We proposed a model of social network and of the propagation of discussions and information (for more information social networks and information propagagtion , pdf format 1066ko). 

Moreover, a social influence takes place when agents discuss. This model is innovative with different respects : in particular, it is based on continuous, uncertain opinions. We proposed particular dynamics which take into account the higher influence of more certain people (see : Social influences for more information).

We studied the behaviour of the model coupling the different parts through parameter exploration and sensitivity analysis (see : Exploration of the global model for more information).
