Empirical studies of computer mediated conversations and debates have presented methodological proposals of qualitative analysis that focus on the original elements of communicative and social dynamics of these exchanges. Recent works have investigated how online political deliberation can be analyzed presenting multiple variables capable of showing how these exchanges could contribute to widen deliberative processes concerning specific questions. I present some methodological models of qualitative analysis of online deliberation processes by making a synthesis of their main characteristics. I argue that this analysis cannot be reduced to the inquiry on the argumentative exchange. It is necessary to observe the situations and the contexts of sociability in which the interactions take place as well as the construction and negotiation of the rules that will govern interlocutors' interactions.
