With the growing adoption of service-oriented computing, locating services becomes increasingly commonplace. Accordingly, a large number of systems for service discovery have been developed. Although all these systems perform the same function, they do it in lots of different ways. Finding commonalities of and differences between these systems can be hard due to the lack of criteria to compare ...

A major problem for a grid user is the discovery of currently available services. With large number of services, it is beneficial for a user to be able to discover the services that most closely match their requirements. This report shows how to extend some concepts of UDDI such that they are suitable for dynamic parameter based discovery of grid services.

Service-oriented computing allows new applications to be developed by using and/or combining services offered by different organizations. Service composition can be applied when a client request cannot be satisfied by any individual service. In this case, the creation of a composite service from a number of available services could be pursued. This composite service should comply with the clien...

Service discovery and service composition are two crucial issues in the emerging area of Service-oriented Computing (SoC). The introduction of semantic annotations in Web service descriptions can support the discovery process of services and guide their composition into workflows. In this paper, we propose a Structured Relationship Algebra that extends existing frameworks for semantic service d...

This paper describes an ontology-based service discovery front-end interface for GloServ. GloServ is a service discovery engine, which is an ontology-based distributed service discovery system that allows sophisticated querying of services. The working implementation of the front-end interface demonstrates how GloServ can be used for different types of web service discovery. The front-end gener...

UDDI registries are included as a standard offering within the product suite of any major SOA vendor, serving as the foundation for establishing design-time and run-time SOA governance. Despite the success of the UDDI specification and its rapid uptake by the industry, the capabilities of its offered service discovery facilities are rather limited. The lack of machineunderstandable semantics in...
