  • Iconary: A Pictionary-Based Game for Testing Multimodal Communication with Drawings and Text

    Christopher Clark, Jordi Salvador, Dustin Schwenk, Derrick Bonafilia, Mark Yatskar, Eric Kolve, Alvaro Herrasti, Jonghyun Choi, Sachin Mehta, Sam Skjonsberg, Carissa Schoenick, A. Sarnat, Hannaneh Hajishirzi, Aniruddha Kembhavi, Oren Etzioni, Ali FarhadiarXiv2021 Communicating with humans is challenging for AIs because it requires a shared understanding of the world, complex semantics (e.g., metaphors or analogies), and at times multimodal gestures (e.g., pointing with a finger, or an arrow in a diagram). We…
  • Specializing Multilingual Language Models: An Empirical Study

    Ethan C. Chau, Noah A. SmithEMNLP • Workshop on Multilingual Representation Learning2021
    Best Paper Honorable Mention
    Pretrained multilingual language models have become a common tool in transferring NLP capabilities to low-resource languages, often with adaptations. In this work, we study the performance, extensibility, and interaction of two such adaptations: vocabulary…
  • Towards Personalized Descriptions of Scientific Concepts

    Sonia K. Murthy, Daniel King, Tom Hope, Daniel S. Weld, Doug DowneyEMNLP 2021 • WiNLP2021 A single scientific concept can be described in many different ways, and the most informative description depends on the audience. In this paper, we propose generating personalized scientific concept descriptions that are tailored to the user’s expertise and…
  • Achieving Model Robustness through Discrete Adversarial Training

    Maor Ivgi, Jonathan BerantEMNLP2021 Discrete adversarial attacks are symbolic perturbations to a language input that preserve the output label but lead to a prediction error. While such attacks have been extensively explored for the purpose of evaluating model robustness, their utility for…
  • Back to Square One: Bias Detection, Training and Commonsense Disentanglement in the Winograd Schema

    Yanai Elazar, Hongming Zhang, Yoav Goldberg, Dan RothEMNLP2021 The Winograd Schema (WS) has been proposed as a test for measuring commonsense capabilities of models. Recently, pre-trained language model-based approaches have boosted performance on some WS benchmarks but the source of improvement is still not clear. We…
  • BeliefBank: Adding Memory to a Pre-Trained Language Model for a Systematic Notion of Belief

    Nora Kassner, Oyvind Tafjord, H. Schutze, P. ClarkEMNLP2021 Although pretrained language models (PTLMs) have been shown to contain significant amounts of world knowledge, they can still produce inconsistent answers to questions when probed, even after using specialized training techniques to reduce inconsistency. As a…
  • CDLM: Cross-Document Language Modeling

    Avi Caciularu, Arman Cohan, Iz Beltagy, Matthew E. Peters, Arie Cattan, Ido DaganFindings of EMNLP2021 We introduce a new pretraining approach for language models that are geared to support multi-document NLP tasks. Our crossdocument language model (CD-LM) improves masked language modeling for these tasks with two key ideas. First, we pretrain with multiple…
  • Contrastive Explanations for Model Interpretability

    Alon Jacovi, Swabha Swayamdipta, Shauli Ravfogel, Yanai Elazar, Yejin Choi, Yoav GoldbergEMNLP2021 Contrastive explanations clarify why an event occurred in contrast to another. They are more inherently intuitive to humans to both produce and comprehend. We propose a methodology to produce contrastive explanations for classification models by modifying the…
  • Documenting Large Webtext Corpora: A Case Study on the Colossal Clean Crawled Corpus

    Jesse Dodge, Maarten Sap, Ana Marasović, William Agnew, Gabriel Ilharco, Dirk Groeneveld, Matt GardnerEMNLP2021 As language models are trained on ever more text, researchers are turning to some of the largest corpora available. Unlike most other types of datasets in NLP, large unlabeled text corpora are often presented with minimal documentation, and best practices for…
  • Explaining Answers with Entailment Trees

    Bhavana Dalvi, Peter A. Jansen, Oyvind Tafjord, Zhengnan Xie, Hannah Smith, Leighanna Pipatanangkura, Peter ClarkEMNLP2021 Our goal, in the context of open-domain textual question-answering (QA), is to explain answers by not just listing supporting textual evidence (“rationales”), but also showing how such evidence leads to the answer in a systematic way. If this could be done…
