基于领域知识复用的需求建模

Requirements modeling based on domain knowledge reusing

为了准确地获取和复用军事电子信息系统需求,提出了基于领域知识复用的需求建模方法。介绍了利用领域知识进行需求建模的过程,利用目标模型表达用户需求,并通过复用领域知识建立目标模型;通过目标查询匹配和复用获取目标相关需求,建立应用本体;利用顶层本体概念与M E ISRDL业务框架的映射关系,根据应用本体生成需求模型。实例表明,通过复用领域知识,不仅保证了需求模型的质量,而且提高了需求建模的效率。

To elicit and reuse requirements of Military Electronic Information System accurately,the domain knowledge reusing based requirements modeling method was proposed.The requirements modeling process was presented in detail.Firstly,user requirements were expressed by goal model,which was constructed by reusing domain knowledge.And then the algorithm for goal query,goal model reusing and goal model enriching in domain knowledge were designed to construct application ontology.Finally,the requirements models defi...
