Frequently, in SOA, there exists no single service able to perform a given task, but there is a composition of services that can. In a continuously changing world, manual service composition is unrealistic and so is a fully automatic composition process: it is unreal to have a user specifying his request, pressing the magic button and waiting for the perfect solution. We believe that a certain degree of user involvement is required during the composition process while offering automatization when needed. This paper presents the overview of a user-centric approach for composing services into complex processes that are closest to the user’s specific needs. We distinguish between two phases: the automatic composition at the service capability level and the user’s contribution in refining the composition according to his specific requirements like domain specific QoS parameters at different granularity levels and the process structure.
