Towards an abstract architecture for service discovery with semantic alignment

In large-scale open environments mechanisms for locating appropriate services have to deal with the additional problem of semantic mismatches among the components. Semantic alignment mechanisms need to be purposefully integrated into a service discovery framework in order to fully exploit its potential. The objective of this paper is to present an ongoing work towards the analysis and design of basic mechanisms able to locate adequate services in open heterogeneous environments. An abstract architecture that addresses the semantic mismatches at service description model level as well as domain ontology is presented. Several open issues are pointed out.
