Build Context-based Reasoning Space for Web Service Composition

Dynamic description logic (DDL) is among the few emerging service composition solutions through logical reasoning in AI area. To increase DDL reasoning efficiency, we proposed a new DDL-based service composition model that supports context-aware service pre-filtering over DDL reasoning space. In this model, service filtering based on contexts runs under the workflow control logic. We evaluated filtering approach on a simple, yet realistic example, and the results shows this approach provides a practical solution.
