1 code implementation Joint Conference on Lexical and Computational Semantics 2021 Ohad Rozen, Shmuel Amar, Vered Shwartz, Ido Dagan

Our approach facilitates learning generic inference patterns requiring relational knowledge (e. g. inferences related to hypernymy) during training, while injecting on-demand the relevant relational facts (e. g. pangolin is an animal) at test time.

Learning to Rationalize for Nonmonotonic Reasoning with Distant Supervision

no code implementations14 Dec 2020 Faeze Brahman, Vered Shwartz, Rachel Rudinger, Yejin Choi

In this paper, we investigate the extent to which neural models can reason about natural language rationales that explain model predictions, relying only on distant supervision with no additional annotation cost for human-written rationales.

Do Neural Language Models Overcome Reporting Bias?

1 code implementation COLING 2020 Vered Shwartz, Yejin Choi

Mining commonsense knowledge from corpora suffers from reporting bias, over-representing the rare at the expense of the trivial (Gordon and Van Durme, 2013).

Back to the Future: Unsupervised Backprop-based Decoding for Counterfactual and Abductive Commonsense Reasoning

1 code implementation EMNLP 2020 Lianhui Qin, Vered Shwartz, Peter West, Chandra Bhagavatula, Jena Hwang, Ronan Le Bras, Antoine Bosselut, Yejin Choi

Abductive and counterfactual reasoning, core abilities of everyday human cognition, require reasoning about what might have happened at time t, while conditioning on multiple contexts from the relative past and future.

Paragraph-level Commonsense Transformers with Recurrent Memory

1 code implementation4 Oct 2020 Saadia Gabriel, Chandra Bhagavatula, Vered Shwartz, Ronan Le Bras, Maxwell Forbes, Yejin Choi

Human understanding of narrative texts requires making commonsense inferences beyond what is stated explicitly in the text.

Commonsense Reasoning for Natural Language Processing
