Textual Requirement Analysis for Object Model Designing by Using NLP

Software development is a complex process and begins with requirement gathering. Requirements are specified in their natural forms and are required to be converted into formal specifications such as object diagram for further use in any software development process. These diagrams are useful for clearly understanding the problem definition of software and other documentation purpose. This paper aims at developing specialized tool for generating class diagram and usecase diagram from requirements specified in natural language. For this purpose we present a new methodology to develop object diagram from natural language requirement specifications named RAUE. We present a new methodology for generating UML diagrams or models from natural language problem statement or requirement specification. We have named our methodology as Requirement analysis and UML diagram extraction (RAUE). General Terms: Textual Requirement Analysis by using NLP for generation of UML Diagram.
