Requirements Engineering Based on Domain Ontology

Requirements engineering is the foundation of software engineering, and quality of requirements engineering determines the quality of projects, while the traditional approaches do not meet the changing needs of the environment, it is difficult to describe by the unified and standardized form, but the ontology is a formal description of the concept of sharing, stressing the link between real entities, is the abstract of a specific exist, having sharing, reasoning function, etc.. The ontology applied to requirements engineering makes computer achieving understanding on the semantic level of information. This paper discusses the ontology related concepts and theories, puts forward the general framework of using an ontology needs analysis, and then uses example to illustrate how to use ontology needs analysis, validation and improvement.
