间信息服务组合技术推广应用的决定性因素。目前基于工作流的空间信息服务组合模型构建技术解决了模型的形式化表达问题。但需要领域专家参与的模型手动/半自动构建模式严重阻碍了空间信息服务在应用领域的推广应用,迫切需要发展模型自动构建的理论与方法。本项目以智能规划技术为基础,1)参照规划操作的描述规则,研究基于状态的空间信息服务描述模型;2)分析空间信息应用领域已有的各种粒度的服务、数据产品起源信息等所蕴含的业务流程,研究从中提取任务分解方案的方法;3)以规划问题的描述为基础,研究服务组合模型构建问题的形式化表达方法;4)研究模型构建问题的规划求解以及根据规划结果生成服务组合模型的方法。项目的研究将形成一套完整的空间信息服务组合模型自动构建方案,有助于推动目前手动、半自动建模向自动化方向发展,促进空间信息资源的共享与应用。

英文摘要: Service composition modeling is the key step in the implementation of geospatial service composition. The automation of modeling will remarkably broaden the application of geospatial service composition. The existing researches on workflow-based geospatial service composition modeling have provided some practicable methods to formally describe service composition models. But these manual/semi-automatic modeling methods are too complicated for inexperienced users, which has limited the application of geospatial services composition. Researches on automatic modeling theories and methods are needed. Based on intelligent planning, the following aspects will be studied in this program: 1)the representation of geospatial service compositions modeling problem; 2)the generation of state-based operation based on geospatial services description; 3)the extraction of task decomposition methods from geospatial processes; 4)the construction of geospatial service compositions model based on planning result. In this program, an automatic geospatial service composition modeling solution will be carried out. As the manual/semi-automatic modeling of geospatial service compositions is upgraded to automatic modeling, the application of geospatial services composition will be promoted.
