Semantic integration of XML Schema
Yanfeng Zhang, Weiyi Liu · 2003
The availability of large amounts of heterogeneous distributed Web data necessitates the integration of XML data from multiple XML sources. As a common method for defining and validating highly structured XML documents, XML Schema is considered a logical model for XML. This paper describes how to convert XML Schema to UML diagram (conceptual model) for semantic integration and how to integrate conceptual models. Our integration process includes three steps: clustering of concepts, unification of concepts, and restructuring of relationships. Finally, a global conceptual model is provided for users.
