How can we optimize the topology of a networked system to bring a flu under control, propel
a video to popularity, or stifle a network malware in its infancy? Previous work on information …

Given a social network, can we quickly'zoom-out'of the graph? Is there a smaller equivalent
representation of the graph that preserves its propagation characteristics? Can we group …

Given a graph, like a social/computer network or the blogosphere, in which an infection (or
meme or virus) has been spreading for some time, how to select the k best nodes for …

Given an noisy or sampled snapshot of a network, like a contact-network or the blogosphere,
in which an infection (or meme/virus) has been spreading for some time, what are the best …

Privacy and security are major concerns for many users of social media. When users share
information (eg, data and photos) with friends, they can make their friends vulnerable to …

The spread of epidemics and malware is commonly modeled by diffusion processes on
networks. Protective interventions such as vaccinations or installing anti-virus software are …

While static epidemic control, eg using vaccination, has been extensively studied for various
network types, controlling epidemics dynamically remains an open issue. In this work, we …

In this paper, we analyze the quality of a large class of simple dynamic resource allocation
(DRA) strategies which we name priority planning. Their aim is to control an undesired …

Today's social and internet networks contain millions or even billions of nodes, and copious
amounts of side information (context) such as text, attribute, temporal, image and video data …

Social media has changed the way people interact with each other and has contributed
greatly towards bringing people together. It has become an ideal platform for people to …
