Automated support for combinational creativity in requirements engineering

Requirements engineering (RE), framed as a creative problem solving process, plays a key role in innovating more useful and novel requirements and improving a software system's sustainability. Existing approaches, such as creativity workshops and feature mining from web services, facilitate creativity by exploring a search space of partial and complete possibilities of requirements. To further advance the literature, we support creativity from a combinational perspective, i.e., making unfamiliar connections between familiar possibilities of requirements. In particular, we propose a novel framework that extracts familiar ideas from the requirements and stakeholders' comments using topic modeling and applies part-of-speech tagging to obtain unfamiliar idea combinations. We apply our framework on two large open source software systems and further report a human subject evaluation. The results show that our framework complements existing approaches by generating original and relevant requirements in an automated manner.
