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.
