A semantic approach for more robust and efficient service discovery

Without a robust mechanism for integration of the various environments and their related ontologies it´s difficult to realize a ubiquitous environment in which mobile users and devices can seamlessly interact and acquire services. Therefore, if a robust and semantic mapping among the ontologies of different environments can be built then they can be integrated with each other. This paper proposes one such mapping of ontologies. This mapping technique maps semantic blocks within different ontologies to create a semantic matching of services. As compared to earlier approaches this approach is much more robust and flexible.
