Research on Package-Oriented Requirements Engineering

1.建立主题词表的结构和构建技术：我们从互联网上收集了同一问题领域的软件包的文档，并利用现有的自然语言处理工具提取了常用词汇及其结构。我们使用了基于词的句法类别分类和词在文档中出现的频率的技术来提取常用词汇集。在词汇结构的提取方面，我们重点研究了文档和文档结构中出现的依存关系。2.开发了基于面向目标分析的需求获取方法，并使用构建的领域特定主题词表：我们开发了在面向目标分析中使用该主题词表来指导启发活动的方法。我们发现，它与想法生成方法和情景分析相结合，即集成方法论在…之外更有用更多的目标分解遵循叙词表的层次结构。已经开发了通过使用词库中的词汇来支持目标分解、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性和遗漏目标之间的不一致性、以及将场景分析与利用词汇表的词集相结合的用例一的技术，从该软件包获得的词汇表具有通用性，因为底层的商业模型不同。如果我们组合并使用包括同义词库在内的单词，得到的需求文档可能会包含不一致和冲突。为了解决这一问题，我们开发了统一从多个利益相关者的视角得出的目标图和通过利益相关者的优先关系来检测需求差距的集成技术。3.开发了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词库在目标描述中出现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。较少

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.
