Having a large, unexplored and partially unknown solution spaces, deliberations on complex problems require the contribution of big communities which can come together through online media. However current tools do not perform well enough, particularly when a controversial topic is discussed. At this point argumentation arises as an option. However there is need to verify its utility also because argumentation does not fit in the way we are used to reason in our daily lives. To do that, among various criteria, the one we are dealing with is whether it can mediate the exchange of ideas and knowledge. This can be analyzed referring to the common ground theory. However this theory is mostly examined in a conversational context which is not necessarily adaptable to an online, asynchronous deliberation. Thus this work is an attempt in observing common ground characteristics in such context as a step to develop measures for evaluation in the long term. We make use of clustering and social network theory for this purpose. The deliberations in question here are on the future of biofuels in Italy and have been conducted through an argumentation based platform called Deliberatorium.
