where, In fact, a state-of-the-art topic-segmentation model (Malioutov and Barzilay, 2006) (also called a cohesion model in this paper) can be naturally incorporated into the graph-partitioning alignment models that we have discussed.
we can augment the SeqCut, HieCut, and P rsCut models with the cohesion models to form three new models SeqCutTpc, HieCutTpc, and PrsCutTpc, respectively.
