Abstract: The amount of citizens’ participation and political involvement within democratic societies may vary from one person to another. Similarly, this diversity of political engagement of users might be observed in online platforms such as Twitter. Hence, considering their political-related online activity, they may be cataloged as highly politically active or poorly politically active citizens. The aim of this tutorial is to provide the ICEDEG audience with an overview of the use of social media data for E-Government and data mining strategies to model users’ interests. Specifically, I will present an approach to measure their degree of interest in politics. In the first part of the tutorial, I will introduce the issues related to the supporting role of Online Social Networks (OSNs) in citizenship evolution. Then, we will see techniques employed to model users’ preferences as well as tweets classification and clustering to do so. Considering Twitter as a widely studied platform in digital citizenship, I will present relevant works in the state of the art. In the second part of the tutorial, we will analyze a case study taking the advantage of a demo. Finally, to conclude, I will present emerging aspects, open issues and challenges in this area.
OSNs have shown to be helpful to build a citizen identity for users. For instance, Twitter has proved to be a useful media platform that facilitates forms of political expression for its users. However, considering the extent of content published every second, the dynamic linkage among users and the wide purpose-oriented nature of Twitter, it is difficult to define the degree of political participation or interest of a digital citizen. Being able to solve this issue is of interest in government and society data management, and more generally in recommender systems research.
Digital citizenship in OSNs (20 min). Digital citizenship is the ability to use technology to obtain political information. Besides, the frequent use of it elicits the online participation of individuals in society . The impact of OSNs in civic engagement, democratic participation, political party supporters interaction and voting is evident in recent years. People enjoy using the Internet and may benefit from it through the opportunity it offers of letting them participate fully in society.
