Web service composition is a topic bringing several issues to be resolved. Our work deals with the effectiveness and scalability of service composition. During composition we consider QoS and pre-/post-conditions of single services to create a composite service satisfying the user needs the best. Regarding pre-/post-conditions we propose an approach to fast determination of which services produce results expected by the user, i.e. the post-condition of which services implicates the desired condition defined in the user goal. This paper presents also a renewed version of our approach to QoS aware service composition. We achieved a dramatic improvement in terms of composition time by performing a useful restriction on the service space.

SummaryThe software‐as‐a‐service layer of cloud computing has evolved much interest among the researchers in the academic and industry worlds. It is based on service‐oriented architectures and web service (WS) technology, which are used to offer a remotely accessible application. When a single WS is unable to satisfy all the customer's requirements, a WS composition (WSC) method is applied to connect together various available WSs for building distributed application, using discovery, compatibility checking, selection, and deployment steps. This paper has two‐fold contributions: The major one is the proposition of a new algorithm based on minimally unsatisfiable subset formal algorithm to compose WSs. This contribution ensures a faster WSC, which is prominent in an online context. The second contribution is the proposition of a new penalty‐based genetic algorithm to identify near‐optimal solutions whenever an exact one is not identified using our formal algorithm. Indeed, in some cases, many available WSs provide overlapping/identical functionality; in this context, the choice of participated services is given using quality of service. This work proposes a WSC ensuring to find out an exact or a near‐optimal solution according to the user need. A set of experimentations is applied to validate our contributions.
