Real or fake?
Real or fake?
Real or fake?
Real or fake?
Types of misinformation
Towards computational verification
The Tweet Verification Assistant
A web-based service for marking an input tweet as “real” or “fake”
2012 first ideas and experiments (SocialSensor)
2013-2016 main research, development and validation (REVEAL)
2016-now incremental refinements and testing (InVID)
