Multimodal Sarcasm Target Identification in Tweets (2022.acl-long)
Copied to clipboard
| Challenge: | Existing methods to detect sarcasm target with text lacking context are not sufficient and complete. |
| Approach: | They propose a multi-modal sarcasm target identification task that performs both textual and visual detection. |
| Outcome: | The proposed model can perform textual target labeling and visual target detection. |
RIVA: A Pre-trained Tweet Multimodal Model Based on Text-image Relation for Multimodal NER (2020.coling-main)
Copied to clipboard
| Challenge: | Named entity recognition (MNER) for tweets is a key task of many applications. |
| Approach: | They propose a pre-trained multimodal named entity recognition model based on Relationship Inference and Visual Attention (RIVA) for tweets. |
| Outcome: | The proposed model improves on the multimodal named entity recognition (MNER) task on tweets with the aid of visual clues. |
