摘要:软件的功能描述文档是开发人员了解软件的重要基础.现有的软件项目并不都是具备全面描述软件功能的文档，但软件项目开发和应用过程中的各种交流记录蕴含了讨论其功能的大量信息.为此，提出了一种基于StackOverflow问答数据的软件功能特征挖掘组织方法.该方法提出以动宾短语形式描述软件功能特征，挖掘并组织蕴含在StackOverflow数据中的软件功能特征，自动生成一种以层次化方式展示的软件项目功能特征文档.在针对真实项目的实验中，该方法生成的软件功能文档可以覆盖官方文档中列举的97.6%的软件常用功能.同时，该方法可以扩展从不同形式的项目交流记录中生成全面描述软件功能特征的文档.



Abstract:Functional specification documents are very important for the developers who want to understand and reuse unfamiliar software libraries. Due to high cost of human effort and time, lots of software do not provide the official functional documentation. However, some software communication records produced in software developing processes contain valuable information regarding software functions and usages. In this paper, an approach is proposed to automatically mining and organizing functional features for open source software based on StackOverflow data. By describing functional features in the form of verb phrases, this approach generates hierarchical list of software functional features as the supplement of software documentation. In the experimental evaluation on some real-world subjects, the automatically generated documents have covered 97.6% of the frequent-used functional features in the official documents. At the same time, the proposed approach can be adapted to different types of software communication records, and applied to software in different domains.
