The advent of online social networks (OSNs) paired with the ubiquitous proliferation of smartphones have enabled social sensing systems. In the last few years, the aptitude of humans to spontaneously collect and timely share context information has been...

A novel approach to modeling online user behavior extracts and analyzes digital DNA-inspired sequences from users’ online actions. Standard DNA analysis techniques can then discriminate between genuine and spambot accounts.

Inspired by biological DNA, we model the behaviour of online users as “Digital DNA” sequences, introducing a strikingly novel, simple, and effective approach to discriminate between genuine and spambot online accounts.

Fake followers are those Twitter accounts specifically created to inflate the number of followers of a target account. Fake followers are dangerous for the social platform and beyond, since they may alter concepts like popularity and influence in the...

To visualize post-emergency damage, a crisis-mapping system uses readily available semantic annotators, a machine-learning classifier to analyze relevant tweets, and interactive maps to rank extracted situational information. The system was validated...
