Construction of Directed 2K Graphs

Bálint Tillman, Athina Markopoulou, Carter T. Butts +1

We study the problem of constructing synthetic graphs that resemble real-world directed graphs in terms of their degree correlations. We define the problem of directed 2K construct…

Estimating Subgraph Frequencies with or without Attributes from Egocentrically Sampled Data

Minas Gjoka, Emily Smith, Carter T. Butts

In this paper we show how to efficiently produce unbiased estimates of subgraph frequencies from a probability sample of egocentric networks (i.e., focal nodes, their neighbors, an…

Estimating Clique Composition and Size Distributions from Sampled Network Data

Minas Gjoka, Emily Smith, Carter T. Butts

Cliques are defined as complete graphs or subgraphs; they are the strongest form of cohesive subgroup, and are of interest in both social science and engineering contexts. In this…

2.5K-Graphs: from Sampling to Generation

Minas Gjoka, Maciej Kurant, Athina Markopoulou

Understanding network structure and having access to realistic graphs plays a central role in computer and social networks research. In this paper, we propose a complete, and pract…

Coarse-Grained Topology Estimation via Graph Sampling

Maciej Kurant, Minas Gjoka, Yan Wang +3

Many online networks are measured and studied via sampling techniques, which typically collect a relatively small fraction of nodes and their associated edges. Past work in this ar…

Walking on a Graph with a Magnifying Glass: Stratified Sampling via Weighted Random Walks

M. Kurant, M. Gjoka, C. T. Butts +1

Our objective is to sample the node set of a large unknown graph via crawling, to accurately estimate a given metric of interest. We design a random walk on an appropriately define…
