Social Trust and Desinformation Campaigns

In his talk, Felix Boes will first introduce models of rumour spreading and sybil attack detection. Both research areas examine attacks on trust-based networks, such as online social networks (OSNs). The first area studies the spread and containment of misinformation in a static network, whilst the second aims to detect attacks that have already been carried out by exploiting structural properties or using meta-information.

The main part of the talk will introduce well-known and new structure-based modelling and recognition approaches, which also make use of tools from topological data analysis. In addition to the quality of available datasets, current open questions will be discussed.

Afterwards there will be time for questions and discussion over coffee and tea.
