A Goals-Driven Customizing Approach of Web Service-Based Software

In Service-Oriented Computing (SOC), personalized requirements from diverse user present challenges to develop software with lower cost and high degree of satisfaction. Due to the popularity and fundamentality of Web services (WS), WS-based software is born through SOC by dynamically linking and customizing Web Services resources in the Internet to meet users’ goals. This paper proposes a goal-driven approach for customizing WS-based software to satisfy diversity of users’ requirements. More specifically, a unified and service-oriented framework for requirements metamodeling is adopted to construct well-organized and interrelated domain assets as the basis for customization; and a goal-driven customization method for WS-based software is designed to support implementation of this approach. This is followed by a case study in the urban transportation domain that demonstrates in detail the feasibility of our approach.
