The popularity of service oriented computing (SOC) brings a large number of distributed, well-encapsulated and reusable services all over Internet, and makes it possible to create value-added services by means of service composition. Current composition styles are too professional to those end users when building their own applications. Actually, the end user would prefer rapidly discovering the best-of-breed services to assemble as well as visually personalizing the presentation to enjoy rich experiences. We propose an end user service composition approach for reducing the composition complexity and difficulty from the end user perspective. In our approach, similar candidate services are aggregated together as a unified resource, whose wide QoS spectrum can be easily manipulated by the end users to satisfy their requirements. Then they can personalize the services and, the composition occurs only at the presentation layer. The main contributions of the approach are: (i) enabling the end users to personalize the composite application with more powerful presentation; (ii) supporting the end users to dynamically customize the service composition in terms of QoS; (iii) alleviating the end users from the time-consuming task of selecting service to compose.
