Systematic mapping of recommendation systems for requirements engineering

Recommendation systems provide users with up-to-date guidance on processes, artifacts or other project-relevant information. Recommendation systems for requirements engineering can be used to provide the right information, at the right time, to requirements engineers. In this paper, we use systematic mapping to provide an overview of recommendation systems for the requirements engineering process, their characteristics, and state of validation. The resulting maps are analyzed to provide conclusions and to identify the limitations of current studies, and future research areas. The results of the mapping are used to outline the motivation for our future work on a recommendation system that helps product managers decide on the assignment of requirements to subsequent releases while considering constraints such as time, effort, quality, and resources.
