What was the paper about?
The paper discusses research into the interactions between members of extreme right communities on twitter, and how these groups interact between countries. The extremist groups included fascist, racist, supremacist, extreme nation-alist or neo-Nazi nature, or a combination, from eight different countries.
The research created follower and interaction graph networks for extremist social media accounts and illustrated, identified numerous extremist groups and indicated the level of interaction between them.
- Reciprocal follower and interaction relationships were used to identify communities (OSLOM algorithm)
- Nationality or linguistic proximity was used to indicate national boundaries
- Latent topic detection, Non-negative matrix factorization (NMF), of tweet messages was used to identify the views of each community
The paper concludes that the use of social extremist groups of social media is becoming increasingly active, but doesn't provide evidence of this. But, the paper does identify the existence of stable communities of extremist groups within nationalistic boundaries.
