A rapid increase in social media services in recent years has enabled people to share and seek information effectively. The openness, however, also makes them one of the most effective channels for misinformation. Given the speed of information diffusion on social networks coupled with the widespread propagation of fake news, phishing URLs, and inaccurate information, misinformation escalates quickly and can significantly impact users with undesirable consequences and wreak havoc instantaneously. In this tutorial, we define the concept of misinformation in social media, discuss the diffusion of misinformation in social media, and introduce challenges of its identification, intervention, and prevention methods in terms of misinformation and misinformation spreaders. We use examples to illustrate how to mine misinformation in social media, and also suggest available datasets as well as possible future work.
Target Audience: This tutorial will target researchers and practitioners who are interested in the area of misinformation mining and have basic knowledge of network analysis, data mining, and machine learning. It will be delivered at a college junior/senior level, and should be easily accessible to interested parties from both industry and academia.
Rationale:
Misinformation on social media platforms has become a major problem in recent years, which not only causes online public anxiety, but also triggers panic in physical world. In the 2013 World Economic Forum, misinformation spread has been voted as top ten globally significant issues1 malicious content would be pertinent and highly interesting the communities that regularly attend SBP. Over the last few years, many research efforts have been dedicated to finding misinformation and the spreaders on social media. The approaches that have been taken to address this problem span a broad spectrum of research including work from information diffusion, social network analysis, social media mining, and machine learning. As such, we expect that the interest in our tutorial will be comparable to the interest this topic has drawn from its respective fields. Misinformation modeling, diffusion, detection, and intervention are topics that will attract researchers of many disciplines from both academia and industry. The learning outcomes of the tutorial are:
