For the experiments presented in this paper, the baseline models were implemented based on<cite> [Lavie et al. 2008]</cite> and [Tinsley et al. 2007 ] mainly because they do not require rich resources such as [Marecek et al. 2008] neither use manually created composition rules as [Menezes and Richardson 2001] and [Groves et al. 2004 ].
