... naturally translated into a ranking problem: to reorder, we determine a “rank” for each child, then the children are sorted according to their “ranks”. As it is often impractical to directly assign a ... Model Training To learn ranking function in Equation (1), we need to determine the feature set θ and learn weight vector w from reorder examples. In this section, we first describe h...

... differences hold to a lesser degree when a partial dictionary is provided. With MLHMM, different tokens of the same word type are usually assigned to the same cluster, but types are assigned to clusters ... We would also like to thank Noah Smith for providing us with his data sets. Eisner, 2005). Nearly all of these approaches have one aspect in common: the goal of learning is to id...

It makes a transition to state (q 1 ) when it encounters ... is to enable the quality and nature of discussions that occur within an on-line discussion board to be communicated in a summary to a potential new- comer or group moderators.

... first step, 8 anno- tators were asked to select words to be removed to compress the sentences. In the second step, 6 an- notators (different from the first step) were asked to pick the best one ... and reranking is able to yield additional gain, espe- cially when training is performed to take into account multiple references. 1 Introduction Sentence compression aims to preserve th...

This approach ... alternative to these tree trimming approaches, sequence-oriented approaches have been proposed (McDonald, 2006; Nomoto, 2007; Hori and Furui, 2003; Clarke and Lapata, 2006).
