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...
Analyzing Tag Semantics Across Collaborative Tagging Systems (2008)
Benz, Dominik, Grobelnik, Marko, Hotho, Andreas, Jaschke, Robert, Mladenic, Dunja, Servedio, Vito D. P., ...
The objective of our group was to exploit state-of-the-art Information Retrieval methods for finding associations and dependencies between tags, capturing and representing differences in tagging...

Molecular Dynamics Simulation of Vascular Network Formation (2007)
Buttà, Paolo, Cerreti, Fiammetta, Servedio, Vito D. P., Triolo, Livio
Endothelial cells are responsible for the formation of the capillary blood vessel network. We describe a system of endothelial cells by means of two-dimensional molecular dynamics simulations of...
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...
Folksonomies, the Semantic Web, and Movie Recommendation (2007)
Szomszor, Martin, Cattuto, Ciro, Alani, Harith, O’Hara, Kieron, Baldassarri, Andrea, Loreto, Vittorio, ...
While the Semantic Web has evolved to support the meaningful exchange of heterogeneous data through shared and controlled conceptualisations, Web 2.0 has demonstrated that large-scale community...

Detecting communities in large networks (2004)
Capocci, Andrea, Servedio, Vito D. P., Caldarelli, Guido, Colaiori, Francesca
We develop an algorithm to detect community structure in complex networks. The algorithm is based on spectral methods and takes into account weights and links orientations. Since the method detects...
Caldarelli, Guido, Cartozo, Cecile Caretta, Rios, Paolo De Los, Servedio, Vito D. P.
The widespread occurrence of an inverse square relation in the hierarchical distribution of sub-communities within communities (or sub-species within species) has been recently invoked as a signature...
The scale-free topology of market investments (2003)
Garlaschelli, Diego, Battiston, Stefano, Castri, Maurizio, Servedio, Vito D. P., Caldarelli, Guido
We propose a network description of large market investments, where both stocks and shareholders are represented as vertices connected by weighted links corresponding to shareholdings. In this...
Vertex Intrinsic Fitness: How to Produce Arbitrary Scale-Free Networks (2003)
Servedio, Vito D. P., Caldarelli, Guido, Butta`, Paolo
We study a recent model of random networks based on the presence of an intrinsic character of the vertices called fitness. The vertices fitnesses are drawn from a given probability distribution...
