| Challenge: | idioms have non-canonical meanings, but non-conventional meanings are contingent on other words . a recent study shows that idiomatic expressions are not homogeneous among idiomas . |
| Approach: | They propose to use a contingency relationship between words in an idiom and non-canonical meanings of words in the idiome. |
| Outcome: | a new study shows that idioms fall at the expected intersection of the two dimensions, but that the dimensions themselves are not correlated. |

Rethinking the Idiomaticity Decomposability Hypothesis: Evidence from Distributional Learning (2026.acl-long)
Copied to clipboard
| Challenge: | Decomposability is thought to predict syntactic flexibility, but is not attributed to distributional experience. |
| Approach: | They propose a model-internal measure of decomposability and relate it to human ratings, syntactic flexibility, and predictability while tracking idiom learning during pretraining. |
| Outcome: | The proposed model-internal measure correlates weakly with human judgments and shows a small but consistent negative relationship with syntactic flexibility. |

Paraphrases do not explain word analogies (2021.eacl-main)
Copied to clipboard
| Challenge: | Several attempts have been made to explain distributional word embeddings as linguistic regularities as directions. |
| Approach: | They propose to use an analogy to explain why linguistic regularities should hold in distributional word embeddings. |
| Outcome: | The proposed explanation does not hold empirically. |
Memorization or Reasoning? Exploring the Idiom Understanding of LLMs (2025.emnlp-main)
Copied to clipboard
| Challenge: | idioms have long posed a challenge due to their unique linguistic properties, which set them apart from other common expressions. |
| Approach: | They propose to use a large-scale dataset of idioms in six languages to evaluate LLMs' idiomatic processing ability. |
| Outcome: | The proposed model integrates contextual cues and reasoning to improve idiom understanding in LLMs, suggesting that their performance is influenced by memorization and reasoning. |

Crossing the Threshold: Idiomatic Machine Translation through Retrieval Augmentation and Loss Weighting (2023.emnlp-main)
Copied to clipboard
| Challenge: | idioms are common in everyday language, but often pose a challenge to translators because their meanings do not follow from the meanings of their parts. |
| Approach: | They propose to use retrieval-augmented models to increase the accuracy of a strong pretrained machine translation model on idiomatic sentences by up to 13%. |
| Outcome: | The proposed techniques improve the accuracy of a strong pretrained model on idiomatic sentences by up to 13% in absolute accuracy, and holds potential benefits for non-idiomatic phrases. |
