LLMs struggle to translate proverbs into faithful narratives, study finds

Researchers have introduced a new task called "constrained semantic decompression" to evaluate how well large language models (LLMs) can transform abstract proverbs into detailed narratives. Using a dataset of Persian proverbs and stories, they found that current LLMs struggle to accurately capture the underlying moral and causal structures, exhibiting a "decompression gap." While models can generate fluent text, they often fail to faithfully represent the proverb's intended meaning, though techniques like explicit reasoning and iterative refinement show promise in improving performance.

    Constrained Semantic Decompression in LLMs through Persian Proverb-Conditioned Story Generation

    arXiv:2606.12599v1 Announce Type: new Abstract: Transforming a dense, abstract proverb into an engaging and morally faithful narrative requires deep cultural understanding and robust semantic grounding. We frame this problem as a \emph{constrained semantic decompression} task and…
