Web services are emerging as a major technology for building service-oriented distributed systems. Potentially, various resources on the Internet can be virtualized as Web services for a wider use by their communities. Service discovery becomes an issue of vital importance for Web services applications. This article presents ROSSE, a Rough Sets based Search Engine for Web service discovery. One...

Web-based simulation requires the convergence of simulation methodology and WWW technology (mainly Web Service technology). The fundamental concept of web services is to integrate software application as services. Web services allow the applications to communicate with other applications using open standards. We are offering DEVS-based simulators as a web service, and they must have these stand...

Failures during Web service execution may depend on a wide variety of causes. In this paper we illustrate how, upon faults of a Web application, the faults can be handled by discovering substitute Web services and re-orchestrating the application. Self-healing capabilities are added to Web service environments. Possible recovery actions at the Web service and Web application levels are illustra...

This paper presents our research progress for group context-aware service discovery supporting continuous service availability by providing an alternative service. We believe that service discovery system need to have efficient method for representing the context of a service and a good algorithm for matching and evaluation. We adopt IOPE model from Semantic Web to represent service context and...

Current Semantic Web Service discovery mechanism consumes too much resource and lacks the ability to be used in real-world, large-scale situations. This paper propose a new kind of Semantic Web Service framework based on the concept of dividing the Semantic Web into different domains, and by introducing a kind of Semantic Web Service Router to help reduce the set of service description informat...

As a popular registry for Web services, UDDI provides a mature mechanism for service registration and search, but it does not support semantic operations on Web services, so its service discovery capability is not satisfactory. OWL-S overcomes UDDI’s shortcomings. Using OWL-S, service advertisements and requests based on capability description could be built in a uniform way, and the semantic m...

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.

In the current literature on service-oriented computing, the relationship between services and web-services is not always clear. Much research, notably in the area of service representation, discovery and composition, claims to address services whereas they actually apply to web-services. In this paper, we use insights from Language/Action Perspective and from value modeling to define 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...

Web service became one of the important methods for communication through the internet and its usage increased in the levels of users and developers. Semantic web service represents the second generation of web services that contains more description and information about its contents. Searching and dealing with web service is done through process called web service discovery which returns a Se...
