A Dynamic Semantic Association-Based Web Service Composition Method

With the development of Web Service, it is critical to compose existing Web Services dynamically based on the need of users. This paper analyzes semantic association between services and proposes a dynamic web service composition approach based on Dynamic Semantic Association between services (DSAC). DSAC discovers the dynamic semantic of services when they are executing, integrates IO interface-match method and services? semantic relation ontology to get candidate successive services. This semi-automatically method could get an optimized service matchmaking results, ensure efficiency while composing services. The prototype and experiments show that DSAC can help user select proper services simply and is quite feasible for solving problems with real world sizes.
