Semantic Lookup in Service-Oriented Architectures
نویسنده
چکیده
Lookup of services is an important issues in many distributed systems. This paper deals with lookup in service-oriented architectures, such as Web services, P2P systems, GRIDs, or spontaneous networks. Service-oriented architectures impose specific requirements onto the lookup service, for instance regarding the runtime extensibility of lookup models, runtime extensibility of lookup queries, construction of complex lookup queries, scalability, and fault tolerance. These requirements are not well solved by existing lookup approaches. We propose a semantic lookup service using Semantic Web ontologies, expressed in RDF. Query scripts are sent from the client to the server and are interpreted at server side using the RDF repository. We also present a safe, scalable, and efficient architecture for defining and querying lookup information using this lookup service concept.

Service Oriented Programming which combines Distributed Object Compunting, Component Based and webbased concepts has recently emerged as a promising approach to develop dynamic and heterogeneous service provision environments. Such systems are referenced in literature as Service Oriented Architectures. Classic strategies to address dependability in Distributed Object Computing middlewares may n...
متن کاملThe Semantic Side of Service- Oriented Architectures
In Service-Oriented Architectures (SOA), service descriptions are fundamental elements. In order to automatically execute SOA tasks, such as services discovery, it is necessary to capture and process the semantics of services. We review several Semantic Web Services frameworks that intend to bring semantics to Web Services. This chapter depicts some ideas from SOA and Semantic Web services and ...
متن کاملModels for semantic interoperability in service-oriented architectures
G. Vetere M. Lenzerini Although service-oriented architectures go a long way toward providing interoperability in distributed, heterogeneous environments, managing semantic differences in such environments remains a challenge. We give an overview of the issue of semantic interoperability (integration), provide a semantic characterization of services, and discuss the role of ontologies. Then we ...
متن کاملGeneric Component Lookup
The possibilities currently offered to conduct business at an electronic level are immense. Service providers offer access to their attendances through components placed on the Internet; such components can be combined to build applications, which can themselves be used as components by further business units. The final leg of the way to this paradigm has been paved by the advent of service-ori...
