Context-based service recommendation for assisting business process design

The WS-BPEL provides a standard for business processes abstraction and execution, in which, the business processes abstraction is the key step for the completeness and success of business processes. The business processes abstraction includes the behavior and interactions between services which are sketched out by business processes designers. The current business process design is labor-intensive and time consuming, especially when it is required to be detailed to ensure the success of the business execution. In this paper, we propose an approach that helps the business process designers facilitate the design step by providing them a list of related services to the current designed model. We propose to capture the requested service's composition context specified through the process fragment surrounding it and recommend the services whose composition context in existing designed service compositions best match the given fragment context. Provided experimental evaluations in this paper show that our approach is efficient in realistic situations.
