In the analysis of large-scale social networks, a central problem is how to discover how members of the network to be analyzed are related. Instant messaging (IM) is a popular and relatively new form of social interaction. In this paper we study IM communities as social networks. An obvious barrier to such a study is that there is no de facto measure for(More)
In this paper, we present MARKETECTURE, an agent-based, microeconomic, scalable model for studying deregulated power markets. Features that distinguish it from previously studied models include: the ability to generate individualistic, demographics based, elastic demand profiles; a highly configurable system that supports different matching algorithms for(More)
The e-NABLE movement is a global confederation that designs, builds, and distributes free, 3D-printed, upper limb assistive devices to children born without fingers and hands. It has been called one of the most inspiring philanthropic efforts of the 21st century. We use social network analysis and natural language processing on the original e-NABLE Google+(More)

Given a p-order A over a universe of strings (i.e., a transitive, reflexive, antisymmetric relation such that if (x, y) ∈ A then |x| is polynomially bounded by |y|), an interval size function of A returns, for each string x in the universe, the number of strings in the interval between strings b(x) and t(x) (with respect to A), where b(x) and t(x) are(More)
Twitter is a platform where people voice their thoughts to the world. There are five million tweets per hour. If we can classify the social media users by where they live, these thoughts can give insight to human behavior and interactions on a community level. However, most users do not provide any explicit location information. As a result, the task of(More)
