In recent literature, multilayer networks are increasingly being used to model and manage complex scenarios. One of them well suited to be modeled and managed using multilayer networks is represented by multimodal social networks, in which nodes and edges can be of different types. In fact, in this case, each layer of the multilayer network can be used to model one type of nodes in the multimodal social network while the edges of the latter can be represented by intra-layer edges of the former. In this paper, we want to demonstrate the feasibility of this idea by proposing a framework for analyzing multimodal social networks through the analysis of a corresponding multilayer network. In particular, we use our framework to address two challenging issues, namely the evolution of multilayer networks and their resilience to intra- and inter-layer perturbations. After introducing the model and describing the technical details of our framework, we present several experiments that demonstrate the effectiveness of our proposal.
Nella letteratura recente, i multilayer network vengono sempre più utilizzati per modellare e gestire scenari e sistemi complessi, uno dei quali è rappresentato dai multimodal social net- work, ovvero una categoria di reti in cui i nodi e gli archi possono essere di diverse tipologie. In questo caso, ciascun layer del multilayer network può essere utilizzato per modellare un tipo di nodi del multimodal social network. Successivamente, i layer vengono connessi al loro interno da archi intra-layer e al loro esterno da archi inter-layer. In questa tesi, vogliamo dimostrare la realizzabilità di questa idea, proponendo un framework per studiare i multimo- dal social network attraverso l’analisi di un multilayer network ad esso corrispondente. In particolare, utilizziamo il nostro framework per affrontare due questioni significative, ovvero l’evoluzione temporale dei multilayer network e la loro resilienza alle perturbazioni intra- e inter-layer. Dopo aver introdotto il modello e descritto i dettagli tecnici del nostro framework, presentiamo diversi esperimenti che dimostrano l’efficacia del presente studio.

Abstract
In recent literature, multilayer networks are increasingly being used to model and manage complex scenarios. One of them well suited to be modeled and managed using multilayer networks is represented by multimodal social networks, in which nodes and edges can be of different types. In fact, in this case, each layer of the multilayer network can be used to model one type of nodes in the multimodal social network while the edges of the latter can be represented by intra-layer edges of the former. In this paper, we want to demonstrate the feasibility of this idea by proposing a framework for analyzing multimodal social networks through the analysis of a corresponding multilayer network. In particular, we use our framework to address two challenging issues, namely the evolution of multilayer networks and their resilience to intra- and inter-layer perturbations. After introducing the model and describing the technical details of our framework, we present several experiments that demonstrate the effectiveness of our proposal.File | Dimensione | Formato | |
