Generating Requirements Analysis Models from Textual Requirements

Use case modeling is a commonly used technique to describe functional requirements in requirements engineering. Typically, use cases are captured from textual requirements documents describing the functionalities the system should meet. Requirements elicitation, analysis and modeling is a time consuming and error-prone activity, which it is not usually supported by automated tools. This paper tackles this problem by taking free-form textual requirements and offering a semi-automatic process for generation of domain models, such as use cases. Our goal is twofold: (i) reduce the time spent to produce requirements artifacts; and (ii) enable future application of model-driven engineering techniques to maintain traceability information and consistency between textual and requirements visual models artifacts.
