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 services are becoming the dominant paradigm for distributed computing and electronic business. This has raised the opportunity for service providers and application developers to create value added services by combining web services. Several web service composition solutions have been proposed, e.g. BPEL4WS. However, these approaches are either not flexible or too complicated as they lack p...

Recently, the advance of service-oriented architectures and peer-to-peer networks has lead to the creation of service-oriented peer-to-peer networks, which enable a distributed and decentralized services market. Apart from the usage of single services, this market supports the merging of services into new services, a process called service composition. However, it is argued that for the time be...

In this paper, we present an approach to solve the problem of provably secure execution of semantic web service composition plans. The integrated components of this approach include our OWL-S service matchmaker, OWLSMX, the service composition planner, OWLS-XPlan, and the security checker module for formally verifying the compliance of the created composition plan to be executed with given data...

A lot of work has been done on the geospatial service composition to support advanced processing, spatial calculation, and invoking of heterogeneous data. However, the quality of service chain is rarely considered and the process model cannot be reused. A modeldriven way of geospatial web service composition is proposed in this work, the service composition is treated as an optimization problem...

In this paper, we present a framework for automatic selection and composition of services which exploits trustworthiness of services as a metric for measuring the quality of service composition. Trustworthiness is defined in terms of service reputation extracted from user profiles. The profiles are, in particular, extracted and inferred from a social network which accumulates users past experie...

The composition of web services is a promising approach enabling flexible and loose integration of business applications. Numerous approaches related to web services composition have been developed usually following three main phases: the service discovery is based on the semantic description of advertised services, i.e. the functionality of the service, meanwhile the service selection is based...
