中文摘要：

为了解决传统的以应用领域为目标、以问题解决方案为中心的需求分析方法造成的开发人员与需求人员以及客户三者之间的误解,需求分析不可再次使用进而导致系统开发效率低下,客户满意度低等问题,文中提出了基于本体面向问题进行需求分析的方法。阐述了基于本体面向问题进行需求分析的必要性、本体的相关概念和设计原则、本体的描述语言以及基于LAU建立领域本体的实例与需求分析过程,并论证了利用该方法可进一步提高需求分析的质量。

英文摘要：

The traditional requirements analysis takes the application domain as the goal and takes the solution of the questions as the center, which induces the misunderstanding among developers, requirement analyzers and users and the result of requirements analysis is non - reusable and ulteriorly causes the system development＇s efficiency and the satisfaction degree of customers low. To solve these problems, proposed a based on ontology and problem - oriented requirements analysis. Expatiates the necessity to carry on the based on ontol- ogy and problem - oriented requirements analysis, the related concepts, the principles of design and description language, offers the domain ontology instance using LAU and the process of requirements analysis and demonstrates that the based on ontology and problem - oriented requirements analysis can improve the quality of requirements analysis.
