“…Traditionally, this was tackled using human designed features and classical machine learning techniques. This included heuristics with Markov models (Barzilay and Lee, 2004;Bollegala et al, 2005;Ji and Pulman, 2006), K-means clustering (Ji and Nie, 2008;Zhang, 2011), support vector machines (Bollegala et al, 2006;Nahnsen, 2009;Peng et al, 2009;Yanase et al, 2015) and others like latent semantic analysis (Zhang et al, 2010) and conditional random fields (Gella and Duong Thanh, 2012). We also note the representation of sentence ordering as a graph in many past works as well (Elsner and Charniak, 2011;Li et al, 2011;Guinaudeau and Strube, 2013).…”
