Natural Language Processing for Scenario based UML Diagrams Generation

This paper presents a natural language processing based automated system for generating UML diagrams after analyzing the given business scenario. A new model is presented for analyzing the natural languages and extracting the relative and required information from the given storyline by the user. User writes the requirements 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 draws various UML diagrams as activity diagrams, sequence diagrams, class diagrams and Uses cases diagrams. Other conventional CASE tools require a lot of extra time and efforts from the system analyst during the process of creating, arranging, labeling and finishing the UML diagrams. The designed system provides a quick and reliable way to generate UML diagrams to save the time and budget of both the user and system analyst.
