摘 要:The task of cross-target stance detection faces significant challenges due to the lack of additional background information in emerging knowledge domains and the colloquial nature of language *** stance detection methods often struggle with understanding limited context and have insufficient generalization across diverse sentiments and semantic *** paper focuses on effectively mining and utilizing sentimentsemantics knowledge for stance knowledge transfer and proposes a sentiment-aware hierarchical attention network(SentiHAN)for cross-target stance *** introduces an improved hierarchical attention network designed to maximize the use of high-level representations of targets and texts at various fine-grain *** model integrates phrase-level combinatorial sentiment knowledge to effectively bridge the knowledge gap between known and unknown *** doing so,it enables a comprehensive understanding of stance representations for unknown targets across different sentiments and semantic *** model’s ability to leverage sentimentsemantics knowledge enhances its performance in detecting stances that may not be directly observable from the immediate *** experimental results indicate that SentiHAN significantly outperforms existing benchmark methods in terms of both accuracy and ***,the paper employs ablation studies and visualization techniques to explore the intricate relationship between sentiment and *** analyses further confirm the effectiveness of sentence-level combinatorial sentiment knowledge in improving stance detection capabilities.
