This challenge aims to identify a piece of information shared on social network sites (SNSs), is reliable or unreliable. With the blazing-fast spurt of SNSs, e.g., Facebook, Zalo, or Lotus, there are approximately 65 million Vietnamese users on board with the annual growth of 2.7 million in the recent year, as reported by the Digital 2020 [6]. SNSs become essential means for users to not only connect friends but also freely create, share diverse information [2, 5], i.e., news. Within freedom, a number of users tend to spread unreliable information for their personal purposes affecting the online society. Detecting whether news spreading in SNSs is reliable or unreliable has gained significant attention recently [1, 3, 4]. Therefore, this shared task targets identifying shared information in Vietnamese SNSs. It provides an opportunity for participants who are interested in the problem, to contribute their knowledge to improve the online society for social good.
