  This paper presents a novel approach to generate a use case diagram by
analyzing the given user story using NLP and ML. Use case diagrams play a major
role in the designing phase of the SDLC. This proves the fact that automating
the use case diagram designing process would save a lot of time and effort.
Numerous manual and semi-automated tools have been developed previously. This
paper also discusses the need for use case diagrams and problems faced during
designing that. This paper is an attempt to solve those issues by generating
the use case diagram in a fully automatic manner.
