Mining and analyzing the valuable knowledge hidden behind the amount of data available
in social media is becoming a fundamental prerequisite for any effective and successful …

In recent years, virtual learning environments are gaining more and more momentum,
considering both the technologies deployed in their support and the sheer number of …

Systems that exhibit complex behaviours often contain inherent dynamical structures which
evolve over time in a coordinated way. In this paper, we present a methodology based on …

Abstract Identifying Relevant Sets, ie, variable subsets that exhibit a coordinated behavior, in
complex systems is a very relevant research topic. Systems that exhibit complex dynamics …

Abstract The Relevance Index method has been shown to be effective in identifying
Relevant Sets in complex systems, ie, variable sub-sets that exhibit a coordinated behavior …

Various methods have been proposed to identify emergent dynamical structures in complex
systems. In this paper, we focus on the Dynamical Cluster Index (DCI), a measure based on …

Many complex systems, both natural and artificial, may be represented by networks of
interacting nodes. Nevertheless, it is often difficult to find meaningful correspondences …

Scopus is a well known repository of metadata about scientific research articles. In this work,
we gather data from this repository to create a social graph of scientific authors, starting from …

In many complex systems one observes the formation of medium-level structures, whose
detection could allow a high-level description of the dynamical organization of the system …

The identification of emergent structures in complex dynamical systems is a formidable
challenge. We propose a computationally efficient methodology to address such a …
