Process Semantic-Enabled Customisation for Active Service Provisioning

Service oriented architecture (SOA) promotes highly standardized, loosely coupled and Web-enabled services to foster rapid, low-cost and easy composition of distribute applications. Critical to SOA software development is to acquire users´ requirements and to provide service analysis and design techniques for identifying, conceptualizing, profiling, and rationalising service-enable applications. Semantic-enabled requirements engineering (SRE) for developing service-oriented applications helps to transform disordered users´ needs into ordered requirement specifications. It facilitates requirements acquisition with multiple stakeholders´ participation. It further enhances semantic-conducted services aggregation and eventually provides customized service productions according to process semantics of requirements. This paper concentrates on user-centric service customization with a paradigm shift from classical provider-centric service provision to user-centric active service production. Subscription and pushing technology of ATOM/RSS is adopted to actively push users´ needs to service providers. Semantic description of service requirements is proposed, and characterizes in identifying process (workflow) and service. A customized service production platform is designed to demonstrate its practicability and effectiveness.
