Abstract: Online social networks (OSNs) have appeared, nowadays, as a powerful communication media in which users have the ability to share links, discuss and connect with each other. However, the easy-to-use interactive interfaces and the low barriers to publication characteristics have exposed information quality (IQ) problems (e.g., social spam, and information overload) [1], increasing the difficulty of obtaining accurate and relevant information. These characteristics have made OSNs vulnerable to various attacks by a particular kind of ill-intentioned users, so-called as social spammers, to post social spam contents.
