Evaluating Similarity Measures for Emergent Semantics of Social Tagging (2009)
Benjamin Markines, Ciro Cattuto, Dominik Benz, Andreas Hotho, Gerd Stumme
Social bookmarking systems and their emergent information structures, known as folksonomies, are increasingly important data sources for Semantic Web applications. A key question for harvesting...

Emergent Community Structure in Social Tagging Systems (2008)
Cattuto, Ciro, Baldassarri, Andrea, Servedio, Vito D. P., Loreto, Vittorio
A distributed classification paradigm known as collaborative tagging has been widely adopted in new Web applications designed to manage and share online resources. Users of these applications...
High resolution dynamical mapping of social interactions with active RFID (2008)
Barrat, Alain, Cattuto, Ciro, Colizza, Vittoria, Pinton, Jean-Francois, Broeck, Wouter Van Den, Vespignani, Alessandro
In this paper we present an experimental framework to gather data on face-to-face social interactions between individuals, with a high spatial and temporal resolution. We use active Radio Frequency...
Semantic Analysis of Tag Similarity Measures in Collaborative Tagging Systems (2008)
Cattuto, Ciro, Benz, Dominik, Hotho, Andreas, Stumme, Gerd
Social bookmarking systems allow users to organise collections of resources on the Web in a collaborative fashion. The increasing popularity of these systems as well as first insights into their...
ABSTRACT Network Properties of Folksonomies (2008)
Christoph Schmitz, Miranda Grahl, Andreas Hotho, Gerd Stumme, Ciro Cattuto, Andrea Baldassarri, ...
Social resource sharing systems like YouTube and del.icio.us have acquired a large number of users within the last few years. They provide rich resources for data analysis, information retrieval, and...

Passant, Alexandre, Mulvany, Ian, Mika, Peter, Maisonneauve, Nicolas, Löser, Alexander, Cattuto, Ciro, ...
A common social problem at an event in which people do not personally know all of the other participants is the natural tendency for cliques to form and for discussions to mainly happen between...

Vocabulary growth in collaborative tagging systems (2007)
Cattuto, Ciro, Baldassarri, Andrea, Servedio, Vito D. P., Loreto, Vittorio
We analyze a large-scale snapshot of del.icio.us and investigate how the number of different tags in the system grows as a function of a suitably defined notion of time. We study the temporal...

Collaborative Tagging and Semiotic Dynamics (2006)
Cattuto, Ciro, Loreto, Vittorio, Pietronero, Luciano
Collaborative tagging has been quickly gaining ground because of its ability to recruit the activity of web users into effectively organizing and sharing vast amounts of information. Here we collect...
Bistable Clustering in Driven Granular Mixtures (2005)
