1. Clustering and Evolution of Social Networks StudentBII: Nuno Moreira Teachers: Profª Paula Brito e Profº Pedro Campos

2. Thecontext Taking into account the gaining importance of the social networks on our days and the also increasing computational capacity we propose ourselves to study the dynamics of this networks

3. Objectives Analyze social networks, namely the relationship of friends in Palco Principal, and group the vertices of the network Moreover, its our objective to study the dynamic of such network through time

4. Theapproach To analyze this large network we are going to use the software Pajek “Pajek is a program, for Windows, for analysis and visualization of large networks having some thousands or even millionsofvertices.”(FromPajek- Manual)

5. Current Situation Finishing the treatment and the extraction of the data (users profiles and friends) using the software R and Microsoft Access 2007 Starting to use the software Pajek to represent the network in a very near future
