Probing Neural Language Models for Human Tacit Assumptions

no code implementations10 Apr 2020 Nathaniel Weir, Adam Poliak, Benjamin Van Durme

Our prompts are based on human responses in a psychological study of conceptual associations.

COD3S: Diverse Generation with Discrete Semantic Signatures

1 code implementation EMNLP 2020 Nathaniel Weir, João Sedoc, Benjamin Van Durme

We present COD3S, a novel method for generating semantically diverse sentences using neural sequence-to-sequence (seq2seq) models.

InFillmore: Frame-Guided Language Generation with Bidirectional Context

no code implementations Joint Conference on Lexical and Computational Semantics 2021 Jiefu Ou, Nathaniel Weir, Anton Belyy, Felix Yu, Benjamin Van Durme

We propose a structured extension to bidirectional-context conditional language generation, or "infilling," inspired by Frame Semantic theory (Fillmore, 1976).

NELLIE: A Neuro-Symbolic Inference Engine for Grounded, Compositional, and Explainable Reasoning

no code implementations16 Sep 2022 Nathaniel Weir, Peter Clark, Benjamin Van Durme

Our goal is a modern approach to answering questions via systematic reasoning where answers are supported by human interpretable proof trees grounded in an NL corpus of authoritative facts.

Defending Against Disinformation Attacks in Open-Domain Question Answering

no code implementations20 Dec 2022 Orion Weller, Aleem Khan, Nathaniel Weir, Dawn Lawrie, Benjamin Van Durme

Recent work in open-domain question answering (ODQA) has shown that adversarial poisoning of the search collection can cause large drops in accuracy for production systems.

"According to ...": Prompting Language Models Improves Quoting from Pre-Training Data

no code implementations22 May 2023 Orion Weller, Marc Marone, Nathaniel Weir, Dawn Lawrie, Daniel Khashabi, Benjamin Van Durme

Large Language Models (LLMs) may hallucinate and generate fake information, despite pre-training on factual data.

Reframing Tax Law Entailment as Analogical Reasoning

no code implementations12 Jan 2024 Xinrui Zou, Ming Zhang, Nathaniel Weir, Benjamin Van Durme, Nils Holzenberger

We re-frame statutory reasoning as an analogy task, where each instance of the analogy task involves a combination of two instances of statutory reasoning.

Enhancing Systematic Decompositional Natural Language Inference Using Informal Logic

no code implementations22 Feb 2024 Nathaniel Weir, Kate Sanders, Orion Weller, Shreya Sharma, Dongwei Jiang, Zhengping Jiang, Bhavana Dalvi Mishra, Oyvind Tafjord, Peter Jansen, Peter Clark, Benjamin Van Durme

Contemporary language models enable new opportunities for structured reasoning with text, such as the construction and evaluation of intuitive, proof-like textual entailment trees without relying on brittle formal logic.

TV-TREES: Multimodal Entailment Trees for Neuro-Symbolic Video Reasoning

no code implementations29 Feb 2024 Kate Sanders, Nathaniel Weir, Benjamin Van Durme

It is challenging to perform question-answering over complex, multimodal content such as television clips.
