摘要:

在社交媒体时代,谣言泛滥。对话结构提供了区分真实和虚假声明的有价值的线索。然而,现有的谣言检测方法要么局限于用户响应的严格关系,要么过于简化会话结构。在这项研究中,大大加强了用户意见的互动,同时减轻不相关的职位所带来的负面影响,我们首先表示的会话线程作为一个无向交互图。然后,我们提出了一个索赔引导的层次图注意力网络的谣言分类,提高了表示学习的响应帖子考虑到整个社会背景和出席的帖子,可以语义推断的目标索赔。在三个Twitter数据集上进行的大量实验表明,我们的谣言检测方法比最先进的方法具有更好的性能,并且在早期阶段检测谣言的能力更强。

英文摘要:

Rumors are rampant in the era of social media. Conversation structures provide valuable clues to differentiate between real and fake claims. However, existing rumor detection methods are either limited to the strict relation of user responses or oversimplify the conversation structure. In this study, to substantially reinforces the interaction of user opinions while alleviating the negative impact imposed by irrelevant posts, we first represent the conversation thread as an undirected interaction graph. We then present a Claim-guided Hierarchical Graph Attention Network for rumor classification, which enhances the representation learning for responsive posts considering the entire social contexts and attends over the posts that can semantically infer the target claim. Extensive experiments on three Twitter datasets demonstrate that our rumor detection method achieves much better performance than state-of-the-art methods and exhibits a superior capacity for detecting rumors at early stages.
