Mobile Grid Service is the extension of Grid Service. It is defined as: it is an intelligent code service wandering in grid nodes to accomplish certain task and provide certain service. Mobile Grid Service provides a series of standard interfaces and conforms specific conventions to solve such problems as: mobile service discovery, dynamic service creation, lifetime management, notification, mo...

Despite the widespread adoption of web services, several obstacles still hinder their smooth automatic composition. First, techniques that exploit semantic information during web services discovery are still lagging behind despite multiple initiatives like OWL-S. Second, the context in which web services evolve is, to a certain extent, ignored. This prevents deploying adaptable web services. In...

Searching for web services is a challenging task due to the diversity of existing discovery tools. Varying standards for service descriptions require adequate tools to query their content. However, these standards exist for good reasons. Web services are used in di erent application environments, unique solutions are therefore required for their integration. We suggest an architecture for a web...

Semantic Web Services are a research effort to automate the usage of Web services, a necessary component for the Semantic Web. Traditionally, Web service discovery depends on detailed formal semantic descriptions of available services. Since a complete detailed service description is not always feasible, the client software cannot select the best service offer for a given user goal only by usin...

Web service discovery aims at finding available services that match a given service description. This involves mainly the matchmaking of the functional parameters of the services, whereas non-functional attributes can also be considered and aggregated in the matching score of a candidate service as additional criteria for ranking the results. In this paper, we address the problem of re-ranking ...

This paper presents a research initiative, which aims at developing replication mechanisms for the dynamic management of the content of several Universal Description, Discovery, and Integration (UDDI) registries (Curbera et al., 2003). These replication mechanisms are intended to be deployed in an environment of Web services (Papazoglou & Georgakopoulos, 2003). By content of an UDDI registry, w...

This paper tests the ability of the Web Service Modeling Ontology (WSMO) and the Web Service Modeling eXecution environment (WSMX) to support the Semantic Web Services technology, and automate the process of web service discovery, selection and invocation. First, it introduced web services and their limitations that were overcome in the vision of the Semantic Web Services technology. Then a Sem...

In this paper we present an architecture that augments existing semantic-based web service discovery solutions. The idea is to combine principles from the semantic and pragmatic web in order for the web service selection process to become more efficient and effective. We utilize offer and request xml files to describe the functional properties (inputs/outputs) and context parameters of web serv...

The Web has changed from a mere repository of information to a new platform for business transactions where organizations deploy, share and expose business processes via Web services. New promising application fields such as the Semantic Web and Semantic Web Services are leveraging the potential of deploying those services, but face the problem of discovering and invoking them in a simple way f...

Semantic Web technologies offer the prospect of significantly reducing the amount of effort required to integrate existing enterprise functionality in support of new composite processes.– whether within a given organization or across multiple ones. A significant body of work in this area has aimed to fully automate this process, while assuming that all functionality has already been encapsulate...
