arXiv:2605.22247v1 Announce Type: new Abstract: Idioms pose a fundamental challenge for language models, as their meaning cannot be inferred from surface form alone. Understanding such expressions, therefore, requires semantic abstraction beyond lexical overlap. We introduce IdioLink, a retrieval benchmark designed to test whether models can link idiomatic expressions to conceptually equivalent meanings expressed in literal or paraphrased forms. IdioLink comprises 10,700 documents and 2,140 queries, spanning 107 idioms with both literal and figurative uses. Each document and query is annotated
The continuous drive for more advanced and nuanced AI language understanding is pushing research into complex areas like idiomatic expressions, a known weakness for current models.
Improving AI's ability to grasp non-literal language is crucial for robust human-AI interaction, advanced content generation, and sophisticated semantic analysis across various applications.
This benchmark provides a new, challenging metric for evaluating language models, pushing them beyond surface-level understanding towards more human-like conceptual abstraction.

Introduction of a new, specialized benchmark to challenge language models on idiomatic understanding.
Improved performance of language models in grasping nuanced and non-literal human communication, leading to more natural interactions.
Reduced 'hallucinations' or misinterpretations by AI in complex text analysis, potentially enabling AI to handle more sensitive and context-dependent tasks.
