REG is related to content selection, which has been studied for generating text from databases (Konstas and Lapata, 2012), event streams (Chen et al., 2010), images (Berg et al., 2012;Zitnick and Parikh, 2013), and text (Barzilay and Lapata, 2005;Carenini et al., 2006).
most approaches to this problem output bags of concepts, while we construct full logical expressions, allowing our approach to capture complex relations between attributes.
