Understanding as We Roam

Increasingly, the problem for roaming users isn´t discovering local Web services or local context information or even getting their applications to intemperate with them at a syntactic level, but rather achieving interoperation at a semantic level. Developers are beginning to use semantic Web technologies such as ontologies to expose the semantics of context models and Web services.

This article describes a practical ontology-mapping process specified in the Unified Modeling Language, as well as its deployment
