... Sentence Relation Labeling. In a thread containing N sentences, we would have a 2D CRF containing N 2 nodes in a N × N grid. Exact inference in such a graph is intractable. In this paper we use ... consum- ing. Most prior work focused on extracting only question answering sentences from user conversations. In this paper, we introduce the task of sentence dependency tagging. Findin...
