An Approach for the Automated Composition of BPEL Processes

We describe a technique for the automated synthesis of new composite web services. Given a set of component services described as abstract bpel4ws processes enriched with semantic annotations, and given a composition requirement, we automatically generate an executable bpel4ws process that, once deployed, is able to interact with the components to satisfy the requirement. We focus in particular on the description of the annotations that we have to add to the abstract bpel4ws processes in order to capture the “semantic” aspects of their execution, and of the role that these semantic annotations play in the automated composition task.
