  • Semi-Markov Phrase-based Monolingual Alignment

    Xuchen Yao, Benjamin Van Durme, Chris Callision-Burch, and Peter ClarkEMNLP2013 We introduce a novel discriminative model for phrase-based monolingual alignment using a semi-Markov CRF. Our model achieves stateof-the-art alignment accuracy on two phrasebased alignment datasets (RTE and paraphrase), while doing significantly better than… more
  • Constructing a Textual KB from a Biology TextBook

    Peter Clark, Phil Harrison, Niranjan Balasubramanian, and Oren EtzioniNAACL-HLT • AKBC Workshop2012 As part of our work on building a "knowledgeable textbook" about biology, we are developing a textual question-answering (QA) system that can answer certain classes of biology questions posed by users. In support of that, we are building a "textual KB" - an… more
