Abstract:

In the composition of Web Services, if the reuse is extended to a courser granularity than Web Services, that is, in BPEL processes’ level, and some process templates are generated, then, the developers can directly construct new business processes based on these templates, as a result, the efficiency and accuracy of the development of BPEL processes are improved. To achieve this, a method is proposed: converting the generation problem of process templates to the discovering problem of trees’ frequent patterns. Firstly, a whole BPEL process is modeled as a rooted unordered tree; then, frequent induced sub-trees are mined out based on TMG (Tree Model Guided); finally, frequent sub-trees are mapped back to BPEL process templates. A tool named ROY-BPELTool is implemented in java for generating process templates for BPEL, and BPEL processes of a real multimedia conference system run on it. Experiment results show the method’s validity.
