【摘要】 软件包括软件文档和源程序代码,发现和维护软件文档与源代码间的关联关系,对程序理解、软件维护、需求跟踪等许多软件工程活动提供很大的帮助。本文提出了一种提取中文软件文档与源代码间的关联关系的方法,根据中文软件文档和源代码的特征,在潜在语义索引模型的基础上使用了三种策略:引入项目数据词典辅助中文分词和中英文的翻译、将文档按类型分层以实现反馈、调整代码中的特征项的权值。实验结果表明,三种策略可以在提取阀值C相同的情况下,提高查全率10%～30%;在查全率不变的情况下提高查准率5%～20%。更多还原

【Abstract】 Software includes software documentation and source code.So the discovery and maintenance of the relationship between software documentation and source code give great help to program comprehension,software maintenance,requirements traceability and many other activities.In this paper,we propose a retrieval method for traceability links between source code and Chinese documentation,according to several features of Chinese software documents and source code.Based on the latent semantic indexing model,we use three strategies to improve:hierarchical enhancement,identifiers classifying,data dictionary.Experimental results show that the three strategies could increase the recall by 10% to 30% under the same extracted threshold and the precision by 5% to 20% under the same recall.更多还原
