... average continuity (AC) and edit distance (ED) as dissimi- larity metrics, with raw configuration for rank as- signment, and compare our multiple-rank model with the standard entity-based model ... as in Barzilay and Lapata (2008). In sentence ordering, we experiment with different approaches to assigning dissimilarity scores and ranks (Section 5.1.1). We also exper- iment with...
