摘要
针对大型信息系统需求的复杂性,从需求的元级概念出发,提出了元需求概念,分析定义了元需求的构成要素、要素间关系及特征;用模型的方法来表示元需求,构建元需求模型,并形式化地表示模型。引进本体概念,将元需求模型看做是一个本体,用本体网络语言表示元需求模型;借鉴本体构建方法,基于Protégé工具构建了元需求集。元需求模型及元需求集实现了需求获取与分析,为基于元需求的需求获取及分析提供基础。
According to the complex requirements of large-scale information system,this paper proceeded from the meta-level of requirements,defined the integrant part of meta-requirement and analyzed their relationships and characteristics.Based on model approach,it expressed meta-requirement（MR） as meta-requirement model（MRM） which was formally expressed.Then,based on ontology,it described the MRM by the ontology Web language（OWL）.And it introduced the Protégé tool to establish the meta-requirement set（MRS）.Finally,it applied the MRM and MRS to requirements acquisition and analysis.The research results provide foundation for requirements acquisition and analysis based on meta-requirement.
