• Abstract: We propose an unsupervised approach for sarcasm generation based on a non-sarcastic input sentence. Our method employs a retrieve-and-edit framework to instantiate two major characteristics of sarcasm: reversal of valence and semantic incongruity with the context which could include shared commonsense or world knowledge between the speaker and the listener. While prior works on sarcasm generation predominantly focus on context incongruity, we show that combining valence reversal and semantic incongruity based on the commonsense knowledge generates sarcasm of higher quality. Human evaluation shows that our system generates sarcasm better than human annotators 34% of the time, and better than a reinforced hybrid baseline 90% of the time.

  We analyze the prosodic features within utterances and key phrases belonging to three distinct sarcasm categories. Results show that in phrases where the sarcastic meaning is salient from the semantics, the prosodic cues are less relevant than when the sarcastic meaning is not evident from the semantics.

  We propose a novel sEntiment-enhanceD Graph-based multimodal sarcasm Explanation framework, named EDGE. In particular, we first propose a lexicon-guided utterance sentiment inference module, where a utterance sentiment refinement strategy is devised. We then develop a module named Joint Cross Attention-based Sentiment Inference (JCA-SI) by extending the multimodal sentiment analysis model JCA to derive the joint sentiment label for each video-audio clip.

  We study a new problem of cross-modal sarcasm generation (CMSG), i.e., generating a sarcastic description for a given image. CMSG is challenging as models need to satisfy the characteristics of sarcasm, as well as the correlation between different modalities. We propose an Extraction-Generation-Ranking based Modular method (EGRM) for cross-model sarcasm generation.

  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 employs ambivalence, where one says something positive but actually means negative, and vice versa. We show up the essence of sarcastic text is that the literal sentiment is opposite to the deep sentiment. We propose a Dual-Channel Framework by modeling both literal and deep sentiments to recognize the sentiment conflict.

We demonstrate that modeling sarcasm improves the argumentative relation classification task (agree/disagree/none) in all setups.
