Abstract
The emergence of the Internet as a ubiquitous technology has facilitated the
rapid evolution of social media as the leading virtual platform for
communication, content sharing, and information dissemination. In spite of
revolutionizing the way news used to be delivered to people, this technology
has also brought along with itself inevitable demerits. One such drawback is
the spread of rumors facilitated by social media platforms which may provoke
doubt and fear upon people. Therefore, the need to debunk rumors before their
wide spread has become essential all the more. Over the years, many studies
have been conducted to develop effective rumor verification systems. One aspect
of such studies focuses on rumor stance classification, which concerns the task
of utilizing users' viewpoints about a rumorous post to better predict the
veracity of a rumor. Relying on users' stances in rumor verification task has
gained great importance, for it has shown significant improvements in the model
performances. In this paper, we conduct a comprehensive literature review on
rumor stance classification in complex social networks. In particular, we
present a thorough description of the approaches and mark the top performances.
Moreover, we introduce multiple datasets available for this purpose and
highlight their limitations. Finally, some challenges and future directions are
discussed to stimulate further relevant research efforts.
