Webgreedy parsing algorithms, our discourse parser is very efﬁcient in practice. Second, by using two linear-chain CRFs to label a sequence of discourse constituents, we can incorporate contextual infor-mation in a more natural way, compared to us-ing traditional discriminative classiﬁers, such as SVMs. Speciﬁcally, in the Viterbi decoding of WebJun 23, 2016 · Input: A set U of integers, an integer k.
