Requirements are written in natural language and hence are subject to ambiguity, vagueness, and subjectivity. They are not always clear and coherent. They may also contain many duplicates and/or conflicting information. Automated solutions use information retrieval and machine learning techniques to capture such anomalies; however, current techniques ignore the semantics of the software artifacts or ignore integrating domain knowledge into this process and therefore tend to deliver imprecise and inaccurate results. In this research project, we would like to propose a solution that uses deep learning to incorporate requirements artifact semantics and domain knowledge into consideration. Our aim is to capture conflicting and duplicate requirements as accurately and timely as possible. We propose a network architecture that utilizes Word Embedding and Convolutional Neural Network (CNN) models to generate links. Word embedding learns word vectors that represent knowledge of the domain corpus and CNN uses these word vectors to learn the sentence semantics of requirements artifacts. We will build baseline methods using the Vector Space Model and Latent Semantic Indexing to compare and comply our proposed model with the state-of-the-art models as well as Watson Discovery. We will use datasets from DOORS Next Generation requirements. Our proposed model could further be extended to build the links between design requirements and source code to enable having a full traceability matrix.

要求以自然语言编写，因此要遵守歧义，模糊性和主观性。他们并不总是清晰且连贯的。它们还可能包含许多重复和/或相互冲突的信息。自动解决方案使用信息检索和机器学习技术来捕获此类异常；但是，当前的技术忽略了软件工件的语义，或者忽略将域知识整合到此过程中，因此倾向于产生不精确和不准确的结果。在该研究项目中，我们想提出一种解决方案，该解决方案使用深度学习来考虑伪影语义和领域知识的需求。我们的目标是尽可能准确，及时捕获冲突和复制要求。我们提出了一个使用单词嵌入和卷积神经网络（CNN）模型来生成链接的网络体系结构。单词嵌入学习词向量，代表域语料库的知识，CNN使用这些单词向量来学习需求伪像的句子语义。我们将使用矢量空间模型和潜在语义索引来构建基线方法，以将我们提出的模型与最先进的模型以及Watson Discovery进行比较和遵守我们所提出的模型。我们将使用下一代大门的数据集。我们提出的模型可以进一步扩展，以在设计要求和源代码之间构建链接，以使其具有完整的可食性矩阵。
