Research on Support for Software Requirements Elicitation using WWW

本研究的目的是开发基于Web技术的软件需求获取方法及其支持工具，具有可重用的需求模式1。可复用需求描述的构件及其WWW表示：在描述用例和场景的案例研究的基础上，提取了可复用的用例构件、用例模式和场景模式。分析了构件和模式的提取过程，提出了构件和模式的提取和结构化技术，包括参数化、泛化、聚集、数据和控件依赖以及基于格文法的模式生成技术.面向对象的需求模式建模与工具：我们将抽取的需求模式作为一对结构和操作来复用，并开发了面向对象的需求模式建模技术。建模技术包括模式的组合和演化。此外，我们开发和评估的工具，以支持需求规格说明，通过使用Java模式，使我们可以使用它从WWW。用于构造需求获取方法和生成其支持工具的计算机辅助工具：我们开发了一种计算机化工具，用于调整和构建适合项目的新方法，通过检索和组合WWW上已有的方法部件，自动生成所构造方法的支持工具，它们在WWW页面上导航需求获取活动，并调用方法的图表。

The aim of this research is to develop software requirements elicitation methods based on Web technology and their supporting tools having reusable requirements patterns1. Components of Reusable Requirements Specification and Representing Them by WWW : Based out case studies on describing use cases and scenarios, we extracted reusable use case components, use case patterns and scenario patterns. We analyzed the extraction processes and developed the techniques how to extract and structure the components and patterns such as parameterization, generalization, aggregation, data and control-dependency and making patterns based on case grammar.2. Object-Oriented Modeling for Requirements Patterns and Tool : We captured the extracted patterns as a pair of their structures and operations for reusing them, and developed the object-oriented modeling technique for them. The modeling technique includes the combination and evolution of the patterns. Furthermore, we developed and assessed the tool for supporting requirements specification by using the modeled patterns on Java, so that we can use it from WWW.3. Computer-Aided Tools for Constructing Requirement Elicitation Methods and for Generating Their Supporting Tools : We developed a computerized tool for adapting and constructing new methods that are suitable for projects, by retrieving and combining the existing method parts on WWW.The supporting tools for the constructed methods are automatically generated and they navigate the activities of requirements elicitation on WWW pages and invoke the draw editors of the diagrams of the methods.
