abstract = {In this paper we look at some details of the structure of the collaboration graph for the rough set researchers, discuss the entire graph as it exists at the present time and study its evolution over the past 25 years. Our approach is more experimental and statistical rather than theoretical. It seems that these data are interesting in their own right as a reflection of the way in which the rough set research gets done, apart from the mathematical questions raised about how to model and analyze social interactions.},
