... paper, we formulate ex- tractive summarization as a two step learn- ing problem building a generative model for pattern discovery and a regression model for inference. We calculate scores for sentences ... approaches for MDS as presented in this paper. In this paper, we present a novel approach that formulates MDS as a prediction problem based on a two-step hybrid model: a genera...
