Presentation Title: Social Media Intelligence in practice: The NEREUS experimental platform


The increasing rise of social media has enabled users to share vast amount of user generated content in the online world. Such information could be easily gathered and processed in order to extract intelligence over its content. Nereus experimental framework serves as a tool able to extract intelligence from data collected from social media and draw conclusions over usage behavior. Such intrusive technologies could put in danger civil rights and thus should not be considered as a solely technical issue. The demo functionality presented, detects negative attitude towards law enforcement/ infringement from YouTube and is able to detect users characterized by delinquent behavior. Furthermore, it focuses on the detection of deviant behavior of minors, such as violent behavior or cyber bullying.
