面向服务的企业数据语义导航

为了向企业的决策活动提供连续且有意义的数据视图，提出了一种以概念映射为基础的面向服务的企业数据语义导航方法。该方法首先基于概念树建立公共领域模型，并通过概念映射建立数据源数据、目标问题域模型与公共领域模型之间的语义关联关系；然后通过建立相互协作的数据导航和数据源包装两种Web服务，构建面向服务的企业信息导航体系。该体系根据目标问题域模型、数据源数据和公共领域模型的语义关系，通过Web服务之间的协作实现企业数据动态、松耦合的集成访问，从而获得语义一致的数据导航结果。

Service oriented semantic navigation of enterprise data

To offer successive and meaning data view for decision-making in enterprises, a new approach called Service Oriented Semantic Navigation of enterprise data based on Concept Mappings (SOSNCM) was proposed. First, public domain model based on definition-tree was constructed with this approach. And the semantic relationships among data source, object problem-domain model and public domain model were established through concept mapping. Then with construction of two Web services as cooperative data navigation and data source wrapping, the enterprise information navigation system oriented to service was set up. With the help of semantic relationships among data source, object problem-domain model and public domain model, dynamic and relax-coupled integration access of data across enterprises was realized via cooperation of Web services so as to achieve semantically coherent data navigation.
