“…This is because of the complex nature of the WSC problem and the inherent scalability issues in existing AI planners. Two exceptions are Synthy [46,47] and the Astro Project. 6 Synthy accepts WSs described in OWL-S and composes the WSs in two stages: The first stage composes an abstract workflow to satisfy the functional requirements, and the second stage chooses WS instances for the components in the abstract workflow, based on the QoS attributes of WS instances.…”

Automatically composing Web services to form processes in the context of service-oriented architectures has attracted significant research. Prevalent approaches for automatically composing Web services predominantly utilize planning techniques to achieve the composition. However, classical planning based approaches face the following challenges: (i) difficulty in modeling the uncertainty of Web service invocations, (ii) inability to optimize the composition using non-functional parameters, and (iii) difficulty in scaling efficiently to large compositions. In order to address these issues, we present a hierarchical framework for logically composing Web services, which we call Haley. In comparison to classical planners, Haley utilizes decisiontheoretic planning that is able to model and reason with the uncertainty inherent in Web service invocations and provides an expected cost-based optimization. Haley uses symbolic planning techniques that operate directly on first-order logic based representations of the state space to obtain the compositions. Consequently, it supports automated elicitation of the corresponding planning problem from Web service descriptions and produces a domain representation that is more compact than that of classical planners. Furthermore, it promotes scalability by exploiting the natural hierarchy found in real-world processes. Due to the limitations of the existing approaches and the complexity of the Web service composition problem, few implemented tools exist, although many approaches have been proposed in the literature. We have implemented Haley and provided a comprehensive tool suite for composing Web services. The suite operates on Web services described using well-known languages such as SAWSDL. It provides process designers with an intuitive interface to specify composition requirements, goals and a hierarchical decomposition if available, and automatically generates BPEL compositions while hiding the complexity of the planning and of BPEL from users.

Purpose -The purpose of this paper is to propose a novel quality of service (QoS)-aware service composition approach, called SEQOIA, capable of defining at run-time a service composition plan meeting both functional and non-functional constraints and optimizing the overall quality of service. Design/methodology/approach -SEQOIA is a semantic-driven QoS-aware dynamic composition approach leveraging on an integer linear programming technique (ILP). It exploits the expressiveness of an ontology-based service profile model handling structural and semantic properties of service descriptions. It represents the service composition problem as a set of functional and non-functional constraints and an objective function. Findings -The authors developed a proof of concept implementing SEQOIA, as well as an alternative composition solution based on state-of-the-art AI planning and ILP techniques. Results of testing activities show that SEQOIA performs better than the alternative solution over a limited set of candidate services. This behaviour was expected, as SEQOIA guarantees to find the service composition providing the optimal QoS value, while the alternative approach does not provide this guarantee, as it handles separately the specification of the functional service composition flow and the QoS-based service selection step. Originality/value -SEQOIA leverages on semantic annotations in order to make service composition feasible by coping with syntactic and structural differences typically existing across different, even similar, service implementations. To ease the adoption of SEQOIA in real enterprise scenarios, the authors chose to leverage on an XML-based message model of services interfaces (including but not strictly requiring the use of WSDL).
