Requirements modeling is an important activity in software engineering and is more basic than other activities. But for scale domain, Requirements modeling usually suffers from limited knowledge of developers. In order to get a complete requirements model, software engineers have used domain ontology to capture requirements. However, previous approaches only can automatically capture requirements and the final software system is difficult to maintain. In this paper, we decompose old domain ontology into some sub ontologies and organize them into a tree model, which is called as Ontology Tree. Accordingly, we generate requirements model from Ontology Tree rather than old ontology. From real application, our approach shows a better development and maintainability of software.
