Abstract:
In this paper, we present a framework which provides runtime
adaptation for BPEL scenarios. The adaptation is based on (a)
quality of service parameters of available web services (b) quality
of service policies specified by users (c) collaborative filtering
techniques, allowing clients to further refine the adaptation process
by considering service selections made by other clients, (d)
monitoring, in order to follow the variations of QoS attribute values
and (e) on users’ opinions services they have used.
