摘要
This paper presents a way to automatically compose web service workflow that uses component web services. The web services workflows are described using our transactional workflow ontology. The workflow ontology can be used to describe both component web service workflows and master web service workflows. We have also implemented a workflow engine that runs the workflow instances. Here we analyze using our ontology and some workflow instances with a reasoning agent to automatically find a composed workflow that fulfills all given constraints. The result from the inference is a workflow instance that can be executed using our workflow engine. We see that this kind of dynamic composition is needed in dynamic heterogeneous environments with loosely coupled web services.
