• What kind of contents and ideas are being circulated online and how they might influence radicalization ?
• How are they being circulated on the Web ?
• How do they relate to each other in the cyberspace ?
If the Web can be considered as ‘milieu’ for radicalization, then we need to explore :
Introduction
• Most of empirical studies are focusing on the contents of extremist websites / webpages ;
Ex : Kimmage 2008 ; Bowman-Grieve 2009 ; Brachman 2010 ; Mozes & Weimann 2010
• Few empirical studies are looking at the structural patterns of extremist presence online ;
Ex : Reid and Chen 2007 ; Chen, Chung, Qin, Reid, Sageman and Weimann 2008 ; Chen 2011 ; Klausen, Barbieri, Reichlin-Melnick, and Zelin 2012.
Very difficult to gauge precisely the extent of extremist presence online ;

Webometrics studies (Almind et Ingwersen 1997) :
« a set of quantitative and qualitative techniques for tracking and evaluating the impact of web sites and online ideas » :
• Web mention analysis ;• Sentiment analysis ; • Link and hyperlink analysis ; • …
Digital Methods
« Hyperlinks are the glue of these online communities, forming digital footprints of the way individuals make connections. Through a simple selection to include, exclude or just follow a link in our daily online interactions, we passively telegraph the way we see the world, what is important to us, to what degree and why » (Schulman 2008: 147) ;
« Hyperlink is perhaps the most significant mechanism of online gatekeeping » (Napoli 2008 : 18).
Hyperlink analysis : Why ?
•It reveals information about popularity (centrality) on the Web ;
•It reveals information about pattern of linkage (connectivity) on the Web;
Digital Methods
3 methodological steps :
• Collecting hyperlinks or URLs (Navicrawler)
• URLs categorization (Navicrawler)
• Visualization – Graph/Mapping (Gephi)
Hyperlink analysis : How ?

Promises :
• Overall better understanding of the extremist presence online ;
• Clarifying the patterns of cross-linkage between extremist websites (ideological proximity) ;
• Evaluation of the centrality of webpages compared to others (e-reputation) ;
