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具有可复用需求模式的支持工具。可重用需求规范的组件及其WWW表示：基于描述用例和场景的案例研究，我们提取了可重用的用例组件、用例模式和场景模式。对抽取过程进行了分析，提出了基于CASE文法的构件和模式的抽取和结构化技术，如参数化、泛化、聚合、数据和控制依赖、模式生成等。需求模式和工具的面向对象建模：我们将提取的模式捕获为一对它们的结构和重用它们的操作，并为它们开发了面向对象的建模技术。建模技术包括模式的组合和演化。此外，我们使用Java上的建模模式来开发和评估支持需求规范的工具，以便我们可以从WWW使用它。构建需求获取方法及其支持工具的计算机辅助工具：我们开发了一个计算机化工具，通过检索和组合www.com上现有的方法部分，来适应和构建适合于项目的新方法。构建的方法的支持工具是自动生成的，它们导航WWW页面上的需求获取活动，并调用方法图的绘图编辑器。

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.
