Affection Enhanced Relational Graph Attention Network for Sarcasm Detection
TL;DR: This work proposes an Affection Enhanced Relational Graph Attention network (ARGAT) by jointly considering the affective information and the dependency information and shows that the proposed approach outperforms state-of-the-art sarcasm detection methods.
Journal ArticleDOI
Jointly Learning Sentimental Clues and Context Incongruity for Sarcasm Detection
TL;DR: Experimental results on datasets show that the model proposed yields better performance for the sarcasm detection task with the help of sentiment clues and incongruity information.
Proceedings ArticleDOI
Sentiment-Aware Fake News Detection on Social Media with Hypergraph Attention Networks
TL;DR: Wang et al. as discussed by the authors proposed a Sentiment-Aware Hypergraph Attention Network (SA-HyperGAT) for fake news detection, which constructs two hypergraphs with distinct types of nodes and hyperedges to utilize structural information of news contents and sentimental information of user comments.
Journal ArticleDOI
Sentiment-Aware Emoji Insertion Via Sequence Tagging
TL;DR: This article focuses on the sentiment-aware emoji insertion task, which predicts multiple emojis and their positions in a sentence conditioned on the plain texts and sentiment polarities, and forms the insertion process as a sequence tagging task and applies a BERT-BiLSTM-CRF model.
Proceedings ArticleDOI
Commonsense-Aware Sarcasm Detection with Heterogeneous Graph Attention Network
TL;DR: Wang et al. as discussed by the authors propose a commonsense-aware model with a heterogeneous graph attention network that leverages commonsense knowledge, enabling it to better understand implied sentiment behind the literal meaning.
