As Communication Service Providers (CSPs) adopt the Network Function Virtualization (NFV) paradigm they need to transition their network function capacity to a virtualized infrastructure with different Network Functions running on a set of heterogeneous servers. This abstract describes a novel...

We use computers to study economics, but few people realize that we can use economics to study and design computational systems. The reason is that computer networks can be regarded as a community of processes that in their interactions, strategies and lack of perfect knowledge, face the same...

We present a study of the group purchasing behavior of daily deals in Groupon and LivingSocial and introduce a predictive dynamic model of collective attention for group buying behavior. In our model, the aggregate number of purchases at a given time comprises two types of processes: random...

We have conducted three empirical studies of the effects of friend recommendations and general ratings on how online users make choices. We model and quantify how a user deciding between two choices trades off an additional rating star with an additional friend’s recommendation when selecting...

We studied the statistics in the number of visitors to sites of the World Wide Web by examining usage logs covering one hundred and twenty thousand sites. We found out that both in the case of all sites and sites in specific categories, the distribution of visitors per site follows a universal...

The ever-increasing amount of information owing through Social Media forces the members of these networks to compete for attention and influence by relying on other peopleto spread their message. A large study of information propagation within Twitter reveals that the majority of users act as...

In recent years, social media has become ubiquitous and important for social networking and content sharing. And yet, the content that is generated from these websites remains largely untapped. In this paper we demonstrate how social media content can be used to predict real-world outcomes. In...

Scholars, advertisers and political activists see massive online social networks as a representation of social interactions that can be used to study the propagation of ideas, social bond dynamics and viral marketing, among others. But the linked structures of social networks do not reveal...

We analyze the role that popularity and novelty play in attracting the attention of users to dynamic websites. We do so by determining the performance of three different strategies that can be utilized to maximize attention. The first one prioritizes novelty while the second emphasizes...

We present an evolutionary model of technology diffusion in which an old and a new technology are available, both of which improve their performance incrementally over time. Technology adopters make repeated choices between the established and the new technology based on their perceived...
