We take a broad view that ultimately Gridor Web-services must be located via personalised, semantic-rich discovery processes. We argue that such processes must rely on the storage of arbitrary metadata about services that originates from both service providers and service users. Examples of such metadata are reliability metrics, quality of service data, or semantic service description markup. T...

The Web services’ standards have some limits: UDDI provides a simple classification of Web services by sectors and WSDL doesn’t provide any Web services topologies’ description. Since these limits can influence Web services research’s results’ quality, this work aims to propose an approach that permits an optimised classification and a pertinent research of Web services. For that, we made some ...

Web services have created a platform-neutral environment for business processes to communicate. The number of companies using Web services is expected to grow exponentially. As such, the number of queries to name directory services, Universal Description Discovery and Integration (UDDI) registries, is expected to be very high. To facilitate high availability, UDDI version 3 suggests replication...

Web Services has emerged as a dominant paradigm for constructing and composing distributed business applications and enabling enterprise-wide interoperability. A critical factor to the overall utility of web services is a scalable, flexible and robust discover mechanism. This paper improves UDDI specification, thus it could guarantee usability of response and append grid-like monitoring informa...

Web service is a major trend in the industry for loosely coupled service-oriented architecture and interoperable solutions across heterogeneous platforms and systems. It receives profound attention and adoption by the industry as well as standard bodies. The traditional web service discovery is based on one-way request/response interaction pattern that a client (service consumer) makes a servic...

The web is moving from being a collection of pages toward a collection of services that interoperate through the Internet. A fundamental step toward this interoperation is the ability of automatically locating services on the bases of the functionalities that they provide. Such a functionality would allow services to locate each other and automatically interoperate. Location of web services is ...

The promise of dynamic selection of business services and automatic integration of applications written to Web Services standards is yet to be realized. This is partially attributable to the lack of semantics in the current Web Service standards. While efforts to develop markup languages , such as DAML-S, for semantic Web Services are a step in the right direction, more work needs to be done to...

Web Services for Remote Portlets (WSRP) provide solutions for implementation of lightweight Service Oriented Architecture (SOA). UDDI extension for WSRP enables the discovery and access to user facing web services provided by business partners while eliminating the need to design local user facing portlets. Most importantly, the remote portlets can be updated by web service providers from their...

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 XML and AI planning techniques and its underlying framework. This framework is design...
