The increasing availability of web services demands for a discovery mechanism to find services that satisfy our requirement. UDDI provides a web wide registry of web services, but its lack of an explicit capability representation and its syntax based search provided produces results that are coarse in nature. We propose to base the discovery mechanism on OWL-S. OWL-S allows us to semantically d...

Success of Web services mainly depends on the availability of tools facilitating usage of technology within the addressed B2B integration problems. One severe problem in loosely coupled systems is service discovery including a sufficient matchmaking definition. The concept for service discovery in web service architecture is UDDI providing limited querying functionality and not being capable to...

One of the most serious challenges that web service enabled e-marketplaces face is the lack of formal support for expressing service requests against UDDI-resident web services in order to solve a complex business problem. We present a framework in which such a formalization is possible by integrating AI planning and constraint satisfaction techniques with web service technology. This framework...

This paper introduces a framework of interactive navigating through the web-based UDDI Business Registries. By creating a 2D interactive visual interface, service requesters are able to visually navigate through the large information hierarchies that are usually used to present the UDDI Business Registries. Instead of using the traditional keywords or click-through searching methodologies, whic...

According to the Service Oriented Computing paradigm, a lot of services have been recently implemented by several companies. Since the number of services are growing, tools able to aid people and software to look for a service are required. Current solutions, such as UDDI, even if compliant with the Service Oriented Computing paradigm, do not provide an efficient way to search for services, sin...

One of the most serious challenges that web-service enabled e-marketplaces face is the lack of formal support for expressing service requests against UDDI-resident web-services in order to solve a complex business problem. In this paper we present a web-service request language (XSRL) developed on the basis of AI planning and the XML database query language XQuery. This framework is designed to...

The key concept of Web services is to make both interand intra-application integration possible in a way that the integration does not depend on the platform or implementation of the service customer or provider. Since the information about Web services and their providers is usually managed in a central UDDI1 registry and the present UDDI standard does not offer a mechanism for the automatic a...

UDDI is a universal description, discovery and integration protocol. As a public registry of Web service, it is designed to store information about each company and its service. Traditional centralized service discovery structure of UDDI service registration center does not apply to largescale service discovery. When all the services register to a center, the service bottleneck, failure of sing...
