The idea of analyzing social networks arises from the logic of understanding them as a new form of political participation, therefore, as a new form of communication and organization of citizens.

In this paper, we investigate a method for constructing cascades of information co-occurrence, which is suitable to trace emergent structures in information in scenarios where rich contextual features are unavailable. Our method relies only on the temporal order of content-sharing activities, and intrinsic properties of the shared content itself. We apply this method to analyse information dissemination...
In this paper we present a framework that extracts meaningful knowledge from microposts shared in social platforms in order to build user profiles. This process involves different steps for the analysis of such microposts (extraction of keywords, named entities and their matching to ontological concepts) and their weighting. The concept weighting involves different scores, such as sentiment analysis...
Although microblogging has become a global phenomenon, there has been surprisingly little research on the subject. Thus, this paper aims to serve as an exploratory study that probes into microblogging user behaviors. This study suggests that users' cognitive processes and use of technology can be explained from the perspective of technology sensemaking. Thus, this study treats Plurk as the target,...
