Dependency-based Compositional Semantics (DCS) is a framework of natural language semantics with easy-to-process structures as well as strict semantics. In this paper, we equip the DCS framework with logical inference, by defining abstract denotations as an abstraction of the computing process of denotations in original DCS. An inference engine is built to(More)
The baiji, or Yangtze River dolphin (Lipotes vexillifer), is a flagship species for the conservation of aquatic animals and ecosystems in the Yangtze River of China; however, this species has now been recognized as functionally extinct. Here we report a high-quality draft genome and three re-sequenced genomes of L. vexillifer using Illumina short-read(More)
We propose a novel neural network model for machine reading, DER Network, which explicitly implements a reader building dynamic meaning representations for entities by gathering and accumulating information around the entities as it reads a document. Evaluated on a recent large scale dataset (Her-mann et al., 2015), our model exhibits better results than(More)
This paper describes our question answering system for Entrance Exams, which is a pilot task of the Question Answering for Machine Reading Evaluation at Conference and Labs of the Evaluation Forum (CLEF) 2013. We conducted experiments in which participants were provided with documents and multiple-choice questions. Their goals was to select one answer or(More)
The BnO team participated in the Recognizing Inference in TExt (RITE) subtask of the NTCIR-10 Workshop [5]. This paper describes our textual entailment recognition system with experimental results for the five Japanes subtasks: BC, MC, EXAMBC, EXAM-SEARCH, and UnitTest. Our appoach includes a shallow method based on word overlap features and named entity(More)
For textual entailment recognition systems, it is often important to correctly handle Generalized quantifiers (GQ). In this paper, we explore ways of encoding GQs in a recent framework of Dependency-based Composi-tional Semantics, especially aiming to correctly handle linguistic knowledge like hy-ponymy when GQs are involved. We use both the selection(More)
