Abstract: 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.

Key words: service oriented architecture, semantic navigation, concept tree, corporate domain model
