Based On The Behavior Properties And Dependencies Of Bpel Similarity Measure Research

As the increasing using of Web Services Business Process Language (BPEL), it obviously increased the demand of retrieve the related BPEL instance in BPEL depository quickly. BPEL similarity retrieve technology is one of the important technologies in the field of BPEL depository managemant system. There are three BPEL similarity retrieve technology: node matching similarity, structure similarity and behavioral similarity. And the behavioral similairy is a very important retrieve technology.The similarity retrieval technology is not very efficient. Aiming at the issue, the paper proposes a similarity measure method which is based on BPEL behaviral attributes and BPEL dependency. The metric method based on JACCARD coefficient to calculate the overlap of BPEL behavior attributes and use the BPEL dependency behavior similarity weighting control. This metric distance function characteristics inherited JACCARD coefficient. This feature can significantly improve the retrieval performance metrics. At the same time the the BPEL behavior of properties precursor successor relationship from the macro level of similarity to describe, and the BPEL dependency granular correct similarity, the method is more accurate measure.The paper implements a simlilarity retrival tool, and takes a similarity experiment with the tool. The experiment results show that the similarity measure method can effectively improve the recall rate of the BPEL process, precision and execution efficiency. The similarity retrieval tool can be applied to the BPEL warehouse management system and effciency improve the BPEL management efficiency.
