The cluster structure of many real-world graphs is of great interest, as the clusters may correspond e.g. to communities in social networks or to cohesive modules in software syst...
Recent technologies supporting continuous connectivity enable sustained awareness within social networks, which eventually boosts interaction and therefore the need of individuals...
Mobile social networks have been introduced as a new efficient (i.e., minimize resource usage) and effective (i.e., maximize the number of target recipients) way to disseminate con...
Today, a number of algorithms exist for constructing tag hierarchies from social tagging data. While these algorithms were designed with ontological goals in mind, we know very li...
Abstract. The challenge of making a virtual world believable includes a requirement for AI entities which autonomously react to a dynamic environment. After the breakthroughs in be...
