A Context-Based Requirement Acquisition and Description Method

Requirement analysis, including requirement acquire and requirement description, is a process of determining user expectations for a new or modified software product. The process may also affect the others sectors in software development. The context is a fundamental and important object. It is a tool of formal concept analysis utilized in some areas. In this paper, we build a requirement acquire method called Combined Scenario and Viewpoint (CSV) method. The CSV can describe the correct requirements of system based on context. The experiments verify the method's effectiveness, feasibility and applicability.
