Agent based workflow ontology for dynamic business process composition

OWLS (Web Ontology Language for Services) is being widely concerned of composing a Web service based workflow. However, a complete workflow should include both internal and external processes for their strong correlation that can be expressed by the logic power of the Web Ontology Language. Moreover, agent based workflow, from another point of view, provides a flexible mechanism for service discovery and dynamic workflow coordination at run time. This paper presents an agent based workflow ontology model for the purpose of semantic workflow building, reasoning, and process reconfiguration.
