Natural language based component extraction from requirement engineering document and its complexity analysis

Abstract

Requirement engineering document (IEEE-830: 1998) plays a very significant role in software development. The size and complexity of software systems are continuously increasing. As scale changes to more complex and larger systems, new problems occur that did not exist in smaller systems This leads to redefining priorities of the activities that go into developing software. As systems ges complex, it becomes evident that the goals of the entire system can't be easily comprehended. Hence the need of more rigorous requirement analysis arises. The requirement analyst has to identify the requirements by using various methods like interviews, brainstorming, FAST (facilitated application specification techniques), quality function deployment, use-case etc. To overcome these issues, this paper proposes object based semi-automated system that categorize the requirements and further identifies the component based on requirement engineering document in a component library and further analyses the complexity of components and its usage.
