A Semantic-Based Web Service Integration Approach and Tool

Integration of Web Services for large-scale applications concerns complex processes. Component technology is an important way to decompose a complex process and promote efficiency and quality. This paper proposes a service integration approach considering both the integration of service flows and the integration of data flows. The approach includes the component-based Web Service process definition tool, mechanism for retrieving services in a well-organized service space and UDDI repositories, algorithms for heterogeneous data flow integration, and rules for service verification. The proposed approach has been integrated into an experimental service platform and used in an online book sale business application. Comparisons show the features of the proposed approach.
