protocol-aware matching of web service interfaces for adapter development
With the rapid growth in the number of online Web services, the problem of service adaptation has received significant attention. In matching and adaptation, the functional description of services including interface and data as well as behavioral descriptions are important. Existing work on matching and adaptation focuses only on one aspect. In this paper, we present a semi-automated matching approach that considers both service descriptions. We introduce two protocol-aware service interface matching algorithms, i.e. depth-based interface matching and iterative reference-based interface matching. These algorithms refine the results of interface matching by incorporating the ordering constraints imposed by business protocol definitions on service operations. We have implemented a prototype and performed experiments using the specification of synthetic and real-world Web services. Experiments show that the proposed approaches lead to a significant improvement in the quality of matching between services.
