Use case diagram is useful in software application development in order to capture functional requirements and to manage robust system complexity. We present, in this paper, a critical review of works concerned to the use case diagram obtaining from stakeholder discourse representations, in the form of natural or controlled language discourses. We conclude, from this review, that such representations are difficult to obtain in the previous stages of software development, when the analyst must subjectively influence the process, and when the process is still incomplete, due to the lack of special actor-use-case relationship identification.
