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.
