Nowadays, considering Web Services has become one of the hot issues in the area of computer science that makes an ability to collect capabilities and components in a unique interface to fulfil the user’s requirements. Sometimes two or more services are discovered in available list of services; therefore, there should be a possibility for selecting the best services from discovered list which can satisfy the user’s goal. The selected services should optimize the overall QoS of the composed application, while satisfying all the constraints specified by the client on individual QoS parameters. In this paper, we propose an approach based on the notion of skyline to effectively and efficiently select services for composition and reducing the number of candidate services. At the end of the paper we evaluate our approach experimentally.
