Abstract
In a service-oriented environment, clients can usually choose between several web services offering the same functionality. The web service selection can be automated by allowing clients to specify non-functional requirements such as quality of service. Clients should also be able to indicate how to make tradeoffs when some of these requirements cannot be met. The ability to capture tradeoff preferences is critical for selecting the best fitting web service. In this paper, we propose a method of expressing non-functional preferences, which requires minimal effort on the part of the clients, but offers great flexibility in managing tradeoffs. This method leads to a simple algorithm for selecting web services, which does not require sophisticated multicriteria decision techniques.
