Entailed Between the Lines: Incorporating Implication into NLI

ACL 2025long

Much of human communication depends on implication, conveying meaning beyond literal words to express a wider range of thoughts, intentions, and feelings. For models to better understand and facilitate human communication, they must be responsive to the text’s implicit meaning. We focus on Natural L…

On Reference (In-)Determinacy in Natural Language Inference

NAACL 2025findings

We revisit the reference determinacy (RD) assumption in the task of natural language inference (NLI), i.e., the premise and hypothesis are assumed to refer to the same context when human raters annotate a label. While RD is a practical assumption for constructing a new NLI dataset, we observe that c…

PropSegmEnt: A Large-Scale Corpus for Proposition-Level Segmentation and Entailment Recognition

ACL 2023findings

The widely studied task of Natural Language Inference (NLI) requires a system to recognize whether one piece of text is textually entailed by another, i.e. whether the entirety of its meaning can be inferred from the other. In current NLI datasets and models, textual entailment relations are typical…

Stretching Sentence-pair NLI Models to Reason over Long Documents and Clusters

EMNLP 2022finding

Natural Language Inference (NLI) has been extensively studied by the NLP community as a framework for estimating the semantic relation between sentence pairs. While early work identified certain biases in NLI models, recent advancements in modeling and datasets demonstrated promising performance.In…
