Idioms are integral components of language, playing a crucial role in understanding and processing linguistic expressions. Although extensive research has been conducted on the comprehension of idioms in the text domain, their interpretation in multi-modal spaces remains largely unexplored. In this work, we propose a multi-expert framework to investigate the transfer of idiomatic knowledge from the language to the vision modality. Through a series of experiments, we demonstrate that leveraging text-based representations of idioms can significantly enhance understanding of the visual space, bridging the gap between linguistic and visual semantics.

Sarcasm is a term that refers to the use of words to mock, irritate, or amuse someone. It is commonly used on social media. The metaphorical and creative nature of sarcasm presents a significant difficulty for sentiment analysis systems based on affective computing. The methodology and results of our team, UTNLP, in the SemEval-2022 shared task 6 on sarcasm detection are presented in this paper. We put different models, and data augmentation approaches to the test and report on which one works best. The tests begin with traditional machine learning models and progress to transformer-based and attention-based models. We employed data augmentation based on data mutation and data generation. Using RoBERTa and mutation-based data augmentation, our best approach achieved an F1-score of 0.38 in the competition’s evaluation phase. After the competition, we fixed our model’s flaws and achieved anF1-score of 0.414.
