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.

“…As noted in [6], the automation of WSC requires a machineinterpretable description of the services, and a reasoning system to select, combine and execute them. OWL-S [7], a big step in such a direction, provides Web services with richer semantic descriptions and specifies them as processes that have inputs, outputs, preconditions, and effects (IOPE).…”

The automation of Web service composition (WSC) has emerged as a major research topic since an ever-increasing number of Web services are created and published, which make manually analyzing them and creating the desired composite service difficult, or even beyond human abilities. This paper presented an approach for the automation of WSC at the functional level based on dynamic description logics (DDLs), extensions of description logics (DLs) with a dynamic dimension. By embracing knowledge in actions into DLs, DDLs couple the static information provided by ontologies and the dynamic processing provided by Web services, and offer a uniform way to represent and reason about both static and dynamic aspects of the Web content. Our approach employed classical DL-TBoxes to capture the constraints of the domain, DL-ABoxes to describe the states, and DL-formulas to encode the client requirements respectively. Actions in DDLs were used to abstract the functionalities of the existing Web services which were classified into categories in terms of their functionalities. In such a way, the WSC was reduced to formula satisfiability and solved by a decidable tableau procedure. We also implemented a reasoning engine based on the dynamic description logic D-ALCHOQ, and tested our approach on a simple variation of the travel scenario; the preliminary results certified the potential of the approach.

“…Further work was done on pre-/post-conditions of web service composition [8][9][10][11][12]. The study of the importance of user constraints and preferences revealed interesting impact on web service composition patterns [13][14][15]. Consideration of the user context and complex dependencies between services and the transactional behavior of Web service compositions was also studied.…”
