A semantic-based registry enabling discovery, composition and substitution of pervasive services

Abstract

In this paper we present a semantic-enhanced registry specifically devised for pervasive environments, able to cope with automated mobile service discovery and composition, compliant with OWL-S and with Semantic Web technologies. The proposed approach also deals with non-exact matches (computing an approximate result) and implements a dynamic substitution of services, especially useful in highly unpredictable contexts. It has been implemented and tested in a home/office automation case study, and we also report on experimental results.
