| 中文摘要: |
| 非功能需求描述系统质量相关的属性，是软件设计决策的重要依据和评估标准.与功能需求的描述相比，非功能需求描述通常比较分散，且往往是隐含的.当采集到的需求原始描述内容较多时，逐一进行人工判别和整理需要耗费大量的时间和精力.针对中文自然语言描述的需求文本，本文提出了自动化的非功能需求识别和分类方法.其中，识别过程旨在从文本中提取出可能包含非功能需求的语句，尽可能缩小人工检查的范围.分类过程则进一步将包含非功能需求的语句划分到性能、可靠性、可用性、安全性、可维护性等五大类非功能需求类型之中.本文的分类训练和实验测试基于课题组工作项目整理的实验数据集进行，最终基于一个工业界的实际应用案例数据，验证了方法的有效性. |
| 英文摘要: |
| Non-functional requirements state quality related expectations to a system, which are used as important criteria for software design decision making and design evaluation. Comparing to functional requirements descriptions, non-functional requirements statements are often scattered and implicit, which may require much effort to group and interpret manually. This paper proposes an automated non-functional requirements recognition and classification approach, which identifies the sentences that are likely to include information about non-functional requirements, to save manual efforts. Then we proceed to classify given non-functional requirements statement into five possible non-functional requirements types, including performance, reliability, usability, security and maintainability. The training of classification model and experiements are based on a requirements dataset from our past projects, and then the proposed approach is validated with an industrial project requirements data. |
