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.
