Allusion recognition—a task demanding contextual activation of cultural knowledge—serves as a critical test of LLMs’ ability to deploy stored information in open-ended, figurative settings. We introduce a framework for evaluating Persian literary allusions through (1) classical poetry annotations and (2) LLM-generated texts incorporating allusions in novel contexts. By combining knowledge assessments, multiple-choice tasks, and open-ended recognition, we analyze whether failures stem from knowledge gaps or activation challenges. Evaluations across eleven LLMs highlight a notable observation: models exhibit strong foundational knowledge and high multiple-choice accuracy, yet performance drops substantially in open-ended tasks, especially for indirect references. Reasoning-optimized models generalize better to novel contexts, whereas distilled models show marked degradation in cultural reasoning. The gap underscores that LLMs’ limitations arise not from missing knowledge but from difficulties in spontaneously activating cultural references without explicit cues. We propose allusion recognition as a benchmark for contextual knowledge deployment, highlighting the need for training paradigms that bridge factual recall and culturally grounded reasoning.

ImageArg is a shared task at the 10th ArgMining Workshop at EMNLP 2023. It leverages the ImageArg dataset to advance multimodal persuasiveness techniques. This challenge comprises two distinct subtasks: 1) Argumentative Stance (AS) Classification: Assessing whether a given tweet adopts an argumentative stance. 2) Image Persuasiveness (IP) Classification: Determining if the tweet image enhances the persuasive quality of the tweet. We conducted various experiments on both subtasks and ranked sixth out of the nine participating teams.
