Abstract. The concept of Service-Oriented Architectures (SOA) is the latest design paradigm for IT systems. The aim is to use Web services as the basic building blocks, which provide reusable functionalities that are invocable of the Internet. The initial Web service technology stack around WSDL, SOAP, and UDDI allows to technically realize the provision and usage of Web services. However, the support for the detection of the suitable Web services for a specific client application is limited to manual inspection. To better support this for SOA applications with larger numbers of available Web services which can be expected in realworld scenarios, the emerging concept of Semantic Web services (SWS) develops inference-based techniques for the automated discovery, composition, and execution of Web services. This article provides an overview on the SWS approach as well as the latest technology developments.

“…However, the automated composition is limited to sequential composition of atomic services, and composition requirements are limited to reachability conditions. Other automated planning techniques have been proposed to tackle the problem of service composition, see, e.g., [27,23]. However, none of these can deal with the automated synthesis problem that we address in this paper, where the planning domain and the generated plans are state transition systems, and goals capture composition requirements that are not limited to reachability conditions.…”

“…[12,4]), and much less emphasis has been devoted to the problem of process-level composition. Different planning approaches have been proposed to ad-dress the problem of on-the-fly composition, from HTNs [17] to regression planning based on extensions of PDDL, to STRIPS-like planning for composing services described in DAML-S [15]. However, none of these techniques addresses the problem of composing web services with conditional outputs, non-nominal outcomes, and with process models describing interaction protocols that include conditional and iterative steps.…”

Abstract. Most of the work on automated composition of web services has focused so far on the problem of composition at the functional level, i.e., composition of atomic services that can be executed in a single request-response step. In this paper, we address the problem of automated composition at the process level, i.e., a composition that takes into account that executing a web service requires interactions that may involve different sequential, conditional, and iterative steps. We define two kinds of process-level composition problems: on-the-fly compositions that satisfy one-shot user requests specified as composition goals, and a more general form, called once-for-all compositions, whose goal is to build a general composed web service that is able to interact directly with the users, receive requests from them, and propose suitable answers. We propose a solution to these two kinds of process-level compositions, and apply the solution to the case of web services described in OWL-S. As a result, we automatically generate process-level compositions as executable OWL-S process models. We show that, while executable on-the-fly compositions can be described as standard OWL-S process models, once-for-all compositions need OWL-S process models to be extended with receive and reply constructs.
