Abstract
Service Oriented Architecture (SOA) is becoming the architectural style of choice in many enterprises that adopt the notion of business process architecture. This suggests the need for a systematic and unified approach to generate a service model from a given organizational business process architecture. This paper presents a generic framework called BPAOntoSOA which addresses this requirement. BPAOntoSOA is ontology driven and guided starting from the business process architecture and using the quality of service QoSOnto ontology to ensure the proper alignment of the resultant services with the associated nonfunctional requirements. It is enriched by an associated domain specific ontology, for example, the healthcare sector. Also, this framework embodies a service identification process that implements an adapted affinity based clustering algorithm to enhance the correctness of mapping business functions to services in the resulting service oriented model.
