面向本体的需求分析

Ontology-Oriented Requirements Analysis

提出了一种新的需求分析方法——面向本体的需求分析 OORA(ontology- oriented requirementsanalysis) .该方法的主要特点是 ,用本体作为对象关联的手段 ,以增强面向对象方法的表达能力 .文章首先定义了 OORA的需求模型 ,然后结合实例讨论了信息系统需求分析中的两种主要的本体类型 ,最后给出了 OORA方法的主要步骤 .

In this paper, the authors propose a new approach to requirements analysis, called OORA ( ontology oriented requirements analysis). The most important feature of this approach is that various ontologies have been introduced to represent relationships between objects and/or classes. These ontologies may significantly enhance the expressiveness of the current OOA (object oriented analysis) approaches. In this paper, first the OORA requirements model is designed. After that, two key types of ontologies are illustrated by two typical use cases. Finally, the main phases in OORA are given.
