Quantifying the narrative flow of imagined versus autobiographical stories.

Maarten SapA. JafarpourYejin ChoiE. Horvitz
2022
Proceedings of the National Academy of Sciences of the United States of America

Lifelong experiences and learned knowledge lead to shared expectations about how common situations tend to unfold. Such knowledge of narrative event flow enables people to weave together a story.… 

Generating Sequences by Learning to Self-Correct

S. WelleckXiming LuPeter WestYejin Choi
2022
arXiv

Sequence generation applications require satisfying semantic constraints, such as ensuring that programs are correct, using certain keywords, or avoiding undesir-able content. Language models,… 

Learning to Decompose: Hypothetical Question Decomposition Based on Comparable Texts

Ben ZhouKyle RichardsonXiaodong YuDan Roth
2022
EMNLP

Explicit decomposition modeling, which involves breaking down complex tasks into more straightforward and often more interpretable sub-tasks, has long been a central theme in developing robust and… 

Threddy: An Interactive System for Personalized Thread-based Exploration and Organization of Scientific Literature

Hyeonsu B. KangJoseph Chee ChangYongsung KimAniket Kittur
2022
UIST

Reviewing the literature to understand relevant threads of past work is a critical part of research and vehicle for learning. However, as the scientific literature grows the challenges for users to… 

FeedLens: Polymorphic Lenses for Personalizing Exploratory Search over Knowledge Graphs

While research on scientific claim verification has led to the development of powerful systems that appear to approach human performance, these approaches have yet to be tested in a realistic… 

Referee: Reference-Free Sentence Summarization with Sharper Controllability through Symbolic Knowledge Distillation

Melanie SclarPeter WestSachin KumarYejin Choi
2022
Conference on Empirical Methods in Natural Language Processing

We present Referee, a novel framework for sentence summarization that can be trained reference-free (i.e., requiring no gold summaries for supervision), while allowing direct control for compression…
