Due to their complexity and the involvement of consumer’s fuzzy perceptions of QoS, non-functional QoS attributes are not easy to measure for web services. Hence, in order to enable effective QoS-aware web service selection, a new QoS web service selection approach, based on fuzzy synthetic evaluation, is proposed in this paper. The approach takes both functional attributes and non-functional QoS requirements into account for service selection. The approach has been empirically evaluated via a experiment. The results show that our proposed approach is effective under user’s vague perception.

Web service composition, that recursively constructs a composite web service out of the existing services based on a business workflow has been acknowledged as a promising approach to meet the user demands, whenever a single service alone cannot fulfil the needs. In view of frequent failures in the internet environment where the composed service is executed, reliability of the composed service must be ensured. The reliability is determined by the behavioral or transactional properties of component services. The component services for each activity of the workflow must be selected based on their behavior so that their execution results in a consistent termination. Service selection must happen at run-time in order to consider the services available in a service registry at the time of execution. Towards this need, a dynamic transaction aware web service selection approach is proposed in this paper. Further, whenever user requirements change, a long running transaction must be interrupted and cancelled which is not addressed by any of the existing works. Hence, service cancellability property is proposed in this paper and incorporated in the dynamic selection approach. The overhead of the proposed run-time selection approach is assessed and the impact of increased services on its performance is also measured.
