Research on Service Usage Pattern Mining Method in the Distributed Context

Composite service selection is a research difficulties in service-oriented computing domain. Most selection approaches are based on service QoS information which is difficult to acquire accurately. In this paper, a distributed Web service usage pattern mining infrastructure based on services execution information is proposed. In order to meet the cross-organizational associated business requirement, a service registry federation mechanism is presented. Then, a distributed algorithm of composite service frequent sequential mining within registry federation is described. In the end, some simulation results are demonstrated to show the effectiveness of the proposed method.
