An integrated framework for adapting WS-BPEL scenario execution using QoS and collaborative filtering techniques
We present an algorithm combining QoS and collaborative filtering for BPEL adaptation. The combination introduces collaborating filtering functionality maintaining high QoS. We exploit the sparsity of the rating matrix to tackle known issues of CF. We evaluate the approach both in terms of performance and adaptation QoS.
