UCD-generator - a LESSA application for use case design

In object-oriented design, use cases are one of the important but complex components to design. UCD-Generator is a LESSA based application that makes this process more simple and easy. UCD-Generator is an automated system that has vigorous ability to directly interact wit the user. This research paper presents a natural language processing based approach LESSA that is used for automatically understanding the natural language text and extract required information. This information is used to draw the use case diagrams. User writes his interface based preferences in simple English in a few paragraphs and the designed system has conspicuous ability to analyze the given script. After compound analysis and extraction of associated information, the designed system actually draws the use case class diagrams. Other conventional CASE tools require a complete understanding of the intended business scenario and lot of extra time and efforts from the system analyst during the process of creating, arranging, labeling and finishing the USE case diagrams. The designed system provides a quick and reliable way to generate use case diagrams to save the time and budget of both the user and system analyst.
