Automatic Transformation of User Stories into UML Use Case Diagrams using NLP Techniques.

Agile methods in general and the Scrum method in particular are gaining more and more trust from the software developer community. When it comes to writing a functional requirement, user stories become more and more usable by the community. Furthermore, a considerable effort has already been made by the community in relation to the use of the use case tool when drafting requirements and in terms of model transformation. We have reached a certain stage of maturity at this level. The idea of our paper is to profit from these richness and to invest it in the drafting of user stories. In this paper, we propose a process of transforming user stories into use cases and we will be able to benefit from all the work done in the transformation of the models according to the MDA approach. To do this, we used natural language processing (NLP) techniques, by applying TreeTagger parser. Our work was validated by a case study where we were able to obtain very positive precisions between 87% and 98%. [ABSTRACT FROM AUTHOR]
