Challenge: Figures of speech and figures of language are used in everyday communication . however, this imaginative use of words requires a solid understanding of semantics and real-world knowledge.
Approach: They exploit probing tasks to analyse how NLMs recognise figurative language . they find out which layers have a better comprehension of figurativ language based on pre-training data.
Outcome: The proposed model can recognise hyperboles, metaphors, oxymorons and pleonasms . data show which layers have a better comprehension of figurative language .

Challenge: In this paper, we show that neural language models with different initialization, architecture, and training data acquire linguistic phenomena in a similar order, despite their different end performance.
Approach: They propose to use mutual inductive bias to study linguistic representations implicit in NLMs.

Challenge: Recent years have witnessed a growing interest in investigating what Transformer-based language models (TLMs) actually learn from training data.
Approach: They propose to use a black-box TLM and two intrinsically transparent white-box models to investigate the performance of figurative language models on sarcasm, similes, idioms, and metaphors.

A Distributional Perspective on Word Learning in Neural Language Models (2025.naacl-long)

Challenge: Language models are increasingly being studied as models of human language learners.
Approach: They propose a distributional approach to word learning that captures distributional knowledge and gradient preferences for the word’s appropriateness.
Outcome: The proposed signatures capture knowledge of where the target word can and cannot occur as well as gradient preferences about the word’s appropriateness.
It’s not Rocket Science: Interpreting Figurative Language in Narratives (2022.tacl-1)

Challenge: Existing text representations by design rely on compositionality, while figurative language is often non-compositional.
Approach: They propose to use a pre-trained language model to interpret figurative language types to adopt human strategies for interpreting figurativ language types: inferring meaning from context and relying on constituent words’ literal meanings.
Outcome: The proposed models perform significantly worse than humans on discriminative and generative tasks, bridging the gap from human performance.
Multi-lingual and Multi-cultural Figurative Language Understanding (2023.findings-acl)

Challenge: Figures permeate human communication, but are understudied in NLP.
Approach: They create a figurative language inference dataset for seven languages associated with a variety of cultures, using cultural and regional concepts for figurativ expressions.
Outcome: The results show that the most common figurative expressions are found in Hindi, Indonesian, Javanese, Kannada, Sundanese, Swahili and Yoruba.

Challenge: Figurative language understanding is a recognizing textual entailment task, but lacks data for figurative language.
Approach: They propose to use a dataset to analyze figurative NLI instances with explanations to improve models' performance.
Outcome: The proposed dataset can scale up models even for figurative language using human annotations.

Challenge: Figures are based on the use of words in a way that deviates from their conventional order and meaning.
Approach: They propose to use a figurative language model to interpret embodied metaphors by using larger language models that conceptualise embodies the action of the metaphorical sentence.
Outcome: The proposed model enables interpretation of figurative language when the action of the metaphorical sentence is more embodied.

Challenge: Existing RTE models struggle to capture figurative language, despite its ubiquity, it remains a bottleneck in automatic text understanding.
Approach: They propose to frame five existing figurative language datasets into over 12,500 RTE examples.
Outcome: The proposed models struggle to perform pragmatic inference and reasoning about world knowledge.
Testing the Ability of Language Models to Interpret Figurative Language (2022.naacl-main)

Copied to clipboard

Challenge: Existing work on figurative language has not been done on literal language models.
Approach: They propose a Winograd-style task to evaluate figurative phrases with divergent meanings by interpreting paired figurativ phrases with a human input.
Outcome: The proposed task outperforms state-of-the-art models on a nonliteral language understanding task in zero-shot settings.
