摘要:Requirements specification activity in a human-readable and formal representation is a crucial task while developing a complex system. If the meaning of requirements description and their fragments can be handled, Stakeholders can produce more effective requirement specifications of a higher quality. To that end, an ontology is developed to control capturing requirements in a formal way. The proposed ontology is built using Protege tool. This paper focuses on developing a generic ontology that can be used to define different concepts of requirements description. The suggested ontology can be used in many ways in analyzing requirements specification in any requirement engineering process. It would help system engineers to design requirement models susceptible to detect incomplete and conflicted requirements and a variety of other problems. It could also ensure consistency between many requirements specifications and increase communication between involved protagonists due to the use of the same terminology during all system specification process.
