This paper has the intention of fostering synergy between the different research strands. It discusses the different research strands, details the crucial differences, and explores under which circumstances systems can be compared given publicly available data. To that end, we present results with the CoMiC-EN Content Assessment system (Meurers et al., 2011a) on the dataset published by<cite> Mohler et al. (2011)</cite> and outline what was necessary to perform this comparison.
