One of the challenges of requirements engineers is to understand domain issues and elicit requirements effectively. One of the possible strategies is to perform a manual inspection of similar projects to quickly gain leverage of domain concepts underlying the projects. However, this task is time-consuming and limited to the projects at hand. To ensure comprehensive elicitation using more widely available systems, we propose to use GitHub projects as information sources. To handle the large amount of data and facilitate access to suitable sources, we propose the creation of project profiles with useful attributes for requirements engineering, and thereby achieve a meaningful recommendation of projects. In this paper, we describe the GitHub assets to be mined, its implementation and the assessment of our approach by using a corpus of readmes related to Real Estate projects.
