Albeit the encouraging performance of our proposed approach on summarizing student responses, when applied to the DUC 2004 dataset (Hong et al., 2014) and evaluated using ROUGE we observe only comparable or marginal improvement over the ILP baseline.
notable systems include maximal marginal relevance (Carbonell and Goldstein, 1998), submodular functions (Lin and Bilmes, 2010), jointly extract and compress sentences (Zajic et al., 2007), optimize content selection and surface realization (Woodsend and Lapata, 2012), minimize reconstruction error (He et al., 2012), and dual decomposition (Almeida and Martins, 2013).
