NL Seminar-Exposing Brittleness in Reading Comprehension Systems
Thu, Nov 01, 2018 @ 11:00 AM - 12:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Robin Jia, Stanford University
Talk Title: Exposing Brittleness in Reading Comprehension Systems
Series: Natural Language Seminar
Abstract: Reading comprehension systems that answer questions over a context passage can often achieve high test accuracy, but they are frustratingly brittle: they often rely heavily on superficial cues, and therefore struggle on out-of-domain inputs. In this talk, I will describe our work on understanding and challenging these systems. First, I will show how to craft adversarial reading comprehension examples by adding irrelevant distracting text to the context passage. Next, I will present the newest version of the SQuAD dataset, SQuAD 2.0, which tests whether models can distinguish answerable questions from similar but unanswerable ones. Finally, I will share some observations from our recent attempts to use reading comprehension systems as a natural language interface for building other NLP systems.
Biography: Robin Jia is a fifth-year PhD student advised by Percy Liang at Stanford University. He is an NSF Graduate Fellow, and has received Outstanding Paper and Best Short Paper Awards from EMNLP and ACL, respectively.

NL Seminar-Taming the scientific literature: progress and challenges
Fri, Nov 09, 2018 @ 03:00 PM - 04:00 PM
Information Sciences Institute

Speaker: Waleed Ammar, AI2-Allen Inst.
Talk Title: Taming the scientific literature: progress and challenges
Series: Natural Language Seminar
Abstract: The magnitude and growth of the scientific literature can be overwhelming even for experienced researchers. Three years ago, the Allen Institute for Artificial Intelligence launched semanticscholar.org to understand and address the information needs of researchers. In this talk, I start by highlighting some of the lessons we learned from our 2M monthly actively users, and some of the key differences between academic and industrial research. Then, I describe three complementary directions for analyzing the scientific literature at scale. In the first direction, we extract meaningful structures such as entities, relationships and figures. In the second direction, we establish connections between different artifacts in the literature to facilitate navigation and enable complex querying capabilities. In the third direction, we try to address controversial questions in the literature by quantifying observable attributes at a large scale. I conclude with a short list of under-explored research opportunities with high potential in this domain.
Bio: Waleed Ammar is a senior research scientist at the Allen Institute for Artificial Intelligence where he leads the research efforts in the semantic scholar project. He is interested in developing NLP models with practical applications, especially in the scientific and medical domains and other data-constrained scenarios. Before pursuing his PhD at Carnegie Mellon University, Waleed an engineer at the machine translation group at MSR, a web developer at eSpace technologies, and a teaching assistant at Alexandria University. Waleed co-hosts the NLP highlights podcast with Matt Gardner.
