TITLE: Identification of Unreliable Accounts in Social Networks - current approaches and real-world scenarios
PRESENTER: Nuno Guimaraes
University of Porto, Portugal
ABSTRACT:

The rise of social networks revolutionized the way people create, share, and consume content. Consequently, these have become a platform where the quantity of information is higher, travels quickly, and reaches a broader audience compared with more traditional mediums (such as television and radio). Social networks' popularity and lack of moderation allowed unreliable information to proliferate and caused a significant impact in the political, economic, and social domains. This talk will be two-folded. In the first part, we attempt to summarize the principal findings on the topic, highlighting the main research efforts from the past few years to analyze and automatically identify unreliable content and accounts. In the second part, we will focus on some limitations of the current approaches in identifying unreliable accounts. In addition, we will present some solutions (knowledge-based and classification-based) that try to complement the current literature with a more pragmatic approach capable of coping with real-world situations.
