Research on Package-Oriented Requirements Engineering

1.开发同义词库的结构和构建技术：我们从互联网上收集了同一问题领域的软件包文档，并利用现有的自然语言处理工具提取了通用词汇表及其结构。我们使用基于词的句法分类和词在文档中出现频率的技术来提取通用词汇集。对于词汇表的结构提取，我们主要关注文档中的依赖关系出现情况和文档结构。基于面向目标的分析和使用已构建的特定于领域的同义词库开发需求引出方法：我们已经开发了一些方法来指导在面向目标的分析中使用同义词库的引出活动。我们发现它与想法生成方法和场景分析相结合，即集成方法更有用，并且更多地遵循同义词库的层次结构进行目标分解。通过使用同义词表中的词汇表来支持目标分解，通过使用词汇表之间的关系（强制关系和排除关系）来检测目标之间的不一致和缺失目标，以及将场景分析和使用词汇表词集的用例结合起来的技术已经开发出来，因为底层业务模型不同，所以从软件包获得的同义词表具有多功能性。如果我们组合并使用包含同义词库的单词，那么生成的需求文档可能包含不一致和冲突。为了解决这一问题，我们开发了统一多个干系人观点得出的目标图和通过干系人的优先级依恋来检测需求差距的集成技术。开发选择实现结构的方法：在上述方法中，我们开发并嵌入了基于在目标描述中出现同义词典单词的频率和顺序来选择合适的软件体系结构、框架和包的技术。少

1.Developing the structure of thesauruses and the techniques to construct them :We have collected the documents of the software package in the same problem domain from the Internet, and extracted the common vocabulary and its structure by using the existing natural-language-processing tools. We used the techniques based on classification of syntactic category of words and frequency of appearing the words in the documents in order to extract the common vocabulary set. As for extracting the structures of the vocabulary, we concentrated on the dependency relation occurrences in the documents and document structure.2.Developing requirements elicitation methods based on goal-oriented analysis and using the constructed domain-specific thesaurus :We have developed methodologies to guide elicitation activities using the thesaurus in goal-oriented analysis. We found that its combination with idea-generation method and scenario analysis, i.e. integrated methodology was more useful in addition to … More goal-decomposition following hierarchical structure of the thesaurus. The techniques of supporting goal decomposition by using vocabulary in the thesaurus, of detecting inconsistency among goals and missing goals by using the relation between the vocabulary (mandatory relations and exclusion relations), and of combining scenario analysis and use case one where the word set of the vocabulary is utilized have bee developed Thesaurus obtained from the software package has versatility because the underlying business models are different. If we combine and use words including the thesaurus, the resulting requirements document can include inconsistency and conflicts. To solve this problem, we have developed the integrated techniques of unifying the goal graph elicited from the multiple stakeholders' viewpoints and of detecting the gap of requirements by stakeholders' priority attachment.3.Developing the method to select an implementation structures :In the above-mentioned methodology, we have developed and embedded the technique of selecting suitable software architectures, frameworks, and packages based on the frequency and sequences of appearing the words of thesaurus in goal descriptions.
