LLM metaphor processing probed for semantic alignment and syntactic sensitivity

A new research paper explores how large language models (LLMs) process metaphors, examining semantic alignment, lexical invariance, and syntactic sensitivity. The study found that while LLMs perform well on metaphor tasks, their interpretations can show semantic drift and are sensitive to syntactic changes. The research suggests that strong performance on metaphor benchmarks may not always indicate a deep, integrated semantic understanding. AI

    Probing Semantic Alignment, Lexical Invariance, and Syntactic Influence in LLM Metaphor Processing

    arXiv:2510.04120v2 Announce Type: replace-cross Abstract: Large language models (LLMs) achieve strong performance on metaphor detection and interpretation tasks, yet it remains unclear what such behavioral success reveals about metaphor processing. We present a diagnostic analysi…
