Rogue algorithms

In this project, funded bij the SIDN, we investigate the spread of disinformation and evaluate the role of algorithms in this spread.


The end product of this project is a network graph that displays the largest spreaders of disinformation, specifically how much of their content is original and how much is copied from other sources, and which sources.


The tool is publicly available at While the data is incomplete, our tool gives some insight into the relationships between websites based on disinformation content.

Algorithms that copy or steal content often try to hide their tracks, for example by employing machine translations or using synonyms. Using advanced AI techniques we attempt to recognize these copies and follow their spread.
