• Title: Sarcasm Detection in a Less-Resourced Language
• Authors: Lazar Đoković, Marko Robnik-Šikonja,
• Abstract summary: We build a sarcasm detection dataset for a less-resourced language, such as Slovenian. We leverage two modern techniques: a machine translation specific medium-size transformer model, and a very large generative language model. The results show that larger models generally outperform smaller ones and that ensembling can slightly improve sarcasm detection performance.

• Abstract: The sarcasm detection task in natural language processing tries to classify whether an utterance is sarcastic or not. It is related to sentiment analysis since it often inverts surface sentiment. Because sarcastic sentences are highly dependent on context, and they are often accompanied by various non-verbal cues, the task is challenging. Most of related work focuses on high-resourced languages like English. To build a sarcasm detection dataset for a less-resourced language, such as Slovenian, we leverage two modern techniques: a machine translation specific medium-size transformer model, and a very large generative language model. We explore the viability of translated datasets and how the size of a pretrained transformer affects its ability to detect sarcasm. We train ensembles of detection models and evaluate models' performance. The results show that larger models generally outperform smaller ones and that ensembling can slightly improve sarcasm detection performance. Our best ensemble approach achieves an $\text{F}_1$-score of 0.765 which is close to annotators' agreement in the source language.

  We show that multilingual models suffer from significant gender biases just as monolingual models do. We propose a novel benchmark, MAGBIG, intended to foster research on gender bias in multilingual models. Our results show that not only do models exhibit strong gender biases but they also behave differently across languages.

  Previous work has shown that the representations output by contextual language models are more anisotropic than static type embeddings. This seems to be true for both monolingual and multilingual models, although much less work has been done on the multilingual context. We investigate outlier dimensions and their relationship to anisotropy in multiple pre-trained multilingual language models.

  Sarcasm is a linguistic phenomenon indicating a discrepancy between literal meanings and implied intentions. Most existing techniques only modeled the atomic-level inconsistencies between the text input and its accompanying image. We propose a novel hierarchical framework for sarcasm detection by exploring both the atomic-level congruity based on multi-head cross attention mechanism and the composition-level congruity based on graph neural networks.

  Sarcasm is the use of words usually used to either mock or annoy someone, or for humorous purposes. We propose a contextual model for sarcasm identification in twitter using RoBERTa and augmenting the dataset. We achieve performance gain by 3.2% in the iSarcasm dataset when using data augmentation to increase 20% of data labeled as sarcastic.
