To speed up creation of personalized requirements models for users, it is necessary to systematically model domain knowledge and specify a reuse mechanism to customize personalized requirements models. Based on a unified framework for requirements metamodeling named RGPS (Role-Goal-Process-Service), a goal oriented and ontology based approach is proposed in this paper to customization of requirements goal models based on domain knowledge. Particularly, Metamodel for ontology registration is introduced as a common facility to register goal models and promote semantic interoperation between them. Accordingly, a series of rules are designed to construct, refine and ultimately confirm requirement goal models. In order to demonstrate how our approach works, a case study in urban transportation domain is illustrated step by step to provide details of how to customize requirements goal models for users. In this way, well-modeled and registered domain goal models will be the foundation for constructing high-quality requirements goal models in a normative way.
