Traditional requirements engineering methods typically involve interviews, observations, and questionnaires administered to stakeholders. Our hypothesis posits that this integral process can be significantly accelerated, and even enhanced, through strategic mining of app stores. App stores, such as Google Play and Apple Store, host millions of applications, making it likely to identify apps with features similar to the ones we intend to develop. These apps provide a wealth of information, including app descriptions, app reviews, and user interfaces. However, due to the vast quantity of apps, manual analysis of this information can be labor-intensive. To bridge this gap, our research aims to develop an approach called ReqRec for mining app stores, which will reduce the effort required by requirements engineers during the phase of requirements elicitation. To demonstrate the effectiveness of ReqRec, it will be applied to a case study involving the designing of a health monitoring application.
