Towards Quality of Experience Driven Service Composition

Web service composition enables seamless and dynamic integration of applications on the web. Generally a user has to find services, select proper services and form a flow to create a service composition. The performance of the composed application is determined by the performance of the involved Web services. Current work in web service selection and discovery are based on non-functional, quality of service (QoS) aspects (such as, response time and availability). However, QoS information does not reflect an end user´s perspective on the quality of services. An end user´s perspective of a service is a credible source of information, covers diverse platforms and geographical locations. In this position paper, we provide an approach to extract a user´s perception of the quality of services from user reviews on services and use such information to compose services. We provide a mechanism to select a particular service from a pool of services and recommend the best service execution path in a composite service.
