ATOMIC: An Atlas of Machine Commonsense for If-Then Reasoning

Maarten SapRonan Le BrasEmily AllawayYejin Choi
2019
AAAI

We present ATOMIC, an atlas of everyday commonsense reasoning, organized through 877k textual descriptions of inferential knowledge. Compared to existing resources that center around taxonomic… 

QuaRel: A Dataset and Models for Answering Questions about Qualitative Relationships

Oyvind TafjordPeter ClarkMatt GardnerAshish Sabharwal
2019
AAAI

Many natural language questions require recognizing and reasoning with qualitative relationships (e.g., in science, economics, and medicine), but are challenging to answer with corpus-based methods.… 

Declarative Question Answering over Knowledge Bases containing Natural Language Text with Answer Set Programming

Arindam MitraPeter ClarkOyvind TafjordChitta Baral
2019
AAAI

While in recent years machine learning (ML) based approaches have been the popular approach in developing end-to-end question answering systems, such systems often struggle when additional knowledge… 

QASC: A Dataset for Question Answering via Sentence Composition

Tushar KhotPeter ClarkMichal GuerquinAshish Sabharwal
2019
AAAI

Composing knowledge from multiple pieces of texts is a key challenge in multi-hop question answering. We present a multi-hop reasoning dataset, Question Answering via Sentence Composition (QASC),… 

On the Capabilities and Limitations of Reasoning for Natural Language Understanding

Daniel KhashabiErfan Sadeqi AzerTushar KhotDan Roth
2019
arXiv

Recent systems for natural language understanding are strong at overcoming linguistic variability for lookup style reasoning. Yet, their accuracy drops dramatically as the number of reasoning steps… 

Expanding Holographic Embeddings for Knowledge Completion

Yexiang XueYang YuanZhitian XuAshish Sabharwal
2018
NeurIPS

Neural models operating over structured spaces such as knowledge graphs require a continuous embedding of the discrete elements of this space (such as entities) as well as the relationships between… 

Memory Augmented Policy Optimization for Program Synthesis and Semantic Parsing

Chen LiangMohammad NorouziJonathan BerantNi Lao
2018
NeurIPS

This paper presents Memory Augmented Policy Optimization (MAPO): a novel policy optimization formulation that incorporates a memory buffer of promising trajectories to reduce the variance of policy… 

Mapping Images to Scene Graphs with Permutation-Invariant Structured Prediction

Roei HerzigMoshiko RabohGal ChechikAmir Globerson
2018
NeurIPS

Machine understanding of complex images is a key goal of artificial intelligence. One challenge underlying this task is that visual scenes contain multiple inter-related objects, and that global… 

EARLY FUSION for Goal Directed Robotic Vision

Aaron WalsmanYonatan BiskSaadia GabrielD. Fox
2018
IROS

Building perceptual systems for robotics which perform well under tight computational budgets requires novel architectures which rethink the traditional computer vision pipeline. Modern vision… 

Bridging Knowledge Gaps in Neural Entailment via Symbolic Models

Dongyeop KangTushar KhotAshish Sabharwal and Peter Clark
2018
EMNLP

Most textual entailment models focus on lexical gaps between the premise text and the hypothesis, but rarely on knowledge gaps. We focus on filling these knowledge gaps in the Science Entailment…
