PARADIGMA: Uma Ferramenta de Apoio à Elicitação e Modelagem de Requisitos Baseada em Processamento de Linguagem Natural

The requirements engineers use several techniques to assist them on the elicitation, analysis, specification, validation and requirements management process, but the number of those tools in this segment is still reduced. The requirements are the base for the software development, which, most of time is described in natural language. In this paper a tool called PARADIGMA is presented, it was developed to assist the requirements engineers to identify in a easier way classes, attributes, operations and relationships from the described requirements in natural language, and using the Natural Language Processing (more specifically the morphosyntatics taggers), generating a conceptual classes model of UML (Unified Modeling Language). Besides the mentioned characteristics above, the tool uses the concept of linguistic standards that facilitate the creation of diagrams closer to those created by human. The experimentation of the tool was made by professionals and professors who act in the area of Requirements Engineering. On the basis of the results, we come to the conclusion of the relevance of the tool PARADIGMA in the context of the Requirements Engineering.
