Understanding the structure of extremist propaganda on Twitter

Abstract

Extremist groups are using Twitter as a major resonance loud speaker to relay their propaganda. This talk will describe the state of the art in large graph data mining. It will in particular discuss about the practical application of community detection and graph clustering techniques, the deep relations that exist between these problems and convex-optimization, and extension to cases where we have more than a single graph to do the analysis. In particular we will describe multi-graph clustering and present new methods for cushioning information coming from different graphs.
