Semantic Interoperability: A Metadata Mediator Approach
Abstract
In this paper, we present a metadata mediation approach to intelligent integration of semantically heterogeneous geographical information (GI). Based on formalized metadata and expert system technology, the system can understand metadata of GI, represent explicit metadata knowledge, and use metadata mediator to automatically detect semantic conflict and resolve them. Furthermore, the prototype of metadata mediator has been given in this paper.
Keywords: Semantic interoperability, metadata, mediator
